Question

Using Orchard CMS 1.4.2, I’m having trouble posting a form in my custom module.

Here’s my view:

@model ProfileEntity

<h2>My Profile</h2>

@using (Html.BeginForm("Update", "Home", FormMethod.Post))
{
    @Html.AntiForgeryToken()

    @Html.LabelFor(m => m.FirstName)
    @Html.EditorFor(m => m.FirstName)

    @Html.LabelFor(m => m.MiddleNames)
    @Html.EditorFor(m => m.MiddleNames)

    @Html.LabelFor(m => m.Surname)
    @Html.EditorFor(m => m.Surname)

    <input type="submit" value="Save Profile"/> 
}

In my Module.txt file, I have the line:

AntiForgery: enabled

When I try posting this form, I get an exception:

[HttpAntiForgeryException (0x80004005): A required anti-forgery token was not supplied or was invalid.]

I have also tried using:

@Html.AntiForgeryTokenOrchard() 

instead of

@Html.AntiForgeryToken()

(I’m not sure of the difference)

but it gives the same error.

Look at one of dozens of example throughout the code of existing modules.

@using (Html.BeginFormAntiForgeryPost())
