PHP form - remove \r\n

[Gainax]

I have a form, which takes the input and when submitted it sends an email to me with the content.

 

One field is a textarea and when I get the email I get \r\n where someone has gone onto a newline in the text area.

 

My form is:

 

           <form  id="requestform" name="requestform" method="post" action="">

                                <p><label for="name">Name:*</label><br />
                                <?php echo (($nameOK) ? "" : "<p style=\"color:red;\"><strong>Invalid Name: </strong> Your name must be at least 3 letters<br /></p>"); ?>
                                <input name="name" class="text" type="text" id="name" value="<?=$_POST['name'] ?>" /></p>

                                <p><label for="address">Address:*</label><br />
                                <?php echo (($addressOK) ? "" : "<p style=\"color:red;\"><strong>Invalid Address: </strong> Please enter your full address<br /></p>"); ?>
                                <textarea name="address" class="text" name="address" cols="30" rows="5" value="<?=$_POST['address'] ?>" ></textarea><br /></p>
             <button  type="submit" name="send" value="send" style="height: 26px; width: 96px; border: 0px;" ><img src="images/send_request.jpg" alt="send" title=""  /></button>

 

And the code which takes the form data is:

<?php
if( isset($_POST['send']))
{

$nameOK = validateName($_POST['name']);
$addressOK = validateAddress($_POST['address']);


if ($nameOK && $addressOK )
{

                        $to = "example@example.com";
                        $subject = "Request";
                        $body = "Name: " . $name . "\n\n" . "Address: " .$address;

                        $headers = 'From: example@example.co.uk' . "\r\n" .
                        'X-Mailer: PHP/' . phpversion();
                        if (mail($to, $subject, $body, $headers))
                        {
                        header('Location: thankyou.php');
                        }
                        else
                        {

 

I've tried using nl2br around the $address variable, but I still get the \r\n after each linebreak

 

Am I doing anything wrong?

 

Thanks

You can also use trim().

I tried that too, and it didn't work

Can we see the code for the validate address function.

[Gainax]

      function validateAddress($address){
                //if it's NOT valid
                if(strlen($address) < 4)
                        return false;
                //if it's valid
                else
                        return true;
        }

LOL ok, well that was simple. Let's see your code that is using the functions nl2br() and or trim() so I can look it over for errors.

Warning going to lunch soon!

I had the following code:

 

$body = "Name: " . $name . "\n\n" . "Address: " .trim($address);

 

and then tried:

 

$body = "Name: " . $name . "\n\n" . "Address: " .nl2br($address);

well according to everything you provided which was not much, then your php setup must not support these popular functions. Because trim be default will strip both of the characters you are trying to remove. Or you can post more of your code for error checking. Also you may want to do some htmlspecialchars() to make sure html is not being injected.
