Question

i am thinking of building an android app in appcellerators titanium application, and i have a question, the website which the app is for is built using php/mysql, and what i am wondering is, as titanium works using javascript, html and css only, is there a way i can pull the data dynamically from my database using javascript?

if this has already been posted I’m sorry i searched and couldnt find it :S

Answer 1

With PHP, take your database response array and encode it like this:

<?php
json_encode($db_array);
?>

More information:
http://php.net/manual/en/function.json-encode.php

Note that you’ll need PHP 5.2 or above in order to have the built in JSON functions for PHP.

In Titanium, you want to open a XHR (or network handler) to grab the data:

var xhr = Ti.Network.createHTTPClient();
var.onload = function()
{
   try
   {
      data = JSON.parse(this.responseText);
   }
   catch (excp)
   {
      alert('JSON parse failed');
   }

   // you should handle your network async, meaning you should handle any renders or any post elements here. if you make it sync, you'll cause all other handlers and functions to work improperly (like click events, etc).
}

xhr.open("GET", "your url here");
xhr.send();

You can access the the data array by simply calling data[0].some_col;
