Post value from checkbox to

Hi!

Im trying to figure out how to post either 0 or 1 depending on what value is selected in below switch.
I can generate a 0 or a 1 and show it on the page with id=“console-event” but i cant figure out how to parse the value in to input name=“oppethus” and post it.

<form method="post" name="form2" action="boka_edit.php" id="form2">
   
<div class="form-check pl-0 mt-2">
<input class="form-check-input" type="checkbox" id="oppethus" data-toggle="toggle" data-width="150" data-size="lg" data-off="Privat" data-on="Öppen" data-onstyle="success" data-offstyle="danger" >
<label class="form-check-label" for="oppethus">Välj öppen om alla är välkomna</label>

<script>

  $(function() {
$('#oppethus').change(function() {
  $('#console-event').html(+ $(this).prop('checked'))
})
  })

</script>
</div>


<p id="console-event">placeholder for 1 or 0</p>  
<input type="hidden" id="997" name="oppethus" value="0">

In JQuery you can do like so

<label><input id="cb" name="cb" type="checkbox">confirm</label>
<button id="btn">Confirm</button>

<script>
    $( document ).ready(function() {
      $("#btn").click(function() {
        $("#cb").prop( "checked", true );
      });
    });
</script

If you send the form type checkbox to PHP then PHP will only receive a value if the checkbox is checked . And you must add a name tag too. So you should try to use isset().

<?php
if(isset($_POST['cb'])) {
    // checkbox is checked
}

Thanks for the feedback, but maby i took the code to much out of context let me clarify.
So when submitting im sending date(bookingdate) timeslot(slotid) from session(fastighet) swtich checkbox öppen(oppethus). Method sugested did not work as intended for me. How can i post either 0 or 1 to oppethus?

The way a checkbox works is, it is either checked and passing a value, or it isn’t checked and won’t send anything. You are safe to assume that if it was not sent in the request, that it is false.

Is that signifying something? Like there is an opening if it is green?

If switched to green it meeans that the meet is not private all members can attend.
Im cool with it not sending anything if its not switched to green it can just send a 1 if set to green.

T.

That’s essentially what would happen. If it is checked, it would send whatever you have in the value attribute. If it is not checked, it won’t send any value to the processor.
