Multiple search queries on one page
I need to display results of three different search queries on one page. More precisely, there is a searchbox on my page where a user enters a search phrase. Once the search phrase is submitted, I need to take the generated WP search query and modify it to build three different custom queries.
The results of these three queries will be then displayed on a page in separate blocks.
So for example, a user searches for the 'Honda' phrase. Then he gets the results of three search queries:
1. 'Honda' in custom posts called 'Cars',
2. 'Honda' in custom posts called 'Motorbikes',
3. 'Honda' in custom posts called 'Tracks',
I know that the simplest way to modify a WP search query is to use the `pre_get_posts` action hook, but I'm not sure how I can use it to create three separate queries.
Your advice will be much appreciated. | You can use `pre_get_posts` to modify the main query, but you will need to create new queries for the other searches. Use `get_query_var('s')` to get the search terms and create new `WP_Query` objects to perform your search.

Strange Search Queries in Apache Status
I am running a wordpress website with high traffic, my server load gets very high and while checking apache status i found flood of wordpress searches like this
/?s=\"khabarnaak\"&id=39790 HTTP/1.0
Now this doesn't looks like a normal search, is this some kind of attack ? or some issue with plugin ? How can i dig into it or find a root cause | I'm sure you've googled 'khabarnaak' - it's a Pakistani talk show.
It's more likely to be an automated scraper trying to find content rather than an attack. The request does not look like it has been crafted for a Wordpress site.
Two ways to stop it are:
* Block the IPs making the request. Add 'Deny from XX.XX.XX.XX' to your htaccess file, replacing XX.XX.XX.XX with the IP address. You need to be careful that you don't block valid requests using this method by checking the logs
* Block the request itself. Add the following to your htaccess file:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{QUERY_STRING} ^.*(s=\"khabarnaak\").* [NC]
RewriteRule ^(.*)$ - [F,L]
</IfModule>

Possibility of Synchronized and Exactly Same Multiple Sites via WordPress Multisite
I did read the documentation and I believe that I couldn't find this information there. I would like to know that if it is possible that I can have multiple site's content (pages, posts and all the database stuff) fully synchronized, such that all posts, pages CRUD in one site, leads to changes in the other sites. Only things that I don't need synchronized is:-
1. Site specific CSS (which is resolved, thanks to wp stackexchange.)
2. Site specific sub domain. | You may find the ThreeWP Broadcast plugin useful. It takes care of "broadcasting" new posts/pages and updates to them to (any or all) sites in a WordPress MultiSite installation.

How to pass a specific post id from "all posts" list in Admin panel
I want to add a custom column to the "all posts" list display in admin. I can add the custom column but my problem is I don't know how to tie the post ID to each listing on the page. The custom column will contain a hyperlink to a php file that will display details about each particular post in the list.
Example POST 123
<a href="myphpcode.php?post=123" >Show Details</a>
Can I use $post->ID or something like that to get the post ID into the link? | Assuming you've added the column correctly and not hacked it in somehow, then the `manage_${post_type}_posts_custom_column` filter should do what you want. The example in the Codex is about the best I've got given the sparcity of information in the question:
add_action( 'manage_posts_custom_column' , 'custom_columns', 10, 2 );
function custom_columns( $column, $post_id ) {
switch ( $column ) {
case 'book_author' :
$terms = get_the_term_list( $post_id , 'book_author' , '' , ',' , '' );
if ( is_string( $terms ) )
echo $terms;
else
_e( 'Unable to get author(s)', 'your_text_domain' );
break;
case 'publisher' :
echo get_post_meta( $post_id , 'publisher' , true );
break;
}
}

Multiple Post Status
How can I assigned a post to multiple post status like it will be in 'publish' status and also a custom post status say 'hide' post status.
by this publish post count will remain same and 'hide' post status can be hide from a loop.
How can this be achieved? | > How can I assigned a post to multiple post status like it will be in 'publish' status and also a custom post status say 'hide' post status.
This can be achieved by storing a post meta value. You can do stuff on the post based on this meta value.
> by this publish post count will remain same
The meta value won't change post count.
> 'hide' post status can be hide from a loop.

Theme Customizer for only author.php (per user baisi)
How can the Wordpress Theme Customizer be used only for `author.php` and settings will be saved per user basis. By which every user can customize their own `author.php`.
How can it be achieved? | First, you will need to generate customizer settings depending on the current user. So there are two conditions to be met: the setting must only be accessible to the current user and this setting must be unique to him.
// Only do this for contributors and up
if (current_user_can('edit_posts')) {
// retrieve author id
global $current_user;
get_currentuserinfo();
$author_id = $current_user->ID
// generate customizer setting for this author only
$wp_customize->add_setting( 'header_color_' . $author_id , array(
'default' => '#000',
'sanitize_callback' => 'sanitize_hex_color',
'capability' => 'edit_posts',
));
In (the heading of) your `author.php` you will need to get the id of the author of the current page to retrieve the relevant mod.
$author_id = get_the_author_meta('ID');
get_mod('header_color_' . $author_id); | stackexchange-wordpress | {

Show excerpt if no title in admin view
Usually my posts do not have a title, so in the admin view it always says "(no title)" wherever the title would be shown.
So I am wondering how I could hook into that view function. I would like to check whether the post has no title, and if so, show a custom length excerpt of lets say the first 10 words of the post instead. But only in the admin view, so that in the frontend it only shows a title if there actually is one.
How would I do this? | You can try the following approach using the `the_title` filter in the `edit.php` screen:
/**
* Modify post titles in the edit.php screen.
* If the post title is empty, then show max 10 words from the post content instead.
*/
add_action( 'load-edit.php', function()
{
add_filter( 'the_title', function( $title )
{
$post = get_post();
if( is_a( $post, '\WP_Post' ) && ! $post->post_title && $post->post_content )
$title = wp_trim_words( strip_shortcodes( strip_tags( $post->post_content ) ), 10 );
return $title;
} );
} );
where we display max 10 words from the post content if the title is empty. | stackexchange-wordpress | {

Hook for when a page template is changed
I know that you can remove the editor section of the page editor page ( :/) depending on the template chosen using `add_action( 'load-page.php', 'hide_editor_function' );` (with proper functionality of course). The problem with this though, as you should be able to tell, is that this will only work on a page load/reload. Not as soon as the template is changed.
As far as I can find, there is no specific hook for this. So my question really is, is there a hook for when the user changes the page template for a page in the admin panel? And if not, what would be the best way to have 'instantaneous' hiding/revealing of the editor (and add custom meta boxes)?
Thank you for your time, Lyphiix | If you want to toggle the editor "on the fly", you'll need to revert to a pure JavaScript solution, and only ever "visually" hide it (as opposed to removing it server-side):
function wpse_189693_hide_on_template_toggle() {
$screen = get_current_screen();
if ( $screen && $screen->id === 'page' ) :
?>
<script>
jQuery( "#page_template" ).change(
function() {
jQuery( "#postdivrich" ).toggle( jQuery( this ).val() === "my-template.php" );
}
).trigger( "change" );
</script>
<?php
endif;
}
add_action( 'admin_print_footer_scripts', 'wpse_189693_hide_on_template_toggle' );
The reason you can't keep your `hide_editor_function` is, whilst this will work to initially hide the editor, once the user saves and reloads the page the editor will no longer be in the source to "toggle". So it always has to be there, even if it's just hidden. | stackexchange-wordpress | {

Is it possible to change image urls by hooks?
I have moved my uploads directory to another server. For example, a url that was pointing to:
<
should point to here in the new situation:
<
I know I could do this by a rewrite rule or by a database search and replace, but for various reasons this is not what we want.
Now I know that it is possible to change the urls of posts etc. by using the filter hooks post_link, page_link and post_type_link. I was wondering, is there also a hook that can be used for changing image urls when they are requested from the system?
I primarily focus on the urls for featured images and such, as images in the post content are plain text in the database.
Regards, Joost. | As you want to change (use different) URL for featured image only, you can use `pre_option_upload_url_path` hook.
// Setting the uploads directory URL
function wpse_change_featured_img_url() {
return '
}
add_filter( 'pre_option_upload_url_path', 'wpse_change_featured_img_url' );
This hook will not change URLs permanently but it will set uploads directory to some different URL temporally.
This will also not change URL of post images, you will have to change them manually or with SQL query. | stackexchange-wordpress | {

Why won't my custom login page CSS load?
Hoping for some help here as I'm scratching my head. I'm trying to create a custom login page for my site which has gone rather well until I try to add in a custom CSS to make it look pretty. I'm trying to add in the style-login.css file using the following:

Post titles not letting me use 2 consecutive dashes in permalink
I have a site where YouTube video IDs are used as a post's title. This mostly works fine, except some valid YouTube video IDs have two consecutive dashes. For example, "j--c0wP54JU" is getting automatically modified by wordpress to be "j-c0wP54JU" (Note the single dash).
When I try to manually edit the permalink from the Edit Post page, it keeps removing the 2 consecutive dashes when I press OK.
Where can I disable this part of Wordpress that changes the URLs to be "web safe"? | Regarding the **why** part, I think I've traced this to the following line:
$title = preg_replace('|-+|', '-', $title);
within the `sanitize_title_with_dashes()` function.
It's added to the `santize_title()` via the filter:
add_filter( 'sanitize_title', 'sanitize_title_with_dashes', 10, 3 );
but I wouldn't recommend removing it totally.
## Update:
Here's a quick and dirty way around this:
add_filter( 'sanitize_title', function( $title )
{
return str_replace( '--', 'twotempdashes', $title );
},9 );
add_filter( 'sanitize_title', function( $title )
{
return str_replace( 'twotempdashes', '--', $title );
},11 );
where we replace two dashes into some temporary string, before the `sanitize_title_with_dashes` is activated and then replace the string again to two dashes afterwards. We could adjust this to the more general case, but you get the idea ;-) | stackexchange-wordpress | {

return $normalized_term;

How many security plugins are too many?

3. One sends you an email when your PHP version is behind the latest security release.

But having three plugins active that do _all of these things_ (and usually a lot of nonsense for their feature list) is bad.
Do not install plugins with overlapping responsibilities. It doesn’t matter whether for security, SEO or performance.

echo '<meta name="citation_title" content="' . the_title( '', '' ).'" />' . '';
} ?>
but the result was a title before the meta:
single post title is here<meta name="citation_title" content="" />
any help please? | Use `the_title_attribute()` to print the attribute. A post title might contain HTML, so you need the escaped content that this function returns.
Also suppress immediate print-out, because that will set the output in front of the `echo` statement.
if ( is_singular( 'communications' ) ) {
$title = the_title_attribute( [ 'echo' => FALSE ] );
echo '<meta name="citation_title" content="' . $title . '" />' . PHP_EOL;
}
Another question is why your theme knows so much about the post type. Custom post types should always be registered in a plugin. So that code should go to the plugin too. This is how the result could look like:
add_action( 'wp_head', 'add_citation_title' );
function add_citation_title() {
if ( ! is_singular( 'communications' ) )
return;
$title = the_title_attribute( [ 'echo' => FALSE ] );
echo '<meta name="citation_title" content="' . $title . '" />' . PHP_EOL;

Why isn't add_image_size('event-secondary-image-thumbnail', 250, 150) working?

How to display all images "Uploaded By" an author
I have multiple users, that have the ability to upload media. When I look at the media library it shows the file information, and included at the bottom is an "Uploaded By 'username'"
How can I use this username to loop through the media library and display all images from a user?
Here's a picture of the information with the media.
!media name | You can do it via WP_Query loop:

Is it mandatory to use $wpdb->prefix in custom tables
Sorry if this question is trivial. I'm just beginning to develop plugins in WordPress.
In all the tutorials I found this: while creating the custom tables, `$wpdb->prefix` is used.
Example:
$table_name = $wpdb->prefix . "liveshoutbox";
My question:
> Is it mandatory to use `$wpdb->prefix`? What happens If I don't use prefix for my custom tables? | It is mandatory, though it is not enforced.
Consider the scenario when two Wordpress site has been setup in the same database. One with prefix `wp_` and another with `wp2_`. If you install your plugin in both of the sites with the prefix, your created tables will be `wp_liveshoutbox` for first site and `wp2_liveshoutbox` for the second site. But if you omit the prefix, both of the site will be using the same table named `liveshoutbox` and the whole thing will break up. | stackexchange-wordpress | {

Should we explicitely enqueue jQuery and our theme's main stylesheet?
I noticed that if I don't explicitely enqueue my theme's main stylesheet and jQuery in my functions.php, these are loaded anyway. But perhaps it's better for some reason to enqueue them ? What is the right way of doing it ? | jQuery is there because something else, probably a plugin, enqueued it. The enqueue API won't load it twice, so if you need it you need to ask for it.
The "right way" is to tell WP what you need, and let WP work out the dependencies and duplicates.
Now, there is a rather large "but" here. I've seen plenty of WP installs that have a dozen style sheets and a too-long-to-count list of included javascript. If you want to slow a site down, this is a good way to do it. There is an efficient way to develop and distribute themes/plugins, and that is to use the enqueue process. There is an efficient way to operate a website, and that is to reduce the number of http requests to the absolute minimum needed. That's what caching systems do, and they sometimes hook into the (drumroll please) enqueue process. | stackexchange-wordpress | {

Remove dimensions from filename featured image
I have a problem with a featured image. It's a gif, but when I add it, Wordpress adds the dimensions to the filename, which breaks the gif (since then it's not really a gif anymore).
Is there a way to disable the addition of dimensions to the filename for only the featured image?
The link to my image is: ` The link to my image after selecting it as a featured image is: `
I guess Wordpress is making a thumbnail of my image, but I don't want and need that, since I want the gif to be moving and on the front page.
I remember having no problem at all with this in the past, but now Wordpress adds the dimensions, breaking the GIF in the process. | In addition to creating additional dimension, Wordpress does keep your original image. Your original image is in this link `
So, instead of stopping Wordpress from creating additional dimension, you should retrieve the full image when displaying the featured image. You can get the full image with this -
the_post_thumbnail('full');
In your case, change
<?php the_post_thumbnail('featured-image', array('class' => 'featured-full-width-top')); ?>
to
<?php the_post_thumbnail('full', array('class' => 'featured-full-width-top')); ?>

php if username is role
I know you can easily display custom content if a certain logged in user is a certain role using
<?php if ( current_user_can('contributor') ) : ?>
media files loop
<?php endif; ?>
However, I want to do the same thing, but for a specific username, not the logged in user.
I have user profiles in my wordpress website, some of them are artists, and If the profile being viewed is an artist I want to display their uploaded media. (and nothing to be returned if that profile being viewed is another role.)
I have the variable to get the currently viewed profiles username, I just need the if statement.
Something like:
media files loop | Chris Haugen,
You need to check user role who have 'artist' role and then you need to act on some video loop stuff.
Here's the solution:
$user = get_user_by('login', $username );
if ( !empty( $user->roles ) && is_array( $user->roles ) ) {
foreach ( $user->roles as $role ){
if($role == 'artist')
media files loop
}
}
get_user_by() is return user data of passed 'username'.

Custom post order returning posts from other categories

// if no thumbnail then just print title as usual ?>

Post as frontpage - avoid duplicate content

Any help or pointers into the right direction would make me really happy. | Your best way would be to redirect to the theme's 404 page in the event that the page being loaded matches the slug that you are referring to. Try this:

Exclude posts that only have the 'Uncategorized' category

$args = array ('exclude'=>1,'fields'=>'ids');

But when an admin visit to the site, still it shows custom theme not the `twenty fifteen` Why it is not switched to `twenty fifteen` theme when an admin visit to the site? | You are sort of doing this in a roundabout way. WordPress has a function called `switch_theme()`:

if ( current_user_can( 'manage_options' ) ) {
switch_theme('twentytwelve');
} else {

function wpd_parse_request( $request ){
echo $request->matched_query;

Plugin working on my local installation but Cannot be activated online
Good Day Everyone,
I want to test my Plugin online on my real website but I don't know why, the following line would give an error, when on my local installation everything works perfectly. (I tried to deactivate and reactivate on my local install and I don't get the error).
Both are using the latest version of WordPress (4.2.2)
add_action('wp_enqueue_scripts', 'plugin_jquery');
function plugin_jquery()
{
if (!is_admin())
wp_enqueue_script('plugin-jquery', plugins_url('js/plugin_regpage.js', __FILE__), ['jquery'], true);
wp_enqueue_style(
'plugin-regpage-css',
plugins_url('css/plugin_regpage.css', __FILE__)
);
}
I get:
> Parse error: syntax error, unexpected '[' in html/wp-content/plugins/plugin/plugin.php on line 49
Why would a bracket make a problem online and not locally? | This is an issue with your PHP versions on your local and live install.
The new short array syntax (`[]`) was implemented in PHP 5.4. This tells you that your PHP version on your local install is at least PHP 5.4 and your live install has a version older than that. The new short array syntax will lead to a PHP error in older versions as it is invalid PHP in the older versions.
## SOLUTION
As PHP 5.3 was EOL'ed almost a year ago, it is a very good and security wise idea to ask your host to upgrade their PHP version to atleast PHP 5.4. Alternatively, you can change your new short array syntax back to the old array syntax.
['jquery']
then becomes

Is it OK to use a system cron to trigger a function hooked into the AJAX API
I have a real cron job setup and it seems to work. I have outlined the basics below.
The reason I ask is I don't see this method mentioned often and I'm wondering if that is because doing so is a bad idea?
I don't want to use `wp-cron` and disabling `wp-cron` on my site causes problems in other places (* even while using a real cron to run `/wp-cron.php?doing_wp_cron`)
**Below is an example of what I'm doing:**
**Function**
add_action('wp_ajax_my_function', 'my_function');
add_action( 'wp_ajax_nopriv_my_function', 'my_function' );
my_function() {
...stuff
}
**Url** `wp-admin/admin-ajax.php?action=my_function`
**Cron** `*/45 12-23 * * * wget > /dev/null` | You are using the system `cron` to trigger a function hooked into the AJAX API, not, as your title reads, using "`admin-ajax.php` to run a real `cron` job". You are doing exactly the opposite of what you wrote in the title (I'd advise editing that).
Yes, that is perfectly fine. I have advised using the same technique in fact. All you are doing is making a request to the server on an accurately timed schedule, instead of waiting for a random request from the web.

Test for if you're on 1st page of paginated post (with nextpage quicktag)
I'm developing a site that involves a lot of long posts I'd like to break up using the nextpage quicktag. On the first page there's a large splash photo in the header that I'd like to disappear on subsequent pages—so I need some way of testing if the user is on the first page. I did find this code:
`if ( isset($wp_query->query_vars['page'] ) )`

is .maintenance file still valid for putting WP in maintenance mode?
I see that upon upgrades the .maintenance file is deleted, if present. Is it still a viable/correct way to put WP in maintenance mode? | Not really.
`.maintenance` is a temporary file, not viable if you want to put your site in maintenance mode for a long time.
If you look at source the maintenance mode is maintained only if `$upgrading` variable defined in the file is no older than 10 minutes.
It means `.maintenance` is a sort of _lock file_ when WordPress is upgrading plugins, themes or itself, something that should not last more than 10 minutes.
Surely is possible to insert into that file something like:
$upgrading = time();
And in theory hold WordPress in maintenance mode, but once it is intended to be a temporary file, WordPress feels free to delete the file after a successfull update.
For a long-duration maintenance mode you need to use a different solution.

Feed, RSS not able to clear the cache and cannot change the limit of cache life time
The WordPress Feed system is EXTREMELY complex for no reason.
I have been going around and around and around in circles.
I am using:
function do_not_cache_feeds(&$feed) {
$feed->enable_cache(false);
}
add_action( 'wp_feed_options', 'do_not_cache_feeds' );
define( 'MAGPIE_CACHE_AGE', 1 );
function prefix_set_feed_cache_time( $seconds ) {
return 1;
}
add_filter( 'wp_feed_cache_transient_lifetime' , 'prefix_set_feed_cache_time' );
In my functions.php file in my themes folder.
Did not work for a reason that is beyond me.
So first questions is: Is there any way I can get rid of the caching of the feed? I am already using Varnish?
Second, for the current cached feeds how can I clear them?
Third, where the hell are they been stored? I literally look everywhere. | If you are using W3 Total Cache or any other caching system make sure it does not cache the feeds.
WordPress uses SimplePie for parsing it's feeds. They are many things that are happening at the same time that can cause some confusion. First SimplePie does cache the feeds, I haven't figured yet how to clear it or where it is stored. But you can use this code to force it to not cache it or cache the feeds for a shorter time.
function do_not_cache_feeds(&$feed) {
$feed->enable_cache(false);
}
add_action( 'wp_feed_options', 'do_not_cache_feeds' );
function prefix_set_feed_cache_time( $seconds ) {
return 1;
}
add_filter( 'wp_feed_cache_transient_lifetime' , 'prefix_set_feed_cache_time' );

w3 total cache keeps minifying my feeds
When I deactivate w3 total cache my feed is not minify. But when I bring it back it does. Even when I uncheck: Cache feeds: site, categories, tags, comments. In Page Cache setting of the plugin.
Is there something else I am missing here? | To stop W3 Total Cache from minifying the feeds you need to go to:
1. **In the menu:** Performance > Minify
2. **Meta Box:** HTML & XML > HTML minify settings:

Add custom parameters to JSON API search query?
I am using JSON API plugin to query wordpress from a mobile app.
Currently I have a theme on my wordpress site which works as a directory returning "near me" results when a search is made. This is done using a custom search function builtin in the theme.
The function uses custom parameters to get the `lat/lon` of the user and compare it to the lat/lon of each place in the wp database to sort results by distance.
The issue I am having is that when I run the `get_search_results` method from the `JSON API plugin` the custom parameters are ignored.
Does anyone know if there is anyway I can extend the plugin to return the same results the theme is returning when performing a search.
The plugin seems to have a way to extend controllers, but I can't seem to get my head around on how to use that to customize the search query.
Any tip putting me in the right direction will be appreciated.

Should there be a trailing slash in the permalink
Which WordPress permalink structure is better in terms of performance and SEO:
`/%post_id%/%postname%`
or
`/%post_id%/%postname%/`
Does it matter?
Google has big discussion here. But it's not from a WordPress perspective.
Which one should I use and why?
**Edit** : I noticed I get an advantage using `/%post_id%/%postname%` since any mistake etc after `sitename.com/123/wrong-words?some=params&etc=etc` gets redirected to the correct post. But for `sitename.com/123/correct-full-postname/someword` generates a 404. | It makes no difference performance-wise, if it did, there'd be something seriously wrong with WordPress.
The same goes for Google, if a lot of super smart people earning 100k salaries can't write software that handles a trailing slash, then something is terribly wrong with the world.
Either way, WordPress puts the `rel="canonical"` tag in the header so regardless of wether there's a trailing slash or not when you visit the page, Google will see that tag and see what the canonical authoritative URL for that page is.
As a side-note, Google doesn't reserve special rules for WordPress sites, they're all just sites as far as Google is concerned. | stackexchange-wordpress | {

With that URL, WordPress is expecting the value of the `$establecimientos_cpt_name` parameter to be a post slug. Instead you are giving it a taxonomy slug. This will give you a 404 unless you have a post that happens to have the same slug as your taxonomy.

add_action( 'wp_ajax_nopriv_compare_objects_request', 'compare_objects_request' );
Session in 'compare_objects_request' function is not available.
Besides, when in function 'compare_objects_request' putting session_start(), then every time when call is fired, $_SESSION variable is always new set. | WordPress does not use or affect PHP Sessions in any way. Therefore, the session functions will work exactly the same whether you're using WordPress or plain PHP or AJAX requests or anything else.
However, PHP Sessions depend very heavily on your specific PHP configuration. If you don't have the PHP Session settings configured correctly in the PHP.INI, then they tend to not work properly. And a lot of web hosts don't have properly configured defaults for sessions. Therefore, PHP sessions are not safe to use unless you have control over the configuration of the server, and are not suitable for distributed code because a lot of hosts don't have good configurations.
So, make sure you have the setting settings set up correctly in PHP before trying to use them.

Why are so many popular responsive Wordpress themes "boxed" at 940px?
What I mean is that, when the window width is larger than 940px, the main content appears in a box of width 940px, centered in the window, with the area outside the box being a single color or a background image.
The alternative (in a responsive theme) is for the main content to stretch across the entire window width.
I'm curious as to the benefits of either design. When to use one versus the other. | It all has to do with readability, specifically the width of a line of text. Research shows that text can be read faster when a line contains 95 characters per line versus other common line lengths. Couple this with designers' love of small type until the last year or so, and you're stuck with a width-constrained container around the otherwise responsive site. | stackexchange-wordpress | {

How to check if widget has automatic title
Some default widgets has automatic titles.
Is it possible to check if widget has automatic/inserted title using `dynamic_sidebar_params` filter? | Any widgets written to operate as the Core "Recent Posts" widget does can be forced to skip the title by a filter on `widget_title`:

$title = '';
}
return $title;
}
add_filter('widget_title','widget_title_hack_191120', 10, 2);

Clicking On View Post In Draft Opens New Tab
Since 4.0, when you save a post as a Draft the View Post link opens the saved post in a new tab. (target ="_blank")
Is there a way to revert back to the previous behaviour (which was to open the Preview version in the -same- tab?
What's weird is that once the post is published, the saved version opens in the same tab (as in previous WP versions.)
I looked at this post (which seems to be the reverse) Make “Post published. View post” Open in a New Tab

10 => sprintf( __('Post draft updated. <a href="%s">Preview post</a>'), esc_url( add_query_arg( 'preview', 'true', $permalink ) ) ),
to
10 => sprintf( __('Post draft updated. <a href="%s">Preview post</a>'), esc_url( add_query_arg( 'preview', 'false', $permalink ) ) ),
That does what I want. HOWEVER, that's hacking the core. Is there a way to modify this WITHOUT hacking this file?

jQuery(document).ready(function(){

How to develop an extension for a simple form post and post back?
I need to develop a plugin/widget or any kind of extension for WordPress that is a like a static page and is like a Form. In this page I have a form with some input fields that is submitted to server.
By submitting to server I mean I want a piece of code exists that gets Form's data, process it with help of some external web services, get response from that external web services and then creates and send backs response to the page I'm willing to develop.
What should I do? I must go with a special kind of plugins? Any directions?
Please consider I'm not going to use any data or API from WordPress itself.
I'm a ASP.NET MVC developer and have no practice with PHP practically. | I think the easiest way is adding the form via the Shortcode API. The code would look like this:
function myform_handler( $atts ){
if (isset(@$_REQUEST['submit'])) {
//Do something
} else {
$return = '<form action="" method="post">
<input type="text" name="myfield">
<input type="submit" name="submit>
</form>';
}
return $return;
}
add_shortcode( 'myform', 'myform_handler' );
Then you can add on any page the following Shortcode, that creates the form (and the form's response):

Warning: Missing argument 2 for widget_title filter
Based on this question, I'm getting an error `Warning: Missing argument 2 for...`.
This happens for some widgets those are created by plugins.
\-- Edit 1 --
Here's a simple widget that causes the error:
function my_new_widget_register() {
register_widget( 'my_new_widget' );
}
add_action('widgets_init', 'my_new_widget_register');
class my_new_widget extends WP_Widget {
function my_new_widget() {
// Instantiate the parent object
parent::__construct( false, 'my_new_widget' );
}
function widget( $args, $instance ) {
// Widget output
extract( $args );
$title = apply_filters('widget_title', $instance['title']);
echo $before_widget;
echo $title;
echo $after_widget;
}
}
The error is clearly caused by `$title`. | You don’t pass more than argument to that filter, so any callback expecting more than one will not get it. The core calls this filter always like this:
$title = apply_filters(
'widget_title',
empty($instance['title']) ? '' : $instance['title'],
$instance,
$this->id_base
);
But you are passing just `$instance['title']`. Add the missing parameters, and the error will vanish.
If you cannot change the widget, change the registration for the callback for the filter, and make the other arguments optional by setting a default value:
add_filter( 'widget_title', 'my_widget_title_filter', 10, 3 );
function my_widget_title_filter( $title, $instance = [], $id_base = '' ) {
if ( '' === $id_base )

In a shared site, how to get products in a category from one site to another?
Our wordpress site(s) is actually 2 in 1. That is, while they are separate host URLs on the same domain, same server, they run from the same set of wp code, but different databases. They are not multisite because a plugin we need was not compatible. Therefore, we are able to give the appearance of separate related sites, and they run on same wp-content/ but different databases.
We're running woocommerce and want to show a set of products in a category from one site, in the other.
So we have `www.domain.com` and `store.domain.com`. How can we show a category of products in `www` that is configured in `store`?
Thanks in advance, Mike | Since you're not currently running a multi-site install, you can either install the WP-REST-API plugin which is currently in beta, or you can wait for it to hit core which will probably be around version 4.3 or 4.4.
If you were on a multi-site install, you could have easily used the `switch_to_blog()` function to switch between blog databases to query databases.

Post as someone else
I'm starting a blog where multiple people will be "posting". However, most of my authors don't want to have anything to do with the posting process of WP. So they will be sending the articles to someone who would basically do a copy paste and post it, but it has to be as if the author itself did it.
Currently we have to log in as each author and post the content for them. So I would like to know if there's a way to do it from a single account and select a "post as" option and select who you want to post as from a dropdown.
Thanks in advance | If you're logged into WordPress as an administrator, you can easily change the post author of a post to someone else.
So what you'll want to do is set up different user accounts for your different authors and then set yourself up as an administrator. Then when you go to publish a post using your administrator account you can select which author you want it to be published under.

Alter only the page title, not the post titles within
I have a page where, with shortcode, I queried multiple posts from a CPT - so the page is one kind of archive page to the general users.
Page Title
- CPT Post Title #1
- CPT Post Title #2
- CPT Post Title #3
In certain condition I want to alter only the Page Title, not CPT Post Title. I tried:
function wpse_change_page_title( $title ) {
//if( condition matched ) {
return 'Test ' . $title;
//}
}
add_filter( 'the_title', 'wpse_change_page_title' );
But it's altering the CPT Post Titles.
Page Title
- Test CPT Post Title #1
- Test CPT Post Title #2
- Test CPT Post Title #3
How can I alter only the Page title, not those CPT Post Titles?
Test Page Title | I believe that the page title you are talking about is the title from the page from the main query. `the_title()` filter (and `the_content()` filter for that matter) targets all the respective template tags regardless of query.
To avoid this, target only the main query and the specific page.
You can try the following inside your filter
if ( in_the_loop() && is_page( 'specific page' ) ) {
// Do what you need to do
}
## EDIT
I just thought of this, haven't tested it, but you can check your title inside the filter against a known static title and then do something according to that

if ( $title == 'My known title' ) {
// Do something with the title

1. Create a second site. Set the site language to Persian in _Options/General_.
2. Set the language of the first site to English.
3. You can install a plugin to link translated posts like MultilingualPress (disclosure: I was the lead developer for that plugin for a long time).

WordPress Get Header and Footer using in Admin Area
I was wanting a way to get the site header and footer and use it in the admin area.
Idea #1 An answer to another related question states to use an iframe instead I think we can use an ajax call get the header and footer from homepage and store in a function.
Idea #2 Where with jQuery we can clone() them, then store them in a function to use in the admin.
Maybe we need even both, I just think it's possible. I've seen a familiar post but still doesn't answer the question properly.
This is a close start:
add_action( 'in_admin_header', 'insert_header_wpse_51023' );
add_action( 'admin_footer', 'insert_footer_wpse_51023' );
add_filter( 'admin_print_styles', 'footer_hide_wpse_51023' );
function insert_header_wpse_51023()
{
echo '';
}
function insert_footer_wpse_51023()
{
echo '';
} | A very simple experiment...
add_action('admin_init','get_header');
add_action('admin_init','get_footer');
... will demonstrate that the `get_header()` and `get_footer()` functions work on the back end as well as the front, though you will need to adjust for numerous markup problems and other issues.

Enabling shortcodes for custom fields
So, in this post it is explained how to supposedly enable shortcodes for custom fields in Wordpress. (Shortcodes are not enabled for custom fields by default.)
What I dont understand is where to place this code:
<?php echo do_shortcode(get_post_meta(get_the_ID(), 'name', true)); ?>
I understand I have to paste the name of my custom field into the 'name' parameter, but where do I need to place this line of code?
I suppose in the functions.php of the template? I am unsure where though in that file. I don't want to break anything of my template.
Any suggestions are appreciated. | Normally Wordpress does not run shortcode that you put into a custom field.
By default, Custom Fields display whatever value you enter, as plain-text, so if you try entering a shortcode, (in the format [shortcode] VALUE [/shortcode]) you’ll end up displaying the entire text, including the tags.
Add the following in your template file, it can be single.php or page.php:
echo apply_filters('the_content', get_post_meta($post->ID,'YOUR_CUSTOM_FIELD_NAME', true));
or...
$shortcode = get_post_meta($post->ID,'YOUR_CUSTOM_FIELD_NAME',true);

Text with special class as excerpt (or exclude special class)
I am new in Wordpress and I am trying to customize my own theme.
All my posts are starting with a kind of content that I don't want to become the excerpt. It is kind of header.
Is there a way to use as excerpt only content with class `.myOnwnExcerpt`, or maybe it will be easier to ask wordpress to run excerpt rule excluding text with class `.notToBeDisplayedAsExcerpt`. Thanks for any suggestions. | The easiest course of action would be to write manual excerpts instead of having the system generate them.
Second, would be to wrap your "content that isn't an excerpt" in a shortcode. If you look at the `wp_trim_excerpt()` function, which generates excerpts from post content, one of the first thing it does is strip shortcodes. For example, if you had a shortcode like this:
function foocode($atts,$content){
return $content;
}
add_shortcode('foo','foocode');
Anything in the post body such as `[foo]Hello[/foo]` would not appear in the generated excerpts. Note that the "exceprt" is not necessarily the chunk of text that displays on the index page. If the the theme uses `the_content()` the post content will break on the `<!-- more -->` tag, or nothing at all, and your content will still appear. | stackexchange-wordpress | {

switch_to_blog(): Load textdomain
I am using the WordPress multisite feature with Multilingual Press Pro to create a multilingual site with linked posts.
In a network activated plugin the custom post types are registered. For translating the slug I use l10n:
'rewrite' => array(
'slug' => __( 'products', 'text-domain' ) . '/%product-category%',
'with_front' => false
)
This works fine. But, to link to the translated post on another site within the network, `switch_to_blog()` is used. As within this function no plugins are (re-)loaded, my translation files are also not loaded so the permalinks I retrieve will be wrong.
**Is there any possibility to hook into`switch_to_blog()` to load another text domain?**
Thanks! | You could hook into the action `switch_blog`. You get the new blog ID as the first argument here. But loading the complete translation files here is expensive, you also have to restore the old files after that.
WordPress does not use native gettext functions, but some custom code that is much slower. See #17268. The performance penalty for that would be huge.
Filter the URLs from the plugin instead, in this case `mlp_linked_element_link`, and use a hard-coded list of replacements like this:
add_filter( 'mlp_linked_element_link', function( $url, $site_id ) {
if ( 1 === (int) $site_id )
return str_replace( '/produkt/', '/product/', $url );
if ( 2 === (int) $site_id )
return str_replace( '/product/', '/produkt/', $url );
return $url;
}, 10, 2 );

echo '<li><a href="'. get_permalink(). '">' .get_the_title() .'</a></li>';
endwhile;

Embedding Instagram via shortcode doesn't work as advertised in official docs
I am coding up a simple Wordpress theme and I would like to embed Instagram images via shortcode as described on Wordpress.com and Instagram.com. (Both links point to the very pages that demonstrate how this should be working).
So either ` `[instagram url= hidecaption=true width=320]` should be OK to embed an image from Instagram.
However, they don't embed anything. Youtube and Vimeo work fine, but not Instagram. The URL just gets wrapped in a `<p>` tag. The page about oEmbed on Wordpress says, this should be supported since 3.5, I currently have WP 4.0 installed on my localhost.
What am I missing? | The main problem here is WordPress **COM** and **ORG** are **NOT** equal. Questions about support for the former are actually _off-topic_ on WordPress Development.
One consequence of the non-equality of com and org is that the latter has no shortcode `[instagram]`, so naturally it won't work - the built-in shortcodes can be seen at this list. On the other hand, you are right, according to the codex page about embeds Instagram is supported. Normally it works like this:
Instagram photo below
Instagram photo above
It is important that the embeds link is on a separate line.
If that is not working for you, then you can try using the [`[embed]` shortcode](
[embed]
BTW tested the Instagram embed on a old WP 4.0 installation, it works just fine for me. | stackexchange-wordpress | {

My add_action (wp_footer, 'method') is not calling?
In my themes functions.php file I have put:
add_action('wp_footer', 'method');
function method()
{
echo "this is being called";
die();
}
My wordpress footer.php file looks like this:
<?php wp_footer(); ?>
</body>
</html>
What could be the reason my add_action hook is not being called?
I can provide additional code or information if needed.
## EDIT:
Instead of `die()` if I echo a script it won't appear in the pages footer
add_action('wp_footer', 'method');
function method()
{
echo "<script>...</script>";
} | In a WordPress footer hooks are different for back-end(dashboard) and front-end.
In Dashboard use "`admin_footer`" hook.
In Front-end use "`wp_footer`" hook. | stackexchange-wordpress | {

For what security reasons are svgs blocked in the media uploader?
I see that SVGs are blocked by default in the media uploader and you have to add it as a supported MIME type in functions.php. What security reasons are behind this? | SVG can contain JavaScript. JavaScript can be used to hijack cookies or do other questionable actions. It can even be "hidden" in namespaces:
<html xmlns:ø="
<ø:script src="//0x.lv/" />
</html>
_source_
It is very hard to filter that out during the upload, so it is just not allowed by default. | stackexchange-wordpress | {

Category select options for plugin settings
I am using Aqua page builder and I want to incorporate dropdown catagory select field for that.
<?php
$my_options = array ('one' => 'My Pony','two' => 'His Pony');
echo aq_field_select('categories', $block_id, $my_options, $categories);
?>
I have tried `$my_options= get_categories();` But it does not work. The function was basically
function aq_field_select($field_id, $block_id, $options, $selected) {
$options = is_array($options) ? $options : array();
$output = '<select id="'. $block_id .'_'.$field_id.'" name="aq_blocks['.$block_id.']['.$field_id.']">';
foreach($options as $key=>$value) {
$output .= '<option value="'.$key.'" '.selected( $selected, $key, false ).'>'.htmlspecialchars($value).'</option>';
}
$output .= '</select>';
return $output;
}
Thank you . | I think this is what you are looking for .
$cats = get_terms('category');
$blog_cats = array("all" => "All");
foreach ($cats as $cat) {
$blog_cats[$cat->name] = $cat->name;}
Then to show this
<?php echo aq_field_select('category', $block_id, $blog_cats, $category); ?> | stackexchange-wordpress | {

Git Deploying - Disabling plugin/theme installation/update on remote?
Is there any way to disable the installation/updating of plugins in Wordpress?
I am deploying by Github, and therefore changes on server, does not replicate on my development environment.
I need to disable this, and make all updates and installations on my local Git repository, and THEN push to production, with the changes. | Set the constant `DISALLOW_FILE_MODS` to `TRUE` in your `wp-config.php`:
const DISALLOW_FILE_MODS = TRUE;
See the Codex for background information:
> Setting this constant also disables the Plugin and Theme editor (i.e. you don't need to set `DISALLOW_FILE_MODS` and `DISALLOW_FILE_EDIT`, as on its own `DISALLOW_FILE_MODS` will have the same effect).
It will also prevent installing or uninstalling plugins, themes and updating the WordPress core.
This will not affect the Git deployment. | stackexchange-wordpress | {

How do I check if there is a tag in the title
I have many post with multiple tags ex: `AMOS LEE, FOO FIGHTERS,TAYLOR SWIFT`
Post only have one of the tags in the title ex: `“The Man Who Wants You” – Amos Lee`
How would I scan the_title() and go through the tags and store the matching tag in a variable?
Ive tried
<?php
$id = get_the_title();
$posttags = get_the_tags();
if ($posttags) {
foreach($posttags as $tag) {
$tag = $tag->name . '<br>';
}
}
if (stripos($id,$tag) !== false) {
echo 'true<br>';
}else{
echo 'false';
}
?> | Put this in your loop:
<?php
$title = get_the_title();
$posttags = get_the_tags();
if( $title && $posttags ) {
$result = find_tag_in_title( $title, $posttags );
var_dump( $result ); // dump result
}
?>
Put this in your functions.php file:
<?php
function find_tag_in_title( $title, $posttags ) {
foreach( $posttags as $tag ){
if( strpos( strtolower($title), strtolower($tag->name) ) !== false ) return $tag->name;
}
return false;
