Newbie how to style php

I have some php code that I would like to style and ideally stay on the same page and not go to another page. But I know nothing about php, it is for a captcha. I would like the code for a div and some way of naming the div so that I can style it, I want the div to remain on the same page when I tried to give the div an id, I developed an php error. Which frightened me, so I removed it.

PHP Code:

---

if (!$resp->is_valid) {
    // What happens when CAPTCHA entered incorrectly ...$redirect = "../thanks.html";  
    // What happens when CAPTCHA entered incorrectly ...
die ("<h3>Error</h3>The reCAPTCHA wasn't entered correctly. Go back and try it again." .
         "(reCAPTCHA said: " . $resp->error . ")");
   } else {
    // Successful captcha, so continue on with the email ...
  } 


---

You should be ok with;

Code:

---

if (!$resp->is_valid) {
    // What happens when CAPTCHA entered incorrectly ...$redirect = "../thanks.html"; 
    // What happens when CAPTCHA entered incorrectly ...
die ("<div id='message'><h3>Error</h3>The reCAPTCHA wasn't entered correctly. Go back and try it again.</div>" .
        "(reCAPTCHA said: " . $resp->error . ")");
  } else {
    // Successful captcha, so continue on with the email ...
  }

---

Notice I used id='message' rather than id="message" - the quotes probably broke it.
You can also use id=\"message\" as long as you put a backslash before each quote to escape them :)

and the CSS;

Code:

---

#message {
background:yellow;
color:black;
padding:10px;
border:1px solid black;
}

---

He/she could also initiate the calling with single quotes rather than double quotes as the variable is being concocted anyway.

Could you be more clear about the "go to another page"? Is the address of the page changing or are you not getting all of the code you except to see? In what you've posted for code there is no reason for it to be loading another page so we'd need more code to troubleshoot that.

Yes, the page is going to another url.
I thought that if I put it in an error div it would stay just below the original recaptcha. Thanks for the tip on single quotes, I will try that.

I tried to do it again but alas, it threw up an error again.
The error is on the closing div line so it is in the wrong place.

PHP Code:

---

if (!$resp->is_valid) {
    // What happens when CAPTCHA entered incorrectly ...$redirect = "../thanks.html";  
    // What happens when CAPTCHA entered incorrectly ...
die ("<div id='captcha'><h3>Error</h3>The reCAPTCHA wasn't entered correctly. Go back and try it again." .
         "(reCAPTCHA said: " . $resp->error . </div>")");
   } else {
    // Successful captcha, so continue on with the email ...
  } 


---

Quotes in the wrong place, you can't have html in php. Please include your error message in future postings it will help identifying the problem.

PHP Code:

---

if (!$resp->is_valid) {
    // What happens when CAPTCHA entered incorrectly ...$redirect = "../thanks.html";  
    // What happens when CAPTCHA entered incorrectly ...
die ("<div id='captcha'><h3>Error</h3>The reCAPTCHA wasn't entered correctly. Go back and try it again." .
         "(reCAPTCHA said: " . $resp->error . "</div>)");
   } else {
    // Successful captcha, so continue on with the email ...
  } 


---

If you dont want it to redirect we will need to see the code, or you can try adding // in front of a line with header("location: $redirect"); that is a guess though, could break something...

There is a lot of code to add, but I will do so here: This is the process.php which processes the form.

PHP Code:

---

<?php  
session_start();

require_once('recaptchalib.php');
  $privatekey = "Removed";
  $resp = recaptcha_check_answer ($privatekey,
                                $_SERVER["REMOTE_ADDR"],
                                $_POST["recaptcha_challenge_field"],
                                $_POST["recaptcha_response_field"]);

// Get variables from your form ...  
$username = $_POST['name'];
$useremail = $_POST['email'];
// Who the form gets sent to ...  
$recipient = "removed";
$subject = "Website Form";  

// Where to go after the user submits the form ...  
$redirect = "../thankyou.html";  

if (!$resp->is_valid) {
    // What happens when CAPTCHA entered incorrectly ...$redirect = "../thanks.html";  
    // What happens when CAPTCHA entered incorrectly ...
die ("<div id='captcha_error'>The reCAPTCHA wasn't entered correctly. Go back and try it again." .
         "(reCAPTCHA said: " . $resp->error . ")</div>");
   } else {
    // Successful captcha, so continue on with the email ...
  }

$message = "
================================
Name:  $username
Email:  $useremail
-----------------------------------------
$fmessage
================================
";  

$extraheaders = "From: $useremail\n\nReply-To: $useremail\n\n";  

if (! mail($recipient, $subject, $message, $extraheaders))
  echo "Mail did not send for some reason.";  

header("Location: ".$redirect);  

?>

This is the form iteself.

PHP Code:

---

<form id="form" action="process.php" enctype="multipart/form-data" method="post" name="form_to_email">
<fieldset>
<legend>Enquiry Form</legend>
<p><label for="name"><span>Name</span></label><input id="name" name="name" size="35" type="text" /></p>

<script type="text/javascript">
        var RecaptchaOptions = {
            theme : 'clean',
            tabindex : 0
        };
</script><noscript><p>Please enable javascript in your browser to post this form</p></noscript>
<?php
require_once('recaptchalib.php');
$publickey = "Removed";
echo recaptcha_get_html($publickey);
?>
<p><input id="submit" class="submit" name="submit" type="submit" value="Submit" /></p></form>

What I am trying to find out how to do, is that if there is an error with the recaptcha, I want the error displayed underneath the recaptcha, at the moment it goes to a new url. Been searching the web for days now, I cant write php code or pay anyone to write code for me. But I thought if I put the code in a div it should stay underneath the recaptcha.

Are you getting an error message still or just redirected?

The redirect is

Quote:

---

header("Location: ".$redirect);

---

so make that

PHP Code:

---

//header("Location: ".$redirect); 


---

Its OK I dont think you understand, sometimes I want the page to redirect to the thanks page. But if the code is wrong I just want the errror message to remain underneath the recaptcha box.

Oh, okay try this.

PHP Code:

---

<?php  
session_start();

require_once('recaptchalib.php');
  $privatekey = "Removed";
  $resp = recaptcha_check_answer ($privatekey,

Thanks for your post, That produced the error but it did not show the recaptcha and the error should only show when there is an error in the recaptcha. Dont worry I will have to think of something else.
