以上代码截取掉HTML标签,图片啊、[caption 啊等。
目前我用的是
<?php echo mb_strimwidth(strip_tags(get_the_content()), 0, 120,"...");?>
问题:貌似HTML标签没有被过滤掉

我觉得这样的替换比较完美,而且兼容其它标签
$content = '1月19日,装扮成《白蛇传》中“白娘子”(中)的演员在南京玄奘寺“腊八节品腊八粥”活动上为市民盛粥。 [caption id="attachment_45" align="aligncenter" width="432"]<a href="http://cqtlmx.com/wp-content/uploads/2013/01/baili.jpg"><img class=" wp-image-45 lazy" src="/static/imghwm/default1.png" data-src="http://cqtlmx.com/wp-content/uploads/2013/01/baili.jpg" alt="“白娘子”布施腊八粥(组图)" style="max-width:90%" style="max-width:90%"></a> “白娘子”布施腊八粥(组图)[/caption] 当日是中国传统的腊八节,南京玄奘寺熬制了咸、甜两种口味的上万份腊八粥,众多市民前来品粥祈福。 新华社记者孙参摄'; preg_replace(array("/]+>/s", "/\[[^\]]+\]/s"), '', $content);
话说[caption]
只算是BBcode不算是HTML标签吧,所以你用strip_tags
是木有效果的,所以你可以考虑先把BBcode转换为HTML标签再用strip_tags
就应该正常了吧。
如果格式都是这么统一的话,可以考虑用下面的代码:
$s = array('[caption', ']<a array></a><a>'); str_replace($s, $r, get_the_content());</a>
效率什么的我是不太清楚了,就当为你提供另外一种思路吧~
$pat[0]='/(\[caption)([\s|\S]+)\/>/'; $pat[1]='/\[\/caption\]/'; $str='[caption id="attachment_45" align="aligncenter" width="432"]<a href="http://cqtlmx.com/wp-content/uploads/2013/01/baili.jpg"><img class=" wp-image-45 lazy" src="/static/imghwm/default1.png" data-src="http://cqtlmx.com/wp-content/uploads/2013/01/baili.jpg" alt="“白娘子”布施腊八粥(组图)" style="max-width:90%" style="max-width:90%"></a> “白娘子”布施腊八粥(组图)[/caption]'; echo preg_replace($pat,'',$str);
不知道lz的期望输出结果是什么.
如果是想删除整个shortcode [caption][/caption]
用wp内置的函数remove_shortcode或者remove_all_shortcodes
如果是想保留
"白娘子"布施腊八粥(组图)
也很简单.
$content = wp_strip_all_tags(str_replace(array('[',']'),array(''),$content));

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.

The steps to build an efficient shopping cart system using sessions include: 1) Understand the definition and function of the session. The session is a server-side storage mechanism used to maintain user status across requests; 2) Implement basic session management, such as adding products to the shopping cart; 3) Expand to advanced usage, supporting product quantity management and deletion; 4) Optimize performance and security, by persisting session data and using secure session identifiers.
