This library automatically sets 0 value to unchecked checkbox, and 1 for checked. Especially useful for multiple checkboxes with the same name when receiving the form with PHP.

Before

.html

<input name="tasks[]" type="checkbox" checked />
<input name="tasks[]" type="checkbox" />
<input name="tasks[]" type="checkbox" checked />

.php

var_dump($_POST['tasks']);

// Expectation:
// array(2) {
//   [0]=>
//   string(1) "1"
//   [1]=>
//   string(0) "0"
//   [2]=>
//   string(0) "1"
// }

// Reality:
// array(2) {
//   [0]=>
//   string(1) "1"
//   [1]=>
//   string(0) "1"
// }

After

.js

cheghost("input[type=checkbox]");

.php

var_dump($_POST['isVisible']);

// Reality:
// array(3) {
//   [0]=>
//   string(1) "1"
//   [1]=>
//   string(0) "0"
//   [2]=>
//   string(0) "1"
// }
