database problem checkboxes? Profile:edit form, checkbox error

Question

Spending several hours to tackle this, completely exhausted and see no solution any more. Do hope for some help here. Code 1 no problem. Code 2 throws error Field niveau has three items. all throw error.

The form you submitted contained the following errors

Invalid Selection
Invalid Selection
Invalid Selection

In a form this code:

Code 1

<ul class="forms-inline-list">
                 {options:gender_{language_code}}
            <li>
        <input type="radio" id="gender_{language_code}" name="gender_{language_code}[]" value="{option_value}"{checked}>
        <label for="checkbox">{option_value}</label>
            </li>
                {/options:gender_{language_code}}
               </ul>    

code 2

<ul class="forms-inline-list">
                 {options:niveau_{language_code}}
            <li>
        <input type="radio" id="niveau_{language_code}" name="niveau_{language_code}[]" value="{option_value}"{checked}>
        <label for="checkbox">{option_value}</label>
            </li>
                {/options:niveau_{language_code}}
               </ul> 

I swear, the two fields are the same, except for the name.

What is going on here?

Thanks a lot for saving may days.

Answer 1

Related to feel stupid, but, how code checkbox in form?

Chris Barret from Mightybigrobot (makers of Cartthrob abd Profile:edit) helped me out. The brackets have to go in a checkbox or radio select field. Working code is

<ul class="forms-inline-list">
                 {options:gender}
            <li>
        <input type="radio" id="gender" name="gender" value="{option_value}"{checked}>
        <label for="checkbox">{option_value}</label>
            </li>
                {/options:gender}
               </ul>
