Bonjour,

J'essaye de mettre en place un formulaire de contact sur mon site. Chaque champ est vérifié via AJAX : ça, ça marche.

Le script que j'ai pris est censé marcher aussi avec ou sans javascript.

Tout marche, mis à part le fait que le mail n'est pas envoyé, et ce, aussi bien avec ou sans javascript d'activé !

Le problème vient donc forcément du fichier PHP qui effectue le traitement du formulaire. Seulement je n'arrive pas à voir d'où vient l'erreur...

Voici le fichier :

Est ce que quelqu'un peut me dire d'où vient l'erreur ? Vous pouvez voir le formulaire en action à cette adresse :
http://www.lambda-comm.fr/test/contact.php.

Si vous voulez voir l'erreur PHP, il faut désactiver Javascript sur votre navigateur.

J'espère que quelqu'un aura le courage de lire mon sujet

Bonjour,
J'essaye de mettre en place un formulaire de contact sur mon site. Chaque champ est vérifié via AJAX : ça, ça marche.
Le script que j'ai pris est censé marcher aussi avec ou sans javascript.
.........

J'espère que quelqu'un aura le courage de lire mon sujet

Oui oui, pour moi surtout deux erreurs,
en premier le GET n'est pas toujours présent, alors a la ligne 332 tu derais avoir un truc comme cela au lieu de

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
 
if ( $_GET['contact'] == true && $_GET['xml'] == true ) 
{

Mets,

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

if (isset($_GET["contact"])) $val1=trim($_GET["contact"]);
    else $val1="Non";
if (isset($_GET["xml"])) $val2=trim($_GET["xml"]);
    else $val2="Non";
if ($val1!='Non' && $val2!='Non' )
{

voila une erreur en moins, quand a la variable "posStatus"

Elle n'est valorisée que dans un IF !!
donc si le if n' est pas exécuté cette variable n'existe pas !
et en ligne 346 tu as une erreur !!

Alors au début de ton PHP mets

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

$posStatus="";

Merci beaucoup pour ta réponse.

Seulement, j'ai toujours le même problème : le mail ne part pas

Cela m'affiche l'erreur suivante :

Erreur ( Impossible d'envoyer le message, veuillez réessayer ultérieurement )

Veuillez revenir à la page précédente pour corriger vos erreurs.

A mon avis, ça doit forcément venir de la ligne qui utilise la fonction mail()... Mais pourtant, les paramètres me semblent corrects !

Une idée ?

Tu as surtout depuis le début,

"Pos.responseXML.document.Elements" valeur null ou n'est pas un objet !!

[freak999]

Pourrais-tu m'expliquer cela ? Et comment résoudre le problème ?

Je t'en remercie

[freak999]

Maintenant, mon formulaire marche si je n'active pas javascript, j'avais juste fait une erreur de syntaxe pour le mail de destination, c'était :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

$recipients = "onerecip|contact@lambda-comm.fr";

Au lieu de :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
 
$recipients = "onerecip|(contact@lambda-comm.fr)";

Par contre, l'envoi en Ajax ne fonctionne pas... L'erreur doit venir de ce que tu disais (pos.responseXML....).

Je ne sais pas comment arranger le problème

Voici le .js si cela peut t'encourager à m'aider :

[FoxLeRenard]

Maintenant, mon formulaire marche si je n'active pas javascript, j'avais juste fait une erreur de syntaxe pour le mail de destination, c'était :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

$recipients = "onerecip|contact@lambda-comm.fr";

Au lieu de :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
 
$recipients = "onerecip|(contact@lambda-comm.fr)";

Par contre, l'envoi en Ajax ne fonctionne pas... L'erreur doit venir de ce que tu disais (pos.responseXML....).

Je ne sais pas comment arranger le problème

Voici le .js si cela peut t'encourager à m'aider :

J'espère que ça ne t'embête pas de regarder Merci en tout cas de t'en soucier

Oui bien sur mais alors là, AJAX connais pas du tout !!

Maintenant que le probléme est mieux cerné, je te conseilles avec tes derniéres versions et surtout un copié collé du message d' erreur, de relancer un nouveau fil dont le sujet commencerait par
"AJAX" etc ............. comme ça tu aura les spécialistes en ligne !!

[freak999]

Ok merci beaucoup d'avoir regardé mon problème.

A bientôt (sans doute )
