JavaScript, DOM et API Web HTML5

Bonjour à tous,

je cherche à implémenter jQuery-File-Upload sur mon site. J'ai donc téléchargé puis uploadé le zip fourni.
Sur la page http://www.pythagorefrance.com/jQuery-File-Upload-9.9.3/index.html , normalement, tout devait marcher.
Cependant, quand je tente d'upolader un fichier, j'obtiens la réponse "server error".
Je suppose que cela correspond à l'erreur
"If uploading files doesn't work, make sure that the php/files directory permissions allow your server write access."
indiquée dans la page d'info sur le setup située ici :
https://github.com/blueimp/jQuery-File-Upload/wiki/Setup

Cependant, je ne comprends pas bien ce message d'erreur. A priori, rien n'interdit l'accès en écriture sur mon serveur. Je pense que c'est vraiment un truc tout bête, mais je ne vois pas lequel. Des idées ?

Le code de ma page :

Je précise qu'après vérification, les fichiers sont correctement upoladés, mais que cela me renvoie quand-même un message d'erreur.
J'ai vu ailleurs quelqu'un suggérant de supprimer le fichier .htaccess du répertoire server/files/php ,
mais cela ne change rien.
Euh....
Ma version de PhP est PHP Version 5.2.8
Je dois en déduire quoi sur la version à télécharger ?
Désolé je me suis mal exprimé, il y a une version master sur git et dans le lien dont je parlais il semblerait qu'il on fait une référence a une version pour PHP.

Pour l'erreur je pense qu'il est possible que tu est mal paramétré le script en question.

Petit question je vois que tu as un fichier main.js et que a l'intérieur tu appel un domain différent est ce normal?

J'ai une erreur 500 dès l'affichage de ta page Smiley decu tu es sur qu'il te manque pas une étape, j'ai pas installé le script par manque de temps.

        // Upload server status check for browsers with CORS support:

                    .appendTo('#fileupload');
            });
        }
Merci pour ta réponse.
Tu as une erreur 500 dès l'ouverture de cette page ?
http://www.pythagorefrance.com/jQuery-File-Upload-9.9.3/index.html
Bizarre, moi pas du tout.
Je pense qu'il est normal de faire référence à //jquery-file-upload.appspot.com , mais je peux me tromper.
En tout cas, les fichiers se téléchargent bien, mais j'obtiens toujours le même message d'erreur. Du coup, l'utilisateur ne peut pas voir sa photo téléchargée ni éventuellement supprimer le fichier puisqu'il a bloqué avant l'affichage du bouton Supprimer
Donc pour l'instant je reste toujours dans le brouillard... Smiley decu
Ben disons je ne connais pas l'outil Smiley decu , mais en ce qui concerne un upload je m'étonne que tu passe par un autre domaine pour faire cette action, le faire sur ton domaine et normal mais qu'un domaine tiers peut intercepter les données me parait bizarre a moins qu'il s'agit d'un server cloud de dépôts de fichier d’où m'a question Smiley decu .

Essaye de la changer pour la faire pointer sur ton domain vers le fichier upload PHP contenue dans le zip du lien UploadHandler.php ou index.php accompagné pour voir...
Modifié par headmax (27 Mar 2015 - 18:40)
Bonjour,

@headmax a raison, tu dois faire pointer l'action de ton form vers /server/php/index.php.
Et attribuer les droits d'écritures sur ton dossier d'upload. Par défaut il me semble que c'est le dossier /server/php/files.
OK,
je viens de remplacer

//jquery-file-upload.appspot.com/


par

server/php/index.php


dans http://www.pythagorefrance.com/jQuery-File-Upload-9.9.3/index.html

et dans http://www.pythagorefrance.com/jQuery-File-Upload-9.9.3/js/main.js

Mais le résultat reste le même. Vous pouvez faire un test avec une image quelconque, si vous le souhaitez.
De plus, Raphi, je ne sais pas comment autoriser l'écriture sur tel ou tel répertoire (je suppose qu'il faudrait que je demande à mon hébergeur). Cependant, je ne pense pas que cela règle le souci, car les images s'enregistrent bien dans le répertoire voulu (ici '../../../espace-enseignants/fichiers/'.$_POST['valeurId']."/" , où $_POST['valeurId'] est une valeur correspondant au répertoire de l'utilisateur, donc ici égale à ''). Il n'y a donc apparemment pas de problème d'écriture, si je ne me trompe pas.

Merci encore pour votre aide.
Bon, finalement,
mon hébergeur a su résoudre le problème, je laisse donc la solution ici, ou plutôt une ébauche de solution. Il fallait modifier le fichier php.ini
Je ne sais pas si cela est lié au fait qu'il s'agit d'un serveur Windows. Je ne sais pas non plus quelles sont les modifications qu'il a effectuées, mais cela permettra peut-être de donner une piste à tous ceux qui rencontreront un problème similaire.
En tout cas, merci à tous ceux qui ont tenté de m'apporter leur aide.
Gilles
