Update jQuery Version to 3.x

  • Hello Everyone,

    We are facing an issue with lower version of jQuery included in WordPress. We found the hook to implement latest jQuery in front-end of WordPress, however there is no way to include latest jQuery in WP Admin area except replacing the jquery.js file at /wp-includes/js/jquery.

    Is there a way to achieve this without modifying WP Core files?

    If we use the hook admin_enqueue_scripts it includes latest jQuery below the load-scripts.php file and shows error of dependency.

    Any help would be appreciated. Thanks.

  • Hi Nikhil

    You can indeed add your own version of jQuery without modifying the core code (never do this). To do this use the following code – https://codepad.org/A2seaiS7 in your functions.php

    If you aren’t confident editing theme files then there are plugins such as jQuery version control which enables this feature too.

    Hello Garethgillman,

    Thanks for your quick response. The code mentioned at https://codepad.org/A2seaiS7 will change the jQuery version for WordPress front-end site i.e. https://www.MYWEBSITE.com. However, it won’t change jQuery version in WordPress admin area i.e. https://www.MYWEBSITE.com/wp-admin/

    There is a hook admin_enqueue_scripts similar to wp_enqueue_scripts for admin area but admin behaves differently than front-end website. It has technique to load all the scripts in load-scripts.php file as per the need on specific page. Here, admin_enqueue_scripts adds the new version jquery below the load-scripts.php file which has already loaded other jQuery dependent scripts such as UI, Sorting, Widgets, etc… Therefore it is showing jQuery not defined error. To resolve this I believe we need a way to load latest jQuery before the load-scripts.php file is rendered and I am not sure if is there any WP hook available to do this.

    Let me know if that makes sense? Thanks.
