这是我的摘录代码.

 // Generate custom excerpt length
function wpbx_excerpt_length($length) {
    return 300;
}
add_filter('excerpt_length', 'wpbx_excerpt_length');

如何允许类似<a> 

Here is my excerpt code.

// Generate custom excerpt length
function wpbx_excerpt_length($length) {
    return 300;
}
add_filter('excerpt_length', 'wpbx_excerpt_length');

How do I allow html like <a>

如果需要,可以添加更多标签到$allowed_tags = ...

 function _20170529_excerpt($text) {
$raw_excerpt = $text;
if ( '' == $text ) {
    //Retrieve the post content. 
    $text = get_the_content('');

    //Delete all shortcode tags from the content. 
    $text = strip_shortcodes( $text );

    $text = apply_filters('the_content', $text);
    $text = str_replace(']]>', ']]&gt;', $text);

    $allowed_tags = '<a>,<b>,<br><i>'; 
    $text = strip_tags($text, $allowed_tags);

    $excerpt_word_count = 55; /*** MODIFY THIS. change the excerpt word count to any integer you like.***/
    $excerpt_length = apply_filters('excerpt_length', $excerpt_word_count); 

    $excerpt_end = '[...]'; /*** MODIFY THIS. change the excerpt endind to something else.***/
    $excerpt_more = apply_filters('excerpt_more', ' ' . $excerpt_end);

    $words = preg_split("/[\n\r\t ]+/", $text, $excerpt_length + 1, PREG_SPLIT_NO_EMPTY);
    if ( count($words) > $excerpt_length ) {
        array_pop($words);
        $text = implode(' ', $words);
        $text = $text . $excerpt_more;
    } else {
        $text = implode(' ', $words);
    }
}
return apply_filters('wp_trim_excerpt', $text, $raw_excerpt);
}

Add more tags if you need into $allowed_tags = ...

function _20170529_excerpt($text) {
$raw_excerpt = $text;
if ( '' == $text ) {
    //Retrieve the post content. 
    $text = get_the_content('');

    //Delete all shortcode tags from the content. 
    $text = strip_shortcodes( $text );

    $text = apply_filters('the_content', $text);
    $text = str_replace(']]>', ']]&gt;', $text);

    $allowed_tags = '<a>,<b>,<br><i>'; 
    $text = strip_tags($text, $allowed_tags);

    $excerpt_word_count = 55; /*** MODIFY THIS. change the excerpt word count to any integer you like.***/
    $excerpt_length = apply_filters('excerpt_length', $excerpt_word_count); 

    $excerpt_end = '[...]'; /*** MODIFY THIS. change the excerpt endind to something else.***/
    $excerpt_more = apply_filters('excerpt_more', ' ' . $excerpt_end);

    $words = preg_split("/[\n\r\t ]+/", $text, $excerpt_length + 1, PREG_SPLIT_NO_EMPTY);
    if ( count($words) > $excerpt_length ) {
        array_pop($words);
        $text = implode(' ', $words);
        $text = $text . $excerpt_more;
    } else {
        $text = implode(' ', $words);
    }
}
return apply_filters('wp_trim_excerpt', $text, $raw_excerpt);
}

您还可以添加摘录的RTF编辑器,在插件文件或主题的function.php文件中添加以下代码,您将能够看到摘录的HTML编辑器.此外,它还将以HTML格式呈现摘录. #欢呼声

我已从某处复制了此文件,但不记得源了.我在所有项目中都使用了它,并且它正在工作.

You can add rich text editor for excerpts as well, add below code in plugin file or theme's function.php file and you'll be able to see HTML editor for excerpts. Moreover, it'll render excerpts in HTML format as well. #cheers

I've copied this from somewhere but don't remember the source. I'm using this in my all projects and it's working.
