[Resolved] How do I make a radio button REQUIRED?

  • If you read this <http://contactform7.com/checkboxes-radio-buttons-and-menus/&gt;, you’ll see that by their very nature, radio buttons are required.

    The problem is that the radio button are NOT required when I hit SEND without filling in a selection, it sends just fine with NO value. So no, that does not help at all if I do not want to add a default value.
    As it stands now I will simply add ” default:1 ” before the first radio selection just so that will be required to leave it or change it.

    Just going by what the docs say. Sounds like it’s time for the CF7 creator to jump on this.

    Just as the doc says, radio buttons are “required” by nature. Setting a default value is always a good practice. When you don’t want to set a default option, you can use checkbox* tag with exclusive option instead. It behaves like radio buttons, but still works as checkboxes.

    I just had a look at the latest HTML5 spec for this and it looks different than the older version:


    Constraint validation: If an element in the radio button group is required, and all of the input elements in the radio button group have a checkedness that is false, then the element is suffering from being missing.

    With respect Takayuki, checkboxes don’t look exclusive, so making them exclusive for some questions is confusing and unnecessary – that’s what radio buttons are for.

    Take the example of a gender question – radio buttons are the obvious choice, having checkboxes would be downright weird because of their non-exclusive appearance. If it’s an important and required question, making one radio button option pre-selected is a recipe for unreliable results.

    Thanks for an awesome plugin!
