Image Verification

[rangana]

I'll stick on Adam's rendition.

- Use || in replacement of or.
- Use && in replacement of and.
- Use != in replacement of <>.

One last thing, I might be at mistake, but try to change this part:

Code: Select all

if(md5($verification).'a4xn' != $_COOKIE['tntcon'])


...into:

Code: Select all

if((md5($verification).'a4xn') != $_COOKIE['tntcon'])


Hope it helps.

I'm still getting the "Please make sure your Verification Code is correct. " line. :S


hmmm.

[dflynn]

Oh, didn't see Rangana's post. I'll try that.

[dflynn]

Still no luck

I will send you a full script which should work.

I stripped out the SQL part in my example but the rest should be the same.

I'll get back to you shortly.

[dflynn]

ok thanks again.

Code: Select all

<?php
$todo = $_REQUEST['todo'];
$firstname = $_REQUEST['firstname'];
$lastname = $_REQUEST['lastname'];
$message = $_REQUEST['message'];
$testimonial = $_REQUEST['testimonial'];
$verification = $_REQUEST['verification'];

if(isset($todo) and $todo=="post") {

$status = "OK";
$msg="";

if(!isset($firstname) || strlen($firstname) <2){
$msg=$msg."Your first name should be at least 2 characters long. <br />";
$status= "NOTOK";}

if(!isset($lastname) || strlen($lastname) <2){
$msg=$msg."Your first name should be at least 2 characters long. <br />";
$status= "NOTOK";}           

if(!isset($message)){
$msg=$msg."Please leave a message. <br />";
$status= "NOTOK";}

if ($testimonial != "yes"){
$testim="no";
}else{
$testim="yes";}

if(md5($verification).'a4xn' != $_COOKIE['tntcon']){
$msg=$msg."Please make sure your Verification Code is correct. <br />";
$status= "NOTOK";}

if($status != "OK"){
echo "<font face='Verdana' size='2' color=red>$msg</font><br><input type='button' value='Retry' onClick='history.go(-1)'>";
}else{


$datein = date("Y-m-d");

$query=mysql_query("INSERT INTO table(firstname,lastname,datein,message,testim) values('$firstname','$lastname','$datein','$message','$testim')");
echo "<p>Thank you for taking the time to sign the Guestbook.</p>";
setcookie('tntcon','');
}
}

echo "<p>Debugging info:</p>";
echo "<p>Submitted verification: ".$verification."</p>";
echo "<p>Required verification: ".$_COOKIE['tntcon']."</p>";

?>

I've added debugging info at the bottom which hopefully will point out any further issues.

I hope this helps.

Let me know.

So, in the debugging, it's not returning the image code from the cookie. The cookie is being stored no problem, it's just doesn't seem to find it.
Any ideas?

The link if you wanna test it out.

[rse]

if you add print_r($_COOKIE); below the other debugging lines what does it show?

Cheers
