jquery call for a remote php function

Question

Hi, I have a selectbox that needs to be updated dynamically. I am using jquery to perform that using .load($url), where $url is the location of the php file to call. I am wondering if there is a way to call a specific function within that php file instead of calling the entire php file.

Answer 1

no, you can't. but you can pass GET parameters to the URL, and use that URL as a controller. for example:

.load("/ajax_controller.php?action=whatever")

Answer 2

You can pass a parameter to PHP script and user switch in script to select which action needs to be done

Answer 3

You could send a GET parameter as part of the AJAX request e.g. blah.php?func=1

Then in your PHP file:

if ($_GET['func'] == 1) {
    do_something();
}
else {
    do_something_else();
}

Or you could use something like CodeIgniter that structures its URL's as controller/function/parameter
