Mandating Fields

Any field with a name ending with a * is mandatory with Irma. This means that it must be filled in by the user in order for the form to be accepted.

For example, to make sure the user fills in the email field on the quickstart form, change the field name email to email * :

Your email: <input type="text" name="email *">

Mandating fields requires some error processing on the template. This can be achieved with the errors variable, which will contain the names of all missing fields.

<!--SCRIPT-- £errors~[ Please fill-in the following fields: $errors ]^[ Hello $name! Today, $date, your email address $email, has been added to the mailing list. ] -->

The above example uses Irma expressions. An expression is typically [$/£]variable~[if]^[else]#[then] . Expressions are fully documented in this manual.
