What's wrong with my use of plugin_url()?
I keep getting the following message in the browser `Fatal error: Call to undefined function plugin_url() in`
My code at present:
add_action( 'wp_enqueue_script', 'load_jquery2' );
function load_jquery2() {
wp_enqueue_script( 'jquery' ); }
function add_my_css_and_my_js_files(){
wp_enqueue_script('jquery-validate-min', plugin_url('/activate/jquery_validate_min.js', __FILE__ ) );
}
add_action('wp_enqueue_scripts', "add_my_css_and_my_js_files");
The plugin is in a folder called 'activate' & the JS is in that folder directly, not a sub folder. | function add_my_css_and_my_js_files(){
wp_enqueue_script('jquery-validate-min', plugins_url('activate/jquery_validate_min.js', __FILE__ ) );
}
add_action('wp_enqueue_scripts', "add_my_css_and_my_js_files");
1. You need to use the `plugins_url()` function (you are missing the **s** at the end of _plugins_ ).
2. Reference the location of the script file with the relative path. Meaning the path should be `activate/jquery_validate_min.js`. | stackexchange-wordpress | {

Problem with multiple menus in theme
I am having trouble trying to get my new theme working. I have all 4 menus working on my test server but when I move the theme to the live server and set up all but one (main-menu) will not show up.
Here is my code for the menus:
register_nav_menus( array(
'main-menu' => __( 'Main Menu', 'Bootstrap WP Primary' ),
'second-menu' => __( 'Second Menu' ),
'footer-menu' => __( 'Footer Menu' ),
'mobile-menu' => __( 'Mobile Menu', 'Mobile Menu' )
));
Here is the code from the current template:
register_nav_menus(
array(
'main-nav' => __( 'Main Nav' ),
));
Is it a conflict with the main menu items?
!white Menu is Second Menu, Purple is Main !white Menu is Second Menu, Purple is Main and isn't showing up on live site
Also upon inspection of the code the menu isn't even being populated on to the page. | To display a menu you need to use the `wp_nav_menu` function (Codex reference).
Try changing your template file to use the following code:

Activating a Theme Options page to Editor - not working
I used Ian Stewart's Simple WordPress Theme Options Page (Source^) for my client's site, where I assigned my client as an Editor. But from the Editor account the **Theme Options** link is not visible.
I checked the `theme-options.php` for `add_theme_page()`, where it's used `'edit_theme_options'` as the menu's capability. But unfortunately it's not visible. I installed:
* User Role Editor, and
* White Label CMS
But in White Label CMS, I unchecked the hide menu thing. But the link becomes visible only if I check the User Role Editor's `manage_options` checkbox. But it opens the Settings menu to the Editor. I checked the `edit_theme_options` for Editor, but it doesn't work.
I changed the `theme-options.php`'s `add_theme_page()` capability to even lower to `edit_published_posts` (Author capability), but not worked here. I tried deactivating User Role Editor, but no luck. | Ok. Found the guilty one: it's **White Label CMS**. !White Label CMS

Create a wordpress admin user and only let them edit and post blog posts?

How can I safely delete data related to wp_post table manually from the mysql database?
Recently I downloaded a plugin that had a bug that orphaned its custom post type items in the wp_post table rather than deleting them. Being new to wordpress, it wasn't apparent to me that the wp_postmeta table was related to that table. Now, I have entries in the latter with NULL values for the $post_id. (I simply deleted everything in wp_post with that content type.)
I'm assuming that it would be easy enough to do a left join query to find all those wp_postmeta items and delete everything with $post_id NULL. But, I'm not exactly sure how the wordpress tables relate to each other. If I were to do this manually, are there any other default tables that need to be taken into consideration? Does anyone have a script in their library to handle something like this?
If you can suggest a plugin, I'm open to that as well. | As you already deleted all the posts in the table, this is going to be quite a bit of work manually.
For the next time you do something like that, use `wp_delete_post( $postid, $force_delete );` (Codex) while looping through all the posts with that posttype, as this function deletes all the data associated with that post.
$args = array(
'posttype' => 'yourposttype',
'numberposts' => -1
);
$todelete = get_posts( $args );
foreach( $todelete as $deletethis ) {
wp_delete_post( $deletethis->ID, true );
}
In your case, you will have to check the following tables for data (I skip the tableprefix here):
* posts (which you already did)
* postmeta
* comments/commentmeta
* term_relationships
In all cases you will have to search for entries with the `post_id`/`object_id` NULL or with no entry in the posts table, and delete them. The SQL should be pretty straight forward. | stackexchange-wordpress | {

how redirect users to custom login page when "login to reply" is clicked?

Custom category for posts via XMLRPC
I have a blog located at one site that when I post into a category, it will auto-post via XMLRPC to another site of mine. This functionality works, but I would like to assign a category to these posts.
Is there any way to do this? The only site that will be posting this way is controlled by me, so I don't care if it's global.
Thanks | You can do it by sending the 5th parameter to wp.newPost, like this:
$request = xmlrpc_encode_request( "wp.newPost", array( 1, $xmlrpc_username, $xmlrpc_password, $content, $terms) );

Make WooCommerce pages accessible for logged in users only

It works fine on my local server but when I upload it to the live server, the meta box doesn't appear.
Its does however appear in the screen options, so I know the code is working to some extent but it's just not displaying anything on the edit page.
I've uninstalled all the plugins and that didn't equally solve the issue.
Below is my code:
function ila_add_custom_box() {
add_meta_box(
'content-on-page',
'Content On Page',
'ila_render_meta_box',
'page',
'high'
);
}
add_action( 'add_meta_boxes', 'ila_add_custom_box' );
function ila_render_meta_box() {
echo "<h1>Edit Page Options</h1>";
}
How can I resolve it? | You missed one argument in the `$args` for `add_meta_box`.
The correct use would be (Codex):
add_meta_box( $id, $title, $callback, $post_type, $context, $priority, $callback_args );
You forgot to set the `context`, add it and you should be fine.
add_meta_box(
'content-on-page',
'Content On Page',
'ila_render_meta_box',
'page',
'normal', // add this line
'high'

How do I get resized thumbnails?
I'm getting post thumbnails by calling `the_post_thumbnail(array(400,300), true);` However, this displays the fullsize featured image, just resized with the html "height" and "width" tags. This is not good for loading times. I've tried regenerating thumbnails and that doesn't make a difference.
Isn't there a way to get thumbnails that have been resized? | Your example code is calling the full size image as you mention and resizing to the dimensions you feed into the array.
I've answered this question before here, but the basic idea is that you'll want to use `add_image_size()` in your `functions.php` to tell Wordpress you'd like it to create a new image size when you upload images.
Then you'll need to use `wp_get_attachment_image()` to call the image into your template. | stackexchange-wordpress | {

WP E-commerce and Display Fancy Purchase Notifications

How to change src link in YouTube?
I want to add `html5=1` in YouTube link. How can I do that? I try something like this:
function add_embed_filter($html, $url, $attr) {
$new = str_replace('oembed', 'oembed&html5=1', $html);
return $new;
}
add_filter( 'embed_oembed_html', 'add_embed_filter', 50, 3 );
but in source it look like this: `?feature=oembed&html5=1` :/ | function add_embed_filter($html) {
return '<div class="js-video widescreen">'.str_replace("?feature=oembed", "?html5=1", $html).'</div>';
}
add_filter( 'embed_oembed_html', 'add_embed_filter', 50, 1);
Of course if WordPress or Youtube change how this url is constructed you will have to adapt your code accordingly, but I tested it, and this will get you there with WordPress 3.8.1. I also did not test how this works for a user who does not support HTML5 and depending on your use case, you may wish to test to ensure that this code will support them. | stackexchange-wordpress | {

How to redirect non-logged in users to a specific page?
How to redirect non-logged users requesting for a specific page/URL to another page/URL and display a message like "for members only". I know its quite easy to code using !is_user_logged_in() function but i don't know how to code it because i am a newbie to WordPress. Care to tell me the file to put the code also. | Here are 2 examples which you will need to modify slightly to get it working for your specific needs.
add_action( 'admin_init', 'redirect_non_logged_users_to_specific_page' );
function redirect_non_logged_users_to_specific_page() {
if ( !is_user_logged_in() && is_page('add page slug or ID here') && $_SERVER['PHP_SELF'] != '/wp-admin/admin-ajax.php' ) {
wp_redirect( ' );
exit;
}
}
Put this in your child theme functions file, change the page ID or slug and the redirect url.
You could also use code like this:
add_action( 'template_redirect', 'redirect_to_specific_page' );
function redirect_to_specific_page() {
if ( is_page('slug') && ! is_user_logged_in() ) {
wp_redirect( ' 301 );
exit;
}
}
You can add the message directly to the page or if you want to display the message for all non logged in users, add it to the code.

How to enable qTranslate languages tabs in custom plugin page
For example, I have created a custom post creator. I am using `wp_editor()` to generate "WYSIWYG" editors for content.
I am using `qTranslate` for multi-language user experience. Unfortunately I am forced to create a separate "WYSIWYG" editor for every language translation. Overkill.
How to enable / implement `qTranslate` language tabs as they are in default post creator. | 1 - I would think that the qtranslate plugin will add the tabs to the wp_editor() editor automatically. At least , it was doing it when I used it for CPT ..
2 - there is this plugin which helps plugin authors to implement qtranslate in own plugins .
3 - there is a filter `add_filter(‘the_editor’, ‘qtrans_modifyRichEditor’);` in qtranslate you might want to investigate
4 - you can also use a simple loop in order to create the tabs using `qtrans_getLanguage()` | stackexchange-wordpress | {

Is there any hook for theme activation ? or something similar?
I know this has been asked before however my question is different.
So. I have a plugin that creates custom post types on the fly. the plugin also has a function to create template files for each of those custom post types.
it simply goes to those theme folder and create template page for each of the current theme. this works perfectly for the current themes. however what happened if the admin added another theme and active it ?
So i am looking for a way to detect activation and then run the function to create the template page for that theme.
My first idea was to check theme activation hook which i dont think going to work.
Anyone with a different idea ? | Don't save the template in the current theme.
Instead, save the template in your plugin itself and try to use the template using `template_include` filter for particular page or whatever using `is_page`.

Translate placeholder text in search field
I want to translate the placeholder attribute in my search box. I am using the WPML-plugin to translate all text. How can I accomplish this?
My code:
<input type="search" class="search-field" placeholder="Your Search term here" value="<?php echo esc_attr( $search ); ?>" name="search"> | Just as any regular string, you can use
<?php esc_attr_e( 'Your Search term here', 'your_theme_slug' ); ?>

esc_attr_e( 'Your Search term here', 'your_theme_slug' );
?>" value="<?php
echo esc_attr( $search );
?>" name="s">
WPML, as well as WordPress, uses the PHP `get_text()` function. You can translate this either with the additional String Translation Plugin, or you create a mo/po file for your theme. | stackexchange-wordpress | {

How to place HTML below the title of the (custom) post overview
**Edit:** Yes, I know, I provided an answer to this question myself. However, I'm still interested in other solutions and/or comments on the one I found. Is this how you would do this? Are there any other ways?
* * *
I would like to provide some additional description and on-page help (i.e., no contextual help or help tabs) on the overview page (i.e., `edit.php`) for a custom post type.
According to `edit.php` (as well as `class-wp-list-table.php` and `class-wp-posts-list-table.php`) there is no appropriate hook.
So, how can I do this?
A few notes:
* I came up with a solution, which I would describe _a bit hackish_ , so I'm open for a _clean_ solution (if there is one);
* I will post my solution as an answer so you can comment on that (and so the question and answer are kept separate);
* I'm aware that I can do this via JavaScript/jQuery - but that's not _clean_ (IMO) as well... | I kind of feel like I'm missing something obvious, but maybe I'm not. What about the `admin_notices` hook, seems like the obvious choice to me.

using nav menu id's

Reading in the codex, I should be able to use page_id. When I refresh the page, I do not get any posts or pages. Having tried many different versions of this query, this is where I am at right now.
$page_query = new WP_Query( array('post_type' => array( 'post', 'page'), 'page_id' => array($number))); | If you have posts and pages then `page_id` isn't the correct parameter. You should probably use `post__in`. See `WP_Query Parameters`.
Additionally, `post__in` accepts an array, whereas you have a string, so you'll need to use PHP to `explode` the string into an array.
This is untested, but I think it should do it:
$ids = '7,43,20,22,16,1051,18,26,9,24,28,10523';
$ids = explode(",", $ids);
$page_query = new WP_Query( 'post__in' => $ids, 'nopaging' => true );

Removing WordPress version number from included files
I am trying to remove the WordPress version number from the file extensions for security purposes. Some of the enqueued files include the WordPress version number on the end of them, which can be seen from the inspector. For example:
`<link rel="stylesheet" id="admin-bar-css" href=" type="text/css" media="all">`

Creating two loops based on different logic
I'm trying to figure out the best way to go about this and I have part of my solution, but I can't figure out all of it.
My ultimate goal is within a certain page template, to show the newest post from a CPT of a particular taxonomy, this seems to be the easiest and accomplished with this:
$args=array(
'post_type' => 'portfolio',
'post_status' => 'publish',
'orderby' => 'date',
'order' => 'DESC',
'posts_per_page' => 1,
'type' => 'featured'
);
$portfolio_query = new WP_Query($args);
The next part would be show all of other posts, with the exception of the post that is queried above.
Can this be done with a single loop, or will I need multiple loops with offset logic? I'm lost on how to accomplish this. TIA. | This will most likely require two loops to the best of my knowledge. The second loop just needs to know to exclude the post you just queried. Something like the following should do the trick.
$first_id = 5; // This should be set in the previous loop to the post ID of the post returned by your first query.
$args2 = array(
'post_type' => 'portfolio',
'post_status' => 'publish',
'orderby' => 'date',
'order' => 'DESC',
'posts_per_page' => 10,
'type' => 'featured',
'post__not_in' => array( $first_id ),
);
$portfolio_query_2 = new WP_Query( $args2 );

Accidentally messed up URLs
So I installed WordPress on my Apache server and I changed the URL in the WordPress Admin Control Panel to ` from ` and now it's taking me to my old `index.html` I made before I installed WordPress, even though I moved all my old stuff to a backup folder. Now I cannot get back into my WordPress admin CP.
So my question is:
How do I switch the URLs inside the WordPress files instead of the Admin CP (Cause I cannot get to it).
How do I make the WordPress url to ` instead of `
P.S. I didn't include http:// on the links because I can't post more than two links with my rep. | Codex has an article on Changing The Site URL, you can edit values in database or override them in config.

Post attachments doesn't show after manual db import

Themes VS Plugins
If I am customizing a WordPress site, should I do that via a theme or a plugin? By customization I mean:
1. Add new custom post type
2. Add new fields to the Users
3. Add new widgets
4. Add custom permalinks
I am leaning to creating new plugins for the above, and leave the theme for styling, however I wanted to confirm if this is the right approach.
Thanks. | Yes, the types of customizations you are enumerating are _persistent_ to the site, regardless of theme changes. They are indeed commonly recommended to be contained in a plugin.
Personally I consider there is exception from the rule when theme is uniquely developed to the site and de-facto _is_ site project. However I am tad in minority about it and most people insist on plugin approach even in that case. | stackexchange-wordpress | {

Multiple WordPress on Virtual Host
I have AWS EC2 Linux server. Currently only one wordpress multisite mode is hosted in root folder (/var/www/html).
Now I would like to host another wordpress site. So that I have enable apache virtual host.
Here is my vhost.conf
NameVirtualHost *
<VirtualHost *>
ServerName firstdomain.com
ServerAlias www.firstdomain.com
DocumentRoot /var/www/html
</VirtualHost>
<VirtualHost *>
ServerName seconddomain.com
ServerAlias www.seconddomain.com
DocumentRoot /var/www/html/seconddomain.com
</VirtualHost>
I have one php test file inside seconddomain.com folder and I can browse by www.seconddomain.com
After that I download wordpress and copy into seconddomain.com folder and change the wp-config.php.
But I got the error "This webpage has a redirect loop".
Is it because I have one wordpress in root folder or other security reason?
Regards, Alex | Thanks for comments.
I can manage to host two separate WordPress site on VirtualHost EC2 Linux AMI.
My mistake is I have created the vhost.conf file in under /etc/httpd/conf.d.
Correct way to enable VirtualHost on EC2 Linux AMI is as follow :
1. go to /etc/httpd/conf
2. open httpd.conf file
3. go to end of file
4. uncomment NameVirtualHost *:80 line
5. add the virtual host

Hide mu-plugins list
I'm using mu-plugins, <
These plugins are showing in plugins.php, <
Is there any way to hide it?
Thanks. | The solution to this request is filtering `show_advanced_plugins`. This filter is called twice, once for `mustuse`\- and once for `dropins`-plugins.
The filter accepts two parameters, the first one being the standard value (`true`), and the second one being the type of the advanced plugin (Must-Use and Drop-In).
So returning false does the trick, if your condition is met. If you want Dropt-Ins to be hidden as well, just set the function to `return false`.
Please be aware that a Plugin can alter this filter, so you may have to change the priority to achieve the desired results (3rd parameter). Also return the `$default` value in the standard case, to allow other functions the same functionality.
And here comes the code:
add_filter( 'show_advanced_plugins', 'f711_hide_advanced_plugins', 10, 2 );
function f711_hide_advanced_plugins( $default, $type ) {
if ( $type == 'mustuse' ) return false; // Hide Must-Use

Order Custom post type loop by custom field (datepicker)
I know there are a lot of articles and documentation on this but I can't seem to figure it out.
I have a custom post type 'agenda' wich is made for events. I want to sort this by the eventdate. For this, I made a custom field (datepicker) using the ACF plugin.
I've found some documentation on the ACF website wich learned me how to echo the date in dutch format and also an article about sorting the posts by custom meta value. But I can't get it to work.
The key for my custom field is: datum_agenda
Codes I have already tried ( in the $args of the loop):
'orderby' => 'datum_agenda'
&
'meta_key' => 'datum_agenda',
'orderby' => 'meta_value_num',
'order' => 'DESC'
What am I doing wrong here? Seems like my code can't seem to find my meta_key or something because it still sorts by the autovalue.. (the normal post date) | Your second approach should in my mind actually work, you do it like this:
**Code:**
$args = array(
'post_type' => 'agenda',
'posts_per_page' => -1,
'meta_key' => 'datum_agenda',
'orderby' => 'meta_value_num',
'order' => 'ASC'
);
$my_query = new WP_Query( $args );
There are two pages at the ACF documentation you might want to read: Date Picker and Order posts by custom fields. Besides that the only thing that comes to mind would be _how is the date formated_ and might the problem originate there, having `yymmdd` as value for the ACF »Date Picker« field »Save format« is recommended. | stackexchange-wordpress | {

Why write markup for index.php?
As I understand, index.php (a required template) is used when a more specific template is unavailable---according to the template hierarchy.
My question is, if I create all the specific templates that my theme uses (e.g., home.php, single.php, page.php, search.php, archive.php, 404.php, etc...), then why bother writing any markup in index.php at all? I might as well just leave it blank? Is there a reason to fill out index.php? | WordPress might extend the existing template hierarchy in a future version. Your users would get a blank page after an upgrade. So write at least the basic loop, header, footer and pagination.
Another point: I use and see at the `index.php` usually as _the default template_. I treat its layout as the core concept and all other templates as specialized variations.

`if( $values || $values !== ' )...`
Alternately, your field may be returning an empty array or some other kind of "unechoable" value.
Try putting `var_dump( $values )` after you set the `$values` variable and see what you're working with. Then adjust your `if()` statement to account for other possible non-empty values you may want to weed out before outputting a link.

Also, you shouldn't use `the_field()` in an echo statement since the_field already echos its output. Change this:

how to redirect to url.com/wp-admin if url.com/admin is typed in?
How would I create a wordpress function that will redirect a user to myurl.com/wp-admin if they type in myurl.com/admin?

if ( 'admin' === $request )
{

How can i retrieve all custom registered taxonomy?

wordpress post not showing my "<somehting>" text>?
I am trying to make a post where there is a text line :
> some libraries to run which we will import by using "`#include <filename.h>`" command.
instead of outputting the text as it is. It shows as:
> some libraries to run which we will import by using “#include ” command.
in post so `<filename.h>` is missing for some reason. I am quite sure I am missing something here but unable to find. I think for some reason WordPress escapes anything between <> tags so how can i show them if i need to? | You have to escape th `<` and the `>` with `<` and `>`, otherwise WordPress will remove the “unknown tags”.

// find and escape < and > on specific positions, then

Custom Same Page Search
I've added a custom form to one of my page templates. It submits to itself `$_SERVER['REQUEST_URI']` in hopes I can grab the `$_GET` values and modify my query using `pre_get_posts`, but instead it goes to 404.
So to clarify, I don't want to use search.php, I want it to post back to my page template and modify my query to show the "filterd" results instead of 404ing.
I've tried using `pre_get_posts` to test if it's 404 or search, but I also don't want to stop anything else from 404ing.
So how can I use a query on the same page / url / page template without needing to reply on `search.php` or having my query cause a 404?
So with the custom search form in place the url is currently ` \- and I want to modify the query on the specific page depending on the `$_GET` value. | Don't use a query variable that is used by the WordPress Core. That is, none of these.

How can I specify that an area of my theme contains widgets?

You also mentioned a image slider.
You can conditionally load the slider so it only displays where you want like the front page only.
An example would be to add this code in your header.php file so the slider only loads on the front page.
<?php if (function_exists('slider_template_tag') && is_front_page()) { slider_template_tag('82'); }?>
You can do the same with the widgets.
<?php if ( is_active_sidebar( 'left-sidebar' ) && is_page('007') ) : ?>
<ul id="sidebar">
<?php dynamic_sidebar( 'left-sidebar' ); ?>
</ul>
<?php endif; ?>

How to import CSV into Custom Post Type custom fields?

Wordpress MAMP Installation Issue

flush_rewrite_rules() cancels the effect of add_rewrite_rule()
As one of my plugin's features, I'm trying to define a custom url structure, like ` I'm using `add_rewrite_rule()` along with `flush_rewrite_rules()` on plugin activation, which works as expected.
Until `flush_rewrite_rules()` gets called again, during another request, either by hand or by enabling another plugin that does so. When this happens, my rewrite rule suddenly disappears (I'm using Rewrite Rules Inspector to check this).
The minimum code needed to reproduce the issue is this:
<?php
/*
Plugin Name: PluginA
*/
register_activation_hook(__FILE__,'PluginA_activation');
function PluginA_activation()
{
add_rewrite_tag('%foo%','([^&]+)');
add_rewrite_rule('foo/([^/]+)','index.php?foo=$matches[1]','top');
flush_rewrite_rules();
}
Any idea what I'm doing wrong? | Rewrite rules are stored in an option. When `flush_rewrite_rules()` is called, this option is removed, WordPress collects all rules registered during the _current request_ and writes that option new into the database.
You registration doesn’t run on every request, so it doesn’t exist, when the option is rewritten.
Register the rule on ever page load, flush the rewrite rules on activation. Separate the registration and the flush.
register_activation_hook(__FILE__,'PluginA_activation');
add_action( 'wp_loaded', 'PluginA_rewrite_rules' );

{

Block wordpress style for my plugin admin page

You cannot disable just a part of it.
If you want to apply your own rules, use a higher specificity in your CSS rules. Normally, all plugin pages use the same wrapper element:
<div class="wrap">
<!-- page content here -->
</div>
You can add an `id` attribute here …
<div class="wrap" id="unique_plugin_prefix">
