Multiple File upload with dynamic fields - php

Question

Can you please advise/help me with this code? I want to upload multiple files to the server and save the information in database. But this code is uploading only one file, from the first input field.
I have dynamic "upload file" fields, like this:
<form action="uploader.php" method="POST" enctype="multipart/form-data">
<label>Upload</label>
<input type="file" name="file[]">
<label>Description</label>
<input type="text" id="filedesc" name="filedesc[]">
<a href="#" onClick="addUpload('dynamicInputUpload');" >
<img src="../../img/add.png" ></a>
<div id="dynamicInputUpload"></div>
<input type="submit" float= "right" name="add" id="add" value="UPLOAD" >
<input type="hidden" name="pid" id="pid" value="<?php echo $pid; ?>">
<input type="hidden" name="intnumber" id="intnumber" value="<?php echo $int; ?>">
</form>
Bellow is the Javascript that creates dynamic fields:
var counterUpload = 1;
var limit = 10;
function addUpload(divName){
if (counterUpload == limit) {
alert("You have reached the limit of adding " + counterUpload + " inputs");
}
else {
var newdiv = document.createElement('div');
newdiv.innerHTML = " <label>File " + (counterUpload + 1) + "</label><input type=\"file\" name=\"file["+counterUpload+"]\" id=\"file["+counterUpload+"]\"> <label>Description " + (counterUpload + 1) + "</label><input type=\"text\" id=\"filedesc["+counterUpload+"]\" name=\"filedesc["+counterUpload+"]\" >"
document.getElementById(divName).appendChild(newdiv);
counterUpload++;
}
}
And the problem is bellow in the uploader.php. I suceed to uplaod only one (the first) file.

}
}
// File move loop
foreach($_FILES['file']['name'] as $i=> $array_value){
// Get base info
$fileBase = basename($_FILES['file']['name'][$i]);
$fileName = pathinfo($fileBase, PATHINFO_FILENAME);
$fileExt = pathinfo($fileBase, PATHINFO_EXTENSION);
$fileTmp = $_FILES['file']['tmp_name'][$i];
// Construct destination path
$fileDst = $storageDir.'/'.basename($_FILES['file']['name'][$i]);
for ($j = 0; file_exists($fileDst); $j++) {
$fileDst = "$storageDir/$fileName-$j.$fileExt";
}
// Move the file
if (move_uploaded_file($fileTmp, $fileDst)) {
$output[$fileBase] = "Stored $fileBase OK";
$sql=mysql_query("INSERT INTO uploaded_files (pid, file_path,file_type)
Values ('$_POST[pid]','$fileDst','$fileExt')")
or die ("Unable to issue query sql: ".mysql_error());
} else {
$output[$fileBase] = "Failure while uploading $fileBase!";
$errors[$fileBase][] = "Failure: Can't move uploaded file $fileBase!";
}
}
// Handle file move errors here
if (count($errors) > 0) {
die("Errors moving uploaded files: ".print_r($errors, TRUE));
} }

Answer 1

This string has an error:
$sql=mysql_query("INSERT INTO uploaded_files (pid, file_path,file_type)
Values ('$_POST[pid]','$fileDst','$fileExt')")
or die ("Unable to issue query sql: ".mysql_error());
Try to comment this string, your script will save all files.
Maybe you did not connected to the database.
