I'm trying to do a feature whereby when the LIKE button is clicked, the total likes is displayed on the screen without reloading the page. The code i'm showing below is used to obtain the comments under a specific article, including the likes for each comment. All is working fine at this stage, but how do I pass it to a AJAX/implement an AJAX on the script.when the LIKE Button is clicked, what link in used in the < a h ref =" " >?Is AJAX written alone or inside the PHP?How do I make it not go away from the current page, while still having the updated likes display from the database?Please I'm not looking for a do all code, all I need is just how to get myself started with this.Thanks for your time and effort. I most appreciate it.Thanks \[code\]$query6 = mysql_query(" SELECT c.user , c.body , c.date, c.like FROM comment AS c INNER JOIN about_ AS ac ON c.article_id = ac.about_id WHERE c.article_id = '".$article_id."'
