ACF field true/false

Hello,

I created a true / false type “notify by email” custom field in ACF. I would like that when the toggle is on “true” it sends the administrators an e-mail indicating “New post published on the site. Find it here: …..”.

For the notification e-mail, it works fine unconditionally, so send notification systematically after publishing a new post. On the other hand, when I try to add if (get_field (‘my-custom-field’)); to my code this does not work. It doesn’t matter if the field is active or not it does not send an email.

Here is my code:

add_action( 'publish_post', 'send_notification' );
function send_notification( $post_id ) {
	if(get_field('my-custom-field')) {

        $args = array (
            'role' => 'administrator',
			'role' => 'subscriber'
        );

        $user_query = new WP_User_Query( $args );

         $email_addresses = array();
        foreach ( $user_query->results as $user ) {
            $email_addresses[] = $user->user_email;
        }

        $post_title = get_the_title( $post_id ); 
        $post_url = get_permalink( $post_id ); 
        $subject = "New post published";
		$message = "Hello,\n";
        $message .= "The post has just been published :" . $post_url . "\n\n";
	    $message .= "Thank you.";

        wp_mail($email_addresses, $subject, $message );
	}
}

Can you help me please ?

Thank you so much!

The problem is that ‘publish_post’ happens before save_post and ACF saves values on the latter. This means that you are attempting to get a value that ACF has not yet set.

You either need to use the acf/save_post hook with a priority > 10 or you need to look for the value in $_POST[‘acf’]
