Question

I have a condition in php based on some session variables. If condition passes, I want to call a Javascript function which is updating my current webpage. Is it possible to place such a call to Javascript function independent of a button or a link or the window load function?

Answer 1

If I am understanding you correctly, just use php to output the javascript function. It will fire once, if you need.

<?php
if ($_SESSION['condition']=="foo") {
    echo "<script>","/n";
    echo "doThisNow();","\n";
    echo "</script>","\n";
}
?>

Or, you could echo out the session variables as javascript variables in the same way, and then do the conditional check in javascript.
