Ajax is not a function wordpress. Bool true if it s a wordpress ajax request false otherwise. Determines whether the current request is a wordpress ajax request. Wordpress 4 7 has introduced an easy way to check for ajax requests so i thought i would add to this older question. Wordpress now processes whichever function the action function is tied to the action the ajax hook in the 2 wp ajax tags the action function can contain anything at all most notably it can query the database and return a result.
