What is the issue with uploading files using xajax in PHP, and how can it be resolved?

The issue with uploading files using xajax in PHP is that xajax does not support file uploads directly. To resolve this issue, you can use a combination of xajax for form submission and regular PHP for handling file uploads.

// PHP code snippet to handle file uploads using xajax

// Check if the form has been submitted
if(isset($_POST['submit'])) {
    // Handle file upload using regular PHP
    $target_dir = "uploads/";
    $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
    
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". htmlspecialchars( basename( $_FILES["fileToUpload"]["name"])). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}

// xajax function to submit the form
function uploadFile($form_data) {
    xajax_processForm($form_data);
}
