Ayuda con SWFUPLOAD "application" El codigo que estoy utilizando es este. Subiendo estos ficheros al servidor funciona pero solo en IE y no en Firefox (Cuando en la web de Swfupload si que funciona. link)
Lo que quiero hacer es que me suba un conjunto de imágenes para que después meterlas en BD para crear una galería pero no se que código meter en PHP para que realice esa tarea.
Los códigos son los siguientes:
index.php
Código HTML:
<?php session_start(); $_SESSION["file_info"] = array(); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title>SWFUpload Demos - Application Demo</title> <link href="css/default.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="swfupload/swfupload.js"></script> <script type="text/javascript" src="js/handlers.js"></script> <script type="text/javascript"> var swfu; window.onload = function () { swfu = new SWFUpload({ // Backend Settings upload_url: "upload.php", // Relative to the SWF file post_params: {"PHPSESSID": "<?php echo session_id(); ?>"}, // File Upload Settings file_size_limit : "2048", // 2MB file_types : "*.jpg", file_types_description : "JPG Images", file_upload_limit : "0", // Event Handler Settings - these functions as defined in Handlers.js // The handlers are not part of SWFUpload but are part of my website and control how // my website reacts to the SWFUpload events. file_queue_error_handler : fileQueueError, file_dialog_complete_handler : fileDialogComplete, upload_progress_handler : uploadProgress, upload_error_handler : uploadError, upload_success_handler : uploadSuccess, upload_complete_handler : uploadComplete, // Flash Settings flash_url : "swfupload/swfupload_f9.swf", // Relative to this file custom_settings : { upload_target : "divFileProgressContainer" }, // Debug Settings debug: false }); }; </script> </head> <body> <div id="header"> <h1 id="logo"><a href="../">SWFUpload</a></h1> <div id="version">v2.1.0</div> </div> <div id="content"> <h2>Application Demo</h2> <p>This demo shows how SWFUpload can behave like an AJAX application.

Código PHP:
<?php
/* Note: This thumbnail creation script requires the GD PHP Extension.
If GD is not installed correctly PHP does not render this page correctly
and SWFUpload will get "stuck" never calling uploadSuccess or uploadError
*/
