Update from a foreach

Hello,

I have a little trouble updating my table from a loop.
Here is my html, my update code and finally my print_r($ _POST);

No update is done, I need your help please.

<form method="POST" action="_editer_produit.php" id="Form" name="Form">

<button type="submit" name="Editer_Libelle" id="Editer_Libelle" >Edit</button>

<?php try{$Stat = $pdo->query("SELECT * FROM tb_produits_test ORDER BY Libelle_FR"); $i = 0; while($data = $Stat->fetch(PDO::FETCH_ASSOC)){ ?>

<input type="hidden" name="NumId_AA[<?php echo $i;?>]" id="NumId_AA_<?php echo $i;?>" value="<?php echo $data["NumId"]; ?>">

<input type="text" id="Libelle_FR_<?php echo $i;?>" name="Libelle_FR[<?php echo $i;?>]" value="<?php echo $data["Libelle_FR"]; ?>">
<input type="text" id="Libelle_AR_<?php echo $i;?>" name="Libelle_AR[<?php echo $i;?>]" value="<?php echo $data["Libelle_AR"]; ?>">

<?php $i++; }}catch(PDOException $e){echo "<div class='alert alert-danger'>".$e->getMessage()."</div>";} ?>

</form>

Select allOpen in new window

if(isset($_POST['Num_AA'])) {

$Num_AA = !empty($_POST['Num_AA']) ? $_POST['Num_AA'] : array();
$LIB_FR = !empty($_POST['LIB_FR']) ? $_POST['LIB_FR'] : array();
$LIB_AR = !empty($_POST['LIB_AR']) ? $_POST['LIB_AR'] : array();

try{
$UPD = $pdo->prepare("UPDATE tb_produits_test SET Libelle_FR=:LIB_FR, Libelle_AR=:LIB_AR WHERE NumId=:Num_AA ");

foreach($LIB_FR as $key => $value){
$UPD->bindParam(":LIB_FR", 	$value);
$UPD->bindParam(":LIB_AR", 	$LIB_AR[$key]);
$UPD->execute();
}

}catch(PDOException $e){echo "<div class='alert alert-warning'>".$e->getMessage()."</div>"; die();}
}
