Passing value throught php, javascript and html

Take in mind the following; the code below and programs associated at it is runs perfectly.

<script>
   window.vorderby = "YEAR"
   exibelivrosAJAX();
</script>

but, when I did the modify below gave me the following error: Uncaught ReferenceError: YEAR is not defined

<script>
   window.vorderby = <?php echo $_POST['formorderby']; ?>;
   exibelivrosAJAX();
</script>

Looking for and reading tons of messages I did the following:

<script type="text/javascript" src="funcoesJS.js">
   window.vorderby = <?php echo $_POST['formorderby']; ?>;
   exibelivrosAJAX();
</script>

and the error was solved. But, the function exibelivrosAJAX() don't run.

Below you can see the two pieces of code that I think can help you to understand a little better.

1st piece of code in the primary file: echo " ";

2nd piece of code in another php file: window.vorderby = ; exibelivrosAJAX();

Could you help me to understand it? Thanks a lot! Marcos.

You still need the JS quotes:

<script>
   window.vorderby = "<?php echo $_POST['formorderby']; ?>";
   exibelivrosAJAX();
</script>

In the 2nd example, your code is not executed [and therefore you get no error] because of the src attribute of the script tag.

window.vorderby = "<?php echo $_POST['formorderby']; ?>";
