How to decide if I should use the Post method

Coreysan 1,651 Reputation points

I'm working on a web store, and I'm at the part about adding a product when the user clicks "Add to Cart". I can do either:

  1. Write a form in the view with method=post
  2. Leave the form out, and use <a type="button" asp-action="Details" asp-route-id="@Model.Id">

Does it matter which technique I use for this event? I use POST in other places for sure, but when I'm just passing an integer, and adding product to a session variable, do I need to use a form?

    Hi @Coreysan , From your question, Both of these two methods can pass data to backend. But if you only want to pass an integer, I prefer to using the second method. Many platforms like Microsoft Q&A, Stack overflow are using <a> tag to pass id to backend. User's image
