I need help with collecting all the selected checkbox options from Special Orders and display it as text strings inside the modal. The checked options should be separated by commas.

I’m clearly new to JS, I have tried to look for solutions but I can’t seem comprehend them at all and have been stucked in this part for ages.

the code is here…

<form action="save_schedule.php" method="post" id="schedule-form">
  <input type="hidden" name="id" value="">
  <div class="form-group mb-2">
    <label for="title" class="control-label">Title</label>
    <input type="text" class="form-control" placeholder="Title" name="title" id="title" required>
  </div>
  <div class="form-group mb-2">
    <label for="recipient" class="control-label">Name of the Recipient</label>
    <input type="text" class="form-control" placeholder="recipient" name="recipient" id="recipient" required>
  </div>
  <div class="form-group mb-2">
    <label for="phone" class="control-label">Phone Number</label>
    <input type="text" class="form-control" placeholder="Username" placeholder="Phone number" name="phone" id="phone" required>
  </div>
  <div class="form-group mb-6">
    <label for="orders" class="control-label">Special Orders</label>
    <div class="form-group row">
      <div class="col-sm-6">

Checkbox: <input type="checkbox" id="myCheck" onclick="myFunction()">
<p id="text" style="display:none">Checkbox is CHECKED!</p>

JavaScript

function myFunction() {
  // Get the checkbox
  var checkBox = document.getElementById("myCheck");
  // Get the output text
  var text = document.getElementById("text");

  // If the checkbox is checked, display the output text
  if (checkBox.checked == true){
    text.style.display = "block";
  } else {
    text.style.display = "none";
  }
}

Almost everything the form submits can be found in global $_REQUEST variable.

First debug/check what your form-submit produces, like:
```
var_dump( $_REQUEST );
```
But (as mentioned in comments) your checkbox-inputs do not have any names, hence they never get submitted, to fix that set the name attribute in HTML like:
```
<input type="checkbox"
       name="myCoolCheckbox"
       id="my-checkbox-id"
       checked="checked">
<label for="my-checkbox-id">My Checkbox title</label>
```
However, you want to simply show a list of checked check-boxes, for that try something like:
```
var labels = '';

var _form = $('#schedule-form');
_form.find('[type="checkbox"]').each(function () {
    if (labels !== '') {
        labels += ', ';
    }
    labels += $(this).text();
});

// Fill placeholder:
var _details = $('#event-details-modal');
_details.find('#checked-options').text(labels);
```
Also, add to modal the placeholder’s HTML:
```
<dt class="text-muted">Checked options</dt>
<dd id="checked-options" class=""></dd>
```

Your checkbox inputs do not have a name.
<input/> needs a name.

If you use JavaScript to add the names, that is insane. Did you develop this code on your own, or did you copy and paste? If this copy and paste I could help you develop code that will work very well. There is no need to use JavaScript.

                                            <div class="form-check">
                                              <label class="form-check-label">
                                              <input type="checkbox" class="form-check-input">
                                              Pancit
                                              </label>
                                            </div>

See the name="Pancit"

                                            <div class="form-check">
                                              <label class="form-check-label">
                                              <input type="checkbox" name="Pancit" class="form-check-input">
                                              Pancit
                                              </label>
                                            </div>
