Upload in Google Chrome not working - php

Question

I am creating simple file upload (for pictures). I tried in Opera and in FireFox and uploading is working fine. But when I upload via Google Chrome, picture is not uploaded. Can you please tell me where is problem:
here is php script that is used for storing picture in database
<?php
$id=$_SESSION['user_id'];
$user_id=$_SESSION['user_id'];
$album_id=$_POST['album'];
$max_size = 500; // Sets maxim size allowed for the uploaded files, in kilobytes
// sets an array with the file types allowed
$allowtype = array('bmp', 'gif', 'htm', 'html', 'jpg', 'jpeg', 'mp3', 'pdf', 'png', 'rar', 'zip');
// if the folder for upload (defined in $updir) doesn't exist, tries to create it (with CHMOD 0777)
/*if (!is_dir($updir)) mkdir($updir, 0777);*/
/** Loading the files on server **/
$result = array(); // Array to store the results and errors
// if receive a valid file from server
if (isset ($_FILES['files'])) {
// checks the files received for upload
$file_name=$_FILES['files']['name'];
$file_type=$_FILES['files']['type'];
$file_size=$_FILES['files']['size'];
$file_tmp=$_FILES['files']['tmp_name'];
for($f=0; $f<count($_FILES['files']['name']); $f++) {
$file_name = $_FILES['files']['name'][$f];
$random_name=rand();
// checks to not be an empty field (the name of the file to have more then 1 character)
if(strlen($file_name)>1) {
// checks if the file has the extension type allowed
$type=explode('.', $file_name);
$type=end($type);
if (in_array($type, $allowtype)) {
// checks if the file has the size allowed
if ($_FILES['files']['size'][$f]<=$max_size*1000) {
// If there are no errors in the copying process
if ($_FILES['files']['error'][$f]==0) {
$query = mysql_query("SELECT username from users WHERE id = '$id' ");
while($run=mysql_fetch_array($query)){
$username=$run['username'];
}
$query = mysql_query("SELECT album.name an from album WHERE album.id = '$album_id' ");
while($run=mysql_fetch_array($query)){
$album_name=$run['an'];
}
mysql_query("INSERT INTO photos VALUE ('', '$album_id', '$random_name.jpg', '$user_id')");
// Sets the path and the name for the file to be uploaded
// If the file cannot be uploaded, it returns error message
if (move_uploaded_file ($_FILES['files']['tmp_name'][$f],"./users/".$username."/".$album_name."/".$random_name.".jpg")) {
/*$result[$f] = ' The file could not be copied, try again';*/
$result[$f] = '<b>'.$file_name.'</b> - OK';
}
else {
$result[$f] = ' The file could not be copied, try again';
}
}
}
else { $result[$f] = 'The file <b>'. $file_name. '</b> exceeds the maximum allowed size of <i>'. $max_size. 'KB</i>'; }
}
else { $result[$f] = 'File type extension <b>.'. $type. '</b> is not allowed'; }
}
}
// Return the result
$result2 = implode('<br /> ', $result);
echo '<h4>Files uploaded:</h4> '.$result2;
}
?>
and here is form that is used for picture uploading:
<form id="uploadform" action="uploaderimg.php" method="post" enctype="multipart/form-data" target="uploadframe" onSubmit="uploading(this); return false">
<br>
Select album:
<select name="album">
<?php
$query=mysql_query("SELECT id, name, user_id FROM album WHERE user_id = '$id'");
while($run=mysql_fetch_array($query)){
$album_id=$run['id'];
$album_name=$run['name'];
$album_user = $run['user_id'];
echo "<option value='$album_id'>$album_name</option>";
}
?>
</select>
<br /><br />
<h1>Chose your photo/s</h1>
<br>
<input type="file" name="files[]" />
<input type="submit" value="UPLOAD" id="sub" />
</form>
EDIT:
THis is error according to PHP(it's in first script that store uploaded file):
Notice: Undefined index: album in..

Answer 1

After conversing with the OP, the problem lay in this line:
<form id="uploadform" action="uploaderimg.php" method="post" enctype="multipart/form-data" target="uploadframe" onSubmit="uploading(this); return false">
Where onSubmit="uploading(this); return false" was at fault.
