Hello everybdoy!
I'm new in php and I need urgently help.

I am doing online shopping for my website.
The user can enter the shopping basket (cart.php) from different pages.

In cart.php I put three html buttons of which one is to continue the purchases.
So, is necesary to return to the page from which the user came to cart.php, I mean from different product type php pages
I tried this:

product1.php
============
<?php
...
$SESSION['frompage']=$SERVER['REQUEST_URI'];
...
?>

cart.php
========
<?php
...
$frompagecome = $_SESSION['frompage'];
...
?>
<script type="text/javascript">
function returnPrev(){
alert(' de donde viene ... : ' + <?php echo $frompagecome; ?>);
}
</script>
...
<button type="button" onClick="<?php echo returnPrev(); ?>">Continue purchase</td>
...

But, don't work when I click button to Continue purchase, in function returnPrev() don't work alert().
Where I'm wrong??? Can somebody help me, please?
Thank you!!

What does the output of your cart.php look like when you visit the page? (In other words, can you show us the Javascript code that is generated?)

 alert(' de donde viene ... : ' + <?php echo $frompagecome; ?>);

I do see a problem here in that the second JavaScript string won't have quotes around it.

Thank Weedpacket!! I found the error by your suggestion, the problem was quots before and after "<?php......".

<button type="button" onClick="javascript:cont******('<?php echo $frompagecome ?>')">Continuar a Comprare</button>

bradgrafelman: the code is exactly equal, but with this quotes in <button>.

Sorry by my question. I was distracted. Thank you again.
