jQuery Ajax returns the whole page

Question

I have a jquery-ajax function that sends data to a php script and the problem is with the return value, it returns the whole page instead of single value.

Thank you

Sophia, In your case, you should not send your data to a php file that, if viewed by a web browser, displays a website page. You should send your information to a php file that only returns the data that you would like to see returned.

So instead of "index.php", create a file called something like "my-ajax-script.php". That file should include any necessary "include()" files to connect to the database and your php function files (ie: for sanitizing the POST data). Then the file should have the code that processes the POST data, and echo's out the data complete with some html tags. This data will be inserted into your existing DOM (html markup).
