Question

Through an input field the color “green” is submitted.

Now, it takes requesting it.

In PHP it would be $_POST['color'].

I have thought it through, and have gotten it to this code:

The Example:

The Request for the ColorName – with VB.NET 2012 MVC 4:

    Public Class ColorPrintOutSubmitClassController
        Inherits System.Web.Mvc.Controller

        ' This method will handle GET
        Function PrintOutPage() As ActionResult
            Return View("PrintOutPage")
        End Function

        ' This method will handle POST
        <HttpPost>
        Function ColorPrintOut() As ActionResult
            ' Do something
            Response.Write("You submitted the color: " & Request.QueryString("ColorName") & "<br />")
            Return View()
        End Function
    End Class

The HTML:

    <form action="" method="post">
    <input type="text" name="ColorName" />
    <input type="submit" name="ColorName_SubmitButton" value="Print It Out!" />
</form>

The Questions:

The problem in this attempt is that the color name does not get printed out, as wanted.

1. Could the problem be rather on Reponse.Write, or Request.QueryString?
2. How does get the part which is to handle the GET – "invoked"?

Invoked = to put into effect or operation

Answer 1

It is not a QueryString, it is the POST itself. In C# it would just be:

Request["ColorName"];

So maybe just (not sure, don’t know VB):

Request("ColorName") 

But a better way to do this would be to actually bind to a MVC Model
