how to write javascript code inside php

Issue

i have a got a form, on clicking the submit button:

1. I want to do some task in the same file (db task) AND
2. I want the form data to be sent to test.php with the redirection

here is my code

    <?php
    if(isset($_POST['btn'])){
        //do some task
    ?>
    <script type="text/javascript">
        var e = document.getElementById('testForm'); e.action='test.php'; e.submit();</script>
    <?php
    }
    ?>
<form name="testForm" id="testForm"  method="POST"  >
    <input type="submit" name="btn" value="submit" autofocus  onclick="return true;"/>
 </form>

but not able to submit the form, if i call the javascript code on onClick, it works.what is the problem in this code, Is there any work around for this

Solution

Just echo the javascript out inside the if function

 <form name="testForm" id="testForm"  method="POST"  >
     <input type="submit" name="btn" value="submit" autofocus  onclick="return true;"/>
 </form>
 <?php
    if(isset($_POST['btn'])){
        echo "
            <script type=\"text/javascript\">
            var e = document.getElementById('testForm'); e.action='test.php'; e.submit();
            </script>
        ";
     }
  ?>
