Populate multiple checkboxes with the same name (not using []-names) #41

Closed powerbuoy closed 1 month ago

powerbuoy commented 1 month ago

I have a form with multiple checkboxes, all named test (unfortunately, out of my control, not named test[]).

<input type="checkbox" name="test" value="foo">
<input type="checkbox" name="test" value="bar">

When trying to populate them using data like this {"test": ["foo", "bar"]} nothing happens.

Also, when fetching the form data as JSON I also only get the first checkbox.

Is there any way I can get around this problem?

(NOTE: Changing the name to test[] resolves the issue, but again, is impossible for me to do in this case).

Well I shouldn't have said impossible, because after some more tinkering I indeed managed to stick [] in the name attribute. But could still be useful to know whether or not this is doable without changing the name?

Hi. This is not possible with this library. The array syntax is required to make it an array.
