Re: [Résolu] Ajout de catégories d'une galerie dans une autre.

Le piwigo maître est dans quelle version?
Les fichiers à prendre sont dans le répertoire ./tools de la version du site maître.

Et à placer das le cas présent dans le répertoire ./galleries/ du site distant.

PS: Là le site distant est lui aussi une galerie Piwigo mais ce n'est pas nécessaire.

Re: [Résolu] Ajout de catégories d'une galerie dans une autre.

Je me résume:
La galerie Perso possède la catégorie en FTP, je souhaite afficher cette dernière dans ma galerie potes.
Je vais donc prendre les fichiers de toos "perso" et les mettre dans galerie. Je vos tiens au jus

Re: [Résolu] Ajout de catégories d'une galerie dans une autre.

Celle qui contient les images c'est le site distant, celles qui va les afficher c'est la galerie maître.
C'est sur la galerie maître qu'on fera la synchro à partir du listing.
Le listing doit être fabriqué par le create_listing_file (CLF) de la même version que la synchro.

Re: [Résolu] Ajout de catégories d'une galerie dans une autre.

Voila ce que j'ai fais:
Les 2fichiers de tools de ma galerie Potes dans "galleries" qui est mon site distant.
Je crée le listing.
Je prend le listing et le remet dans "piwigo" de ma galerie pote qui est mon site maitre.
Mais la je retombe sur le probleme de version.

Allez vais me coucher fais vraiment trop chaud en Alsace verrait ça demain matin avec vous.

Re: [Résolu] Ajout de catégories d'une galerie dans une autre.

Copie/colle le contenu de create_listing_file_local.inc.php

Il y a des choses à changer.

Copie/Colle la première ligne de listing.xml (change le nom du site au besoin).

Cela sera peut-être plus clair pour les explications à venir.





PS:  À propos de "Potes" utilise, stp, le terme de "site principal" pour tous ceux qui reliront le sujet.

Et voila le listing généré sur la galerie distante

<dir0 name="12.06.2010Corse">
  <root>
    <element file="20100627000318-d93ebecc.jpg"

Je me tiendrais à site principal et distant pour la prochaine fois^^

Re: [Résolu] Ajout de catégories d'une galerie dans une autre.

Est-ce que ton site principal est en 2.1.1 ou en 2.1.2 ???



J'ai demandé le Copié/collé du contenu de create_listing_file_local.inc.php
pas celui de create_listing_file.php (celui-ci ne doit pas être modifié !!!)

J'attends donc le Copié/collé du contenu de
create_listing_file_local.inc.php

Merci.

Re: [Résolu] Ajout de catégories d'une galerie dans une autre.

Les deux galeries sont en 2.1.1.
Désolé j'avais mal lu.

Code:

 <?php
// this file is provided as an example.
// Move it to "create_listing_file.php"
// directory if you want to modify default configuration.

// URL of main gallery
// Example : http://www.my.domain/my/directory
$conf['gallery'] = 'http://demo.piwigo.net/';

$conf['file_ext'] = array_merge($conf['file_ext'], array('flv', 'FLV'));

$conf['force_refresh_method'] =  true;

?>

Re: [Résolu] Ajout de catégories d'une galerie dans une autre.

thomorph a écrit:

// URL of main gallery
// Example : http://www.my.domain/my/directory
$conf['gallery'] = 'http://demo.piwigo.net/';

Donc déjà $conf['gallery'] est à corriger.

Mais tu vas ajouter peut-être quelques options (au choix):


$conf['version'] = '2.1.1'; # Il ne faut pas le préciser car c'est le create_listing_file (clf) qui doit le fournir...
// sauf que si je passe ma galerie principale en 2.1.2 le clf n'a peut-être pas besoin d'être modifié
// il aura besoin d'être modifié en 2.2.x (car le modèle de données aura changé).
// Il me suffit donc en général de modifier $conf['version'] dans le clf_local

$conf['prefix_thumbnail'] = 'TN-';
// DOIT ÊTRE LE MÊME QUE SUR LA GALERIE PRINCIPALE

$conf['file_ext'] = array_merge($conf['file_ext'], array('flv', 'FLV'));
// permet d'ajouter des extensions à prendre en charge (videos, pdf, etc...).


$conf['use_exif'] = true;
$conf['use_exif_mapping'] = array(
  'date_creation' => 'DateTimeOriginal'
  );
$conf['use_iptc'] = false;
$conf['use_iptc_mapping'] = array(
  'keywords'        => '2#025',
  'date_creation'   => '2#055',
  'author'          => '2#122',
  'name'            => '2#005',
  'comment'         => '2#120');
// Les mêmes que sur la galerie en théorie


$conf['protect'] = false;
// Ajouter des index.htm dans les répertoires du site distant pour bloquer les curieux

$conf['protect_warnings'] = true;
// Voir les messages d'erreur

$conf['thumbnail'] = false;
// générer les miniatures (l'extension GD ou GD 2 de PHP doit être activée sur le site distant)

$conf['thumbnail_method'] = 'ratio';
// Méthode de génération :
// - fixed (width et height obligatoire);
// - width (width obligatoire);
// - height (height obligatoire);
// - ratio (ratio obligatoire)
// - exif (tous les paramètres sont facultatifs)

$conf['thumbnail_height'] = 128; # > 0
$conf['thumbnail_width'] = 128; # > 0
$conf['thumbnail_ratio'] = 0.2; # par rapport à l'image en taille web

$conf['thumbnail_format'] = 'jpeg'; # format de la miniature jpeg, png or gif




et les plus méconnus des paramètres:
// ****** Directory mapping ****** //
// directories names
$conf['thumbs'] = 'thumbnail'; // nom du répertoire de miniatures
$conf['high'] = 'pwg_high'; // nom du répertoire de la HD
$conf['represent'] = 'pwg_representative'; // nom du répertoire de representatives
// (90% des utilisateurs ne savent pas à quoi ça sert mais c'est modifiable)


Ton pb est surtout dans $conf['gallery'] = 'http://demo.piwigo.net/';
qui est à corriger.

Re: [Résolu] Ajout de catégories d'une galerie dans une autre.

Salut,
De retour jusqu'a samedi alors je vais essayer de règler mon problème avant le départ car ça traine^^

Petit PS avant ma question. J'ai vu ton message de départ Vdigital et je te souhaite bien d'autres plaisir après Piwigo; en te remerciant encore pour les conseils que tu m'apportes, des solutions au problèmes que tu résous. Tu a permis a beaucoup de forumeur d'évoluer dans Piwigo Merci

Sinon pour mon problème quand il veut l'adresse de la galerie c'est /Piwigo ou carrément le chemin qui mène a la galerie a /corse par exemple

Re: [Résolu] Ajout de catégories d'une galerie dans une autre.

Salut,

Pour avoir déjà posté sur ce fil, je peux reprendre le support si tu le souhaites.

Où en est tu exactement sur le site distant et sur le site principal.

Re: [Résolu] Ajout de catégories d'une galerie dans une autre.

Si j'ai bien raccroché les wagons.

Tu as uns site distant chez free à l'adresse http://monsite.free.fr/magalerie ou tu as déposé le fichier create_listing_file.php dans le repertoire magalerie et tu veux renseigner le parametre $conf['gallery'] dans le fichier create_listing_file_local.inc.php.

ce paramètre doit être le chemin complet vers ton site principal.

Si Piwigo est à la racine de ce site principal tu mets http://monsite
Si Piwigo est dans un répertoire de ce site principal tu mets http://monsite/monrepertoire
