Is any html being submitted before the session_start();? is the <?php at the top of the page? [!--quoteo(post=388183:date=Jun 26 2006, 02:39 PM:name=simonsays)--][div class=\'quotetop\']QUOTE(simonsays @ Jun 26 2006, 02:39 PM) [snapback]388183[/snapback][/div][div class=\'quotemain\'][!--quotec--] OK, I just started to rewrite my project using Smarty and I am new to this engine. I have come across a following problem: Here is a php file [code] <? require_once('Smarty.class.php'); $smarty = new Smarty(); $smarty->assign('self', $_SERVER['PHP_SELF']); $smarty -> assign('uid', $_SESSION['uid']); $smarty -> assign('pwd', $_SESSION['pwd']); if (isset($_POST['proceed']) && $_POST['proceed']=='yes') {$smarty -> assign('proceed', $_POST['proceed']);} $i=2001; while($i>=1920) { $years[]=$i; $i--; } $smarty->assign('years', $years); session_start(); $random = substr(md5(time()),0,6); $_SESSION['random']=$random; echo "Session is ". $_SESSION['random']; $smarty->display('reg.tpl'); ?> [/code] it does some minor routine, but the thing that interests me the most is the spot where it creates session. Echo that I use for control displays session contents perfectly. That session ($_SESSION['random']) is used later in the image.php script: [code]<?php $text = $_SESSION['random']; header("Content-type: image/png"); $im = @imagecreate(65, 27) or die("Cannot Initialize new GD image stream"); $background_color = imagecolorallocate($im, 255, 153, 0); $text_color = imagecolorallocate($im, 255, 255, 255); imagestring($im, 5, 5, 5, $text, $text_color); imagepng($im); imagedestroy($im); ?> [/code] and there is a spot in .tpl file responsible for displaying it (<img src='image.php'>) The problem is that the image is blank (no string in it) and when I click 'submit' the registration validation script also gives error that session is empty. What's wrong? Thanks in advance! [/quote]
