php - Can't access session variables between 2 files -


i'm unable access session variables session_start() on both files.

file1.php

<?php   session_start();    ...    if($responsecode == 1) {     $_session['card_id']    = $_post['card_id'];     $_session['password']   = $_post['password'];     print '<script type="text/javascript">';      print 'window.location = "http://domain.com/file2.php";';     print '</script>';   } ?>

file2.php

<?php   session_start();    $account = getaccount();    echo "document.write('$account')";    function getaccount() {     $card_id = $_session['card_id'];     $string = "card = " . $card_id ;     return $string;   } ?>

file1.php curl request and, if succeeds, redirects file2.php. however, see card : without card_id entered.

it not work because www considered subdomain, , hence session not persist. can fix in 2 ways -

  1. which consider better way, use htaccess redirect non www urls www urls, better seo

  2. check php manual on how set session across multiple subdomains.

this post explains how www considered subdomain, if curious.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
