问题描述
我有一个 wordpress 简码，其中包含一些其他简码.执行第一个短代码时，我想使用正则表达式过滤掉其他短代码.
I have a wordpress shortcode which contains some other shortcodes inside it. When the first shortcode is executed i want to filter out other shortcodes using a regex.
[main_code]
[sub_code id='testid']test content[/sub_code]
[sub_code id='testid' name='testname']test content[/sub_code]
[/main_code]
当我执行 main_code 时，我想将 sub_code 过滤到一个数组中并访问其属性，而不将 sub_code 作为短代码执行.
When i execute the main_code i want to filter the sub_code into an array and access its attributes without executing sub_code as a shortcode.
任何有知识可以为我提供解决方案的人都非常感激.
Anyone who has knowledge to give me a solution is highly appriciated.
推荐答案
如果要内搭的话，我建议:
If you want to match the inner parts, then I'd advise:
preg_match_all('~\[sub_code([^\[\]]*)]([^\[\]]+)\[/sub_code]~', $content, $result);
[^\[\]] 匹配任何没有方括号的内容.因此可以确保其中不存在其他短代码.
The [^\[\]] matches any content without square brackets. So it's ensured no other shortcodes can exist within.
