can a redirect to a local page from within a function?

[spryce]

Newbie question.

 

I have a form that uses reCaptcha. If the Captcha is entered correctly it posts the data.

 

Can I redirect the page using php or do I need to use javascript?

 

I was going to throw in

header('Location: thankyou.php');

but from my limited understanding this cannot be used anywhere except the very top of the page.

 

  if (!$resp->is_valid) {
//    What happens when the CAPTCHA was entered incorrectly
    die ("The reCAPTCHA wasn't entered correctly. Go back and try it again." .
         "(reCAPTCHA said: " . $resp->error . ")");
  } else {
  echo "Recapture entered correctly!"; // Just for testing purposes
	postdata($firstname, $lastname, $company, $email, $phone, $comments); // sends data to my databse

// this is where I would expect to redirect to a new page

  }

 

Thanks phpfreaks

PS - i did read the sticky on header errors.

 

I have a stack of $POST calls ie

$subject = check_input($_POST['subject']);

before my function. I assume this means that data is sent to the browser which is why I cant use the header function.

But the reCaptcha stuff doesnt work unless this comes first.

If echo "Recapture entered correctly!"; isn't commented out, the redirect surely won't work after it. Other than that, it's impossible to tell without the rest of the preceding code. Also, whenever you use a header() redirect, you should immediately follow it with an exit(); to stop the further execution of code in the script.

[.josh]

$subject = check_input($_POST['subject']);

 

You can have a header() call after that... $_POST is a global array of data the user submitted to the script.  You can have a header() call anywhere in your script, as long as there is no output before it (and even then you can, though it's not recommended)
