Doublon fichiers uploadés

j'utilise un script d'Upload de fichiers Multique qui lorsque des fichiers de même nom sont déjà présent sur le serveur renomme automatiquement les fichiers à uploader de la façon suivante:

fichier(1).ext
fichier(2).ext
fichier(3).ext

Code:

Quelqu'un peut-il m'aider?
Merci

Qu'entends-tu pas reproduire le code ?

en fait j'essaie de créer un script d'upload de fichier image et j'y arrive si je renomme le fichier systématiquement avant de l'envoyer sur le serveur. Je voudrais pouvoir conserver le nom initial du fichier et le renommer fichier(1).ext si par hasard il existait une version sur le serveur au lieu de remplacer le fichier existant.

Je ne souhaite pas reproduire le code complet mais juste le fait de pouvoir vérifier les noms de fichier existant sur le serveur pour pouvoir adapter le nom du fichier avant l'upload ex: fichier(1).ext, fichier(2).ext, fichier(3).ext etc...

Quelque chose comme ça (j'ai mis le nom du fichier à la main pour l'exemple)

Code:

---

1 2 3 4 5 6 7 8 9 10

$path = "tonchemin"; $fichier = "fichier"; $ext = "ext"; $new_name = $fichier; $x = 0; while (is_file($path . "/" . $new_name . "." . $ext)) { ++$x; $new_name = $fichier . '(' . $x . ')'; } echo $new_name . '.' . $ext;

Salut,

La ligne 425 ne contient qu'un bout de code nécessaire au renommage des fichiers. Le fonctionnement total est réparti sur plusieurs fonctions.

Voici une fonction de renommage "autonome" :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51

function Rename_fich($adresse_fichier, $incr = false, $unix = false, $stop = 0) { if (is_file($adresse_fichier)) { $info = pathinfo($adresse_fichier); $extension = isset($info['extension']) && $info['extension'] != '' ? '.'.$info['extension'] : null; $dossier = $info['dirname']; $filename = $info['filename'];   if (trim($incr) != false && $stop < 90) { $file = addcslashes($filename,'.'); $ext = isset($extension) ? addcslashes($extension,'.') : null;   $match = $unix ? '#^'.$file.'_[0-9]+'.$ext.'$#' : '#^'.$file.'_[0-9]+'.$ext.'$#i';   $tab_identique = array();   $files = new RegexIterator(new DirectoryIterator($dossier),$match); foreach ($files as $fileinfo) $tab_identique[] = $fileinfo->getFilename();   natsort($tab_identique);   $dernier = array_pop($tab_identique);   unset($tab_identique);   $dernier = isset($dernier)? pathinfo($dernier, PATHINFO_FILENAME) : '';   $file = preg_replace_callback('#([0-9]+$)#', create_function('$matches','return $matches[1]+1;'), $dernier, '1', $count);   $filename = !empty($count)? $file : $filename.'_1'; } else { $filename .= '_'.uniqid(); }   $filename = isset($extension) ? $filename.$extension : $filename;   $adresse = $dossier.'/'.$filename;   if (!is_file($adresse)) return $adresse; else return $this->Rename_fich($adresse_fichier, $incr, $unix, ++$stop); } else { return $adresse_fichier; } }

Cette fonction est intégrée dans cette classe d'upload mais tu peux l'utiliser séparément.

Il suffit d'indiquer l'adresse de destination du fichier (dossier/fichier.ext) comme premier paramètre et d'indiquer "true" comme deuxième paramètre ce qui initie la fonction d'incrémentation. En retour tu as le nouveau nom renommé en cas de doublon sur le serveur.
Par exemple :

Code:

---

1 2	$nom = Rename_fich('PHOTOS/toto.jpg', true); echo $nom;

---

Si tu télécharge un fichier nommé "toto.jpg" dans le dossier "PHOTOS" qui comprend déjà un fichier du même nom, la fonction retournera "PHOTOS/toto_1.jpg", puis "PHOTOS/toto_2.jpg", puis "PHOTOS/toto_3.jpg" etc. C'est pas exactement le format que tu recherche mais le principe est le même et tu pourrais adapter le code.

Après je me demande un peu pourquoi tu veux faire une classe d'upload si tu en utilise une qui fonctionne ? Ou que voudrais-tu en plus ? Je dis cela parce que c'est moins simple qu'il n'y paraît au premier abord, notamment en plus du renommage il faut aussi gérer les erreurs de dépassement de configuration serveur (ce qui peut arriver assez vite avec l'upload multiple) sinon tu pourrais te retrouver devant une page vide. Sans compter l'intégration d'autres fonctions si tu veux faire des redimensionnements à la volée par exemple.
Si besoin tu trouveras deux classes d'upload (chacune fournies dans un dossier de test prêt à l'emploi et doc en français) en suivant les liens de mon ardoise http://www.developpez.net/forums/ima...-uploadeur.png sous mon nom.

Merci pour ce script qui fonctionne parfaitement.
Voici quelques précisions pour répondre à vos interrogations.
En fait j'utilise une version de ce script pour effectuer un upload de "masse" dans une galerie de photos, et j'ai développé un script permettant de remplacer une image ou d'insérer des informations textes s'y rattachant dans une bdd (titre, commentaire...) de façon individuelle. Mon soucis alors est le risque d'écraser une image différente de celle que je modifie réellement si un même nom est déjà présent sur le serveur, d'où mon post.

Concernant le timeout du serveur j'ai testé l'upload multiple avec une dizaine de photos de près de 5 Mo chacune, c'est long mais cela a parfaitement fonctionné.

Merci pour votre aide.

J'ai modifier une partie du code pour l'adapter à mon format de nom. Cela fonctionne mais j'ai un doute sur la "normalité" de la chose (J'ai l'impression d'avoir fait du "bidouillage":?) Est-ce correct ?

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

//$match = $unix ? '#^'.$file.'_[0-9]+'.$ext.'$#' : '#^'.$file.'_[0-9]+'.$ext.'$#i'; $match = $unix ? '#^'.$file.'\([0-9]+\)'.$ext.'$#' : '#^'.$file.'\([0-9]+\)'.$ext.'$#i';   $tab_identique = array();   $files = new RegexIterator(new DirectoryIterator($dossier),$match); foreach ($files as $fileinfo) $tab_identique[] = $fileinfo->getFilename();   natsort($tab_identique);   $dernier = array_pop($tab_identique);   unset($tab_identique);   $dernier = isset($dernier)? pathinfo($dernier, PATHINFO_FILENAME) : '';   //$file = preg_replace_callback('#([0-9]+$)#', create_function('$matches','return $matches[1]+1;'), $dernier, '1', $count); $file = preg_replace_callback('#([0-9]+\)$)#', create_function('$matches','return $matches[1]+1;'), $dernier, '1', $count);   //$filename = !empty($count)? $file : $filename.'_1'; $filename = !empty($count)? $file.')' : $filename.'(1)'; } else { //$filename .= '_'.uniqid(); $filename .= '('.uniqid().')'; }
