Error checking & JS

ok, i'm not sure if this should have went in the cs-s forum, but it involves php, so i put it here.

i'm getting an "Unterminated String Constant" error on line 4 of my error script.
heres the whole script:

PHP Code:


<?php

function error($msg)

{

?>

<html>

<head>

<script language="JavaScript1.1">

<!--

alert("<?php echo $msg; ?>");

history.back();

// End -->

</script>

</head>

<body>

</body>

</html>

<?

exit;

}

?>

and here's the html code. the error is coming up on line 4:

Code:

<html>
<head>
<script language="JavaScript1.1">
<!--
alert("One or more required fields was left blank.
Please fill them in and try again.");
history.back();
// End -->
</script>
</head>
<body>
</body>
</html>

I've checked the JS against another example i got in the forums search which involved disallowing right clicking. looked fine. anyone know why that error is coming up?

Code:

alert("One or more required fields was left blank. 
Please fill them in and try again.");

Without knowing much js, my guess is that the error is caused because you have broken the the string over two lines. Perhaps js doesn't like line breaks within statements; ie a statement must be on the one line. This is just a guess.

Try

Code:

alert("One or more required fields was left blank. Please fill them in and try again.");

But then, I don't know if JavaScript interprets the newlin charactger \n either.

funny you mention that:

PHP Code:


error("One or more required fields was left blank.\nPlease fill them in and try again.");

thats what error is sending

even

PHP Code:


error("One or more required fields was left blank.");

doesn't work

Is this a javascript error or a php error being generated?

/me feels dumb.
when i tried it w/o the \n, i hadn't uploaded the script again.
the \n caused the error. works fine with it as 1 line.
