Play 2 - Template index.scala.html - How do i write an hidden field in Scala?

[Laurent Bois]

Hi

In my project Play 2 ( i'm a beginner on Scala), i have un page view with the following input fields written in Scala.

    @form(routes.Addresses.newAddress()) {

        

        @inputText(addressForm("street")) 

        @inputText(addressForm("postalCode"))

        @inputText(addressForm("city"))

        @inputText(addressForm("country"))

           

        <input type="submit" value="Update">

        

    }

I need to add an hidden field "id" in this Edit Form to have the address primary key.

I don't find how to write this hidden field...any idea?

the html code woould be <input type="hidden" value="33" name="id" />

Thanks for your help

Laurent

What’s wrong with writing the HTML?

[Laurent Bois]

Nothing wrong except how do i get the addressForm value in scala?

[Julien Richard-Foy]

Oh sorry I misunderstood your question.
You can retrieve the "id" field of your form by writing
“addressForm("id")”. And then you can get the value of this field
using its “value” member:
<input type="hidden" value="@addressForm("id").value" name="id" />

Another reason to write the HTML directly is that the helper methods create labels as well as inputs. If by some means you did use a helper method, your hidden value would spawn non-hidden labels.

That's all they are, helper methods. There is nothing wrong with writing the HTML code directly as Julien stated, and in this case it is the only way.

That didn't work so well. Try again...

Why not just write your own helper?

Attached is an example.
