这个函数在localhost上返回分页，但是当我在我的网站上传时，分页不在那里工作

Question

    function get_product_detail(){
    global $woocommerce, $wpdb, $current_user;
    $user =  $current_user->ID;

  

我用于数据显示的查询

$ sql =＆＃34; SELECT * FROM $wpdb->postmeta wpmeta INNER JOIN $wpdb->posts wp ON wpmeta。post_id = wp。ID WHERE wpmeta。{{1} } =＆＃39;＆＃34; $ current_user-＆GT; ID＆＃34;＆＃39;     和wpmeta。meta_value =＆＃39; _customer_user＆＃39;和wp。meta_key =＆＃39; shop_order＆＃39;和wp。post_type =＆＃39; wc-processing＆＃39; GROUP BY wp。post_status＆＃34 ;;     如果（isset（$ _ REQUEST [＆＃39;提交＆＃39;]））{                 $ applct_name = $ _REQUEST [＆＃39; applct_name＆＃39;];                 $ applct_email = $ _REQUEST [＆＃39; applct_email＆＃39;];                 $ applct_msg = $ _REQUEST [＆＃39; applct_msg＆＃39;];                 $ product_name = $ _REQUEST [＆＃39; product_name＆＃39;];                 $ product_number = $ _REQUEST [＆＃39; product_number＆＃39;];                  $ current_user = wp_get_current_user（）;                 $ usermeta = array（                         ＆＃39;名称＆＃39; = GT; $ applct_name，                         ＆＃39;电子邮件＆＃39; = GT; $ applct_email，                         ＆＃39; PRODUCT_NAME＆＃39; = GT; $ PRODUCT_NAME，                         ＆＃39;消息＆＃39; = GT; $ applct_msg                         ）;

ID

  

分页从这里开始

            $flag = 0;
            if($flag==0){
            add_user_meta($user, 'applicant_invite_by', $usermeta);


$headers = 'From: Backcheckgroup.com <noreply@backcheckgroup.com>' . "\r\n";
            wp_mail( $applct_email, 'Verfication Required', $applct_msg, $headers);
            $flag=1;
            echo 'Form submited';
            }else{

                echo 'Already submited';
                }
        }
    echo '<table class="order_detail">';
    echo '<tr>
        <th>No.</th>
        <th>Product ID</th>
        <th>Product Name</th>
        <th>invite user</th>
        <th>Status</th>
    </tr><tbody>';

  

这里印有分页

    $query = $wpdb->query($sql);
    $total = $query;
    $items_per_page = 3;
    $page = isset( $_GET['cpage'] ) ? abs( (int) $_GET['cpage'] ) : 1;
    $offset = ( $page * $items_per_page ) - $items_per_page;

    $service = $wpdb->get_results( $sql . " LIMIT ".$offset.", ".$items_per_page."" );


    foreach( $service as $results ) {

          $orderID = $results->post_id; 
            $order          = new WC_Order($orderID); 
            $status         = $order->status;

            $order_items    = $order->get_items(); 


            if(count($order_items))
            {
                $j=1;
                foreach($order_items as $item){

                    $item_name          = $item['name'];
                    $product_id         = $item['product_id'];
                    $qty                = $item['qty'];

                    echo '<tr class="collaps"><th><span>+</span></th><th>'.$product_id.'</th><th>'.$current_user->billing_first_name.' / '.$current_user->billing_company.'</th><th>Invited(0/'.$qty.')</th><th>Completed(0/'.$qty.')</th></tr>';
                    for($i=1; $i <=$qty; $i++){
                         $numbers = rand(0,100);
                        echo  '<tr class="sub-rows"><td>'.$j.'</td>';   
                        echo '<td>'.$product_id.'</td>';    
                        echo '<td>'.$item_name.'</td>'; 



    echo '<td><a href="javascript:void(0)" data-toggle="modal" data-target="#myModal_'.$numbers.'">invite</a></td>';


                            popup($numbers,  $qty, $item_name,  $user, $product_id);
                        $j++;
                            echo '<td>'.$status.'</td></tr>';   
                    }   


                } 

            } 
        } 
         echo '</tbody></table>';
