Storing Drupal Form Checkboxes in a Database

Working on a form that will have 25 checkboxes in a checkboxes set. I need to store the checked keys in a database, and be able to restore the Edit form to it's checked state. I do have a solution, but it just seems odd. This is my first effort at a form and am looking for a best practice on how to solve this problem.

A prototype of my checkboxes set:

$form['medical'] = [
      '#type' => 'checkboxes',
      '#title' => $this->t('Medical Conditions you currently or have previously suffered.'),
      '#options' => [
        'Asthma' => $this->t('Asthma'),
        'Anxiety' => $this->t('Anxiety'),
        'Diabetes' => $this->t('Diabetes'),
        'Schizophrenia' => $this->t('Schizophrenia'),
        'Low Blood Sugar' => $this->t('Low Blood Sugar'),
        'High Blood Pressure' => $this->t('High Blood Pressure'),
        'Stroke' => $this->t('Stroke'),
        'HIV' => $this->t('HIV'),
        'IBS' => $this->t('IBS'),
      ],
      '#default_value' => $savedArray,

I get the checked keys using

$medical = $form_state->getValue('medical');
$chked = implode(',', $medical);

This gives me a comma separated string, something like something like 'Asthma,Diabetes,Low Blood Sugar,Stroke,IBS,0,0,0,0'.

I get the portion before the first ',0', the first unchecked checkbox and save that to the database.

$chked = substr($chked, 0, strpos($val, ',0'));

So the database is storing a comma separated list of Key values that represent the checked boxes.

To restore the state of the form, I get that string value from the database and explode it into an array, and use that array as the #default_value of the checkbox set.

 $savedArray = explode(',', $chked)
 #default_value => $savedArray

This all works, but it just seems pretty weird. I am new to Drupal and php. Is this an reasonable solution? Is there some built in functionality that manages this? This feels a lot like Jr programmer hackery to me!

Checkbox disabling an input

I want to make it so when the user clicks the checkbox , the player Two input goes disabled. My problem is that the input remains disabled in both cases, doesn't matter if checkbox is checked or not.

const Initialization = (function() {
  p1 = '';
  p2 = '';

  const playerOne = document.querySelector('#player1')
  const playerTwo = document.querySelector('#player2')
  const checkAI = document.querySelector('#computer')
  const startButton = document.querySelector('#start')

  startButton.addEventListener('click', () => {
    p1 = Player(playerOne.value)
    p2 = Player(playerTwo.value)
  })

  if (checkAI.checked = true) {
    playerTwo.disabled = true;
  } else {
    playerTwo.disabled = false;
  }

  return {
    p1,
    p2,

  }
})();

<label>Computer: <input type="checkbox" id="computer"></label><br/>
<input type="text" id="player1"><br/>
<input type="text" id="player2"><br/>
<input type="button" id="start" value="Start" />

Tick checkbox for timestamp in google sheet

I'm creating a request/problem form in google form and responses are viewable and editable in google sheet. In the google sheet, I would like to have a timestamp checkbox for myself to whenever I'm done with the problem.

It is look like this

...

Also, This is the function I put in column K(the timestamp) and the column J is the checkbox column.

=ArrayFormula(IF(ROW(K:K)=1,"DATE",IF(ISBLANK(K:K),"DATE",IF(J:J = true,IF(K:K<>"",K:K,NOW()),""))))

The column K function in sheet

The function for column K work as intended and I just need to manually add the checkbox in column J which is fine enough.

But, the problem is happen when a new form is submitted and update the google sheet. Error message appear " "array result was not expanded because it would overwrite data in K81."

The problem

My objective as I mention above is to have a timestamp checkbox for each problem submitted by google form. Is there are any way to work around this?

Create Checkbox on table with JavaScript

I'm building an app and on this app I have to add items on a table, and I would like to add a checkbox on each line that I add, but I'm having troubles on trying to do that. Would you know how to add a checkbox on each line that I add on the table?

below is the code where I add line per line to my table

function addDataToTbody(nl, data) { // nl -> NodeList, data -> array with objects
  data.forEach((d, i) => {
    var tr = nl.insertRow(i);
    Object.keys(d).forEach((k, j) => { // Keys from object represent th.innerHTML
      var cell = tr.insertCell(j);
      cell.innerHTML = d[k]; // Assign object values to cells   
    });
    nl.appendChild(tr);
  })
}

I tried to do something like

tr.append("<td> <div class='form-control'>\
    <input type='checkbox' /> \
    <label for='chk'/>select</div>\
</td>");

But that just adds a text to my table and not the checkbox itself.

<div id="table-wrapper" class="table-responsive">
      <table class="table table-hover" id="PartData">
           <thead>
               <tr>
                   <th scope="col">#</th>
                   <th scope="col">FUNÇÃO</th>
                   <th scope="col">DESCRIÇÃO</th>
                   <th scope="col">QUANTIDADE</th>
                   <th scope="col">FABRICANTE DO PAINEL</th>
                   <th scope="col">PEÇA</th>
                   <th scope="col">REVISÃO</th>
               </tr>
           </thead>
           <tbody>
               <tr>
               </tr>
           </tbody>
       </table>
   </div>

above is my HTML code.

Thanks in advance!
