Bon voici le code que j'ai utilisé pour le formulaire.
Le formulaire est affiché et tout mais quand je valide,l'enregistrement ne figure pas dans la base de données.
<?php
/*recuperation des valeurs du formulaire*/
$numero=@$HTTP_POST_VARS['numero'];
$nom=@$HTTP_POST_VARS['nom'];
$type=@$HTTP_POST_VARS['type'];
$projet=@$HTTP_POST_VARS['projet'];
$PU=@$HTTP_POST_VARS['PU'];
$quantite=@$HTTP_POST_VARS['quantite'];
$amortissable=@$HTTP_POST_VARS['amortissable'];
$duree_amort=@$HTTP_POST_VARS['duree_amort'];
$periode=@$HTTP_POST_VARS['periode'];
/*permettre la saisie des caracteres particuliers*/
$numero=htmlentities($numero,ENT_QUOTES);
$nom=htmlentities($nom,ENT_QUOTES);
$type=htmlentities($type,ENT_QUOTES);
$projet=htmlentities($projet,ENT_QUOTES);
$PU=htmlentities($PU,ENT_QUOTES);
$quantite=htmlentities($quantite,ENT_QUOTES);
$amortissable=htmlentities($amortissable,ENT_QUOTES);
$duree_amort=htmlentities($duree_amort,ENT_QUOTES);
$periode=htmlentities($periode,ENT_QUOTES);
/* connexion*/
$connect = mysql_connect('localhost','root','') or die ("erreur de connexion");
$base="finance";
mysql_select_db($base,$connect) or die ("erreur de connexion base");
$req= "INSERT INTO produit (numero,nom,type,projet,PU,quantite,amortissable,duree_amort,periode) VALUES ('$numero','$nom','$type','$projet','$PU','$quantite','$amortissable','$duree_amort','$periode')";
$result = mysql_query($req) or die(mysql_error());
/*fermeture de la connexion*/
mysql_close($connect);
