Bonjour,
Voilà je débute en phph et je fais un petit forum, juste un mini-ptojet, mais j'ai un souci.. J'aimerais par exemple que le champ Username soit obligatoire
J'ai trouvé une solution en php mais je comprends pas pourquoi ça ne marche pas :
-------------------------------------------------------------------------------------------
<?php
$username = $_POST['username'];
$password = $_POST['password'];
if(empty($username))
{
print("<center>Le '<b>Name</b>' est vide !</center>");
exit();
}
?>
-------------------------------------------------------------------------------------------
Et aussi.. Question : où dois je positionner dans le code html ?

ok.
J'ai ajouter une condition à la ligne 30 :
Cette condition affiche le formulaire si la variable $_POST['username'] n'existe pas ou si elle est vide.
Et une autre à la ligne 40 :
Cette condition affiche le msg "This field....." si la variable $_POST['username'] existe et vide
voici le code complet, si tu as besoin d'autre chose, n'hésite pas.
J'ai ajouter une condition à la ligne 30 :
if(!isset($_POST['username']) || empty($_POST['username']) )
{?>
// tu mets le code de ton formulaire ici
<?php
} ?>
Cette condition affiche le formulaire si la variable $_POST['username'] n'existe pas ou si elle est vide.
Et une autre à la ligne 40 :
if(isset($_POST['username']) && empty($_POST['username'])){echo "This field cannot be empty !";}
Cette condition affiche le msg "This field....." si la variable $_POST['username'] existe et vide
voici le code complet, si tu as besoin d'autre chose, n'hésite pas.

Vous n’avez pas trouvé la réponse que vous recherchez ?
Posez votre question
J'aimerais aussi qu'il s'affiche côté du champ username "This field cannot be empty !"
