Continue shopping doesn't work after changing to cookies

Continue shopping doesn't work after changing to cookies

I have tried several fixes from other posts.

adding this:
<?php
// WA eCart Redirect
if ($whichwatchdesigns->redirStr != "") {
session_commit();
header("Location: ".$whichwatchdesigns->redirStr);
}
?>
Did I put the session commit in the right place?

adding this to the top of the cart page:
<?php if(!session_id()) session_start(); ?>
That didn't do anything, maybe there is something I am supposed to change with this one?

I have the site on an old domain cart.php

Any help would be appreciated

try adding the following at line 1 of the cart.php page:

php:
<?php

error_reporting
(E_ALL);
ini_set('display_errors','on');
?>



to make sure there is not a php error occurring.

also add the following just before the </body> tag to make sure the session is being set properly:
<pre><?php var_dump($_SESSION); ?></pre>

I added the code and this is what comes up when I click continue shopping:
Notice: Undefined variable: _SESSION in /...../cart.php on line 133
NULL

If I click clear cart I get this displayed:
Warning: Cannot modify header information - headers already sent by (output started at /...../cart.php:5) in /....../WA_eCart/whichwatchdesigns_PHP.php on line 292

I had everything running fine with sessions, then changed it to cookies in the ecart object. Is there something else I should have done?

Is there a specific reason you changed to using cookies?


In reality, setting the cart to be cookie based is not a great idea, there a re a number of limitations to using a cookie based cart. The biggest limitation to using a cookie based cart is that cookies have a maximum size. You will only be able to add so many items to the cart before the maximum cookie size is reached.

This maximum size is different for each brow3ser, so there is no real way to anticipate when that size is reached.

Officially, the limits of using cookies are:
* 4 KB per cookie maximum
* 300 total cookies, for a total of 1.2 Mbytes maximum
* 20 cookies accepted from a particular server or domain

Unless you absolutely must use cookies for your cart, I dont recommend it.

I just want the items placed in the cart to remain there if the shopper closes the browser. Many times people will place items in the cart and not buy them at that time but come back and purchase later, or if they accidentally close the browser the items are cleared from the cart. It would be nice if they didn't have to search for the items again. Is there some other way to achieve this? It is not absolutely necessary. I have everything set up as static with no database or user login.

in the WA_eCart/WA_eCart_Definition_PHP.php file add the following at line 1:
<?php if(!session_id()) session_start(); ?>


See this knowledge base article for information on the headers already sent error:148/

in the file you sent, all of the code is double spaced, in other words that is causing there to be a blank line every other line, having the code be double spaced like will pretty much ensure that there is a blank line after every closing php tag "?>" and the next opening php tag "<?php" which will cause the headers already sent error.
