Below is a script with basic error handling:
- renames files: 1.gif ... n.gif n - number of the last file
- checks if file exists
- checks mime format
- checks file size
- it handles up to 10 uploads
- displays upload summary (status of each upload + total number of uploaded files)
Enjoy :-)

You can try this modified version of the script:
<?php
if ($_FILES['userfile']) {
//to see the structure that generates PHP for uploaded files with an name ending with[] uncomment the following line:
echo '<pre>'; var_dump($_FILES); echo '</pre>';
$num = 0;
foreach($_FILES['userfile'
if ($size == 0) {
//no or empty file, skip it
continue;
}
$message .= do_upload($id, $upload_dir, $upload_url);
}
++$num;
}
function do_upload($id, $upload_dir, $upload_url) {
static $counter = 1;
$temp_name = $_FILES['userfile'][$id]['
$file_type = $_FILES['userfile'][$id]['
$file_size = $_FILES['userfile'][$id]['
$result = $_FILES['userfile'][$id]['
$file_name = $counter . '.gif';
$file_url = $upload_url.$file_name;
$file_path = $upload_dir.$file_name;
//File Name Check
if ( $file_name =="") {
$message = "Invalid File Name Specified for filei $id.";
return $message;
}
//File Size Check
else if ( $file_size > 500000) {
$message = "The file size is over 500K for file $id.";
return $message;
}
//File Type Check
else if ( $file_type == "text/plain" ) {
$message = "Sorry, You cannot upload any script file" ;
return $message;
}
if (file_exists($file_path)) unlink($file_path);
$result = move_uploaded_file($temp_n
$message = ($result)?"File url <a href=$file_url>$file_url</
h=\"210\">" :
"Somthing is wrong with uploading a file.";
++$counter;
return $message;
}
?>
.....
<form name="uplVoad" id="upload" ENCTYPE="multipart/form-da
<span class="style1">Upload Slideshow Image<br>
</span>
<?php for ($i = 0; $i< 10; ++$i) { ?>File <?=$i?>:
<input type="file" class="userfile" name="userfile[]"><br>
<?php } ?>
<input type="submit" name="upload" value="Upload">
</form>
So the mostimportant thing to know is how the structure of uploaded files will look like if in the form the name is eneded with []
The files will be name from 1 to 10. If a user skips one field for files inbetween the sequence will not ge broken. This is done by the static variable $counter in do_upload as do up_load is only. If one of those files have failed it will be overwritten by the next file.
