[Web] Formulaire POST

[AchilleFraisse]

Bonjour,

Je ne sais pas ce que j'ai fais, mais j'ai 4 sites sur mon réseau local, et sur chacun des sites, lorsque je clique sur envoyer sur un formulaire (post), il m'affiche une page :

Code : Tout sélectionner

The localhost page isn’t working

localhost is currently unable to handle this request.
HTTP ERROR 500

Je ne sais pas pourquoi. Pourtant mon code marche bien.
Quelques chose qui s'est déconfiguré ?

[Fanch]

500 c'est une erreur coté serveur, il faudrait lire les logs du dit serveur pour en savoir plus...

[AchilleFraisse]

Et je les trouves où ? Mon serveur est apache2

[benjarobin]

Ici: /var/log/httpd

[AchilleFraisse]

Voilà les logs, lorsque je tente d'envoyer mon formulaire :

Si je comprend bien, il a l'air de ne pas connaître la fonction mysql_connect().
Bizzare, puisqu'il y a 3 jours, ca marchait nickel...

[benjarobin]

Je ne vois pas comment il y a 3 jours cela pouvait fonctionner... Cette fonction n'existe plus en PHP 7, à moins de ne pas avoir fait de mise à jour régulière...

[AchilleFraisse]

Je viens de la changer avec :

Code : Tout sélectionner

$bdd = new PDO('mysql:host=localhost;dbname=bdd;charset=utf8', 'root', 'password');

Mais ce ne marche toujours pas.

Cela n'a rien à voir avec Arch Linux... La fonction fetch n'existe pas en php...
Je ne sais pas ce que tu attends ici comme aide, surtout que tu ne donnes pas de code source, et que tu donnes toi même la raison du problème... Après pour le corriger tu es le seul à le pouvoir, donc comment veux tu que l'on t'aide. De toute façon ce n'est pas vraiment le bon forum pour ce genre de question/problème

[AchilleFraisse]

Quand tu fait un :

Code : Tout sélectionner

$bdd = new PDO ...
$req = $bdd->query('...');
$data = $req->fetch()

fetch n'existe pas : http://php.net/manual/fr/pdostatement.fetch.php ?

Je pose la question ici, parce que mon site ne marche PLUS sur mon réseau locale, mais marche sur les serveur d'ovh (c'est exactement le même).
Du coup je pense que c'est un problème de Arch de config. Surement quelque chose qui a sauté lors d'une maj. Mais comme il y a des maj toutes les heures sous Arch, ben je ne sais pas ce que c'est.

Voilà du pourquoi je pose ma question ICI .

[benjarobin]

Comme déjà indiqué, Arch Linux utilise php 7, qui est une énorme évolution de php 5 (encore utilisé chez OVH) ! Donc aucun problème de configuration ici, tu utilisais juste du code marqué comme déprécié depuis très longtemps !

Et pour le fetch, l'erreur t'indique que tu essayes d'appeler la fonction fetch sur un boolean. Sans voir le code complet c'est impossible d'aider, ton code est juste invalide !!!
Pour information

PDO::query() retourne un objet PDOStatement, ou FALSE si une erreur survient.

Donc je pense que la fonction query retourne FALSE. ce n'est pas bien de ne pas faire de gestion d'erreur...
Sinon migrer de l'ancienne API de mysql vers l'API PDO n'est pas ce qu'il y a de plus simple, pourquoi ne pas avoir utilisé l'API mysqli ?
