Hi,
Can't understand how to do this:
User applied some filters on a category page and get some list of products. He enters a product page to view details and then goes to other filtered products with help of great next/previous navigation buttons that cs-cart have. But there is no ability for the user to return to the category page and not to lose all the filters applied.
I can get a current url in categories controller with the code Registry::get('config.current_url') but how to pass this value to the product controller. Or probably is there a way to pass a smarty variable from one template to another that have different controllers. I have tried to assign the variable in smarty with a scope=“global” attribute, it doesn't help.
Try make as in shippments:
{assign var="return_current_url" value=$config.current_url|escape:url}
{btn type="list" text=__("delete") class="cm-confirm" href="shipments.delete?shipment_ids[]=`$shipment.shipment_id`&redirect_url=`$return_current_url`"}
Thank you Cart-Power!
As I understand it right the specified button deletes a shipment and refreshes the page with the assigned redirect_url value, that is equal to the current page url. But in my example I need to remember the current url and pass it to another page and than use it there as a button or link (user is in categories controller and goes to the products controller). I can return him back with [font=Consolas,]cm-back-link [/font]microformat but it works with the first product page only. If user visits several pages via prev/next navigation it will not work the way I need. Or am I missing something?
Probably your method is to add the current url to the new url, so instead of usual
index.php?dispatch=products.view&product_id=1
user will have
index.php?dispatch=products.view&product_id=1&return_url=index.php&category_id=3
And then get the return_url value and assign it to the “back” button link. I will try it, though I thought there is a way to make it less noticeable for the user.
I make it work finally via php $_SESSION.
In categories.post.php via my_changes addon I have added
$_SESSION['category_return_url'] = Registry::get('config.current_url');
In products.post.php
if (!empty($_SESSION['category_return_url'])) {
Registry::get('view')->assign('category_return_url', $_SESSION['category_return_url']);
}
Now in my product template {$category_return_url} gives the desired url.
You can also try use $_SERVER['HTTP_REFERER'] value. It is always equal value of url of page is visited before.
