Can not reach [HttpPost] action method in a block controller from Html.BeginForm()

Questions
1

I built a “CombineYourPurchase” block from where I need to post some products to the cart after clicking on a button.
I tried to use Html.BeginForm() method in my MVC view

        using (Html.BeginForm("TestAction", "CombineYourPurchaseBlock"))
       {                           
            <div>
                <button type="submit">@Html.WebSiteString("js.product.addtocart")</button>
            </div>
            }
        }

in order to reach the post method in CombineYourPurchaseBlockController.cs, but I can not reach it. Instead I am being redirected to “/site.axd/CombineYourPurchaseBlock/TestAction”.

    [HttpPost]
    public ActionResult TestAction(BlockModel currentBlockModel, CombineYourPurchaseBlockViewModel vm)
            {
              
                return new RedirectResult("/GetTestResult/Index", true);
            }

Is there another way I can access that post method in my block controller?

Is your CombineYourPurchaseBlockController class inheriting from ControllerBase?

3

Yes
public class CombineYourPurchaseBlockController : ControllerBase

Can you try with this:

using (Html.BeginForm("TestAction", "CombineYourPurchaseBlock", FormMethod.Post))
5

I tried, but it still doesn’t work

6

Did you add it to FieldTemplateSetupDecorator.cs?

When you using the

using (Html.BeginForm("TestAction", "CombineYourPurchaseBlock", FormMethod.Post))

we will instruct the ASP.NET Mvc framework to find the CombineYourPurchaseBlock-controller and post to the TestAction. If you instead send in null as the controller name the post will go to the current url instead.

Adding post actions into block-controller need to go directly to the controller and then a redirect need to be executed for the visitor, the reason is that you otherwise need to have the same action in the page-controller and in all other block-controllers, otherwise you will get the same exception as in Exception from block when POST is used where the method of POST not is found.

I set up a minimal example to test this locally and when posting from the block to a POST action on the block controller I hit my redirect back to the start page, as expected.

Have you made any changes to the routing config?
Can you hit the POST action if you strip the parameters?
