Run PHP code on button click

Question

What is the best way to just run a PHP script when the user clicks a button? It sends nothing back to the user whatsoever! (The PHP script only sends a PostgreSQL query.)

I have only found ways of returning data. I only want to run it.

Answer 1

You're looking for AJAX (asynchronous javascript). Just have a javascript function call the target script and either don't return anything OR don't do anything with the return value. Alternately, you could simply have form that submits to a hidden iframe on the page.
