Captcha image not displaying

JeanieTallis · March 30, 2009

I have a captcha on my website register form, and it doesn't display. This is my register form. (You don't need it all)

<?php
require_once('settings.php');

if ( array_key_exists ( '_submit_check', $_POST ) )
{
	if ( $_POST['full_name'] != '' && $_POST['email'] != '' && $_POST['username'] != '' && $_POST['password'] != '' && $_POST['password'] == $_POST['password_confirmed'] && $_POST['country'] != '' && $_POST['user_code'] != '' && valid_email ( $_POST['email'] ) == TRUE )
	{
		if ( ! checkUnique ( 'Username', $_POST['username'] ) )
		{
			$error = 'Username already taken. Please try again!';
		}
		elseif ( ! checkUnique ( 'Email', $_POST['email'] ) )
		{
			$error = 'The email you used is associated with another user. Please try again or use the "forgot password" feature!';
		}
elseif (strcmp(md5($_POST['user_code']),$_SESSION['ckey']))
{ 
		 die("Invalid code entered. Please enter the correct code as shown in the Image");
  		} 
		else {		
			$query = $db->query ( "INSERT INTO " . DBPREFIX . "users (`full_name` , `Email` , `Username` , `Password` , `Country` , `date_registered` , `Random_key`) VALUES (" . $db->qstr ( $_POST['username'] ) . ", " . $db->qstr ( md5 ( $_POST['password'] ) ).", '" . time () . "', " . $db->qstr ( $_POST['email'] ) . ", '" . random_string ( 'alnum', 32 ) . "')" );

			$getUser = "SELECT ID, Username, Email, Random_key FROM " . DBPREFIX . "users WHERE Username = " . $db->qstr ( $_POST['username'] ) . "";

			if ( $db->RecordCount ( $getUser ) == 1 )
			{			
				$row = $db->getRow ( $getUser );

				$subject = "Activation email from " . DOMAIN_NAME;

				$message = "Dear ".$row->Username.", this is your activation link to join MyVee. In order to confirm your membership please click on the following link: <a href=\"" . APPLICATION_URL .

				if ( send_email ( $subject, $row->Email, $message ) ) {
					$msg = 'Account registered. Please check your email for details on how to activate it.';
				}
				else {
					$error = 'I managed to register your membership but failed to send the validation email. Please contact the admin at ' . ADMIN_EMAIL;
				}
			}
			else {
				$error = 'User not found. Please contact the admin at ' . ADMIN_EMAIL;
			}
		}							
	}
	else {		
		$error = 'There was an error in your data. Please make sure you filled in all the required data, you provided a valid email address and that the password fields match one another.';

This is my captcha image code

<?php
session_start();
header ("Content-type: image/png");

$rno = rand(1000,99999);
$_SESSION['ckey'] = md5($rno);

$img_handle = imageCreateFromPNG("bg1.PNG");
$color = ImageColorAllocate ($img_handle, 0, 0, 0);
ImageString ($img_handle, 5, 20, 13, $rno, $color);
ImagePng ($img_handle);
ImageDestroy ($img_handle);

?>

This is my css (I doubt it's needed but might be)

Know what the problem is? everything else seems to be fine for now.

Thanks if you can help.

I do believe you need

session_start();

on top of your registration form for the captcha to show

<?php
session_start();
   require_once('settings.php');

   if ( array_key_exists ( '_submit_check', $_POST ) )
   {
.......
?>

corbin · March 30, 2009

All of the image functions are entirely lower case. (ImageString should be imagestring for example).

That shouldn't be causing the error though.

Have you tried making errors show and then go to the image and look at the errors?

ini_set('display_errors', '1');

error_reporting(E_ALL);

JeanieTallis · March 30, 2009

I have put

session_start();

in, and that never worked.

also, corbin, where do I put that PHP? I tried it in both register and the image code. Nothing seem to appear up about errors.

A little image thing shows up for a millisecond, I managed to print screen it.

Make this small PHP file:

<?php
  phpinfo();
?>

Upload that and call it - check to make sure you've got GD installed. If you don't, that's the cause of your problem.

If you do it's something else. You're calling the captcha image correctly in your form (via HTML's IMG) so I'd say (at a guess) the error would then be in your captcha file.

Yesideez · March 30, 2009

Have you tried accessing "pngimg.php" directly in your browser to see if it works?

If it doesn't it very well could give you an error message saying why - something you wouldn't see when calling it within IMG.

JeanieTallis · March 30, 2009

Intelligent Yesideez.

It shows an error

http://myvee.co.uk/pngimg.php

Thats all it tells me.

What is GD and how would I call it too.

Yesideez · March 30, 2009

GD is just a library of graphic functions.

Without it you can't use the image functions you're using in "pngimg.php"

What is the error message you get?

JeanieTallis · March 30, 2009

I solved the problem, where it says 'BG1' I never uploaded that file! thanks for the help though guys, i think some of them points you picked out may of been an error too.
