WordPress 站点集成 Google 自定义搜索引擎

建站超值云服务器,限时71元/月

小站的搜索功能出现了点问题,索性直接更改为Google自定义搜索引擎。可在折腾搜索功能的时候经历了一些坎坷,所以整理了下内容分享给大家。

1.登入https://accounts.google.com/ServiceLogin?continue=http://www.google.com/cse/all&service=cprose&hl=zh-CN&gl=us&passive=true,若没有Google的帐号可去简单注册一个。登入后,我们开始创建一个“定制Google搜索引擎“,如下图:

在输入框内输入要搜索的网站,这里需要注意的是索引整个网站还是只是文章部分。若是整个网站直接按照图中的提示填写即可,若是单纯搜索全部文章页面就可能会麻烦些。

若只想让Google搜索网站的文章页面,首先要确定WordPress固定链接的设置。

默认:http://www.domain.com/?p=123 在输入框中填入http://www.domain.com/?p=*

日期和名称型:http://www.domain.com/2013/03/19/sample-post/ 在输入框中填入http://www.domain.com/年份/月份/天/*

月份和名称型以此类推

数字型:http://www.domain.com/archives/123 在输入框中填入http://www.domain.com/archives/*

文章型:http://www.mywpku.com/sample-post/ 在输入框中填入http://www.mywpku.com/*/

伪静态HTML型:http://www.mywpku.com/sample-post.html 在输入框中填入http://www.mywpku.com/*.html

其余可以此类推。

可别忘了选择网站语言哦!完成后下一步吧。

2.接下来可以根据需要来更改Google搜索页面的背景颜色,按钮颜色等等。不过最重要的一点是将布局更改为全宽:

3.接下来我们对主题的搜索页面进行修改。在WordPress中输入一个搜索词,它将会显示出搜索页面,并按照搜索词来显示内容。不过现在我们需要变一下:显示出搜索页面后按照输入的内容来调用Google搜索引擎帮你搜索。

在主题目录中找到类似于search.php这样的文件,以我的主题来做个示例:

我将它删除至只剩下一个大概的结构:

<?php get_header(); ?>
<div id="content" class="group">
 
</div>
<?php get_footer(); ?>

<?php get_header(); ?> <div id=”content” class=”group”> </div> <?php get_footer(); ?>

去刚刚的自定义搜索引擎页面那获取代码吧,这是最后一步了。

很显然普通的代码已经不能满足我们的需求了,下方点击获取V1代码。

将获得的代码与search.php合并:

保存代码吧。

4.我们的工作还没有完成,接下来可能会出现输入搜索词无效的问题。因为是从外部调用谷歌搜索引擎,它自然不知道你要搜索什么,所以要从URL中提取出搜索词:

在刚刚修改完成的search.php文件中搜索

customSearchControl.draw('cse', options);

在它的下面添加如下代码:

1
2
3
4
5
var match = location.search.match(/q=([^&]*)(&|$)/);
if(match && match[1]){
	var search = decodeURIComponent(match[1]);
	customSearchControl.execute(search)
