Question

So my project uses an MVC framework and I have a page with an Ajax script I run to get content from the server. When the PHP script is called in the Ajax script, I want to access the classes already in my library for use in the PHP script. To do this, I use what I call an ajaxBootstrap to call the appropriate function that then instantiates the objects needed for that specific Ajax script.

To load those classes from my library I have an autoload function in my ajaxBootstrap so I don’t need to use a bunch of require and include statements. My problem is those files aren’t being loaded due to a path issue with the autoload function. When I use a require statement with the same path, the classes load with no problems, its only when I try to load them using the autoload function that I get an 500 internal server error.

Here is my ajaxBootstrap file:

// This file routes Ajax requests made in JS files and instantiates a specific object to carry out the actions needed for that particular Ajax operation 

// Autoload any classes that are required
function autoLoad($classToLoad)
{
    if(file_exists('../library/' . $classToLoad . 'class.php')) // File in the library folder
    {
        require('../library/' . $classToLoad . '.class.php');
   }
    else if(file_exists('../../app/models/' . $classToLoad . 'class.php')) // File in the models folder
    {
        require('../../app/models/' . $classToLoad . '.class.php');
    }
}

spl_autoload_register('autoLoad');

// Determine which function to call based on the url that's listed in the Ajax request
switch($_GET['action'])
{
    case 'pageOne':
        pageOne();
        break;
    case 'pageTwo':
        pageTwo();
        break;
}

function pageOne()
{
    $test = new Test();
    $test->funcThatReturnStuff();
}

function pageTwo()
{
    $test2 = new Test2();
    $test2->funcThatReturnStuff();
}

Like I mentioned eariler, if I use a require statement such as:

require('../library/Test.class.php');
$test = new Test();
$test->funcThatReturnStuff();

The class loads and works just fine. But using the same path in the autoloader function throws an error. The really odd thing is if I put an else if statement in the autoloader that loads a class from the folder where my ajaxBootstrap is it also works fine too…

I know I could just use the require statements and be done with the problem but I want to be able to scale the project and not need to use loads of require statements in the future. BTW, I use ‘../’ to get from where my ajaxBootstrap file is to my other folders.

Also, to add to my previous post, I’ve tried replacing the ../ with absolute paths using define('ROOT', dirname(__FILE__) . '/') and also define('ROOT', $_SERVER['DOCUMENT_ROOT'] . '/path/to/folder/') neither of which worked and still gave me the internal server error in Firebug. In addition, I haven’t received any errors in my error log either.

Nevermind… Even after staring at my code for the past few hours I somehow missed the missing period in two of my file paths. I hate coding sometimes… Thank you to anyone who took time to read this.
