在看到一些Demo教程页面的时候,突然想到一个问题,在做Demo的时候往往需要插入一些单独的与Demo相关的样式,这些样式是如何添加的呢?
因为接触WordPress不久,起初我只是联想到在自定义博客的时候搜索到的模板页面(参考给你的wordpress新建独立的tag页面),本博客的Archives、Categories等页面都是采用这种方法实现的,但后来仔细一想觉得这种方法太不切实际了,那岂不是要给每个页面都添加一个模板页面。
然后,我又想WordPress的编辑/发表文章的HTML编辑框可否添加样式<style>
,试了下发现确实可以,不过自然地添加的样式是追加在所跟随文本的后方,而不是在<head>
内。
有没有一种方法可以在<head>
中添加一小段为本文章而单独设定的样式呢,而又类似在编辑框中那样可以方面的添加样式内容? 经过万能的Google搜索,找到一篇与我的问题非常契合的博客Custom CSS Per Post。文中作者提供了两个可以选择的方法,两者都可以在主题的function.php中添加少量代码实现,而无需为止安装额外的插件。
第一种方法,是创建一个特殊的目录如custom_style,若某篇文章需要单独的样式设定,就在该目录下放置一个名为style-XXXX.css的样式文件,其中XXXX为文章的ID。该方法需要在function.php添加如下代码
function artStyle() { global $post; if (is_single()) { // 如果是详细文章页面 $currentID = $post->ID; // 获取文章ID $serverfilepath = TEMPLATEPATH.'/art-direction/style-'.$currentID.'.css'; // 样式文件搜索路径 $publicfilepath = get_bloginfo('template_url'); $publicfilepath .= '/art-direction/style-'.$currentID.'.css'; if (file_exists($serverfilepath)) { // 假设该文件存在 echo "<link rel='stylesheet' type='text/css' href='$publicfilepath' media='screen' />"."\n"; } } } add_action('wp_head', 'artStyle'); // 在加载head的时候执行artStyle的动作
因为我不会PHP,所以对某些函数的具体工作不是非常清楚,只能凭着个人想法加以解释(个人觉得有必要好好学学PHP)。但是这个方法明显的一个缺陷是,每篇文章都需要进行一次文件查询的动作,这点让一些完美主义者(包括博主我本人)无法接受。所幸,作者又给出了另外一种方法,看到这个方法,我真是有一种踏破铁鞋无觅处,得来全不费工夫的感觉。该方法的代码同样添加到function.php中,如下所示:
//Custom CSS Widget add_action('admin_menu', 'custom_css_hooks'); add_action('save_post', 'save_custom_css'); add_action('wp_head','insert_custom_css'); function custom_css_hooks() { add_meta_box('custom_css', 'Custom CSS', 'custom_css_input', 'post', 'normal', 'high'); add_meta_box('custom_css', 'Custom CSS', 'custom_css_input', 'page', 'normal', 'high'); } function custom_css_input() { global $post; echo '<input type="hidden" name="custom_css_noncename" id="custom_css_noncename" value="'.wp_create_nonce('custom-css').'" />'; echo '<textarea name="custom_css" id="custom_css" rows="5" cols="30" style="width:100%;">'.get_post_meta($post->ID,'_custom_css',true).'</textarea>'; } function save_custom_css($post_id) { if (!wp_verify_nonce($_POST['custom_css_noncename'], 'custom-css')) return $post_id; if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) return $post_id; $custom_css = $_POST['custom_css']; update_post_meta($post_id, '_custom_css', $custom_css); } function insert_custom_css() { if (is_page() || is_single()) { if (have_posts()) : while (have_posts()) : the_post(); $custom_css = get_post_meta(get_the_ID(), '_custom_css', true); if (!empty($custom_css)) echo '<style type="text/css">'.$custom_css.'</style>'; endwhile; endif; rewind_posts(); } }
2011.3.5 更新:当custom_css为空的时候,不添加样式标记。
试试看看吧,在发表帖子的页面下面会出现一个custom css的文本框。
