WordPress使用$wpdb->get_结果自定义分页

我可以通过$wpdb->get_results从Wordpress数据库中获取自定义数据，比如so$results=$wpdb->get_results$query，OBJECT；但是，我想使用paginate_链接对数据进行分页

它目前没有显示带有分页链接的数据，我想我的错误可能在$results=$wpdb->get_results$query.“ORDER BY id DESC LIMIT”范围内$偏移量'，'$每个页面的项目，对象

我的代码：

    global $wpdb;
    $table_name = $wpdb->prefix . 'templates';
    $items_per_page = 3;
    $offset = ( $page * $items_per_page ) - $items_per_page;

    $page = isset( $_GET['cpage'] ) ? abs( (int) $_GET['cpage'] ) : 1;

    $query = 'SELECT * FROM '.$table_name;

    $total_query = "SELECT COUNT(1) FROM (${query}) AS combined_table";

    $total = $wpdb->get_var( $total_query );


    $results = $wpdb->get_results( $query.'ORDER BY id DESC LIMIT'. $offset.', '. $items_per_page, OBJECT );

    $results = $wpdb->get_results( $query, OBJECT );

    if(!empty($results)) {
    echo"<table class=\"table table-hover\">";
        echo"<thead>";
            echo"<tr>";
                echo"<th>Id</th>";  
                echo"<th>Date</th>";
                echo"<th>Name</th>";
                echo"<th>Image src</th>";
                echo"<th>Category</th>";
                echo"<th>Preview Link</th>";
                echo"<th>BuiltWith</th>";
                echo"<th>Price</th>";

            echo"</tr>";
        echo"</thead>";
        echo"<tbody>";
        foreach($results as $row){  


            echo"<tr>";
                echo"<td>". $row->id . "</td>";
                echo"<td>". $row->tdateTime ."</td>";
                echo"<td>". $row->tName ."</td>";
                echo"<td>". $row->tName ."</td>";
                echo"<td>". $row->tCategory ."</td>";
                echo"<td>". $row->tPreview ."</td>";
                echo"<td>". $row->tBuiltWith . "</td>";
                echo"<td>". $row->tPrice ."</td>";
            echo"</tr>";
        }

        echo"</tbody>";
    echo"</table>";

    }


    echo paginate_links( array(

        'base' => add_query_arg( 'cpage', '%#%' ),

        'format' => '',

        'prev_text' => __('&laquo;'),

        'next_text' => __('&raquo;'),

        'total' => ceil($total / $items_per_page),

        'current' => $page

    ));

试试这个代码

<?php

    ob_start();
    $pagenum = isset( $_GET['pagenum'] ) ? absint( $_GET['pagenum'] ) : 1;

    global $wpdb;
    $table_name = $wpdb->prefix . "templates";


    $limit = 10;
    $offset = ( $pagenum - 1 ) * $limit;

    $total = $wpdb->get_var("SELECT COUNT(id) FROM $table_name ");              

    $num_of_pages = ceil( $total / $limit );

    ?>

    <?php   
        $questionnaire_data = $wpdb->get_results("SELECT * FROM $table_name desc LIMIT $offset, $limit", OBJECT );          
        $rowcount = $wpdb->num_rows;            

    ?>
        <h1>Result</h1>     

        <table class="wp-list-table widefat fixed striped" style="width: 99%;">
            <tr>
                <thead>
                    <th style="width: 5%;"><strong>S.No</strong></th>                       
                </thead>
            </tr>
            <tbody>
            <?php 
                if($rowcount ) {
                    $i=1;                           

                    foreach ($questionnaire_data as $key=>$singledata) {    
                        echo "<tr class='no-items'>";
                        echo "<td>".$i."</td>";                         
                        echo "</tr>";
                        $i++;
                    }
                } else {
                    echo "<td colspan='4' align='center'> No details(s) found </td>";
                }
            ?>
            </tbody>            
            <tfoot>
                <tr>
                    <th style="width: 5%;"><strong>S.No</strong></th>                       
                </tr>
            </tfoot>        
        </table>

    <?php
        $page_links = paginate_links( array(
            'base' => add_query_arg( 'pagenum', '%#%' ),
            'format' => '',
            'prev_text' => __( '&laquo;', 'text-domain' ),
            'next_text' => __( '&raquo;', 'text-domain' ),
            'total' => $num_of_pages,
            'current' => $pagenum
        ) );

        if ( $page_links ) {
            echo '<div class="tablenav" style="width: 99%;"><div class="tablenav-pages" style="margin: 1em 0">' . $page_links . '</div></div>';
        }
    }

更新

我已经测试了这个，它在我的网站上运行。有几件事：

将我的$query替换为您的

全局$wpdb每个关于全局变量的注释，因为它超出了范围

get_results在未告知其他信息时返回一个对象。第二个参数是返回类型

代码如下：

如果最后一页的行数少于3行或第一页的行数少于3行，则最后一页将出现错误502。
