</body>If my comment is correct, and the issue here is that you have the correct amounts, but have lost the "meta information" of whether to add or subtract to the total, then I think the simplest solution would be to do the following:
Firstly change the value of the checkbox so that it reflects the action to take - ie if it is{-code-1} then make the value negative. So yourinput would be:
<input type='checkbox' name='payroll_group' value=" . ($row['category_type'] === '{-code-1}' ? $row["amount"] * -1 : $row["amount"]) . "class='form-check-input'>
Where($row['category_type'] === '{-code-1}' ? $row["amount"] * -1 : $row["amount"]) will check if thecategory_type is{-code-1} then multiplyamount by-1 otherwise keep the currentamount value. Note the surrounding parenthesis are necessary.
Then in your current js, you should end up with[-1000,35000,6500] in your current example. You can then do a simple loop to go through the array and add to a total, or you could use something like
var totalAmount = favorite.reduce(
function (total, amount) {
return parseInt(total) + parseInt(amount)
},
0 // The initial value to start with
)
