Function Reference/is plugin inactive

Description

Checks if a plugin is not activated.

This function is the logical negation of is_plugin_active(). Used as a callback.

Usage

In the Admin Area: <?php is_plugin_inactive($plugin?> In the front end, in a theme, etc... <?php include_once( ABSPATH 'wp-admin/includes/plugin.php' ); ?>
<?php is_plugin_inactive
($plugin?>

Parameters

$plugin
(string) (required) The name of the plugin sub-directory/file.
Default: None

Return Values

True
if plugin is not activated, else false.

Examples

<?php
// Makes sure the plugin is defined before trying to use it
if ( ! function_exists('is_plugin_inactive')) {
    require_once( 
ABSPATH '/wp-admin/includes/plugin.php' );
}

if (
is_plugin_inactive('plugin-directory/plugin-file.php')) {
    
//plugin is not activated
}
?>

Notes

The file that defines this function (wp-admin/includes/plugin.php) is only loaded in the admin sections. In order to use is_plugin_active outside the admin pages, it's necessary to include or require plugin.php before trying to use it (as shown in the example).

Change Log

Since Version 3.1

Source File

is_plugin_inactive() is defined in wp-admin/includes/plugin.php.
