Question

PHP Script
The php script that is executed once the form is filled out:

   <?php    
    $connect = mysql_connect($h, $u, $p) or die ("Connect Submit at this time.");
        mysql_select_db($db);

        ## Escape bad input including '/', '"', etc
        ////////////////////////////////////////////////////////////////
        if(!empty($_POST['InterestedEmail']))
            $subscriberEmail=mysql_real_escape_string($_POST['InterestedEmail']);
        ////////////////////////////////////////////////////////////////
        if(!empty($_POST['InterestedBrowser']))
            $subscriberBrowser=mysql_real_escape_string($_POST['InterestedBrowser']);
        ////////////////////////////////////////////////////////////////

        ## check for nmll values, if all are set, INSERT
        if (isset($_POST['submit'])) {
        $query="INSERT INTO launching(lauEmail, lauBrowser) 
        values('$subscriberEmail', '$subscriberBrowser')";
        mysql_query($query)  or die(mysql_error());
            #HERE
        }

        ?>

How do I get PHP to run this JS code: window.alert('Submitted. Thank you.') once the script reaches #HERE

Answer 1

You could end the PHP and restart it and just put the JS in there, or if you want to embed it right there in the PHP where you have #here then how about echo/print it:

echo "<script type=\"text/javascript\">";
echo "window.alert('Submitted. Thank you.')";
echo "</script>";
