Bonjour,

pourquoi quand je copie ton code avec isset, le serveur me renvoie "unexpected T_LOGICAL_OR " ?

En fait ca me plaisait bien ce "or", car ca me permettait de dire "si var1 est fixée ou si var2 est fixée, etc...

merci

Bonsoir.

Est-ce que ca ne serait pas plus simple en php ? 
if ((!isset($_POST['case_a_cocher_1'])) or (!isset($_POST[['case_a_cocher_2'])) or (!isset($_POST[['case_a_cocher_3'])))
   echo 'Erreur : vous n\'avez pas rempli tout les champs';

De plus, le JS est un langage client, donc modfiable par l'utilisateur qui peut en faire ce qu'il veut (et /ou le désactiver).

Si tu ne veux pas, je pense que tu pourras facilement adapter ce code en JS, les deux langages ayant une syntaxe très proche ;-)
