How can I get php class methods in AJAX Call? - php

Question

I am creating a mobile app with Phonegap. Because the project is server-based, I use JQuery and AJAX to connect to php files lying on a server. Now I am having the following problem:
I make a AJAX call to, say, the php file login.php by
$.post('http://example.com/php/login.php',
{
}).success(
function(data){
console.log(data);
}).error(
function(data){
//return error
console.log("Error post ajax " );
},'json');
In login.php I want to use class methods, where the class is written in another php file, class.php.
So login.php looks like this
<?php
require_once('http://example.com/php/class.php');
$test = $class->test();
echo json_encode($test);
?>
and class.php looks like this:
<?php
class CLASS {
public function test(){
echo "test";
}
}
$class = new CLASS;
?>
But I can not use the method test() in the class CLASS. If I write the CLASS in the login.php file, of course it works, but this is not what I want.
Has anyone some tipps for me how to tackle this problem?

Answer 1

You should be instantiating the class in login.php by convention.
This:
$test = $class->test();
Should be this:
$test = new CLASS();
$test->test();
I think you said this is not what you want, so this might fix your issue:
You are not declaring the $class variable correctly:
This:
$class = new CLASS;
Should be this:
$class = new CLASS();

Answer 2

You need to learn a few basics, for example from this tutorial http://tut.php-quake.net/de/, and get some things straight. Many things you do are plain wrong
require_once('http://example.com/php/class.php');
you do not include like that, you include the raw path on your server, not an URL
require_once('/path/to/your/file/class.php');
More like this.
$test = $class->test();
this also will not work when your function looks like
public function test(){
echo "test";
}
this, your function has to return the value
public function test(){
return "test";
}
to achieve what you try.... consider getting some basics straight first would be my first advice, keep in mind I just want to help you because you will struggle more often if you don't get those basics and know the language you are using ;)
