我有一个包含公共财产My_Admin
$options
我有一个需要访问My_Notices
属性的子类$options
。
如果在子课程中,我将parent::__construct()
投入到子类的__construct()
中,我可以访问$options
但是它会复制整个输出父类的。换句话说,我在同一页面上得到两个html页面输出,因为调用parent::_construct()
的子类的实例化。
我已经尝试在我的子结构中声明$options
,如public function __construct($options)
,但它告诉我:
Warning: Missing argument 1 for My_Notices::__construct()
**编辑**
以下是课程的细分:
class My_Admin
{
private $sections;
protected $settings;
protected $defaults;
public $options;
public function __construct()
{
$this->settings = array();
$this->get_settings();
$this->defaults = array( /* stuff here */ );
$this->sections = array( /* stuff here */ );
add_filter('plugin_action_links', array($this, 'pluginpage'), 10, 2);
add_action('admin_menu', array($this, 'menu'));
add_action('admin_enqueue_scripts', array($this, 'enqueue'));
add_action('admin_init', array($this, 'deregister'), 20);
add_action('wp_ajax_my_save', array($this, 'save'));
if(!get_option('my_options')) $this->initialize();
$this->options = get_option('my_options');
}
}
class My_Notices extends My_Admin
{
public function __construct()
{
add_action('admin_notices', array($this, 'baseconfig'));
add_action('admin_init', array($this, 'baseignore'));
}
public function baseconfig(){
global $pagenow;
$uid = get_current_user_id();
/* I NEED TO ACCESS $options HERE */
if(!$this->options['base1'] || !$this->options['bs1name'])
{
if(!get_user_meta($uid, 'my_notice'))
{
}
}
}
}

根据您的意见,您需要在没有打印的情况下致电您的父母。您需要使用ob_start
和ob_end_clean
,但是您应该看看您的逻辑是否正确,因为如果父类打印文本不是最好的。
class My_Notices extends My_Admin {
public __construct(){
ob_start(); // prevents prints.
parent::__construct();
ob_end_clean(); // clear the capture
// Your code here....
<强>已更新强>: 您也可以检查它是否是父项,然后打印:
class My_Admin
{
private $sections;
protected $settings;
protected $defaults;
public $options;
public function __construct()
{
$this->settings = array();
$this->get_settings();
$this->defaults = array( /* stuff here */ );
$this->sections = array( /* stuff here */ );
if( !is_subclass_of($this, 'My_Admin' ) ) { // Is the parent
add_filter('plugin_action_links', array($this, 'pluginpage'), 10, 2);
add_action('admin_menu', array($this, 'menu'));
add_action('admin_enqueue_scripts', array($this, 'enqueue'));
add_action('admin_init', array($this, 'deregister'), 20);
add_action('wp_ajax_my_save', array($this, 'save'));
}
if(!get_option('my_options')) $this->initialize();
$this->options = get_option('my_options');
}
public function get_settings(){}
public function initialize(){}
}
class My_Notices extends My_Admin
{
public function __construct()
{
parent::__construct();
add_action('admin_notices', array($this, 'baseconfig'));
add_action('admin_init', array($this, 'baseignore'));
}
}

为避免您的双重创作,这可能是您必须采取的路线:
将这些添加到My_Admin类:
制作private static $self;
财产。
在__construct()
方法中添加self::$self = &$this;
制作方法:
public static getInstance(){
return $self;
}
在My_Notices中添加此选项,您需要访问options属性:
$my_admin = My_Admin::getInstance();
$my_admin->options;
