wordpress截取首页摘要内容的方法
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>本文实例讲述了在wordpress截取首页摘要内容实现方法,分享给大家供大家参考。具体分析如下：</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
这里截取就是利用了自定义的add_filter函数.在functions.php里加入下面代码后直接在主题模板里使用the_excerpt();就可以实现摘要输出了,实例代码如下:<br>
</p>
<div style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div style="margin: 0px; padding: 0px; outline: none; float: right; line-height: 25.2px; font-size: 14px;">
<span style="line-height: 25.2px; cursor: pointer;"><u>复制代码</u></span>
</div>
代码如下:</div>
<div id="phpcode5" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
//首页摘要 <br>
function lms_excerpt_length( $length ) { <br>
return 150; //150是摘要输出的字数 <br>
} <br>
add_filter( 'excerpt_length', 'lms_excerpt_length' );</div>
<br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>就上面这么处理,返回的摘要内容以[...]结尾,而且不自动添加Read More链接,需要继续处理一下,还是functions.php里添加如下代码:</span><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><div style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div style="margin: 0px; padding: 0px; outline: none; float: right; line-height: 25.2px; font-size: 14px;">
<span style="line-height: 25.2px; cursor: pointer;"><u>复制代码</u></span>
</div>
代码如下:</div>
<div id="phpcode6" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
//添加read more链接 <br>
function lms_continue_reading_link() { <br>
return ' <a href="'. esc_url( get_permalink() ) . '">' . __( 'Read More →' ) . '</a>'; <br>
} <br>
function lms_auto_excerpt_more( $more ) { <br>
return ' …' . lms_continue_reading_link(); <br>
} <br>
add_filter( 'excerpt_more', 'lms_auto_excerpt_more' );</div>
<br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>这样就完美了,效果如我首页,还可以直接定义一个函数,支持中文字符截取,比如字符串超过20个就需要截取,代码如下:</span><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><div style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div style="margin: 0px; padding: 0px; outline: none; float: right; line-height: 25.2px; font-size: 14px;">
<span style="line-height: 25.2px; cursor: pointer;"><u>复制代码</u></span>
</div>
代码如下:</div>
<div id="phpcode7" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
if(mb_strlen($str, "gbk") >20) <br>
{ <br>
$str = mb_substr($str, 0, 20, "gbk"); <br>
}</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
