PHP check a email.txt file or MySQL if exists before sending a message

**TheMadMidget** · Nov 21 '06, 05:39 PM

[PHP]
$str = strtoupper(file _get_contents(" emaillist.txt") );
if (strpos($str, strtoupper($Inp utedEmail)))
{//Already in file
}
else
{//New to file
}
[/PHP]
$InputedEmail will have to be declared yourself
strtoupper() lets makes all the characters uppercase to prevent captialization differences.

I just looked at that URL in your post and depending on how much of that you used, you may be able to take out the strtoupper() s and might need one strtolower(). It's up to you, but the code above will work regardless, though it might have redundancies.

So... is this correct? I don't have php to test it... please help.

Code:

<?php

$str = strtoupper(file_get_contents("emaillist.txt"));
if (strpos($str, strtoupper($email)))
    {

  	if ($_SERVER['REQUEST_METHOD'] == "POST") {

    		$realname = strip_tags($realname);
    		$email = strip_tags($email);
    		$feedback = "You already subscribed."

    		$subject = "Send Mail Feedback";
    		$message = "$realname, $email\n\n$feedback";

    	mail($email, $subject, $message);

    }
}

else
    {
	//New to file
  	if ($_SERVER['REQUEST_METHOD'] == "POST") {

    		$realname = strip_tags($realname);
    		$email = strip_tags($email);
    		$feedback = "You haven't subscribed yet.  We will add you into our mailing list."

    		$subject = "Sorry";
    		$message = "$realname, $email\n\n$feedback";

    	mail($email, $subject, $message);

    } 


?>

<html>
<head>
  <title></title>
</head>
<body>


<?php 
if ($_SERVER['REQUEST_METHOD'] == "POST") {
    
    $realname = $_POST['realname']; 
    $email = $_POST['email']; 
    $feedback = $_POST['feedback']; 
    
    echo("<p><b>The following message was sent to $email\n");
    echo("$feedback");

    }
    else {
?>


  <form action="<?php echo $_SERVER['PHP_SELF']; ?>" METHOD="POST">
    Name: <input type="text" name="realname" size="25"></td></tr>
    Email: <input type="text" name="email" size="25"></td></tr>
    Feedback: <textarea name="feedback" rows="4" cols="40" wrap="physical"></textarea>
  <input type="submit" value="Send Feedback">
  </table>
  </form>


<?php } ?>

</body>
</html>

Hey, I tested the script, however it doesn't work correctly.

It went to the else statement. Any idea why?

the emaillist.txt file contains

myemail1@yahoo. com,
myemail2@yahoo. com,
myemail3@abc.co m

I'm not sure if it matter with breakline, or a comma added after each one

Thanks
