Passing variable to remote php file for JSON data - php

Question

I am building a mobile app using Titanium Studio, build: 3.1.1.201303242433, CLI version 3.0.24, Titanium SDK version 3.0.2.GA, iOS SDK: 6.1, iPad Simulator: 6.1 on MAC OS X10.7.5.
I am attempting to retrieve JSON data from a remote database. The database has records with and without a "sectionid" (sectionids are numbers 1-12). I want to retrieve the records with the "sectionid" I pass to my query. Here are the steps I am following: First I assign a "sectionid" to a tableViewRow like this:
leftImage:'images/advertising.png',
title:'Advertising',
sectionid: '1',
color:'#000',
font: {fontWeight:'bold', fontSize:16},
height:'44dp',
hasChild:true,
test:'testcatmenu.js'},
Then I pass the sectionid to another file like this:
var section = e.rowData.sectionid;
win.section = section;
In the next file I get the sectionid and pass it to the remote php file like this:
var section = Ti.UI.currentWindow.section;
var url = "http://mydomain.com/myfile.php?sectionid='section'";
Finally, in the php file I $_GET the sectionid and use it in my MySQL query like this:
$result = mysql_query("SELECT name FROM `cms_client` WHERE sectionid = '" . mysql_real_escape_string($_GET['section']) ."'") or die('Could not query');
The php file is returning the records that do not have a sectionid, so somewhere I am losing the sectionid? I do not know where my code syntax is wrong, would someone be so kind to show me the correct syntax that I need to make this work?

Answer 1

In the php you are using a variable $_GET['section'] but the GET variable you are passing in is called sectionid (?sectionid=). So either change both to section or both to sectionid.
Also, assuming that the
var url = "http://mydomain.com/myfile.php?sectionid='section'";
is javascript then it should be something like:
var url = "http://mydomain.com/myfile.php?sectionid="+section;

Answer 2

var url = "http://mydomain.com/myfile.php?sectionid='section'";
Change that to
var url = "http://mydomain.com/myfile.php?sectionid="+section;
Javascript allows you to add variables to a string using + variableName
Like
var variableT = "foobar";
var strNew = "This string contains the word: "+variableT+" and it works!";
