In Presta 1.6 there was the possibility to use the JS ajaxCart Object to add ajax functions to alter your products before they are appended to the Cart. I am trying to rediscover such an ability in Presta 1.7 where apparently the ajaxCart Object is no longer defined.
Unfortunately I do not have code or anything to show, I simply would need to know whether there is a proper way now, a hook or anything, to modify your products before adding them to the Cart?
If there is no proper way, I would also be thankful for improper ways. Did the ajaxCart Object get a different scope? Was it replaced by another mechanism? Unfortunately I did not succeed a whole lot in reverse engineering the changed.

I'm trying to maintain the "search_filters / facets_search_wrapper" status of the checks after changing between categories, for exemple, when the user selects "size: L" and changes the category to t-shirts, keep the "size:L" check active.
I've been thinking of saving some part of the URL that identifies the selected search filters, but I don't manage to find any solution for this.
Any ideas?
Thanks for your time!
Don't use any URL parameters, think about using Local Storage where you can filter out results on DOMReady, or you can use cookies and alter results with PHP.
Facet module is completely different in PrestaShop 1.7, there i'd suggest to use cookie method, if you are working on 1.6 tho, i'd go for a JS solution.
I have a listing page for an e-commerce website with various items (item_list.php). This page is generated with a PHP loop and displays each item inside a <li> element. Every item is a link to the same page, called item_details.php .
When clicking on the link i want to run a script that changes a SESSION var to a certain $id (which will be excracted from the <li> itself with .innerHTML function) and then allowing the browser to move into the next page (item_details).
This is needed so i can display the proper information about each item.
I think this is possible with Ajax but I would prefer a solution that uses JS and PHP only.
(P.S.This is for a University project and im still a PHP newbie, i tried searching for an answer for a good while but couldn't find a solution)
No JS or other client-side code can set session values, so you need either an ajax call to php, or some workaround. This is not a complete answer, but something to get you thinking and hopefully going on the project again.
The obvious answer is just include it in the link and then get it in PHP from the $_GET -array, and filter it properly.
item title
If, however, there is some reason this is not a question with an obvious answer:
1.) Closest what you're after can be achieved with a callback and an ajax call. The idea is to have the actual link with a click function, returning false so the link doesn't fire at once, which also calls an ajax post request which finally will use document.location to redirect your browser.
I strongly advice against this, as this will prevent ctrl-clicks causing a flawed user experience.
Check out some code an examples here, which you could modify. You will also need an ajax.php file which will actually set the session value. https://developers.google.com/analytics/devguides/collection/analyticsjs/enhanced-ecommerce#product-click
2.) Now, a perhaps slightly better approach, if you truly need to do this client-side could be to use an click handler which instead of performing an ajax call or setting session directly, would be to use jQuery to set a cookie and then access this data on the item_list.php -page.
See more information and instructions here: https://www.electrictoolbox.com/jquery-cookies/
<script>
$('product_li a).click(function(){
$.cookie("li_click_data", $(this).parent().innerhtml());
return true;
});
</script>
......
<li class="product_li">your product title</li>
And in your target php file you check for the cookie. Remember, that this cookie can be set to anything, so never ever trust user data. Test and filter it in order to make sure your code is not compromised. I don't know what you want to do with this data.
$_COOKIE['li_click_data'];
3.) Finally, as the best approach, you should look at your current code, and see if there is something you can re-engineer. Here's a quick example.
You could do the following in php to save an array of the values in the session on each page load, and then get that value provided you have some kind of id or other usable identifier for your items:
// for list_items.php
foreach($item as $i) {
// Do what you normally do, but also set an array in the session.
// Presuming you have an id or some other means (here as item_id), to identify
// an item, then you can also access this array on the item_details -page.
$_SESSION['mystic_item_data_array'][$i['item_id]] = $i['thedata'];
}
// For item_details.php
$item_id = // whatever means you use to identify items, get that id.
$data_you_need = $_SESSION['mystic_item_data_array'][$item_id];
Finally.
All above ways are usable for small data like previous page, filters, keys and similar.
Basically, 1 and 2 (client-side) should only be used, if the data is actually generated client-side. If you have it in PHP already, then process it in php as well.
If your intention is to store actual html, then just regenerate that again on the other page and use one of the above ways to store the small data in case you need that.
I hope this gets you going and at least thinking of how to solve your project. Good luck!
Json view of my paypal after payment is made
I am desperately trying to access the description which is under the transactions array but can't seem to find a way!
It's totally different if I want to access payment_method for instance all I do is this:
(By the way, I assigned this array to $method)
$method->payer->payment_method , but the same thing doesn't work if I want to access description. All I get is an error.
I'm using laravel 5.5, in case that makes a difference.
I'm doing this because I need to find a way to reference my product in the final page after the paypal payment has been made.
Looks like transactions in an array so if you would like the description of the first one that would look like this.
$method->transactions[0]->description
I know that we can design the layout in *.xml then in the action just invoke loadLayout, and renderLayout to render the blocks/views.
But, I have a question is:
- How can I load the layout at runtime?
If we have an action which does not really design its layout and will be decided how to render at runtime.
You can please consider the answer from the question for more clear.
Writing a new answer because it seems that you actually DO still want to render, you just want to render a different route's layout XML updates. I believe the _forward() method from Mage_Core_Controller_Varien_Action will allow you to do what you are describing with the least amount of pain.
You should add your action controller directory ahead of the catalog directory, create a ProductController with a viewAction, and check customer is not logged in - in this check you would call $this->_forward('customer','account','login');.
This approach though is going to require more effort in order to be usable, as I imagine that you want the user to be sent to the product page upon login. Have you seen Vinai Kopp's Login Only Catalog module? It should do this for you.
loadLayout() and renderLayout() just execute block output method toHtml() (usually) and take the resulting strings and apply them to the response object via appendBody(). In an action controller you can just call $this->getResponse()->setBody('response string'). How you build the string is up to you.
You can also use Mage_Core_Block_Flush to immediately send output to the browser without using the response object.
A bit of context: I need to cache the homepage of my CakePHP site - apart from one small part, which displays events local to the user based on their IP address.
You can obviously use the <cake:nocache> tag to dictate a part of the page that shouldn't be cached; but you can't surround a controller-set variable with these tags to make it dynamic. Once a page is cached, that's it for the controller action, as far as I know.
What you can usefully surround with the nocache tags are elements and helpers. As such, I've created an element inside these tags, which calls a helper function to access the model and get the appropriate data. To get at the model from the helper I'm using:
$this->Modelname =& ClassRegistry::init("Modelname");
This seems to me, however, to be a kind of iffy way of doing things, both in terms of CakePHP and general MVC principles. So my question is, is this an appropriate way of getting what I want to do done, or should it ring warning bells? Is there a much better way of achieving my objectives that I'm just missing here?
Rather than using a Helper, try to put your code in an element and use requestAction inside of the element.
see this link
http://bakery.cakephp.org/articles/gwoo/2007/04/12/creating-reusable-elements-with-requestaction
This would be a much better approach than trying to use a model in your helper.
Other than breaking all the carefully-laid principles of MVC?
In addition to putting this item into an element, why not fetch it with a trivial bit of ajax?
Put the call in its own controller action, such that the destination URL -> /controller/action (quite convenient!)
Pass the IP back to that action for use in the find call
Set the ajax update callback to target within the element with the results of the call accordingly
No need to muck around calling Models directly from Views, and no need to bog things down with requestAction. :)
