I'm a fairly experienced programmer getting my head around PHP and Ajax for the first time, and I'm having a bit of trouble figuring out how to incorperate object oriented PHP into my ajax webapp.
I have an admin page (admin.php) that will load and write information (info.xml) from an XML file depending on the users selection of a form on the admin page. I have decided to use an object (ContentManager.php) to manage the loading and writing of the XML file to disk, i.e :
class ContentManager{
var $xml_attribute_1
...
function __construct(){
//load the xml file from disk and save its contents into variables
$xml_attribute = simplexml_load_file(/path/to/xml)
}
function get_xml_contents(){
return xml_attribute;
}
function write_xml($contents_{
}
function print_xml(){
}
}
I create the ContentManager object in admin.php like so
<?php
include '../includes/CompetitionManager.php';
$cm = new CompetitionManager()
?>
<script>
...all my jquery
</script>
<html>
... all my form elements
</html>
So now I want to use AJAX to allow the user to retrieve information from the XML file via the ContentManger app using an interface (ajax_handler.php) like so
<?php
if(_POST[]=="get_a"){
}else if()
}
...
?>
I understand how this would work if I wasn't using objects, i.e. the hander php file would do a certain action depending on a variable in the .post request, but with my setup, I can't see how I can get a reference to the ContentManager object I have created in admin.php in the ajax_handler.php file? Maybe my understanding of php object scope is flawed.
Anyway, if anyone can make sense of what I'm trying to do, I would appreciate some help!
