Jquery ajax call from javascript to PHP

Question

There seems to be a problem with the code I have for calling php from javascript with jquery ajax. The ajax call seems to be successful but I don\'t get the correct informa

Answer 1

I send back the query as a reponse to debug it before performing a delete query.

...

this ajax call returns an empty string and causes the div in the HTML to disappear.

I assume you want the query displayed inside your div. You need echo($sql); or echo(uptree()); or equivalent somewhere in your program. You might also create an HTML form that POSTs the same data as your AJAX to see what PHP is returning.
