Adding text before footer in wordpress

Question

I've been reading the wordpress codex and it seems that if I want to add some text just before the footer shows up I should use code like this in my functions.php

add_action('wp_footer', 'your_function');

function your_function() {
  $content = '<p>This is inserted at the bottom</p>';
  echo $content;
}

It is my understanding that the $content should show up just before the footer, but it does not show up at all. Is there another way to show up my code just before the footer ?

I am with WP 2.8 but this should not matter

Answer 1

If you want to add something right before the footer (not in the middle of it), use

add_action('get_footer', 'your_function');

That hook runs when the theme file calls the get_footer() function.

Answer 2

Your code is valid. Just make sure your theme actually fires the "wp_footer" action: somewhere in footer.php probably there must be either do_action('wp_footer') or wp_footer()
