PHP application SWFUpload Upload questions about the session
SWFUpload in the upload to reopen a new session process, can not be consistent with the original program session, need to upload the original program to pass the SessionID, according to it to "retrieve" its due session
But I can't find anything. Any friends know, help. Thank you, sir. I'm using the DEDECMS program.

This is the seeeion that swfupload in the open.

JScript Code

  
   Upload_url: "upload.php",        post_params: {"PHPSESSID": "
  
    "},        file_size_limit: "2048",        File_ Types: "*.jpeg;*.jpg;*.bmp;*.png;*.gif;*.flv;*.mp4;*.wma",        file_types_description: "Allow upload format",        File_ Upload_limit: "",        File_queue_limit: "0",

This is the information for the upload.php processing page

PHP Code

  
   if (Isset ($_post["PHPSESSID"])) {        session_id ($_post["PHPSESSID"]);    } else if (Isset ($_get["PHPSESSID"])) {        session_id ($_get["Phpsessid");    }    $img _path = '/uploads/';    Session_Start ();
