How to add content to the bottom of WordPress pages using wp_footer

The WordPress wp_footer function is used to output the closing tags for the theme’s footer section. This function is typically used in the theme’s footer.php file to ensure that any necessary scripts or content are loaded before the closing and tags.

Using the wp_footer function is useful for ensuring that all necessary scripts, such as JavaScript files or tracking codes, are included in the footer of the theme. This can help improve the performance and functionality of the website, as well as ensure that all essential content is loaded before the page finishes rendering.

Parameters and Return Value of wp_footer Function

The wp_footer function does not accept any parameters. It is a standalone function that does not require any input from the user.

Additionally, the wp_footer function does not return any value. It is used to include necessary scripts and styles in the footer of the WordPress theme, but it does not produce any output that can be captured or manipulated.

Examples

How to add a simple wp_footer function

Here’s a simple example of using the wp_footer function in your WordPress theme:

<?php
function my_custom_footer_function() {
 // Add custom footer content here
}
add_action('wp_footer', 'my_custom_footer_function');
?>

This code snippet adds a custom function my_custom_footer_function to the wp_footer action hook. This allows you to add custom content or scripts to the footer of your WordPress theme.

How to conditionally add a wp_footer function

Here’s an example of using the wp_footer function conditionally based on a specific page template:

<?php
function custom_footer_for_specific_template() {
 if (is_page_template('custom-template.php')) {
 // Add custom footer content here
 }
}
add_action('wp_footer', 'custom_footer_for_specific_template');
?>

This code snippet checks if the current page is using a specific page template (in this case, custom-template.php) and then adds the custom footer content only if the condition is met.

How to enqueue scripts using wp_footer function

Here’s an example of using the wp_footer function to enqueue scripts in the footer of your WordPress theme:

<?php
function enqueue_custom_scripts_in_footer() {
 wp_enqueue_script('custom-script', get_template_directory_uri() . '/js/custom-script.js', array('jquery'), '1.0', true);
}
add_action('wp_footer', 'enqueue_custom_scripts_in_footer');
?>

This code snippet uses the wp_enqueue_script function to enqueue a custom script called custom-script.js in the footer of the theme. The true parameter indicates that the script should be loaded in the footer.
