PHP - How Do I Use Php To Email A Pdf Of The Current Page?

i wanting users to be able to update there email address and check to see if the new email already exists. if the email is the same as current email ignore the check.
i have no errors showing up but if I enter a email already in the db it still accepts the new email instead of bringing the back the error message.
Code: [Select]
// email enterd from form //
$email=$_POST['email'];


$queryuser=mysql_query("SELECT * FROM members WHERE inv='$ivn' ") or die (mysql_error());
 while($info = mysql_fetch_array( $queryuser )) {
  $check=$info['email'];
 // gets current email //
}


if($check!=$email){
// if check not equal to $email check the new email address already exists//
$queryuser=mysql_query("SELECT * FROM members WHERE email='$email' ");
//$result=mysql_query($sql);
$checkuser=mysql_num_rows($queryuser);
if($checkuser != 0)
{
$error= "0";
header('LOCATION:../pages/myprofile.php?id='.$error.'');


}
}

cheers

Hello - I've come to an issue with something I'm working on and have searched around with no luck.

When editing user accounts I want it to not be able to change the e-mail address into existing ones on other rows, but when submitting the form it takes into account that this particular rows email address is the same as the one which was sent via $_POST and throws up the error.

The desired behaviour I want is for it to ignore the ID of the row which was posted, but take into account every other row.

Here's the code as it stands at the moment:

$email = $_POST['email'];
        $checkemail = mysql_query("SELECT email FROM users WHERE email='$email'");

} if (mysql_num_rows($checkemail) > 0) {

return $this->error("The e-mail address you provided is already associated with an account.");
}

sendmail.php

Code: [Select]
<?php

         $email = $_POST['email'];
         $to = $_POST['recipent']; 
         $subject = "SUBJECT HERE."; 
         $message  = "YOUR MESSAGE HERE"; 
         $header  = "From: $email " . "\r\n"; 

         $send = mail($to, $subject, $message, $header); 

         echo "Your invitations have been sent!"; 

   ?>
and this is invite.php
Code: [Select]
