How to use delete_transient_transient action in WordPress

delete_transient_transient Action

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

To use delete_transient_transient 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 execute_on_delete_transient_transient_event which takes 1 parameter and we registered it using add_action. The first parameter delete_transient_transient is the name of the hook, the second parameter execute_on_delete_transient_transient_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_transient_transient action.

Parameters

Below the 1 parameter is required to use this hook.

• $transient : (string) Transient name.

Live Example 1: Basic Usage

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

    function weplugins_execute_on_delete_transient_transient_event($transient){
       //You can write code here 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_transient_transient", "weplugins_execute_on_delete_transient_transient_event" , 10, 1);
    

Live Example 2: Removing the Hook

To remove a hook callback, use the example below.

    remove_action( "delete_transient_transient", "weplugins_execute_on_delete_transient_transient_event", 10, 1 );
    

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

Live Example 3: Custom Implementation

Here is another example where we do something custom when the transient is deleted.

    function weplugins_custom_on_delete_transient($transient){
       if( $transient == 'my_custom_transient' ){
           // Custom code to execute when 'my_custom_transient' is deleted.
           error_log('My custom transient was deleted');
       }
    }
    add_action( "delete_transient_transient", "weplugins_custom_on_delete_transient", 10, 1 );
