How can the script be modified to correctly recognize and upload images with different field names in PHP?

The issue can be solved by modifying the script to check for different field names for image uploads. This can be done by iterating through the $_FILES array and checking for different field names dynamically. By doing this, the script can correctly recognize and upload images with different field names. 

<?php

// Check for different field names for image uploads
foreach ($_FILES as $key => $file) {
    if ($file['error'] == UPLOAD_ERR_OK) {
        $uploadDir = 'uploads/';
        $uploadFile = $uploadDir . basename($file['name']);
        
        if (move_uploaded_file($file['tmp_name'], $uploadFile)) {
            echo "File is valid, and was successfully uploaded.\n";
        } else {
            echo "Possible file upload attack!\n";
        }
    }
}

?>
