WordPress’ New Action Hook to Put Code Immediately After the “body” tag

Great news for WordPress developers – WordPress now has a theme action hook to put code immediately after the <body> tag! It’s called “wp_body_open“. The new tag was included in WordPress 5.2 in May 2019, and is slowly being adopted by theme developers (e.g. It was added to Beaver Builder Theme in April 2020 – screengrab below).

No more having to hack your theme to put Google Tag Manager or other scripts in the <body> section of your website! Just use an action hook in either functions.php or your functional plugin like so:

// Add code just after <body> tag
function custom_content_after_body_open_tag() {
    ?>
    <script>Custom script here</script
    <?php
}
add_action('wp_body_open', 'custom_content_after_body_open_tag');

Is this helpful?

How to merge two folders, including all sub-folders and files, on Mac

By The Mighty Mo! Design Co. | November 3, 2022

Today I had an issue where I needed to merge two folders, each of which contained many sub- and sub-sub folders that had lots of images. After a lot of trial-and-error and some Googling, I found the best solution is to use the “ditto” command in Terminal like this: That’s it! Hat tip to AppleInsider.
