Wordpress get plugin directory

Question

Is there any function that would return the full path of my plugin in WordPress?

Example is

path/wp-contents/plugins/myplugin

I have tr

Answer 1

As noted on the section Common Usage of Plugins Url function reference page, that's what worked for me:

If you are using the plugins_url() function in a file that is nested inside a subdirectory of your plugin directory, you should use PHP's dirname() function:

echo plugins_url('', dirname(__FILE__) );

The output for this was:

http://domain/app/wp-content/plugins/my-plugin

The file that called the function was my functions.php inside includes, so the complete path to my file was:

http://domain/app/wp-content/plugins/my-plugin/includes/functions.php

Answer 2

plugin_dir_path( __FILE__ ) will give you plugin path of current file.

this is mean if you call this function like that inside "your_plugin_dir/sub_dir/file.php" will return "your_plugin_dir/sub_dir/"

if you want to get the ROOT of your plugin directory, just change __FILE__ to __DIR__

plugin_dir_path( __DIR__ )

Answer 3

Unfortunately, most of the answers here seem to forget about one important thing.

In addition to the plugins dir, plugins might be also in the Must-use plugins (mu-plugins) directory

Because of that, we need to check multiple directories.
An example function to do this:

function get_plugin_dir_path($pluginFolderName){

    if ( defined( 'WPMU_PLUGIN_DIR' ) && file_exists( trailingslashit( WPMU_PLUGIN_DIR ) . $pluginFolderName ) ) {
        return trailingslashit( WPMU_PLUGIN_DIR ) . $pluginFolderName;
    } elseif ( defined( 'WP_PLUGIN_DIR' ) && file_exists( trailingslashit( WP_PLUGIN_DIR ) . $pluginFolderName ) ) {
        return trailingslashit( WP_PLUGIN_DIR ) . $pluginFolderName;
    }
    return false;

}

You can define a variable into your main Php file. It should be at the root of your plugin folder. The file should be here : .../wp-content/plugins/plugin-folder/my-plugin.php

You can add into the file this line.

    define( 'MYPLUGIN__PLUGIN_DIR_PATH', plugins_url('', __FILE__ ) );

After you can use your new variable anywhere into your plugin.

    public function Test() 
    {   
            $folder2 = MYPLUGIN__PLUGIN_DIR_PATH . '/folder1/folder2/';
           // $folder2 = .../wp-content/plugins/plugin-folder/folder1/folder2/
    }

I hope it will help someone.

Answer 5

I will suggest following code. if you are accessing this function from any subfolder.

plugins_url( 'images/logo.png' , dirname(__FILE__ ));

Answer 6

As mentioned by @tsl143 the function plugins_url() is what you want, along with the __FILE__ magic constant. If you call it from a file inside your plugin folder it will refer to that folder.

Example:

For the directory:

echo plugins_url( '' , __FILE__ ); 
//outputs: http://www.example.com/wp-content/plugins/my-plugin    

For a file or subdirectory in your plugin directory:

echo plugins_url( 'images/logo.png' , __FILE__ ); 
//outputs: http://www.example.com/wp-content/plugins/my-plugin/images/logo.png
