            <div class="controls">
                <input class="input-file uniform_on" id="media[]" name="media[]" type="file">
            </div>

        if($media1=="")
        {

Answer 1

Add enctype='multipart/form-data' in your form.

<form class="form-horizontal" method="post" action="gallery.php" enctype='multipart/form-data'>

See this link

Edit:

$filename = "gallery";

if (is_dir($filename))
{
    $filename .= "/" . $_FILES["media"]["name"][$i];
    move_uploaded_file($_FILES["media"]["tmp_name"][$i], $filename);
}
else
{
    if(mkdir($filename))
    {
        $filename .= "/" . $_FILES["media"]["name"][$i];
        move_uploaded_file($_FILES["media"]["tmp_name"][$i], $filename);
    }

}

Answer 2

Add enctype='multipart/form-data' in your form.

<form class="form-horizontal" method="post" action="gallery.php" enctype='multipart/form-data>

Also check $filename = ("gallery");.. seems to be wrong value assign to $filename
