register_deactivation_hook( string $file, callable $callback )

Sets the deactivation hook for a plugin.

Contents

Description

When a plugin is deactivated, the action ‘deactivate_PLUGINNAME’ hook is called. In the name of this hook, PLUGINNAME is replaced with the name of the plugin, including the optional subdirectory. For example, when the plugin is located in wp-content/plugins/sampleplugin/sample.php, then the name of this hook will become ‘deactivate_sampleplugin/sample.php’.

When the plugin consists of only one file and is (as by default) located at wp-content/plugins/sample.php the name of this hook will be ‘deactivate_sample.php’.

    Examples
    If you have a function called myplugin_deactivate() in the main plugin file at either

    wp-content/plugins/myplugin.php or
    wp-content/plugins/myplugin/myplugin.php
    use this code:

    register_deactivation_hook( __FILE__, 'myplugin_deactivate' );

    This will call the myplugin_deactivate() function on deactivation of the plugin.

    If you are using a namespace in the main plugin file
    namespace MYNAMESAPCE;

    you will need to use the __NAMESPACE__ keyword in your code for register_deactivation_hook.
    register_deactivation_hook( __FILE__ , __NAMESPACE__ . '\deactivate_plugin' );

    Otherwise, the code will be unable to find the function deactivate_plugin() and will produce a warning:
    PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘deactivate_plugin’ not found.
