Count search results in heading
On my wordpress search page I would like to show a 'total found results'. This needs to be shown at the top of the page in a heading.
I've tried this code but I gives me only the results of the specific page. What I want is all the results, not just the page.
<?php echo $wp_query->post_count; ?> | If you check the documentation for `WP_Query` you will notice that `post_count`, which you are using, returns the number of posts being displayed. That is what you see, but not what you want. `found_posts` returns the total number of results for the query, which _is_ what you want.
> $post_count
> The number of posts being displayed.
>
> $found_posts
> The total number of posts found matching the current query parameters
Note that if your query runs with `'no_found_rows' => true` the `found_posts` value will be 0, and there is a `found_posts` filter that can effect the result as well. | stackexchange-wordpress | {

Can a plugin differentiate syndication feeds from actual site views?
Is there anything in the WordPress API that I can use in a plugin to detect whether the current request to WordPress is a pull of the syndication feed -- as opposed to an actual view of the web-site?
I ask this because it is critical that one specific behavior of the plugin be different for syndication feeds than for actual web-site views. | You can use the template tag `is_feed()` to determine if the current request is for a feed:
if ( is_feed() ) {
// It's a feed!
} else {
// Regular 'ol WordPress
}
Note you'll need to use the function _after_ the request has been parsed (i.e. on or after the `parse_query` hook). | stackexchange-wordpress | {

Overwriting yoast's og:meta output?
I'm working on a blog with hundreds of old posts, and new posts being added daily. I can't change their flow of filling out the yoast meta tag for title. They want the og:title value to be something else though, a custom post_meta value from the same post.
How can I hook into yoast before they grab the title, and say "Don't use the yoast title, instead if we have a custom title filled out, use this one."
If this isn't possible, an alternative option would be to just output a duplicate og:title tag either before or after yoast, so that the yoast tag is ignored. Would I place my tag before or after to wipe out the yoast tag, and would there be a negative impact from having the two tags? | Use the `wpseo_opengraph_title` filter:
function wpse_187763_wpseo_opengraph_title( $title ) {
if ( is_singular() && $post = get_queried_object() ) {
if ( $_title = get_post_meta( $post->ID, 'custom_field_key', true ) )
$title = $_title; // Override title with custom meta title
}
return $title;
}
add_filter( 'wpseo_opengraph_title', 'wpse_187763_wpseo_opengraph_title' );
**Update:** The single `=` is intended, since we're assigning the value & testing the expression at the same time. In other words, it's the same as:
$_title = get_post_meta( $post->ID, 'custom_field_key', true );
if ( $_title )
$title = $_title; | stackexchange-wordpress | {

Upgrading an old Wordpress install to a new one on a new host
I have a Wordpress blog on my server at home, running the latest Debian-maintained version in the 3.x series. I want to try my hand at virtualizing, and I'd like to do it on my blog, using the latest version downloaded from the site. I have read this post, but I want to clarify about different versions.
Is it recommended to upgrade in place (possibly breaking the Wordpress meta-package for Debian) then transfer, or should I transfer, then upgrade? In the latter, would I be able to just directly import a 3.x WP site, or do I need to find the old version, then update it after the data is transferred? | Most of the time any changes that need to be done on upgrade are database related. Core files can be freely swapped pretty much.
WP keeps track of this by comparing `db_version` option (stored in database) against the current value (from core files) on admin load. If there is mismatch it runs the upgrade routine to perform all the necessary changes, until the version is up to current.
In your case the easiest way would probably be:
1. Unpack latest stable WP core at new location
2. Copy old database to new location (or simply reuse old one) and configure new core to see it
3. Copy content folder to new location (configure new core to see it if not placing inside the core folder)
4. New core would pick it up as existing WP site with outdated database and perform the necessary updgrades | stackexchange-wordpress | {

Wordpress tabindex Order
I created a form (through Contact Form 7, although I don't think that makes a difference here), and I believe Wordpress is causing some tabindex issues. I set field 1 to tabindex of 1, field 2 to tabindex 2, etc. Well, when I try to tab from field 1 to 2, it displays a popup in the top left of the screen saying "Skip to toolbar." After researching (not finding a whole lot), I set field 1 to tabindex 3, and went up 1 from there. Well, after tabindex 10 it tabbed to the top of the screen just above the nav. I then came across this page which offers a script that sets the tabindex's very high intentionally. My question is, is that semantically correct or just a work-around? | The "Skip to toolbar" in the WP Navbar comes `tabindex` attribute set to 1; I really think it is correct because it is the first visual element when the navbar is active. The problem is that the HTML of the navbar isn't really the first in the source code, it is in the footer, so your form fields are first in the source code. When two elements has the same `tabindex` attribute, they are navigated in the order they appear in the character stream. So, when you set your fields with tabindex 1 and 2, you go first to your field 1 (it the first in the character stream), then to next `tabindex` 1 element (WP navbar) and then to `tabindex` 2 element (your field 2).
This issue shold not happend when the navbar is inactive.
You can start the `tabindex` of the form fields in 2 or 3, there is nothing wrong with that. The `tabindex` can have any integer value, correlative or not. You can set `tabindex` like `1, 2, 3, 4`; `10, 15, 20, 25` or `84, 12, 98` and all of them are correct. | stackexchange-wordpress | {

How to stop - Database Update Required - from happening again?
So I have had the issue several times now where whenever I update WordPress it gives me the "DataBase update required" and then will not login in to the site. This happens every time I upgrade to the newest version of WordPress.
My fix for this issue is to set the **db_upgraded** field in **wp_option** table in the database and purging the cache.
Fix Database update required
However what I want to know is, how can I stop this happening again? What is happening to bring up this error? Why is WordPress ending up in this loop?

In this version the code change the collation of some tables and this works fine if the change is fast. But in big tables this change take time, hive a timeout in the upgrade process and can't continue, so is a loop.
In your case, the cache data was the reason of the big table size, then you clean the cache, the table is small and you can continue the upgrade. In case you can't "clean" de wp_options table you can replace this file < , has the patch to solve this "loop".

How to Output HTML tags in do_shortcode?
i want to output html tags in do_shortcode(); function
`<?php echo do_shortcode($content); ?>`
is it possible? thx! | Yes it is possible.
There are two ways that I can think of at this moment.
First follow what the codex says Shortcodes. Basically you just wrap your html in ob_start(); this will return the html as a string so you can echo it.
function my_shortcode() {
ob_start();
?> <HTML> <here> ... <?php
return ob_get_clean();
}
The second way is to add your html as a string to a variable then return it later. eg.
function my_shortcode() {
$output = '';
$output.= '<html>content</html>';
return $output;

How to transfer /wordpress folder from one PC to another

Page Template For Custom Post Type doesn't work on URL containing CPT name, other URL's work
Here's a mystery for you. I created a Custom Post Type called "portfolio". Then I wanted a page template to show just those CPT's. It's a custom loop with paging, and it works perfectly if I don't call the page "portfolio" (that is, the permalink) - if I use that, it shows my static home page instead, no loop output. Very odd, since the page I'm using is not the front page.
My first thought is that maybe by using a permalink that matches the CPT name, I'm running into some standard core loop or something.
Or maybe I should just use an archive template instead of using a page template? I was considering the page template so I could have some custom output on the first page, maybe via a custom field.
I am using a cache, but I tried clearing the cache and even disabling it. Same thing.
Any thoughts?

"Edit" option for custom post types archive page

!admin bar | I'm not sure if I understand you correctly, but maybe this will help you.
If you're on CPT archive, then there is no "Edit" link, because it's archive and not a page... Archive is list of posts, so there is no single post to edit... Another example of archive page is when you're viewing search results or all posts from given year - there is nothing to edit in these views.

You can add new page and set its slug to the same value as CPT slug...
Let's say your CPT is 'Book' with slug 'book'. You can add normal page called 'Book' with slug 'book'.
CPT archive and single CPT has higher priority than single page in Rewrite Rules, so this page will be ignored by WP. But you can manually display it's content in `archive-book.php` template... | stackexchange-wordpress | {

How do I add a class to all sidebars to let a Google Custom Search Engine know not to index the content?

How can I lock specific posts (cpt's) from editing by anyone other than ADMINS

Save values generated via API as custom meta fields

How to customize a site hosted on wordpress.com locally

Thanks | WordPress com doesn't allow you to upload any customization, other than CSS via their paid customization feature.
Notably you can _download_ WordPress com themes (link is available in sidebar of theme info page) and use them in self hosted installation.

View WordPress page template usage (or unused)

How is this done please?
WP version is 4.2.2 | What you need to do is compare the values of the meta field `_wp_page_template`, which contains the page template selected for a single page with the available page templates.
For this you need to construct an array of used templates, because you want the templates used by all the pages, similar as shown here:
* Return all custom meta data for one custom post type
Use `array_unique` to get unique values.
Then you need to get the available page templates, as shown here:
* get page templates

Theme twentythirteen widget area clearfix

So, a kind request for help to someone who has maybe dealt with this exact issue already.

min-height: 2000px; // Set this according to the height of the sidebar

#main {
overflow: hidden;
}

How to store the_title() into a variable to reutrn the value, not just echo it

What effect does the_content filter have on performance?
This is general question but lets say I have a function and on a specific page I want to display a table.
The function only applies to one page on my site but every post/page will run this function (and skip it when it 'realises' it isn't the right page).
**Would it be better** , from a performance point of view, **to use a page template** for this specific page **instead of this filter**? Or is this negligible and not worth worrying over.
> Hopefully you get the gist of what I'm asking, I realise there are other factors like how my table (or whatever I'm including) is processed but lets ignore that for the sake of this question.
add_filter('the_content', 'str_load_table');
function str_load_table($content) {
if(is_page('my-table')) {
$my_content = 'pretend this is a table';
$content = $content . $my_content
}
return $content;
} | The difference would be negligible.
The `the_content` filter is fired regardless of whether you use it or not because WordPress uses it for other things. So the only thing that would be performance related would be the complexity of your filter function.
But since you'd probably be doing the same level of complexity in a template or in the filter function, there's no real difference between the two.
I would say that you'd be better using the filter if you want the table to be part of the main content area. Then you don't have to worry as much about how/what styles are applied. | stackexchange-wordpress | {

Insert DIV container below 1st search result

/**
* Inject a Div after the first post on the search page
*/
add_action( 'wpse_before_second_post_in_search', function()
{
echo '<div>My Injected Div</div>';

how could I load a different template part by page

How can I edit submenu headings using wp_nav_menu walker?

'start_in' => $post->ID,
'container' => false,
'items_wrap' => '<div class="page-categories"><ul>%3$s</ul></div>'
));

For the menu item that you want to modify the label of, add the `wpse_menu` class to it:

* We restrict this to the primary menu.

not work. | You want to "reverse" your logic, in a sense. You need "not (home or front)", not "not home and not front". For example:

if ( !(is_home() || is_front_page()) ) {
echo "Hello World";
} else {
echo "Else World";

if ( is_home() || is_front_page() ) {
echo "Else World";
} else {
echo "Hello World";

Wordpress archives in header -necessary?
I just had a look at my source code and found that at the very beginning there's this really long list of archives. I haven't seen this on other blogs:
<link rel="pingback" href=" />
<link rel='archives' title='May 2015' href=' />
<link rel='archives' title='April 2015' href=' />
(.... lots more ...)
<link rel='archives' title='November 2011' href=' />

<link rel="pingback" href="<?php bloginfo('pingback_url'); ?>" />
<?php wp_get_archives('type=monthly&format=link'); ?>

What is the first line doing?
Can I remove both lines from my header?
If I remove it will it have any negative effects (e.g. Google crawling or SEO)?

How does wordpress calculate the page depth?
When using functions such as `wp_list_pages()`, WordPress gives you the `depth` option. How is it calculated?
Is it stored somewhere in the DB? (I couldn't find it).
Or is it calculated in a loop checking post parents?
What's strange is that `wp_list_pages()` offer the parameter `depth` but that function is based of `get_pages()` which doesn't have that same option available. | Ok, lets break it down, all the links are going to be to the source code.
`wp_list_pages()` only uses `get_pages()` to (sic!) get pages, `walk_page_tree()` does the hierarchical structuring inside it. The further course of the process goes `Walker_Page` \- and the generic `Walker` of course -, unless a custom walker is used. Inside `walk_page_tree()` you will see, the walkers `walk` method is called, which subsequently calls the `display_element` method. Mainly in the `display_element`, but also in the `walk`, method you find the handling of the depth.
To make it short: the depth is handled by iterating, `display_element` calls itself until the end or the given `depth` parameter. | stackexchange-wordpress | {

< | Have you tried `is_front_page()`? It should do what you're looking to do.
Unless you've set up front-page.php with the Page Template commented header syntax that identifies the file is a Page Template, I don't think you can use the `is_page_template()` or `get_page_template()` functions.

what is the point of telling add_filter how many parameters you want passed to the function?
In wp-includes/plugin.php (apply_filters) there's this:
foreach( (array) current($wp_filter[$tag]) as $the_ )
if ( !is_null($the_['function']) ){
$args[1] = $value;
$value = call_user_func_array($the_['function'], array_slice($args, 1, (int) $the_['accepted_args']));
}
So if you do 9999 the function will get past more arguments than it needs? How is that a problem? If you don't need the arguments don't put them in the function declaration. Passing more arguments to a function that it's declaration would lead one to believe it accepts doesn't even cause a PHP Notice and is in fact what makes func_get_args() a useful function to use.
Is my reasoning wrong or is there a reason you wouldn't want to tell the function to pass 9999 variables to it? | The reason is that you can register native PHP functions as callbacks. Passing more parameters to them then they expect will raise a warning.
Imagine a filter that can pass 6 parameters and `trim()` as callback. PHP would now raise an error:
> Warning: Wrong parameter count for trim() in …
Some custom callbacks might also change their behavior depending on the amount of passed arguments. That’s surely not good code, but such code exists, and it would break if WP would change its current behavior now. | stackexchange-wordpress | {

Wordpress search seems to look into permalink (which is bad)

When we add an attachment or a local link, into the post content, we normally get the full url, for example:

How do I override the_excerpt so that it will display full content?
I am creating a plugin. Many themes display excerpt such as when `is_search()` is `1`.
I want WordPress to display full content no matter what.
How would I do so?
Should I use `add_filter ('the_excerpt', 'mycontentfunction' );`
Should I use `add_filter` or `apply_filters`? | Following code should do the trick. It takes the excerpt filter and returns the content instead.
function wpse189347_excerpt( $excerpt ){
return get_the_content();

Dashboard memory overload problem
I have a client who has a dev server, and we continue to have problems.
We recently tried to install a new theme, and it's child, and it did become active, but anytime we try to access the dashboard we get this error.
Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 196608 bytes)
There are only 24 active plugins, I have worked hard with the client to reduce the number of actively used plugins.
What else can I do?
I can't even install a caching plugin, without running into these memory errors.
Any suggestions?
Should I use ftp and delete the unused themes? | At the top of your wp-config.php you add `define('WP_MAX_MEMORY_LIMIT', '256M');` this will work only in back-end and do not increase memory in front-end.

Dashboard Widget CSS
I want to add a class name to my custom dashboard widget but I've found no way to do this searching the codex. Right now the only class name on my widget is `postbox` (which is added in '/wp-admin/includes/template.php') but I would like to add more. How can I do this?

Return Value of load_plugin_textdomain
Good Day,
I'm trying to translate my plugin but it doesn't seems to work.
I read that I should check the return value of "load_plugin_textdomain" to see if it's false (meaning it doesn't find my translation file), but I cannot find how to find this value.
Can someone point me in the right direction?
Thanks
_EDIT_ As requested here is the lines to load it
function ap_action_init() {
load_plugin_textdomain('my_plugin', false, WP_PLUGIN_DIR . '/languages' );
}
// Localization
// Add Actions
add_action('init', 'ap_action_init'); | global $langOK;
add_action( 'plugins_loaded', 'myplugin_load_textdomain' );
function myplugin_load_textdomain() {
global $langOK;
$langOK = load_plugin_textdomain( 'my-plugin', false, dirname( plugin_basename( __FILE__ ) ) . '/languages' );
}

Wordpress Plugin manipulate have_posts()
I want to develop a plugin, which changes the post order on the blog page, I think I need to manipulate the `have_posts()` function. How can I do this? | The standard query for posts uses `orderby => 'post_date'` and `order => 'DESC'`. The best candidate for arbitrary sort of posts would be `orderby => 'menu_order'` and `order => 'ASC'`. The `menu_order` is not generally used for posts but it is safe to be used. As suggested by Pieter Goosen use action hook `pre_get_posts`:
add_action( 'pre_get_posts', 'your_function_name' );
function your_function_name( $query ) {
if ( !is_admin() && is_home() && $query->is_main_query() ) {
$query->set( 'orderby', 'menu_order' );
$query->set( 'order', 'ASC' );
}
}
The above is for front end. For back end use visual drag and sort jquery and update the database. You can check the logic in pageMash plugin. | stackexchange-wordpress | {

Two questions about CSSing inside the menus
First, I would be glad if u tell me how can I assign a class(css) to default span tag that include the links inside the menu, created by WP control panel.
And second question is how to use @media queries to define different style of links inside a menus? If I'm using an image instead of the text in the menu, how can I apply different img for another resolution? Say, I got IMG_1 for higher than 999px width screen and IMG_2 for less than 999px screen. I definitely can't just img url from css... so how to make it work? I don't want to use background image as for link, it's ugly :/
Thanks!
UPDATE: Okay, so I think I answered my self the second question. I used span(in order not to go with div inside the span-the default tag comes with WP :/ ) as inline block element, and assign width and height to it, and use background image in the css. This way I can sure to make it with hover effect and also use proper @meta. | If you want your navigation span element to be a block, instead of inline element, just target it via css
nav > ul > li > a > span{
display:block;
}
This is providing your HTML structure looks something like this:
<nav>
<ul>
<li>
<a href="#" class="menu-link">
<span>Home</span>
</a>
</li>
<!-- other list elements go here -->
</ul>
</nav>

Possibility of Create Site Specific CSS in a Multisite
I would like to know that using multisite feature, is it possible to have exactly same multiple wordpress sites, same content, same themes, (each on its own subdomain) but having few css styles specific to each site?
If so, then how can we achieve this. | Yes, you can add website specific class to BODY, for example.
Best approach is to create little multisite enabled plugin, that adds some class to BODY in `body_class` filter.
function customBodyClass( $classes ) {
global $current_blog;
$classes[] = 'website-'.$current_blog->blog_id;
return $classes;
}
add_filter( 'body_class', 'customBodyClass' );
All themes has to use `body_class()` function in BODY tag, obviously. | stackexchange-wordpress | {

Custom Posts Types using Posts Category

array(
'labels' => array(
'name' => __( 'Cupons' ),
'singular_name' => __( 'Cupom' )
),
'public' => true,
)
);
} | The documentation for `register_post_type` mentions a `taxonomies` parameter, giving it a value of `array( 'category' )` will do what you want.

I created a custom form in HTML/CSS and now I need it to submit ... should I create custom PHP or is there a plugin I can use?
I'm new to WordPress development and any advice would be appreciated! I have been a front-end developer for a while and have always handed off forms I created to a back end guy or gal for them to create the functionality via PHP. My knowledge of PHP is extremely lacking.
Anywho what I'd like to do is take all the info the user checked off or typed etc, and send it... (you know, like forms do) but since I created this custom form that I designed and coded in HTML and CSS, is it too late to apply a plugin? Basically, I'm wondering if since it's all already coded do I have to code the PHP myself or can I pull FUNCTIONALITY ONLY from a form plugin? | The full answer is that you could code it by hand or use a plugin. :)
Many form plugins, however, generate loads of HTML and CSS already, and due to the fact that styling forms is a huge pain (even for a CSS geek like me), you'd be writing tons of CSS overrides to overcome the aggressive coding of, say, Gravity Forms or the like. I spent a huge amount of time re-styling a Gravity Form, and probably used some foul language while doing so (that was just CSS, not HTML changes).
If I were doing this, I'd use Contact Form 7, which allows you to stick all your HTML in its admin screen for each form. You would have to learn the way to define fields in Contact Form 7, which is not hard IMO - it's way easier than raw PHP. Take a peek here and see if it looks easy or hard. And you'd still need some add'l CSS to work with Contact Form 7's CSS, but maybe not too bad.
Then again, someone may chime in with an easy way to hand-code the whole thing. Not my cup of tea, though. :)

Removing non native customizer settings from a child theme
For removing settings, controls and sections of the customizer, we can just simply use the remove methods like this:
function remove_custom($wp_customize) {
$wp_customize->remove_setting('id');
$wp_customize->remove_control('id');
$wp_customize->remove_section('id');
}
What I notice is that there's no way to remove parent-theme customization, so non native customization of Wordpress itself. In fact, trying to remove the `blogdescription` is possible.
I can't find documentation about that. What am I ignoring? | I am guessing a lot about how your themes work but, the child theme's `functions.php` runs _before_ the parent theme's `functions.php`, so anything loaded by the parent's functions isn't going to be present for you to remove. You need to hook your function so that it runs later.
add_action('after_setup_theme', 'remove_custom');
Though you would need to mess about with the `$wp_customize` variable. It would be easier to hook into the `customize_register` hook with a high priority number so that your code runs after the parent registration code.

What exactly does the 's' parameter search for in WP queries?
I have a simple question, but can't find the answer anywhere. What exactly does the 's' parameter search when used in a query? Ex:
`$args = array( 's' => $keyword ); $query = new WP_Query($args);`
Does it just search post content, or does it also look at title, tags, etc?
**EDIT:** Just to clarify. The question is what post fields are being searched, not what data is being returned. | As usual it's most reliable to dump the resulting SQL query and see:
SELECT wp_posts.ID
FROM wp_posts
WHERE 1=1
AND (((wp_posts.post_title LIKE '%keyword%')
OR (wp_posts.post_content LIKE '%keyword%')))
AND wp_posts.post_type = 'post'
AND ((wp_posts.post_status = 'publish'))
ORDER BY wp_posts.post_date DESC LIMIT 0,5

How Do I get the author's page id?

I have already tried functions like: `url_to_postid()` and `get_page_by_path()` with no success.
I am using a custom permalink structure for author pages: `
Is there a way I can accomplish this? | It sounds like you need `get_author_posts_url()` which "Gets the URL of the author page for the author with a given ID." If you have set the custom permalink correctly it should work.
If you really are looking for actual page IDs, **_there is no page ID for an author archive page_**. Those pages are dynamically generated and are not "posts", "pages", or any other post type. They are not built to support comments. You are going to have to cook up your own system for that. | stackexchange-wordpress | {

Is it possible to create a contact form without using a plugin?

Display custom fields only if it has a value
I've setup standard custom fields for some products in WooCommerce which are being displayed on each product page on the front end. However, I'd like to hide those fields that don't have a value entered. I've tried some suggestions made elsewhere on this site but they didn't work for me.

<div id="customfield-meta">
<?php
// Display Custom Field Value

echo "<li>Height (px): ".get_post_meta( $post->ID, 'isheight', true )."</li>";
echo "</ul>";
?>
</div> <!-- end #customfield-meta -->
Any ideas how I could do this? Thank you | You can use isset() function to check if it has a value.
In your case you can do like this :
$width = get_post_meta( $post->ID, 'iswidth', true );
if( isset( $width ) ){

How to run Jetpack from localhost?

Is there any way to work around this running on localhost? | Add this to your `wp-config.php`:
const JETPACK_DEV_DEBUG = TRUE;
This makes it possible to use features on localhost that don’t require a connection to wordpress.com. See the announcement post on jetpack.me for the background.
For your own plugins, learn that lesson: Do not rely on working outgoing connections. Respect your users privacy, and explain in clear words why such a connection is necessary, what data will be sent, and how to work with the plugin when the connection fails.

Missing Jetpack Contact Form button when running locally

It's running fine, however after activating Contact Form, the button is not appearing when creating/editing a page.

And lastly, tried switching themes, was using 2015 then tried 2014 and 2013 and the button still doesn't appear.

How it should be: right display
NOTE: its not online visible, because of debugging services | It seems to be missing the opening `<?php` or else that text shouldn't be readable above the image. The file seems to be using index.php but it's possible depending on your theme setup that it's a different file missing the `<?php`.
