How Do I Create a Custom Hook in WordPress?

Creating a custom hook in WordPress is a relatively easy process. To begin, open the WordPress hooks file located at wp-content/plugins/yourplugin/hooks. Once inside, you’ll see a list of all of the available hooks. To create a custom hook, first identify the function you wish to create a hook for. In the example below, we’re interested in creating a custom hook for the wp_ajax_save_post() function. Next, locate the function you wish to hook into and locate the appropriate hook template. In the example below, we’ll be using the wp_ajax_save_post() function and the wp_ajax_post_save_form() hook template. Once you have located the template, you’ll need to fill in the appropriate information. In the example below, we’re filling in the arguments and return values for the wp_ajax_save_post() function.

Once you have completed the template, you’ll need to save the file and return to the WordPress hooks file. Next, you’ll need to add the new hook to the appropriate location in the hooks file. In the example below, we’ve added the new hook to the wp_ajax_post_save_form() function. Finally, you’ll need to rename the original function to match the new hook name. In the example below, we’ve renamed the original function to wp_ajax_save_post_form(). Finally, you’ll need to update the plugin settings to include the new hook. In the example below, we’ve added the new hook to the plugin settings under the “Plugin Hooks” menu. Finally, you’ll need to publish the plugin and test the functionality.
