Question

I am using the Valum AJAX upload script from: https://github.com/valums/file-uploader
I am having trouble on how to get the file name and path stored into mySQL database.

---

Using the php.php I see there is the $pathinfo and $filename already

$pathinfo = pathinfo($this->file->getName());
$filename =  rawurlencode(str_replace(' ', '-', strtolower($pathinfo['filename'])));

I tried doing this, to store it into my db, but it doesn’t seem to be storing anything.

<?php require_once('../../Connections/connSQL.php'); ?>

It uploads successfully, just doesn’t store. Can anyone point me out the problem or provide an alternative solution to this?

Thanks so much for your help in advance!

Answer 1

After searching online for awhile, I found the solution:

apparently, there are two methods for upload in valums script, qqUploadedFileXhr and qqUploadedFileForm. If you use example script, then you use a default one : qqUploadedFileXhr.

so, to get the files info you can use : $file_name = $_GET[‘qqfile’]; that’s it, just filename only.

but, if use the ‘qqUploadedFileForm’, you can get the files info : – $_FILES['qqfile']['name'] for filename – $_FILES['qqfile']['size'] for size – etc

Fullscript here:

$file_name = $_GET['qqfile'];
$uploader = new qqFileUploader($allowedExtensions, $sizeLimit);
$m_id = $row_RecUser['m_id'];
$file_type = $_REQUEST['param1'];

if (strcmp($file_type,'resume') == 0) {
$result = $uploader->handleUpload('uploader/files/resume'); }
else if (strcmp($file_type,'certificates') == 0) {
$result = $uploader->handleUpload('uploader/files/certificates/'); }

    $insertSQL = sprintf("INSERT INTO filefolder (m_id, file_type, file_title) VALUES (%s, %s, %s)",
                    GetSQLValueString($m_id, "int"),
                    GetSQLValueString($file_type, "text"),
                    GetSQLValueString($file_name, "text"));
