Bonsoir ,

j´ai réaliser un panier et je souhaiterai bloquer l´accés au bouton "Acheter" si l´utilisateur ne choisis pas les frais de ports.

je suppose qu´il faudrait un IF ( si utilisateur ne $_POST ('port') )

alors ... et c´est la ou je bloque je pourrai faire un echo et afficher un message du genre n´oublier pas de choisir les frais de ports ´)

mais comment bloquer le bouton submit qui conduit sur ma page de paiement ???

Voici mon code panier

<?php endforeach; ?>
			<FORM action="panierclass.php" method="post"><?php echo _("Estimation des frais de ports") ?> :
    			<SELECT name="port" size="1">
    			<OPTION value= 2.64><?php echo _("France + 2,64€") ?>
    			<OPTION value = 5.50><?php echo _("Union Européenne + 5,50€") ?>
    			<OPTION value= 5.50><?php echo _("International + 5,50€") ?>
    			</SELECT>
    			<input type="submit" value="<?php echo _("validez") ?>">
    			</FORM>
    			
			<div class="rowtotal">
				<?php echo _("Grand Total") ?> : <span class="total"><?= number_format($panier->total() * 1,2,',',' '); ?> € </span>
			</div>
			<input type="submit" value="Recalculer">
		</div>
	</div>
	</form>
	<form action="../payer.php">
         <button type="submit"><?php echo _("Acheter") ?></button>

et voici la classe de mon panier ou j´ai les variables et la construction

<?php
class panier{

	private $DB;

	public function __construct($DB){
		if(!isset($_SESSION)){
			session_start();
		}
		if (empty($_SESSION['port'])) {
			$_SESSION['port']= 0;
		}
		if(isset($_POST['port'])){
			$_SESSION['port'] = $_POST['port'];
		}
		if(!isset($_SESSION['panier'])){
			$_SESSION['panier'] = array();
		}
		$this->DB = $DB;

		if(isset($_GET['delPanier'])){
			$this->del($_GET['delPanier']);
		}
		if(isset($_POST['panier']['quantity'])){
			$this->recalc();
		}
	}

	public function recalc(){
		foreach($_SESSION['panier'] as $product_id => $quantity){
			if(isset($_POST['panier']['quantity'][$product_id])){
				$_SESSION['panier'][$product_id] = 1;
			}
		}
	}

	public function count(){
		return array_sum($_SESSION['panier']);
	}

	public function total(){
		$total = 0;
		$ids = array_keys($_SESSION['panier']);
		if(empty($ids)){
			$products = array();
		}else{
			$products = $this->DB->query('SELECT id, price FROM products WHERE id IN ('.implode(',',$ids).')');
		}
		foreach( $products as $product ) {
			$total += $product->price * $_SESSION['panier'][$product->id];
		}
		if ($total > 50) {
			$_SESSION['port']= 0;
		}
		return $total + $_SESSION['port'];
	}

	public function add($product_id){
        if(isset($_SESSION['panier'][$product_id])){
            $_SESSION['panier'][$product_id]++;
        }else{
            $_SESSION['panier'][$product_id] = 1;
        }
    }

	public function del($product_id){
		unset($_SESSION['panier'][$product_id]);
	}

}
