Let’s take a closer look at the details of WordPress wp_footer.

WordPress wp_footer

The wp_footer() function initiates the wp_footer action close to the tag of the user’s template. Although this depends on the theme, it is one of the most crucial theme hooks, so it has a fair amount of support.

No parameters are offered by this hook. This hook is used to perform background tasks or to have a function echo output to the browser. The functions shouldn’t take any parameters or return anything. The author of each WordPress theme must decide whether to include this hook because it is theme-dependent. We should be aware of this when using it because it might not be available on all themes.

When used, this function’s default output is the admin panel, which is displayed at the top of the theme. Because the majority of plugins tie their script files or functions to this hook, it should be kept in the footer of every theme. Since this hook is an action, it primarily serves as an event trigger rather than a content filter. Although it is merely a semantic distinction, it will aid in our memory of what this hook does.

How to Add Content to the Site’s Footer Using wp_footer ?

1. Firstly, we launch a text editor and open the plugin file.
2. Then, we insert the line add action("wp_footer", "function_name");.

   The code we run here will run before the markup for the page has completely closed and been sent back to the client because almost every WordPress theme includes the wp_footer action hook.
3. Finally, to create the markup, create the function (function_name()). Ensure the markup is echoed by the function. We don’t send anything back to WordPress because this is an action hook. Instead, if we want it to print all the way to the last page, we must force it to.
