Contrôler la taille de l'image avant l'upload

[trustno1]

bonjour,
Voici le fichier d'upload que j'ai testé :

<?


class Upload {
    var $up_file;
	var $f;
    var $p;
	var $name;
	var $size;

	var $path;

	var $errors;
	var $move;
	
	function Upload($input_name,$size,$width,$height,$dir) {
	    $this->f = $input_name;
		$this->max_size = $size;
		$this->directory = $dir;
		$this->max_width = $width;
		$this->max_height = $height;
	}
	
  function do_upload() {
  //global $_FILES;
	    $this->up_file = $_FILES[$this->f]['tmp_name'];
		$this->name = $_FILES[$this->f]['name'];

quand j'essai d'uploader un image, le fichier ne contrôle pas la taille de l'image (size).
J'ai fixé le size à 30 ko, et il upload les images < = 30 ko mais il ne donne pas d'alertes quand l'image est >=30 ko.

Merci pour votre aide

Salut trustno1

$my_max_file_size = "30000"; //en octets
// controle poids :
if ($_FILES['the_file']['size'] > $my_max_file_size )
{


{echo "<font size=\"2\" color=\"#FF0000\">Votre image a une taille de ".sprintf("%01.3f", ($_FILES['the_file']['size']/1000000))." Mega Octets. <br>La taille maximum autorisée est de ".($my_max_file_size / 1000000)." Mega Octets.<br><br><a href=\"javascript:window.history.back()\">Retour</font></a>";exit;}
}

Voila, moi j'utilise ca pour controler le poids des fichiers uploadé
