Bonjour,
vous avez dis que vous vouliez supprimer un enregistrement, mais je ne vois nulle part la requête de suppression. Montre nous ta requête pour voir.
J'ai remarqué certaines erreurs sur ta page.
- Quand tu utilise do while, je crois que la valeur ?code= dans la première ligne affiché sera vide, n'est ce pas?
- Il faut séparer echo et $row_rs_enseig['code']; met
  
  Code:
  
  echo $row_rs_enseig['code'];
  
  au lieu de
  
  Code:
  
  echo$row_rs_enseig['code'];
je ne sais pas est ce que ce sont vraiment des erreurs? dis le moi si je me trompe.

T'as dis que tu veux passer par une page de validation appelé "supprimer.php" mais ce que je vois là c'est que tu passe directement vers la page "supprimer_enseignant.php"

Code:

<td><div align="center"><a href="supprimer_enseignant.php?code=<?php echo$row_rs_enseig['code'];?>">Supprimer</a></div></td>

Essai

Code:

<td><div align="center"><a href="supprimer.php?code=<?php echo$row_rs_enseig['code'];?>">Supprimer</a></div></td>

Bonsoir,
Il faut que tu nous montre le code des trois pages. Par ce que comme je t'ai dis en haut je ne vois nulle part la requête de suppression. Et je crois que tu te trompe entre les deux pages, supprimer.php et supprimer_enseignant.php. Je suis presque sûr que la page supprimer.php c'est celle de confirmation et supprimer_enseignant.php et celle qui supprime.

le code de la page modifier_supprimer_enseigant est

il est dans la 2 éme page

Je crois que j'ai découvert le problème.
Dans la page 'modifier_supprimer.php' voici le code que tu as mis:
Code:

1 2 3 <td><div align="center"><a href="supprimer_enseignant.php?code=<?php echo$row_rs_enseig['code'];?>">Supprimer</a></div></td> </tr>
Donc tu envoi à la page supprimer_enseignant.php le code de l'enseignant par la méthode GET.Jusqu'à maintenant c bon.

Mais regarde ce que tu fais tout en haut dans la page 'supprimer_enseignant.php':
Code:

1 2 3 4 5 6 if ((isset($_GET['code'])) && ($_GET['code'] != "")) { $deleteSQL = sprintf("DELETE FROM enseignant WHERE code=%s", GetSQLValueString($_GET['code'], "int")); mysql_select_db($database_informatique, $informatique); $Result1 = mysql_query($deleteSQL, $informatique) or die(mysql_error());
C'est évident que la requête de suppression sera exécutée sans confirmation. Ce n'est qu'une petite faute, il fallait que tu met $_POST au lieu de $_GET:
Code:

1 2 3 4 if ((isset($_POST['code'])) && ($_POST['code'] != "")) { $deleteSQL = sprintf("DELETE FROM enseignant WHERE code=%s", GetSQLValueString($_GET['code'], "int"));
je crois que ça va marcher comme ça. Mais avant il faut que tu modifie encore ton code. Il faut que tu encadre ton tableau avec le formulaire, car si non les inputs que tu as mis hors du formulaire ne seront pas transmis.
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 <form id="form1" name="form1" method="post" action=""> <table width="260" height="113" align="center"> <tr valign="baseline"> <td width="43" align="right" nowrap="nowrap">Code:</td> <td width="195"><input type="text" name="code" value="<?php echo $row_rs_enseig['code']; ?>" size="32" /></td> </tr> <tr valign="baseline"> <td height="47" align="right" nowrap="nowrap">Nom:</td> <td><input type="text" name="nom" value="<?php echo htmlentities($row_rs_enseig['nom'], ENT_COMPAT, 'utf-8'); ?>" size="32" /></td> </tr> </table> <label> <input type="submit" value="supprimer" /> </label> </form
