In radion button save value like 0 or 1,but in checkbox i save string like this

{"Friday":{"12-6":"12PM - 6PM","6-9":"6PM - 9PM"},"Saturday":{"12-6":"12PM - 6PM","6-9":"6PM - 9PM"}}

so how to get selected radio button and checkbox

Answer 1

I assume when you edit the form you have an array that contains the data you want to edit. Let's call that array $data.
You can check if the checkbox with the name availableday[Friday][9-12] should be checked like this:

if (isset($data['Friday']['9-12']) && $data['Friday']['9-12'] == '9AM - 12AM') {
    $checked = ' "checked"="checked"';
} else {
    $checked = "";
}

Then make the input look like this:

<li><input class="allday" type="checkbox" name="availableday[Friday][9-12]" value="9AM - 12AM"<?php echo $checked;?>></li>

You should do the same for all the other checkboxes.

for radio do the same but check if ($data['gender'] == 1) or 0
