This is more tricky. I basically see two ways:

1. Looking for a string in your editor when you know the file, or 
looking via "git grep" when you don't know which file

2. Using an IDE like NetBeans where you can track the execution path at 
the PHP level and set watchpoints (but I'm not sure about watching 
$_POST variables)

In this case, since it comes from a POST, most likely it's located in a 
form so you can start by searching for forms in sql.php.
