从静态方法调用"admin_notices“钩子

Question

试图从静态函数调用"admin_notices“钩子。没有输出。当正常调用同一个钩子的时候。

use Awraq\Init;
use Awraq\Notice;

/**
 * Initialize the activation works of the plugin.
 */
function awraq_activate_plugin()
{

    /* NOT WORKING */
    Notice::error('Activation failed');

    
    /* WORKING */

    //add_action('admin_notices', 'simplefunction');
}

register_activation_hook(__FILE__, 'awraq_activate_plugin');



function simplefunction()
{
    echo '
        Activation failed';
}

类

namespace Awraq;

if (!defined('ABSPATH')) exit;

class Notice
{
    private static $class = '';
    private static $msg = '';

    public static function error($msg = 'error', $is_dismissible = TRUE)
    {
        self::$class = ($is_dismissible == TRUE) ? 'notice notice-error is-dismissible' : 'notice notice-error';
        self::$msg = __($msg, AWRAQ_TEXT_DOMAIN);
        add_action('admin_notices', array(__CLASS__, 'awraq_notice'));
    }

    public static function warning($msg = 'warning', $is_dismissible = TRUE)
    {
        self::$class = ($is_dismissible == TRUE) ? 'notice notice-warning is-dismissible' : 'notice notice-warning';
        self::$msg = __($msg, AWRAQ_TEXT_DOMAIN);
        add_action('admin_notices', array(__CLASS__, 'awraq_notice'));
    }

    public static function success($msg = 'success', $is_dismissible = TRUE)
    {
        self::$class = ($is_dismissible == TRUE) ? 'notice notice-success is-dismissible' : 'notice notice-success';
        self::$msg = __($msg, AWRAQ_TEXT_DOMAIN);
        add_action('admin_notices', array(__CLASS__, 'awraq_notice'));
    }

    public static function info($msg = 'info', $is_dismissible = TRUE)
    {
        self::$class = ($is_dismissible == TRUE) ? 'notice notice-info is-dismissible' : 'notice notice-info';
        self::$msg = __($msg, AWRAQ_TEXT_DOMAIN);
        add_action('admin_notices', array(__CLASS__, 'awraq_notice'));
    }

    public static function  awraq_notice()
    {

        $class  = self::$class;
        $msg    = self::$msg;

        if ($class == '' and $msg == '') {
            return;
        }

        printf('%2$s', esc_attr($class), esc_html($msg));
    }
}

Answer 1

通过做两件事解决了问题

• 移除主调用

/**
 * Initialize the activation works of the plugin.
 */
function awraq_activate_plugin()
{
    //removed 
}

register_activation_hook(__FILE__, 'awraq_activate_plugin');

添加了对"plugins_loaded“的调用

/**
 * Initialize the plugin.
 */
function awraq_init_plugin()
{
    if (Init::activate() != TRUE) {
        deactivate_plugins(plugin_basename(__FILE__));
        //added below
        Notice::error('Plugin got Deactivated. Please check the dependencies.', true);
    }
}
add_action('plugins_loaded', 'awraq_init_plugin');

• 并且在类中删除了带有完整命名空间和类-private static $globalScopeName = 'Awraq\Base\Notice';的D9，因为它将从外部调用。

namespace Awraq\Base;

if (!defined('ABSPATH')) exit;

class Notice
{
    private static $globalScopeName = 'Awraq\Base\Notice';
    private static $class = '';
    private static $msg = '';

    public static function error($msg = 'error', $is_dismissible = TRUE)
    {
        self::$class = ($is_dismissible == TRUE) ? 'notice notice-error is-dismissible' : 'notice notice-error';
        self::$msg = __($msg, AWRAQ_TEXT_DOMAIN);
        add_action('admin_notices', array(self::$globalScopeName, 'awraq_notice'));
    }

    public static function warning($msg = 'warning', $is_dismissible = TRUE)
    {
        self::$class = ($is_dismissible == TRUE) ? 'notice notice-warning is-dismissible' : 'notice notice-warning';
        self::$msg = __($msg, AWRAQ_TEXT_DOMAIN);
        add_action('admin_notices', array(self::$globalScopeName, 'awraq_notice'));
    }

    public static function success($msg = 'success', $is_dismissible = TRUE)
    {
        self::$class = ($is_dismissible == TRUE) ? 'notice notice-success is-dismissible' : 'notice notice-success';
        self::$msg = __($msg, AWRAQ_TEXT_DOMAIN);
        add_action('admin_notices', array(self::$globalScopeName, 'awraq_notice'));
    }

    public static function info($msg = 'info', $is_dismissible = TRUE)
    {
        self::$class = ($is_dismissible == TRUE) ? 'notice notice-info is-dismissible' : 'notice notice-info';
        self::$msg = __($msg, AWRAQ_TEXT_DOMAIN);
        add_action('admin_notices', array(self::$globalScopeName, 'awraq_notice'));
    }

    public static function  awraq_notice()
    {

        $class  = self::$class;
        $msg    = self::$msg;

        if ($class == '' and $msg == '') {
            return;
        }

        printf('%2$s', esc_attr($class), esc_html($msg));
    }
}
