我们都知道，如果WordPress官方推送新版本的WordPress时，都会在WordPress后台顶部显示一条高亮的提醒信息，如下如所示：
下面，倡萌就来分享下，在WordPress后台顶部添加错误提醒信息或升级提醒信息 的方法，这里需要借助 admin_notices 挂钩 来实现。只需要在主题的 functions.php 中添加下面的代码样例即可：
function showMessage($message, $errormsg = false)
{
if ($errormsg) {
echo '
<div id="message" class="error">';
}
else {
echo '
<div id="message" class="updated fade">';
}
echo "
<strong>$message</strong>
</div>
";
}
function showAdminMessages()
{
showMessage("Welcome to the new WordPress theme.", true);
}
add_action('admin_notices', 'showAdminMessages'); |
function showMessage($message, $errormsg = false)
{
if ($errormsg) {
echo '
<div id="message" class="error">';
}
else {
echo '
<div id="message" class="updated fade">';
}
echo "
<strong>$message</strong>
</div>
";
}
function showAdminMessages()
{
showMessage("Welcome to the new WordPress theme.", true);
}
add_action('admin_notices', 'showAdminMessages');
