@thejackshelton I found the solution in the application.

The Complex Forms Docs says that you get an object and not an array as a result of the form submission.

In your case, having a form name of just "worlds" would just return an object that has "worlds" as a property and ONE value since it's a key-value pair. The solution is to make the form like this

<label for="w1">A</label>
      <input id="w1" name="worlds.A" type="checkbox" value="A" />
      <label for="w2">B</label>
      <input id="w2" name="worlds.B" type="checkbox" value="B" />
      <label for="w3">C</label>
      <input id="w3" name="worlds.C" type="checkbox" value="C" />
      <button type="submit">Submit</button>

This will submit only a worlds object but its value will be the ones that you checked. The ones that you checked will of course, contain the actual value.

Now if you really want an array then you can do

export const useSubmitForm = routeAction$((data) => {
  console.log(inspect(Object.values(data.worlds), { depth: null })); // consoles the array
  zod$({ worlds: z.array(z.string()) });
});

This makes an array of the values of data.worlds and that's the array of all checked boxes for you.

Did I solve your problem?

p.s inspect is just a built-in function in node just to help me read the values.

@yousefmarey12
However, back-end frameworks usually provide data list acquisition or automatic type conversion. Normal form submission also has multiple checkbox data, so I think it is not intuitive.

Hey @rendaoer!

If you don't find the API intuitive, you could make a feature request in this repo with some context, the preferred API and the reasoning behind it.

PR's are always welcome too 💪

I'm going to close this issue, as it is not a bug in core or qwik city, and @yousefmarey12 has taken the time to find a solution for ya that works (and is documented)
