prob while 'header' in php

[believeinsharing]

I am trying to add captcha to my contact us form....

I did that but I do have prob while validating captcha.

 

As i know captcha validation should be on server side.

my code is:

 

---

<?php

session_start();

$captcha=$_SESSION['captcha_code'];

$ecaptcha=$_POST['code'];

echo "actual captcha :".$captcha ."</br>";

echo "entered captcha:".$ecaptcha;

$_SESSION['captchaError']==false;

if ($ecaptcha==$captcha)

{

 

echo "right captcha entered";

}

else

{

$_SESSION['captchaError']==true;

echo "wrong captcha entered";

        header('Location:contactus.php') ;

}

 

 

?>

---

 

because, I m using  header('Location:contactus.php') it showing contactus.php directly without error msg;

 

is their any other way to do this?

thanks in advance

Right, the page is not displayed until processing completed and you are redirecting the user to a different page before processing completes. But, since you are already storing the captcha error in session data you can simply use that on the contactus.php page to display the error.

@Psycho:

thx for reply, I am going that my contactus.php form has following code:

---

if ($_SESSION['captchaError']==true)

{

echo "<p id='contErrorMsg' style='display: none;color:red;'>Please fill the required fields</p>";

}

?>

---

and i m setting $_SESSION['captchaError'] value in send.php file

when contactus page will reload it will check $_SESSION['captchaError'] value n base on tht will display or not above <p>

 

my que is is their any way to check that page is loading first time or second time.

 

Thanks in advance

Sure, you could store a session value each time that page is loaded. But, I'm not really understanding what you are REALLY trying to achieve. I think the issue you are having is that when loading contactus.php you don't know if the error was a previous error or a new error. If that is the case, then check for the error as you do now - then remove the error.

if ($_SESSION['captchaError']==true)
{
    echo "<p id='contErrorMsg' style='display: none;color:red;'>Please fill the required fields</p>";
    $_SESSION['captchaError'] = false;
}
