if statements keep running - STOP!!

[unistake]

I have made a script that allows a user to change their email address. It works BUT if the email address they have chosen is already registered the script does not cut off - it continues to the next if statement and changes the email address anyway.

 

I am trying to put a stop to it using exit() and exit; but it does not work.

 

Any tips?

 

<?php
//////////////////// checking new email is not already registered /////////////////
if ($_POST['newemail'] && $_POST['newemail1'] !="") {

if ($_POST['newemail'] == $_POST['newemail1']) {
	$sql2 = "SELECT email FROM Members WHERE email='$_POST[newemail]'";
	$result2 = mysqli_query($cxn,$sql)
		or die ("Couldn't execute query 2");

	$num2 = mysqli_num_rows($result2);

	if ($num2 > 0) { $updateerror = "The email address you have chosen is already registered.";
					 include("my-account.php")
					 exit();  // TRYING TO STOP THE SCRIPT HERE (IF $num2 > 0)
					 exit;
	}
	else { echo "You can have this new email address";}
}
else { echo "Your email addresses do not match. Please try again.";	}
}
else {}

// THIS SCRIPT CONTINUES TO CHANGE THE EMAIL ADDRESS DESPITE IT ALREADY BEING REGISTERED.
if ($_POST['newemail'] == "") { $newemail = $_POST['currentemail']; }
else { $newemail = $_POST['newemail']; }
$newemail1 = $_POST['newemail1'];
?>

exit will definitely stop your script in its tracks, are you sure its even getting to the exit call?

yes it is as the whole script below is updating information it should not!

 

I will have another look at it.

yes it works, error on my part.
