以下是我的一些代码：

class proposal {

function __construct() {
    add_menu_page(\'Topic Proposal\', \'Topic Proposal\', \'read\', \'topic_proposal\', array(&$this, \'writer_page\'), \'dashicons-welcome-add-page\');
}

public function load_menu() {
    echo \'EHY\';
}

public function writer_page() {
    ?>
        <h1>Topic Proposal</h1>
    <?php
}

public function editor_page() {
    ?>
        <h1>Topic Proposal</h1>
    <?php
}

}

add_action( \'admin_init\', function(){return new proposal();});
