Question

I have a form with Name : input and a submit. When pressed, it posts to the same php file. My first check is basically if(!$name) { call jquery to insert error class }. I have the jquery set up in a function but I’m not sure how to call the function from the if statement.

Answer 1

You need to do your check in javascript / jquery and avoid posting to the php file until the javascript validation is completed / satisfactory.

Then in php you need to validate again in case the visitor has javascript disabled.
