我已经查看了这篇文章（Multiple excerpt lengths in wordpress），但很明显，WordPress的版本很多时候已从我们现在的位置删除了很多次。我也需要多个不同长度的长度，但标签被剥离。我没有使用＆＃34;摘录＆＃34;帖子上的框，所以它需要连接内容本身。我非常喜欢该页面上的建议答案，包括＆＃34;短＆＃34;，＆＃34;常规＆＃34;和＃34;长＆＃34;，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，以与其余4个帖子不同的方式显示组中的第一个帖子。我只在第一篇文章末尾包括代码，因为其他代码不包含摘录。
这就是我现在拥有的。也许有人可以看到我弄乱的地方：
的functions.php 课程摘录{
// 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);
}
