I am using a plugin which has the following function: See end of question.

And I've created a hook in my template file:

<?php custom_hook(); ?>

And this is what I have in my functions.php

function custom_hook() {
    do_action('custom_hook');
    echo 'Custom Hook works!';
}

add_action('custom_hook', 'wnw_overall_rating_comments', 1);

I am curious, as why this isn't loaded. I have even edit the add_action to the plugin to see if my filter works,

add_action('custom_hook','wnw_overall_rating_comments');

But no luck.

Am I missing something here?

add_action('the_content','wnw_overall_rating_comments');
function wnw_overall_rating_comments($content)
{
    global $post,$rating_table_name,$wnw_multi_rating_table,$multi_rating_image_on,$multi_rating_image_off,$multi_rating_image_half,$wpdb;

    if($post->type != 'page')
    {
        //some function

        }
        return $content.$rating_value;
    }else
        return $content;    

}

This answer explains how you should work with hooks/filters and themes/plugins. In short: Does the string from custom_hook then echo in your template? Btw: The add_action() call should reside in your plugin. Not in the theme. –  kaiser Oct 14 '12 at 19:33

You are adding to custom_hook in one code snippet and the_content in another... So which one is it? –  Rarst Oct 14 '12 at 19:33
    
Dear @kaiser, thank you for the article. I have been reading and trying different method to solve this. And following the Example 1. What I do now is adding this on the theme file <?php do_action('custom_hook'); ?> And add the action add_action('custom_hook','wnw_overall_rating_comments'); on the plugin. That didn't work as it should. I'm trying to understand why it didn't pulled. –  Mohd Rafie Kamaruzaman Oct 16 '12 at 13:26
    
Because you need to echo... And please answer @Rarst question. Thanks. –  kaiser Oct 16 '12 at 13:31
    
@Rarst What I am trying to do is to pull the function from the plugin and execute it elsewhere in the theme. The current situation, the plugin execute the code at the the_content and I want it to execute at the custom_hook But which bit should I echo as you suggest? Pardon my lack of knowledge. –  Mohd Rafie Kamaruzaman Oct 16 '12 at 13:47

You're simply missing the return print or echo statement (instead of just return).
