Save WooCommerce Order details in custom table - php

Question

I have created a custom database in table order-master in which I will save WooCommerce order total amount, shipping charges and token.
For this, I have edited paypemts.php file, code is below:
<?php
include_once($_SERVER['DOCUMENT_ROOT'].'/canadiapharma.com/wp-config.php' );
global $woocommerce;
global $wpdb;
echo '<h3>Custom Calculation :</h3>';
$amount_2 = $woocommerce->cart->get_cart_total();
$ship_raw = floatval( preg_replace( '#[^\d.]#', '', $woocommerce->cart->get_cart_shipping_total() ) );
$ship = $ship_raw - 3600;
echo '<strong>Shipping :</strong>';
echo $ship;
$nano=WC()->cart->cart_contents_total;
echo '<br>';
$total_amt = $nano+$ship;
echo '<strong>Total :</strong>';
echo $total_amt;
echo '<br>';
$salt = 'dAta_EnC!=';
$token_raw = base64_encode($total_amt. $salt);
$token = preg_replace(sprintf('/=/', $salt), '', $token_raw);
echo '<strong>Token :</strong>';
echo $token;
$wpdb->query("INSERT INTO order_master (payment_amt, ship, token) VALUES ('$total_amt', '$ship', '$token')" );
?>
This code works fine and stores the data to the database. But it stores the data as soon as the checkout.php page loads. So, I made some changes and created an onclick event on Place Order button in checkout.php page.
OnCLick Event:
<?php echo apply_filters( 'woocommerce_order_button_html', '<button type="submit" class="button alt" name="woocommerce_checkout_place_order" id="place_order" value="' . esc_attr( $order_button_text ) . '" data-value="' . esc_attr( $order_button_text ) . '" onclick="dbinsert()">' . esc_html( $order_button_text ) . '</button>' );
?>
dbinsert():
<script>
function dbinsert() {
var myKeyVals = { amount : <?php echo $total_amt; ?>., ship : <?php echo $ship; ?>., token : <?php echo $token; ?> }
var saveData = $.ajax({
type: 'POST',
url: "savedata.php",
data: myKeyVals,
dataType: "text",
success: function(dbinsert) { alert("Save Complete") }
});
saveData.error(function() { alert("Something went wrong"); });
}
</script>
onclick event executes perfectly but doesn't know why data is not going into the database. Below is my savedata.php file.
<?php
global $wpdb;
$total_amt = $_POST['amount'];
$ship = $_POST['ship'];
$token = $_POST['token'];
$stmt = $wpdb->query("INSERT INTO order_master (payment_amt, ship, token) VALUES ('$total_amt', '$ship', '$token')" );
$stmt->bindparam('payment_amt', $total_amt);
$stmt->bindparam('ship', $ship);
$stmt->bindparam('token', $token);
if($stmt->execute())
{
$res="Data Inserted Successfully:";
echo json_encode($res);
}
else {
$error="Not Inserted,Some Probelm occur.";
echo json_encode($error);
}
?>
Please help me to fix this issue.

Try by changing your ajax url url: "savedata.php", to url: "<?php echo admin_url('admin-ajax.php?action=save_order_data');?>" and add below code in your theme's function.php
add_action('wp_ajax_nopriv_save_order_data', 'save_order_data');
add_action('wp_ajax_save_order_data', 'save_order_data');
function save_order_data() {
global $wpdb;
$total_amt = $_POST['amount'];
$ship = $_POST['ship'];
$token = $_POST['token'];
$stmt = $wpdb->query("INSERT INTO order_master (payment_amt, ship, token) VALUES ('$total_amt', '$ship', '$token')" );
$result = $wpdb->query($wpdb->prepare($stmt));
if($result)
{
$res="Data Inserted Successfully:";
echo json_encode($res);
}
else {
$error="Not Inserted,Some Probelm occur.";
echo json_encode($error);
}
}
Updated:
There is an error in var myKeyVals = { amount : <?php echo $total_amt; ?>., ship : <?php echo $ship; ?>., token : <?php echo $token; ?> }. Change your var myKeyVals as below:
var myKeyVals = { amount : "<?php echo $total_amt; ?>",
ship : "<?php echo $ship; ?>",
token : "<?php echo $token; ?>" }
You need to write php code in "" in javascript.
Hope this helps.
