PHP autoloader - $classname includes the entire folder path and not just the class name itself?

Question

I am following WordPress's naming convention where a class My_Class should reside in the file named class-my-class.php. I used this autoloader for WordPress, written by Rarst. If I print out the $class_name variable, I see that the prefix class is appended to the folder name and not the class file. I had the same issue with some other autoloader I used earlier. I can do a little bit of string manipulation and get what I want but I want to know what is the exact issue.

What could be wrong?

What is your code looking like? How do you implement the autoloader class for wordpress? The autoloader itself only prepends a directory, if given in the constructor. Otherwise it 's the actuell directory the autoloader is located in. I guess you 're using the wrong classnames for instance. — Marcel, Jul 17 '15 at 10:02
I used an autoloader which is supposed to follow WP's coding standards. It works either ways. The classnames are right. — Rutwick Gangurde, Jul 17 '15 at 12:34

I just had a look at this autoloader you linked to, I would say it should be on line 21 something like this :

$class_path = $this->dir . '/class-' . strtolower( str_replace( '_', '-', basename( $class_name ) ) ) . '.php';

basename takes only the file part + file extension of the path.

You need also to check where this autoloader file is, because $this->dir is set to DIR, which is the directory where the autoloader file is.

It works, the class file is included. But I still get an error that the class is not found. – Rutwick Gangurde Jul 17 '15 at 15:32

Use a flexible loader. try this one.

function TR_Autoloader($className)
{
$assetList = array(
    get_stylesheet_directory() . '/vendor/log4php/Logger.php',
    // added to fix woocommerce wp_email class not found issue
    WP_PLUGIN_DIR . '/woocommerce/includes/libraries/class-emogrifier.php'
    // add more paths if needed.
);

// normalized classes first.
$path = get_stylesheet_directory() . '/classes/class-';
$fullPath = $path . $className . '.php';

if (file_exists($fullPath)) {
    include_once $fullPath;
}

if (class_exists($className)) {
    return;
} else {  // read the rest of the asset locations.
    foreach ($assetList as $currentAsset) {
        if (is_dir($currentAsset)) {
            foreach (new DirectoryIterator($currentAsset) as $currentFile) {
                if (!($currentFile->isDot() || ($currentFile->getExtension() <> "php")))
                    require_once $currentAsset . $currentFile->getFilename();
            }
        } elseif (is_file($currentAsset)) {
            require_once $currentAsset;
        }

    }
}
}

spl_autoload_register('TR_Autoloader');
