feel stupid, but, how code checkbox in form?

Question

I do not understand why the examples in the manual not work. Here in the forum I do not see the ricgt code as well. I feel stupid.

I have a field, defined as checkboxes, values populated by other field. (I do not know how many values my client fills in there)

Please, how do I code this in my form? In the form, when coding {MYFIELDNAME} it just puts out all the values, no checkboxes there. This code does not work either:

{options:MYFIELDNAME}
<label class="checkbox">
<input type="checkbox" id="{MYFIELDNAME}" name="{MYFIELDNAME}[]" value="{option_value}"{checked}> {option_value}
</label>
{/options:MYFIELDNAME} 

Answer 1

Second time lucky!

I believe that Hansl was actually trying to have a check box field populate CartThrob item options.

That can be achieved by replacing his code with...

<select name="item_options[maat]">
  {maat}
    <option value="{item}">{item}</option>
  {/maat}
</select>

Don't feel stupid! You were very close.

The only thing you need to change is the ID and name attributes don't need the {}'s around them.

It should work if you make it...

{options:MYFIELDNAME}
    <label class="checkbox">
        <input type="checkbox" id="MYFIELDNAME" name="MYFIELDNAME[]" value="{option_value}"{checked}> {option_value}
    </label>
{/options:MYFIELDNAME}
