将WordPress文章内容注册为短代码

代码来自postx,flatsome主题也有类似的。

可能需要注册文章?:

class Saved_Templates {
    public function __construct() {
        $this->templates_post_type_callback();
        add_action('admin_head', array($this, 'custom_head_templates'));

        add_action('manage_ultp_templates_posts_custom_column', array($this, 'templates_table_content'), 10, 2);
    }

注册短代码:

class Shortcode {
    public function __construct() {
        // add_shortcode('gutenberg_post_blocks', array($this, 'shortcode_callback'));
        add_shortcode('postx_template', array($this, 'shortcode_callback'));
    }

    // Shortcode Callback
    function shortcode_callback( $atts = array(), $content = null ) {
        extract(shortcode_atts(array(
         'id' => ''
        ), $atts));

        $id = is_numeric( $id ) ? (float) $id : false;

        if ($id) {
            $content = '';
            if (!isset($GLOBALS['wp_scripts']->registered['ultp-script'])) {
                ultimate_post()->register_scripts_common();
            }
            $css = ultimate_post()->set_css_style($id, true);
            $content_post = get_post($id);
            if ($content_post) {
                if ($content_post->post_status == 'publish' && $content_post->post_password == '') {
                    $content = $content_post->post_content;
                    $content = do_blocks($content);
                    $content = do_shortcode($content);
                    $content = str_replace(']]>', ']]>', $content);
                    $content = preg_replace('%<p> \s*</p>%', '', $content);
                    $content = preg_replace('/^(?:<br\s*\/?>\s*)+/', '', $content);
                    return $css.'<div class="ultp-shortcode" data-postid="'.$id.'">' . $content . '</div>';
                }
            }
        }
        return '';
    }
    
}

启用:

add_action('init', 'ultp_templates_init');
function ultp_templates_init() {
  new Saved_Templates();//注册模板文章类型
  new Shortcode();//注册短代码
}
