lajollaig Posted October 15, 2007 Share Posted October 15, 2007 Hello helpful people! For the record, I am a Newbie in PHP... I found a wonderful Captcha script and it works wonderfully, except when i use include to put it into another file... I get this error message: Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/user/public_html/index.php:12) in /home/user/public_html/securimage.php on line 386 After some short research here it appears that this happens because there is already HTML output in the main page.. I am using the include function to add it (the form) to the regular index.php page.... Do I need to add something in the headers to prevent this? Here is the two relevant scripts: <?php /* This is the contact form I use on my site Feel free to modify it and use it as a guide to setting up securimage for your site. */ $to = "email@email.com"; if (!isset($_POST['submit'])) { showForm(); } else { //form submitted $error = 0; if(empty($_POST['name'])) { $error = 1; $errstr[] = "Please enter a name"; } if(!preg_match("/^(?:[\w\d]+\.?)+@(??:[\w\d]\-?)+\.)+\w{2,4}$/", $_POST['email'])) { $error = 1; $errstr[] = "Please enter a valid email address"; } if (!preg_match("/^[0-9]{3}[-][0-9]{3}[-]{1,1}[0-9]{4}$/", $_POST['phone'])){ $error = 1; $errstr[] = "Phone number should be entered as digits in the following format: ###-###-####"; } if (empty($_POST['subject'])) { $error = 1; $errstr[] = "Please enter a subject"; } if(empty($_POST['message']) || preg_match("/^enter your message here$/i", $_POST['message'])) { $error = 1; $errstr[] = "Please enter a message"; } if(empty($_POST['imagetext'])) { $error = 1; $errstr[] = "Please validate the image code"; } else { include "securimage.php"; $img = new Securimage(); $valid = $img->check($_POST['imagetext']); if(!$valid) { $error = 1; $errstr[] = "The code you entered was incorrect"; } } if ($error == 1) { echo "<center>\n<font style=\"color: #FF0000\">\n"; foreach($errstr as $err) { echo "<li> " . $err .

lajollaig Posted October 15, 2007 Author Share Posted October 15, 2007 Ok, I read about that.. but what would be the code to put in? <? php obStart(); ?> Quote Link to comment Share on other sites More sharing options...
darkfreaks Posted October 15, 2007 Share Posted October 15, 2007 but it before session start(); it should solve your problem Quote Link to comment Share on other sites More sharing options...

lajollaig Posted October 15, 2007 Author Share Posted October 15, 2007 Thorpe: Thats the sticky i read, but didnt understand where to put the code.. thanks... So, ok, Darkfreaks, I need to change this: function Securimage() { if ( session_id() == '' ) { // no session has been started yet, which is needed for validation session_start(); } } to THIS?: function Securimage() { if ( session_id() == '' ) { // no session has been started yet, which is needed for validation ob_start(); session_start(); } } Quote Link to comment Share on other sites More sharing options...
darkfreaks Posted October 15, 2007 Share Posted October 15, 2007 yes that will output all buffering before the session starts Quote Link to comment Share on other sites More sharing options...
trq Posted October 15, 2007 Share Posted October 15, 2007 Sorry, I didn't realise you'd read the sticky, just wanted to give you some reasoning as to why you get this error. Just put ob_start at the top of your script. yes that will output all buffering before the session starts Sorry, but that makes little sense. ob_start puts all your content into a buffer which is then sent in one go at the end of processing. This enables you to modify headers wherever you like because they are all sent together with the rest of the content. Quote Link to comment Share on other sites More sharing options...
lajollaig Posted October 15, 2007 Author Share Posted October 15, 2007 Thank you Thorpe... So this is what I am having trouble understanding... I just need to put this: ob_start(); right after the <php? in the begining of the script.. to read as follows?: <?php ob_start(); /** * Project: Securimage: A PHP class for creating and managing form CAPTCHA images<br /> * File: securimage.php<br /> * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public * License as published by the Free Software Foundation; either * version 2.1 of the License, or (at your option) any later version.<br /> * * This library is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

lajollaig Posted October 15, 2007 Author Share Posted October 15, 2007 LOL.. I am honestly sorry, I dont know what the calling script would be... I have: 1) index.php - the regular page with the include code in it to bring in the form.php script. 2) form.php which brings in the secureimage.php script (has the session_start(): in it) 3) secureimage.php Which one would it be? AND Thank you for your help thus far.... Much appreciated as I am very nw to PHP Quote Link to comment Share on other sites More sharing options...
