How to use atom_author action in WordPress

Hey there, fellow WordPress enthusiast! Today, we’re diving into the **atom_author** action hook. This handy hook fires at the end of each Atom feed author entry. Let’s see how you can work with it!

To use the **atom_author** action, first, you need to register it using `add_action`. You can write this code into the `functions.php` of your activated theme or in a custom WordPress Plugin. At WePlugins, we always prefer creating a custom WordPress Plugin for using hooks to ensure nothing breaks when you update your WordPress Theme in the future.

In the examples below, we have defined a function `weplugins_execute_on_atom_author_event` and registered it using `add_action`. The first parameter `atom_author` is the name of the hook, the second parameter `weplugins_execute_on_atom_author_event` is the name of the function 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 to the registered function.

Sometimes, you may need to remove a registered hook, and for that, you can use `remove_action` to remove the **atom_author** action.

Examples

Example 1: Basic Hook Registration

Here’s a basic example of how you can use this hook to execute a function when the action occurs.

function weplugins_execute_on_atom_author_event() {
    // Code to be executed when atom_author action is triggered.
}

// Add the action
add_action("atom_author", "weplugins_execute_on_atom_author_event");

Example 2: Removing a Hook

If you need to remove a previously registered hook, you can do so with the `remove_action` function. Ensure you provide the same callback function name, priority, and number of arguments while removing the hook callback.

remove_action("atom_author", "weplugins_execute_on_atom_author_event");

Example 3: Using Priority and Arguments

In this example, we demonstrate how to use priority and arguments with the `add_action` function.

function weplugins_custom_atom_author_event($arg1, $arg2) {
    // Code using the passed arguments
    echo $arg1 . ' ' . $arg2;
}

// Add the action with priority and arguments
add_action("atom_author", "weplugins_custom_atom_author_event", 10, 2);
