Question

EDIT:
I will try to explain what I want to do a bit better. I am displaying a table with all the fields retrieved from a database using an ajax call to a php file (eg. other.php) in my main.php. What I am trying to figure out is once the table is displayed to screen and the call is in the other.php file, can I implement an update query within other.php to update a field in the database with a user input? Does that make sense?
Thanks.

Yes, it’s possible. Assuming that you have a form that the user fills before clicking in the menu, you can add this values in your ajax call.

For example, assuming that you have a search button

<input type='text' name='search' id='search' />

You can pass this to your php with get or post (type of request)

$.ajax({
  url: "somefile.php",
  type: "POST",
  data: "search=" + $('#search').val(),
  success: function(data){
    //do something...
  }
});

And in your somefile.php you can access the value with $_POST['search'] or $_GET['search'] (depending of the type of the request).

I think with this you can adapt to your reality. More samples you can get in the JQuery docs.
