Multiple file upload

[donutdesign]

Hello,

I just try to upload multiple files into a foloder and make thumbs in other folder.
It's is ok until now, but I need little more filters ,like just jpg format, and a query to insert the name's into mysql db, please help! Thanks

Here is the code:

<?
if(isset($POST['trimis'])){
while(list($nr_poza,$nume_poza) = each($FILES['poze']['name']))
{
if(!empty($nume_poza))
{

					// Valideaza tipul && Marimea mai mica de 0,5 MB
				//	$permise = array('image/jpeg'); echo $permise;
				//	if (!in_array($format, $permise)){
				//		echo "Format nepermis";
				//	}else{

					// Redenumeste poza
					$extensie = explode ('.', $nume_poza);
					$nume_poza = rand() . '.' . $extensie['1']; // Se adauga extensia

					// Muta poza
					$adauga = "imagini/mari/$nume_poza"; // aici copiez pozele mari
					copy($_FILES['poze']['tmp_name'][$nr_poza], $adauga);

					// Redimensionare
					  list($latime, $inaltime) = getimagesize("imagini/mari/".$nume_poza) ; 
					  $poza_mica = imagecreatetruecolor(100, 100) ; 
					  $creaza_poza = imagecreatefromjpeg("imagini/mari/".$nume_poza) ; 
					  imagecopyresampled($poza_mica, $creaza_poza, 0, 0, 0, 0, 100, 100, $latime, $inaltime) ; 
						$adauga = "imagini/mici/" . $nume_poza; //aici copiez pozele mici
					  imagejpeg($poza_mica, $adauga, 100) ; 

					  // Afiseaza imaginea
					  echo "<img src = \"imagini/mici/".$nume_poza."\" />";
					//}//valideaza tipul

			} //end IF
		}// end While

}// end IF trimis

?>
