Redimensionnement "à l'affichage"

27 avr. 2011, 18:21

Bonjour,
je souhaite redimensionner à l'affichage des photos qui sont uploadées dans une base de données en taille 460x352 aussi bien les chats que sur les chatons voir page exemple : http://www.chats-persans.com/_fr/fiche. ... d_chat=236 ou bien alors je souhaite que les photos soit redimensionnées lors de l'upload.
Merci pour votre aide.

Voici le code ma page ou les photos s'affichent :

Code : Tout sélectionner

<?php
header('Content-Type: text/html; charset=utf-8');

include "../admin/image.class.php";

if(!isset($_GET['lg'])) $_GLOBAL['lg'] = 'fr';
else $_GLOBAL['lg'] = $_GET['lg'];

include 'php/mysql.inc.php';
include_once '../php/chatterie.inc.php';

$fiche = fiche($_GET['id']);
$id = $_GET['id'];
 $requete = "
   SELECT id_chats, type_chats, img_ronde, img_carre, nom_chats, desc_chats, race_chats, dispo_chats, pere_chats, mere_chats, ligne_chats,  sexe_chats, place
   FROM adh_chats
   WHERE id_chatterie = '".$id."'
   ORDER BY place DESC";
   $result = mysql_query($requete);
   $m = 0;
   $f = 0;
  $c = 0;
   while ($tab = mysql_fetch_array($result)):
     //print_r($tab);
     if(!isset($_GET['id_chat']) AND !isset($details_c)) $details_c = @getimagesize("../upimages/".$tab['img_carre']);
     if(!isset($_GET['id_chat']) AND !isset($file_c)) $file_c = "../upimages/".$tab['img_carre'];
     if(!isset($_GET['id_chat']) AND !isset($nom)) $nom = utf8_encode($tab['nom_chats']);
     if(!isset($_GET['id_chat']) AND !isset($desc)) $desc = utf8_encode($tab['race_chats']);
     
     if($tab['type_chats'] != 3)
      $file = "../upimages/".$tab['img_ronde'];
    else
      $file = "../upimages/".$tab['img_carre'];
     
     $details = @getimagesize($file);

C'est plus efficace de les redimensionner lors de l'upload car les pages s'afficheront plus vite et cela soulagera le serveur.
Une classe d'upload de fichiers qui peut faire du redimensionnement d'images ici (en plusieurs dimensions si besoin).

Bonsoir,
un peu d'aide s'il vous plait car ce n'est pas moi qui ai fait le code et je ne comprends pas comment gérer les photos uploadées.
Merci.
