Laravel检查是否存在记录 [英] Laravel checking if record exists
本文介绍了Laravel检查是否存在记录的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
$ user = User :: where('email','=',Input :: get('email'));
我在这里可以查看 $ user
有记录?
解决方案
这取决于您是否要与用户协同工作,或仅检查是否存在。 / p>
如果要使用用户对象(如果存在):
$ user = User :: where('email','=',Input :: get('email')) - > first();
if($ user === null){
//用户不存在
}
如果您只想检查
if(User :: where('email' ,'=',Input :: get('email')) - > count()> 0){
//用户发现
}
甚至更好的
if(User :: where('email','=',Input :: get('email')) - > exists()){
// user found
}
New to laravel, so excuse the newbie question but how do I find if a record exists?
$user = User::where('email', '=', Input::get('email'));
What would I do here to see if $user
has a record?
解决方案
It depends if you want to work with the user afterwards or only check if one exists.
If you want to use the user object if it exists:
$user = User::where('email', '=', Input::get('email'))->first();
if ($user === null) {
// user doesn't exist
}
And if you only want to check
if (User::where('email', '=', Input::get('email'))->count() > 0) {
// user found
}
Or even nicer
if (User::where('email', '=', Input::get('email'))->exists()) {
// user found
}
