preg_replace 未在 WordPress 插件中替换
跟进我之前的问题，我想用以下格式的链接替换全大写*单词的每个实例：
dictionary.com/browse/<TERM>
我正在使用的 preg_replace 调用是这样的：
$content = preg_replace('#[A-Z][A-Z]+#', '<a href="//dictionary.com/browse/$1">$1</a>', $content);
使用 http://gskinner.com/RegExr，看起来我的正则表达式是正确的，并且它应该< /em> 在每次查找时进行替换。
我是否在 preg_replace 调用中或在将插件/过滤器注册到 Wordpress API 时做错了什么？
调用的完整上下文：
function define_filter($content){
$content = preg_replace('#[A-Z][A-Z]+#', '<a href="//dictionary.com/browse/$1">$1</a>', $content);
}
add_filter('the_content', 'define_filter');
* 我使用 [AZ][AZ]+ 语法来确保我不匹配“I”和“A”等单词
In follow-up to my previous question, I want to replace every instance of an ALL-CAPS* word with a link of the following format:
dictionary.com/browse/<TERM>
The preg_replace call I am using is this:
$content = preg_replace('#[A-Z][A-Z]+#', '<a href="//dictionary.com/browse/$1">$1</a>', $content);
Using http://gskinner.com/RegExr, it appears I have my regex correct, and that it should be replacing on each find.
Have I done something wrong, either in the preg_replace call, or pehaps in the registration of the plugin/filter to the Wordpress API?
Full context of the call:
function define_filter($content){
$content = preg_replace('#[A-Z][A-Z]+#', '<a href="//dictionary.com/browse/$1">$1</a>', $content);
}
add_filter('the_content', 'define_filter');
* I'm using the [A-Z][A-Z]+ syntax to ensure I do not match words like "I" and "A"

我相信该函数需要返回替换的结果：
此外，该正则表达式看起来不正确。如果您想匹配全部大写的整个单词，那么
您还需要
$0（整个匹配），而不是$1（第一个捕获组，您的正则表达式不支持没有）I believe the function needs to return the result of the replacement:
Also, that regex doesn't look right. If you want to match a whole word in all caps, it's
Also, you want
$0(the whole match), not$1(the first capture group, which your regex doesn't have)
