Below is complete code to get all table rate shipping data including shipping zones, shipping methods by zone and rates by zone -
header('Content-type: application/json');
$json_file=file_get_contents('php://input');
$jsonvalue= json_decode($json_file,true);
global $wpdb;
global $woocommerce;
$active_methods = array();
$shipping_methods = $woocommerce->shipping->load_shipping_methods();
//echo "<pre>";print_r($shipping_methods);
foreach ( $shipping_methods as $id => $shipping_method ) {
if ( isset( $shipping_method->enabled ) && 'yes' === $shipping_method->enabled ) {
$data_arr = array( 'title' => $shipping_method->title, 'tax_status' => $shipping_method->tax_status );
if($id=='table_rate'){
$raw_zones = $wpdb->get_results("SELECT zone_id, zone_name, zone_order FROM {$wpdb->prefix}woocommerce_shipping_zones order by zone_order ASC;");
//echo "<pre>";print_r($raw_zones);
$shipping = array();
$shippingarr = array();
foreach ($raw_zones as $raw_zone) {
$zones = new WC_Shipping_Zone($raw_zone->zone_id);
$zone_id = $zones->zone_id;
$zone_name = $zones->zone_name;
$zone_enabled = $zones->zone_enabled;
$zone_type = $zones->zone_type;
$zone_order = $zones->zone_order;
$shipping['zone_id'] = $zone_id;
$shipping['zone_name'] = $zone_name;
$shipping['zone_enabled'] = $zone_enabled;
$shipping['zone_type'] = $zone_type;
$shipping['zone_order'] = $zone_order;
$shipping_methods = $zones->shipping_methods;
foreach($shipping_methods as $shipping_method){
$methodid = $shipping_method["number"];
$raw_rates[$methodid]['rates'] = $wpdb->get_results("SELECT * FROM {$wpdb->prefix}woocommerce_shipping_table_rates WHERE shipping_method_id={$methodid};",ARRAY_A);
}
$shipping['shipping_methods'] = $raw_rates;
$raw_country = $wpdb->get_results("SELECT location_code FROM {$wpdb->prefix}woocommerce_shipping_zone_locations WHERE zone_id={$zone_id};",ARRAY_N);
$shipping['countries'] = $raw_country;
$shippingarr[] = $shipping;
}
$data_arr['shipping_zones'] = $shippingarr;
}
$active_methods[ $id ] = $data_arr;
}
}
if(!empty($shippingarr)){
$result['success']='true';
$result['error']="0";
$result['msg']='Shipping methos found.';
$result['data']=$active_methods;
}else{
$result['success']='true';
$result['error']="0";
$result['msg']='Shipping methos found.';
$result['data']= array();
}
echo json_encode($result); `
