I have a large form using html and php, but I would like to use javascript to check my mysql database for verification and auto fill support. Like if I wanted the second field when entered to automatically check my database to see if theirs already a record with that form data and then either give me a messege or auto fill the rest of the fields with the database data. How would I go about achieving this?

If you want to check it on the fly without submitting the form data to the server, you’ll have to use AJAX. Essentially an AJAX call will request a page on your server that does the query with the given parameters, then it returns the results (typically HTML or a JSON object). There are many different AJAX libraries to choose from
