best way to customize core functions like wp_update_post

  • I want to add some custom functionality to wp_update_post() to send an email each time a post is updated. Updating the core file (wp-includes/post.php) is obviously not a good idea since each time I upgrade WP my customizations would get overwritten. So, what’s the best way to go about this? Can I copy the function from the core file into my theme’s functions.php file to do the override? If so, is there a special naming convention to get it to work (there is something similar in Drupal).

    Thanks in advance!

  • Add to your functions.php replacing myCustomFuction with the name of the function you create to do what you want during a post.

    add_action ( 'publish_post', 'myCustomFunction' );

    Thanks, dralezero! I was thinking it was something along those lines. I’ll give it a shot!

    I tried this out but nothing seems to happen. In the documentation it mentions “Action function arguments: post ID”. Do I need to pass an ID? If so what is the syntax to grab the ID and call add_action?

    Here’s what I have in my theme’s functions.php file so far:

    function dci_email_answer() {

	if (have_posts()) : while (have_posts()) : the_post();

		$strMailTo = '[email protected]';
		$subject = 'Answer from mywebsite.com';
		$email = '[email protected]';
		$mailBody = "Thank you for submitting a question!  Click here to view the answer. <br /><br /> " . the_permalink();

		mail($strMailTo, $subject, $mailbody, "From: $email");
		header("Location: https://www.mywebsite.com");

	endwhile; endif;

}

add_action('publish_post', 'dci_email_answer');

    Figured it out! I needed to pass $post_ID into my custom function and not use the loop in the function.

    function dci_email_answer($post_ID) {
//just do your stuff
}

add_action('publish_post', 'dci_email_answer');
