将此代码添加到functions.php 要为用户添加通知，请使用subscriber 在其配置文件和仪表板管理页面上的角色。

function wpse239290_user_welcome_notice() {
    // Make sure that the user is assigned to the subscriber role, specifically.
    // Alternatively, capabilities can be checked with current_user_can(), but roles are not supposed to be checked this way.
    $user = wp_get_current_user();
    if ( ! in_array( \'subscriber\', $user->roles ) ) {
        return;
    }

    // Make sure the profile or dashboard screens are being viewed.
    $screen = get_current_screen();
    if ( ! $screen || ( \'profile\' !== $screen->id && \'dashboard\' !== $screen->id ) ) {
        return;
    }

    // Show a friendly green notice, and allow it to be dismissed (it will re-appear if the page is reloaded though).
    $class = \'notice notice-success is-dismissible\';

    // Customize the HTML to  fit your preferences.
    $message = \'<p>Looking for the <a href="http://example.com/form">Example Form</a></p>\';

    printf( \'<div class="%1$s"><div class="subscriberProfile">%2$s</div></div>\', $class, $message ); 
}
add_action( \'admin_notices\', \'wpse239290_user_welcome_notice\' );
