How to pass a variable to a php page?

I am very new to jQuery and javascript. I have an autocomplete box setup (from jQuery UI). After the user selects his value from the search box, how do I pass that value to another php page (ie getmatches.php, which will look up that value in our database). I have: 

$(function(){
      $("#my_cell").autocomplete({
      source: "autocomplete.php",
      minLength: 1,
          delay: 0, 
      select: function (event, ui) {
          // what goes here?    

      }
     });
    });

jQuery Autocomplete by default is passing the value of the input to the source you've specified through GET parameter called term. So if you type for example world it will do a request to autocomplete.php?term=world

I highly do not recommend to do AJAX requests inside the SELECT event handler function. Unless you mean something else (like tracking that).

you can either attach a get param to url like this:

source: "autocomplete.php?param_name=" + document.getElementById("myfield").value,

but I think the $.autocomplete plugin function may provide API for sending parameters to backend, I think you should read documentation for it, in most cases docs specify everything you need

You can use GET parameters like so:

http://yourserver/getmatches.php?search=<yoursearchstring>

In getmatches.php, retrieve the variable.
