前言

最近一直在写Bty3.0的项目,所以博客要么太水要么拖更,小杰深感抱歉,但是小杰也没有闲着,非网传《某某某作者沉迷王者堕落生活》

看gitee贡献图就能看得出小杰还是很勤奋的/干杯

Emlog魔改核心完成评论搜索功能

话说不多看干货,今天带来的是Emlog魔改核心完成评论搜索功能,该功能是《会飞的鱼》在本博客提出的建议,所以忙里偷闲简单弄了一下,完成此次操作。

教程

0、备份/admin文件夹(谨慎总是好的)

1、找到路径文件/admin/include/model/comment_model.php

2、直接替换以下全部内容(怕有些小白搞不清楚,大佬请直接对比代码即可)

<?php/** * 评论管理 * @copyright (c) Emlog All Rights Reserved */class Comment_Model { private $db; function __construct() { $this->db = Database::getInstance(); } /** * 获取评论 * * @param int $spot 0:前台 1:后台 2: 手机 * @param int $blogId * @param string $hide * @param int $page * @return array */ function getComments($spot = 0, $blogId = null, $hide = null, $page = null, $keyword = '', $type = 'comment') { $andQuery = '1=1'; $andQuery .= $blogId ? " and a.gid=$blogId" : ''; $andQuery .= $hide ? " and a.hide='$hide'" : ''; $andQuery .= $keyword ? " and a.$type like '%$keyword%'" : ''; $condition = ''; if ($page && $spot == 1) { $perpage_num = Option::get('admin_perpage_num'); if ($page > PHP_INT_MAX) { $page = PHP_INT_MAX; } $startId = ($page - 1) * $perpage_num; $condition = "LIMIT $startId, ".$perpage_num; } if ($spot == 0 || $spot == 2) { $sql = "SELECT * FROM ".DB_PREFIX."comment as a where $andQuery ORDER BY a.comment_top,a.date ASC $condition"; } else { $andQuery .= ROLE != ROLE_ADMIN ?

3、找到路径文件/admin/comment.php

按照下图选中区域进行添加代码

Emlog魔改核心完成评论搜索功能
$keyword = isset($_GET['keyword']) ? addslashes($_GET['keyword']) : ''; $type = isset($_GET['type']) ? addslashes($_GET['type']) : '';$addUrl_3 = $keyword ? "keyword=$keyword&" : ''; $addUrl_4 = $type ? "type=$type&" : ''; $addUrl = $addUrl_1.$addUrl_2.$addUrl_3.$addUrl_4;$comment = $Comment_Model->getComments(1, $blogId, $hide, $page,$keyword,$type); $cmnum = $Comment_Model->getCommentNum($blogId, $hide,$keyword,$type);

解释一下这里为什么要添加这段代码,因为官方在评论列表这块没有做keyword查找,所以需要添加一下

4、添加搜索表单,文件路径/admin/views/comment.php添加如下表单即可(个别模版自己调整位置和样式)

<div class="col-sm-6"> <form action="comment.php" method="get" class="form-inline"> <div class="form-group"> <select id="type" name="type" class="form-control"> <option value="poster">用户名</option> <option value="mail">邮箱</option> <option value="url">网址</option> <option value="comment">内容</option> </select> </div> <div class="form-group"> <input type="text" id="input_s" name="keyword" class="form-control" placeholder="搜索评论"> </div> </form> </div>

到这里教程就结束了,成品可以看下图。
