Using Ajax to store checkbox in database - php

Question

Update: The code is working. I had an incorrectly named table in my php file.
I have the following that I've found from some snippets during my searches for help however I cannot get it to work. What I am trying to accomplish is clicking a check box and it automatically populate a row in my database that I can refer to on any other page. Right now when I click the checkbox, nothing happens.
HTML
<td><input type="checkbox" name="<?php echo $brow['WorkOrder']; ?>" value="<?php echo $brow['WorkOrder']; ?>"></td>
Ajax
<!-- Checkbox storage -->
<script>
$(document).ready(function(){
$("input[type='checkbox']").on('click', function(){
var checked = $(this).attr('checked');
if(checked){
var value = $(this).val();
$.post('functions/checkBox.php', { value:value }, function(data){
// data = 0 - means that there was an error
// data = 1 - means that everything is ok
if(data == 1){
// Do something or do nothing :-)
alert('Data was saved in db!');
}
});
}
});
});
</script>
functions/checkBox.php
<?php
if ($_POST && isset($_POST['value'])) {
// db connection
include("../../db.php");
// sanitize the value
$value = mysql_real_escape_string($_POST['value']);
// start the query
$sql = "INSERT INTO TemporaryCheckBoxID (WorkOrder) VALUES ('$value')";
// check if the query was executed
if(mysql_query($sql)){
// everything is Ok, the data was inserted
print(1);
} else {
// error happened
print(0);
}
}
?>

To check whether checkbox is checked or not use as below and try
<script>
$(document).ready(function(){
$("input[type='checkbox']").on('click', function(){
var checked = $(this).is(":checked");
if(checked){
var value = $(this).val();
$.post('functions/checkBox.php', { value:value }, function(data){
// data = 0 - means that there was an error
// data = 1 - means that everything is ok
if(data == 1){
// Do something or do nothing :-)
alert('Data was saved in db!');
}
});
}
});
});
