我在WP Recipies page 要在主页上强制摘录，请执行以下操作：

function my_excerpts($content = false) {
    // If is the home page, an archive, or search results
if(is_front_page() || is_archive() || is_search()) :
    global $post;
    $content = $post->post_excerpt;

// If an excerpt is set in the Optional Excerpt box
    if($content) :
        $content = apply_filters(\'the_excerpt\', $content);

// If no excerpt is set
    else :
        $content = $post->post_content;
        $excerpt_length = 55;
        $words = explode(\' \', $content, $excerpt_length + 1);
        if(count($words) > $excerpt_length) :
            array_pop($words);
            array_push($words, \'...\');
            $content = implode(\' \', $words);
        endif;
        $content = \'<p>\' . $content . \'</p>\';

    endif;
endif;

// Make sure to return the content
return $content;

}

add_filter(\'the_content\', \'my_excerpts\');
