これが私の抜粋コードです.

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

<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>

必要に応じて$allowed_tags = ...

にタグを追加します

 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);
}

抜粋用のリッチテキストエディターを追加したり、プラグインファイルまたはテーマのfunction.phpファイルに以下のコードを追加したりすると、抜粋用のHTMLエディターが表示されます.さらに、抜粋もHTML形式でレンダリングします. #cheers

これをどこかからコピーしましたが、ソースを覚えていません.私はこれをすべてのプロジェクトで使用しており、機能しています.

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.
