I am editing a code which supposed to update database when value is change, however it doesn't work, hope someone could help me fix it.
I am using DISTINCT to get the data and need to update a few data at the same time. it can display the value, but it can't save in database.
for example, I will using DISTINCT to get a few data which with the same date and I will change values among those data at the same time by using that code.
index.php
<script>
window.onload = function() {
$(".cal_amount").change(function() {
var auto_array = {};
//Step 1- On change use The closest() method to get the all input elements value of selected element row.
form_data = $(this).closest('tr').find('input, select');
//Step 2- On change Use map to store input elements value with name as key in the array.
var myArray = $.map(form_data, function(element) {
auto_array[element.name] = element.value;
//return {name: element.name, value: element.value};
});
form_data = $(this).closest('tr').find('input,select').serialize();
$.ajax({
data: {
action: 'update_price',
form_data: form_data,
},
url: 'updates_ok.php',
type: 'post',
beforeSend: function() {
},
success: function(data) {
if(data == 1){
alert('update sucessful')}
}
});
});
};
</script>

window.onload = function() {
