这是我的代码：

class BWP_PostGrid {

    function __construct () {
        add_action(\'admin_init\', array($this, \'plugin_initializer\'));
        add_shortcode(\'bwp_post_grid\', array($this, \'shortcode_callback\'));
        add_action(\'wp_enqueue_scripts\', array($this, \'enqueue_scripts\'));
        add_action(\'admin_enqueue_scripts\', array($this, \'admin_enqueue_scripts\'));
        add_action(\'wp_ajax_bwp_post_grid_get_data\', array($this, \'bwp_post_grid_get_data\'));
        add_action(\'wp_ajax_nopriv_bwp_post_grid_get_data\', array($this, \'bwp_post_grid_get_data\'));
    }

    function plugin_initializer() {
    }

    function shortcode_callback($shortcode_attributes) {
    }

    function enqueue_scripts() {
        wp_enqueue_style(\'bwp-post-grid-styles\', plugins_url(\'bwp-styles.css\', __FILE__), false);
        wp_enqueue_script(\'bwp-post-grid-js\', plugins_url(\'bwp-main.js\', __FILE__), false);
    }

    function admin_enqueue_scripts() {
    }

    function bwp_post_grid_get_data() {
    }
}

new BWP_PostGrid();

我还检查了apache错误日志。。。没有错误。
