popup help

[rrayner]

I have this bit of code which should do an alert popup which did work until i tried to put a line feed into it what am I doing wrong

 

if ($linecount > 24)

{

 

echo "<script type=\"text/javascript\">alert('Hello\n How are you?')</script>";

 

}

?>

 

Thanks

You're echoing the line-feed in PHP, not JS. That means:

 

alert('Hello

How are you?')

 

... Is the JS being sent to the browser, which is invalid syntax. Strings can't span over multiple lines without a backslash at the end of the previous line. In PHP you can send the literal string "\n" by escaping it with a backslash (so a double backslash really):

 

echo "<script type=\"text/javascript\">alert('Hello\\n How are you?')</script>";

 

Or by using single quotes, because special characters aren't parsed in single quote strings:

 

echo '<script type="text/javascript">alert("Hello\n How are you?")</script>';

 

Although there's no need at all to use PHP to echo the string, you could just close the PHP tag and re-open it after:

 

{
    ?>
    <script type="text/javascript">alert('Hello\n How are you?')</script>
    <?php
}
