Hi experts, I have a contact form and when the form is submitted, if they form is not completed and I am writing the value back to the users so users do not have to re-type the whole thing..

I am using session to do that.

The problem is that every where ' character is replaces with  \'

How do I fix that...?

Thanks all.
if (isset($_SESSION['contactMsg']))
{
  $si = &$_SESSION['contactMsg'];
  $fname = isset($si['fname']) ? $si['fname'] : '';
  $lname = isset($si['lname']) ? $si['lname'] : '';
  $email = isset($si['email']) ? $si['email'] : '';
  $sujet = isset($si['sujet']) ? $si['sujet'] : '';
  $message = isset($si['message']) ? $si['message'] : '';
  unset($_SESSION['contactMsg']);
}
 
 
<form action="send_email.php" method="post" onSubmit="return validate_contact(this)">
	<table width="100%" border="0" cellspacing="0" cellpadding="0">
 
	  <tr>
		<td colspan="3"  class="TD-labels-header">Envoyer le message</td>
	  </tr>
	  <tr>
		<td class="TD-labels">Pr&eacute;nom:  <em class="required"> * </em> </td>
		<td class="TD-border">&nbsp;</td>
		<td class="TD-values"><input name="fname" id="fname" type="text" size="40" value="<?php echo htmlentities($fname, ENT_QUOTES, 'UTF-8');?>" /></td>
	  </tr>
	  <tr>
		<td class="TD-labels">Nom:   <em class="required"> * </em></td>
		<td class="TD-border">&nbsp;</td>
		<td class="TD-values"><input name="lname" id="lname" type="text" size="40" value="<?php echo htmlentities($lname, ENT_QUOTES, 'UTF-8');?>" /></td>
	  </tr>
	  
	  <tr>
		<td class="TD-labels">Courriel:  <em class="required"> * </em></td>
		<td class="TD-border">&nbsp;</td>
		<td class="TD-values"><input name="email" id="email" type="text"  value="<?php echo htmlentities($email, ENT_QUOTES, 'UTF-8');?>" /></td>
	  </tr>
	  <tr>
		<td class="TD-labels">Objet:  <em class="required"> * </em> </td>
		<td class="TD-border">&nbsp;</td>
		<td class="TD-values"><textarea name="sujet" id="sujet"><?php echo htmlentities($sujet, ENT_QUOTES, 'UTF-8');?></textarea></td>
	  </tr>
	  <tr>
		<td class="TD-labels">Message:  <em class="required"> * </em> </td>
		<td class="TD-border">&nbsp;</td>
		<td class="TD-values"><textarea name="message" cols="50" rows="10" id="message"><?php echo htmlentities($message, ENT_QUOTES, 'UTF-8');?></textarea></td>
	  </tr>
	  <tr>
		<td class="TD-labels">&nbsp;</td>
		<td class="TD-border">&nbsp;</td>
		<td class="TD-values"><?php echo recaptcha_get_html($publickey, $error); ?></td>
	  </tr>
	  <tr>
		<td class="TD-labels">&nbsp;</td>
		<td class="TD-border">&nbsp;</td>
		<td class="TD-values">
			<input name="form_secret" id="form_secret" type="hidden" value="<?php echo $_SESSION['FORM_SECRET'];?>"  />
			<input name="ip" id="ip" type="hidden" value="<?php echo $_SERVER['REMOTE_ADDR']; ?>" />
		</td>
	  </tr>		
	  <tr>
		<td colspan="3" class="TD-labels-header" style="padding-left:600px;"><input name="submit" id="submit" type="submit" value="Envoyer" class="blue_bttn" /></td>
	  </tr>								  								
  </table>
</form>	
 
 
And in the code:
 
if (!isset($_SESSION['contactMsg']))
{
  $_SESSION['contactMsg'] = array();
}
 
$si = &$_SESSION['contactMsg'];
// This part is for the email
$fname = clean($_POST['fname'], true);
$lname = clean($_POST['lname'], true);
$ip = trim($_POST['ip']);
$email = clean($_POST['email'], true);
$sujet = clean($_POST['sujet'], true);
$message = clean($_POST['message'], true);
$message = str_replace(array("\\r\\n", "\\r", "\\n"), "<br />", $message);
 
// This part if the form has problem. 
$si['fname'] = trim($_POST['fname']);
$si['lname'] = trim($_POST['lname']);
$si['email'] = trim($_POST['email']);
$si['sujet'] = trim($_POST['sujet']);
$si['message'] = trim($_POST['message']);
$si['ip'] = trim($_POST['ip']);

I think this has to do with your extensive usage of the htmlentities PHP function.
See here for reference: http://www.php.net/htmlentities

Try replacing the argument ENT_QUOTES            by ENT_NOQUOTES  .

Could you please post the clean function you're using? It's probably that one adding the \'s.

Oscar - I am not even using the clean function though.. this is weird...

But here is the clean function


function clean($str, $encode_ent = false) {
	$str  = @trim($str);
	if($encode_ent) {
		$str = htmlentities($str);
	}
	if(version_compare(phpversion(),'4.3.0') >= 0) {
		if(get_magic_quotes_gpc()) {
			$str = stripslashes($str);
		}
		if(@mysql_ping()) {
			$str = mysql_real_escape_string($str);
		}
		else {
			$str = addslashes($str);
		}
	}
	else {
		if(!get_magic_quotes_gpc()) {
			$str = addslashes($str);
		}
	}
	
	return $str;
}

Hey!

From what I see, you're using the clean function from line 74 to 79.

As you can see on your newly attached code sample, it adds slashes whether the IF case turns true or false. (but also strips)

Yours sincerely,
Oscar

line 74 - 79 - are for storing in the database. But line 83 - 87 - not using - this is my session variable.. right?

Hey.

Try removing the clean(); functions and see if everything goes well. Debugging an application / script is an important thing, and you shall always debug it, by removing / adding bits of your code. You can even try rewriting it a few times, just to improve it.

Yours sincerely,
Oscar.

Oscar, Thanks for your suggestions...

I think It has nothing to do with the clean() - since I ran with removing the function completely. and I am still getting the same '\

And about the META, I have:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
