如上,怎么将$title 像$query一样,在函数内部使用?
$result = UserMenus::with(['menu'=>function($query){
$query->where('title',$title);
}])->where('user_id',$userId)->first();

<code>php</code><code>$result = UserMenus::with(['menu'=>function($query) use($title){ $query->where('title',$title); }])->where('user_id',$userId)->first(); </code>
<code>$result = UserMenus::with( [ 'menu'=>function($query){ global $title; $query->where('title',$title); } ])->where('user_id',$userId)->first(); </code>
话说PHP 有全局函数,你加global 不行吗?
