Passing Multiple Variables to a PHP page

Question

I want to pass multiple variables city1 and area1 (JavaScript variables) in a URL to a PHP page I but got stuck in on the part shown below. What am I doing wrong?

$("#list").load("selectcity.php?city1="+city1&"area1="+area1);
$.ajaxSetup({ cache: false });

Your & needs to go inside of quotes: selectcity.php?city1="+city1"&area1="+area1 — John Conde

@AndyJones: the PROBLEM with the code was that the &s were outside of the "s! — Sumner Evans

The & character should be inside quotes and not outside quotes. This is the corrected code :

$("#list").load("selectcity.php?city1="+city1+"&area1="+area1);
$.ajaxSetup({ cache: false });

GET parameters are separated by the character &. You are passing 2 parameters to the file separated by &. The ? sign in the URL indicates that the next characters coming after it is the GET parameters.

Or you can use $.get which is very easy to set up and works fine like $.load :

$.get("selectcity.php", {"city1": city1, "area1": area1}, function(response){
 $("#list").html(response);
});

It is better not to form query string manually, since you will constantly encounter not-so-notable bugs. jQuery offers a way to construct query string automatically from object:

var ajaxData = {
    city1: city1,
    area1: area1
};
$.get('selectcity.php', ajaxData, function(data) {
    $('#list').html(data);
});

(jQuery documentation)

It requires slightly more code but is guaranteed to be safe. There is also a .load(url, data) shortcut, but it will send a POST request instead of GET request, and that's probably not what you want.

Also, i'm not sure jQuery will automatically urlencode manually-formed query strings, so string concatenation approach may introduce even more bugs.
