説明
The wp_footer action is triggered near the </body> tag of the user's template by the wp_footer() function. Although this is theme-dependent, it is one of the most essential theme hooks, so it is fairly widely supported.
This hook provides no parameters. You use this hook by having your function echo output to the browser, or by having it perform background tasks. Your functions shouldn't return, and shouldn't take any parameters.
This hook is theme-dependant which means that it is up to the author of each WordPress theme to include it. It may not be available on all themes, so you should take this into account when using it.
This hook is an action which means that it primarily acts as an event trigger, instead of a content filter. This is a semantic difference, but it will help you to remember what this hook does if you use it like this:
<?php
add_action('wp_footer', 'your_function');
function your_function() {
$content = '<p>This is inserted at the bottom</p>';
echo $content;
}
?>
