Please help with setting a new global variable!!!!

[ecroskey]

I need to set a new global variable that would come in from a link in an email. Below you will notice I have a variable called "adcode" attached to some value. I need to know how to pass this through the entire transaction and not lose it after the first click from within the site. So far including this variable does not damage the link in anyway, but once you arrive at the site and click on any other link it disappears.

 

<a href="http://www.xxx.com/catalog/product_info.php?adcode=xxxxxx&cPath=21_24&products_id=80">

 

How do I capture that variable and pass it along with that customers activities until they check out?

 

I really apreciate all the help I get here, this one happens to be a big, big, big deal to my company, so thank you very much!

 

 

Best Regards,

I am not exactly sure why, but I can follow the link into the site now, and when I click on "Add TO Cart" that is where my variable is being dropped.

 

I included in application_top.php the following thinking it was a SSL (HTTPS) problem:

 

if (isset($HTTP_GET_VARS['adcode'])) {

$adcode = $HTTP_GET_VARS['adcode'];

} elseif ( (getenv('HTTPS') == 'on') && isset($HTTP_GET_VARS['adcode'])) {

$adcode = $HTTP_GET_VARS['adcode'];

}

 

Does this seem like I am on the right track? I really need help with this.

This would be an embedded link in an email. Once you arrive at the site, you are on the product page, then you click add to cart and you go to the shopping cart page, but now when you click on checkout, it is dropping the code!

 

Any ideas?

You have to find on each page, where each link is, and code the link to include the variable that contains the parameter you wish to pass.

where would that go? Could you give me an example of where the code would or should be? I guess I don't know why it is passing through the first to pages and not continuing.

The second argument to tep_href_link is the parameters string. If the second argument is missing, you just need to add it in:

tep_href_link(FILENAME_SOMEFILE, ($HTTP_POST_VARS['adcode'] ? 'adcode=' . $HTTP_POST_VARS['adcode'] : ''));

Similarly, if it's empty, just replace the '':

tep_href_link(FILENAME_SOMEFILE, ($HTTP_POST_VARS['adcode'] ? 'adcode=' . $HTTP_POST_VARS['adcode'] : ''), "SSL");

If it is not empty

tep_href_link(FILENAME_SOMEFILE, $string);

then it gets a little more complicated:

tep_href_link(FILENAME_SOMEFILE, ($HTTP_POST_VARS['adcode'] ? $string . '&adcode=' . $HTTP_POST_VARS['adcode'] : $string));

or something like that. Whatever the third or later arguments say, just keep them as is (if they aren't there, leave them out).

I guess I don't know why it is passing through the first to pages and not continuing.  

 

Because you passed it through the first URL, but not the subsequent URLs.

 

You have to explicitly pass the parameter through each URL, it doesn't automatically pick it up in each subsequent link.
