Function not attaching to wp_footer hook

Does the template in use include:

<?php get_footer(); ?>

??

Typically, it’s the last line.

Hey ??
Yes it does

It looks like you are missing the

<?php wp_footer();?>

in footer.php

Hey Birgire,

No, I have the wp_footer(); in the footer.php file. My other function are working fine that are attached to it.

What happens if you skip the first if-sentence ?

Just to see if it runs then?

Here is the page i’m working on

https://www.learnwebdevelopment.com/crazy

or mabye you need

global $post;

insde the function to get access to the value of $post->ID

I tried that also but to no avail.

This was the code I tried:

//if ( is_page_template('template-thankyou.php') ) {

		function eh_add_product_tracking_code(){
			global $post;

			$meta_key = 'product_code';
			$meta_value = get_post_meta($post->ID, $meta_key, true);

			if ($meta_value = ''){
				$meta_value = "This is Blank!";
			}else{
				return $meta_value;
			}
		}

		add_action('wp_footer', 'eh_add_product_tracking_code');

//}

for the debug you could try

if (strlen($meta_value)<1){
    $meta_value = "This is Blank!";
}
return $meta_value;

instead of

if ($meta_value = ''){
    $meta_value = "This is Blank!";
}else{
    return $meta_value;
}

I added that and no dice.

This is the template page:

This is the footer.php:

And the function:

I think this will help more

aha, think I found it:

use

echo $meta_value;

instead of

return $meta_value;

??

Tried that also. I’m just going to go another approach at this and do it via a separate footer ??

damn ??

strange, I can’t see this comment

<!-- /#wrapper -->

in the html source for

https://www.learnwebdevelopment.com/crazy/:

Looks like we have to go back to the basics and try:

<?php
function mydebug(){
   echo "debug";
}
add_action('wp_footer', 'mydebug');
?>

or can you maybe use the action on

add_action( 'woo_foot' , 'mydebug');

instead of

add_action( 'wp_footer' , 'mydebug');

?

it looks like the definition of woo_foot() is

function woo_foot() { do_action( 'woo_foot' ); }

so the action hook woo_foot should work in theory ??
