Upload Multiple Files In PHP

Question

I wonder whether someone may be able to help me please.

Using some excellent online tutorials I\'ve put together the code below which allows a user to upload image files

Answer 1

PHP

foreach($_FILES['image']['name'] as $i => $name)
{
    // now $name holds the original file name
    $tmp_name = $_FILES['image']['tmp_name'][$i];
    $error = $_FILES['image']['error'][$i];
    $size = $_FILES['image']['size'][$i];
    $type = $_FILES['image']['type'][$i];

    if($error === UPLOAD_ERR_OK)
    {
        $extension = getExtension($name);
        if( ! in_array(strtolower($extension, array('jpg', 'jpeg', 'png') )
        {
            // Error, invalid extension detected
        }
        else if ($size > $maxAllowedFileSize /* needs to be defined elsewhere */)
        {
            // Error, file too large
        }
        else
        {
            // No errors
            $newFileName = 'foo'; // You'll probably want something unique for each file.
            if(move_uploaded_file($tmp_file, $newFileName))
            {
                // Uploaded file successfully moved to new location
                $thumbName = 'thumb_image_name';
                $thumb = make_thumb($newFileName, $thumbName, WIDTH, HEIGHT);
            }
        }
    }
}

HTML

<form method="post" enctype="multipart/form-data">
    <input name="image[]" type="file" class="image-upload" />
    <input name="image[]" type="file" class="image-upload" />
    <input name="image[]" type="file" class="image-upload" />
    <input name="image[]" type="file" class="image-upload" />
    <input name="image[]" type="file" class="image-upload" />

    <!-- You need to add more, including a submit button -->
</form>

Note the name of the input elements. The [] at the end cause PHP to create an array and add the items to the array.

If you don't bother paying for it, you may have a look at PHP File Uploader, it's a very nifty and useful tool, that I already used for a couple of sites.
Not that cheap, but definitely worth the cost.
