How to use delete_option_option action in WordPress

delete_option_option action

The dynamic portion of the hook name, $option, refers to the option name.

To use delete_option_option action, first you have to register it using add_action. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at WePlugins, always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function weplugins_execute_on_delete_option_option_event which takes 1 parameter and we registered using add_action. The first parameter delete_option_option is the name of the hook, the second parameter weplugins_execute_on_delete_option_option_event is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times, and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometimes, you have to remove a registered hook so you can use remove_action to remove delete_option_option action.

Parameters

• $option: (string) Name of the deleted option.

Live Example

Example 1: Basic Hook Registration

Below is an example of how you can use this hook.

    function weplugins_execute_on_delete_option_option_event($option) {
        // Code to be executed when this action occurs in WordPress.
        // Use the parameters received in the function arguments & implement the required additional custom functionality according to your website requirements.
    }
    // Add the action
    add_action("delete_option_option", "weplugins_execute_on_delete_option_option_event", 10, 1);
    

Example 2: Removing a Hook Callback

To remove a hook callback, use the example below.

    remove_action("delete_option_option", "weplugins_execute_on_delete_option_option_event", 10, 1);
    

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.

Example 3: Conditional Hook Execution

In this example, we conditionally execute the function based on the option name.

    function weplugins_execute_on_delete_option_option_event($option) {
        if ($option === 'my_custom_option') {
            // Specific code for 'my_custom_option' deletion
        }
    }
    // Add the action
    add_action("delete_option_option", "weplugins_execute_on_delete_option_option_event", 10, 1);
