How to use opml_head action in WordPress

opml_head action

Fires in the OPML header.

To use the opml_head 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_opml_head_event and we registered it using add_action. The first parameter opml_head is the name of the hook, the second parameter weplugins_execute_on_opml_head_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 the opml_head action.

Parameters

• No parameters

Live Example

Example 1: Basic Usage

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

    function weplugins_execute_on_opml_head_event(){
        // You can write code here to be executed when this action occurs in WordPress website according to your requirements.
    }
    // add the action
    add_action( "opml_head", "weplugins_execute_on_opml_head_event");
    

Example 2: Removing the Hook

To remove a hook callback, use the example below.

    remove_action( "opml_head", "weplugins_execute_on_opml_head_event");
    

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

Example 3: Custom Functionality

Here’s an example adding custom functionality to the OPML header.

    function weplugins_custom_opml_head_function(){
        echo '<!-- Custom OPML Header Code -->';
    }
    // add the action
    add_action( "opml_head", "weplugins_custom_opml_head_function");
