最简单的方法是通过CSS隐藏通知，如下所示：

    function hide_update_msg_non_admins(){
     if (!current_user_can( \'manage_options\' )) { // non-admin users
            echo \'<style>#setting-error-tgmpa>.updated settings-error notice is-dismissible, .update-nag, .updated { display: none; }</style>\';
        }
    }
    add_action( \'admin_head\', \'hide_update_msg_non_admins\');

您可以在函数中尝试以下代码。php

if ( current_user_can( \'manage_options\' ) ) {
} else {
echo ".update-nag , .error, .updated{ display:none; }";
}

This works for me:

add_action(\'admin_head\', \'admin_only_warnings\');

function admin_only_warnings() {
if(is_admin() && !current_user_can(\'administrator\') ) {
  echo \'<style>
    <!-- add your classes/ids below -->
    .warning, .error, .updated {display:none !important;}
    } 
  </style>\';
}
}

Try this one

function am_disable_admin_notices() {
global $wp_filter;
if (!current_user_can( \'manage_options\' )) {
    if (isset($wp_filter[\'user_admin_notices\'])) {
            unset( $wp_filter[\'user_admin_notices\']);
    }
}
add_action( \'admin_print_scripts\', \'am_disable_admin_notices\' );
