Is Valums Ajax file Upload capable of handling the uploaded file?

Currently, I am utilizing the Valums Ajax Fileupload script found at

These are the settings I have configured:

function createUploader(){            
    var uploader = new qq.FileUploader({
        element: document.getElementById('file-uploader-demo1'),
        action: 'photo.php?mode=upload',
        debug: true
    });           
}

When attempting to handle the uploaded files within photo.php?mode=upload, I encountered the following issue:

if(isset($_FILES['qqfile'])){
$filename = $_FILES['qqfile']['name'];
$imageSizeInfo = getimagesize($filename);
}

Unfortunately, it seems that the isset condition for $_FILES is not being executed. Is there a configuration setting that I may have overlooked? Removing the if statement results in a getimagesize error indicating that the parameter cannot be empty.

Answer №1

The Valums upload script, available in the latest version, utilizes ajax (xhr stream) for sending file information when using browsers like Firefox, Chrome, and Safari. However, Internet Explorer versions 6 through 9 do not support this feature and instead rely on iframe support to properly populate the $_FILES array.

For those who prefer to stick with the super global $_FILES array across all browsers, the older version of the Valums script found at this link can be used as an alternative solution.

Answer №2

In the valums script, there are two main methods for file upload: qqUploadedFileXhr and qqUploadedFileForm. By default, the example script uses qqUploadedFileXhr.

If you want to retrieve the file's information, you can simply use: $file_name = $_GET['qqfile']; this will give you just the filename.

However, if you decide to use 'qqUploadedFileForm', you can access more file information:

  • $_FILES['qqfile']['name'] for the filename
  • $_FILES['qqfile']['size'] for the size, and so on
