Problème code esp8266


#1

Bonjour,

je suis en train de poser quelques lignes de code pour envoyer des commande sur un serveur web qui communiquera via le port série avec un arduino pour afficher des messages sur un panneau LED.

Mon code fonctionne avec le input text et le submit dans la foulée mais je ne parvient pas à ajouter d’autres infos dedans
(couleur de led, defilement…)
dès que je rajoute des inputs, j’ai uniquement ma commande text qui apparait et ca me supprime mon bouton de validation.

Si quelu’un à une idée, je suis preneur

Bonjour,

De mémoire il te faut un input name différent pour chaque input, non ?
Il est où ton command.php ?
