How to submit 0 if checkbox is unchecked and submit 1 if checkbox is checked in HTML

Question

How to submit value 1 if a checkbox in a checkbox array is checked, and submit 0 if it\'s unchecked? I tried this but no luck. I am trying to grab this array in a php array

Answer 1

A better solution that solved this for me.

Problem: Both the hidden and the checked were sending to my server.

Solution:

if len(key) == 1 {
  value = false
} else {
  value = true
}

This way, if len(key) is 1 I know that only the hidden field was being send. Any other scenario means that the box is checked. Simple and easy.
