【问题描述】：
我已经查看了这篇文章 (Multiple excerpt lengths in wordpress)，但很明显，它已经多次从我们现在的位置删除了 WordPress 版本。对于不同的区域，我也需要多个长度，但要去掉标签。我不在帖子上使用“摘录”框，因此它需要连接内容本身。我非常喜欢该页面上包含“短”、“常规”和“长”的建议答案，但我似乎无法让它发挥作用。
我在我的主页上的短代码循环中使用它，它以不同于其余 4 个帖子的方式显示组中的第一个帖子。我只在第一篇文章末尾包含代码，因为其他文章不包含摘录。
这是我目前拥有的。也许有人可以看到我在哪里搞砸了：
函数.PHP 类摘录{
// Default length (by WordPress)
public static $length = 55;
// So you can call: my_excerpt('short');
public static $types = array(
'short' => 25,
'regular' => 55,
'long' => 100
);
/**
* Sets the length for the excerpt,
* then it adds the WP filter
* And automatically calls the_excerpt();
*
* @param string $new_length
* @return void
* @author Baylor Rae'
*/
public static function length($new_length = 55) {
Excerpt::$length = $new_length;
add_filter('excerpt_length', 'Excerpt::new_length', 999);
Excerpt::output();
}
// Tells WP the new length
public static function new_length() {
if( isset(Excerpt::$types[Excerpt::$length]) )
return Excerpt::$types[Excerpt::$length];
else
return Excerpt::$length;
}
// Echoes out the excerpt
public static function output() {
the_excerpt();
}
}
// An alias to the class
function my_excerpt($length = 55) {
Excerpt::length($length);
}
