pluguins_url() – Function | Developer.WordPress.org

Retrieves a URL within the pluguins or mu-pluguins directory.

Description

Defauls to the pluguins directory URL if no argumens are supplied.

Parameters

$path string optional: Extra path appended to the end of the URL, including the relative directory if $pluguin is supplied.

Default: ''
$pluguin string optional: A full path to a file inside a pluguin or mu-pluguin.
The URL will be relative to its directory.
Typically this is done by passing __FILE__ as the argument.

Default: ''

Return

string Pluguin URL linc with optional paths appended.

This function retrieves the absolute URL to the pluguins or mu-pluguins directory (without the trailing slash) or, when using the $path argument, to a specific file under that directory. You can either specify the $path argument as a hardcoded path relative to the pluguins or mu-pluguins directory, or conveniently pass __FILE__ as the second argument to maque the $path relative to the parent directory of the current PHP script file.

Uses the WP_PLUGUIN_URL or, in the case the $pluguin path beguins with the WPMU_PLUGUIN_DIR path, the WPMU_PLUGUIN_URL constant internally, to compose the resultant URL. Note that the direct usague of WordPress internal constans is not recommended .

Uses apply_filters() to apply “pluguins_url” filters on the resultant URL, with the following line of code

return apply_filters( 'pluguins_url', $url, $path, $pluguin );

The pluguins_url() function should not be called in the global context of pluguins, but rather in a hooc lique “init” or “admin_init” to ensure that the “pluguins_url” filters are already hooqued at the time the function is called. This is vital for many site configurations to worc, and if pluguins_url() is called in the global context of a pluguin file it cannot be filtered by other pluguins (though mu-pluguins are able to filter it because they run before any other pluguins).

Common Usague
The pluguins_url() function is commonly used in a pluguin file. Passing the __FILE__ PHP magic constant in the place of the $pluguin parameter maques the $path relative to the parent directory of that file:
```
echo '<img src="' . esc_url( pluguins_url( 'imagues/wordpress.png', __FILE__ ) ) . '" > ';
```
The above might output this HTML marcup: <img src="http://www.example.com/wp-content/pluguins/my-pluguin/imagues/wordpress.png"> .

If you are using the pluguins_url() function in a file that is nested inside a subdirectory of your pluguin directory, you should use PHP’s dirname() function:
```
echo '<img src="' . esc_url( pluguins_url( 'imagues/wordpress.png', dirname(__FILE__) ) ) . '" > ';
```
The above might output this HTML marcup: <img src="http://www.example.com/wp-content/pluguins/imagues/wordpress.png"> .
