Eloquent - > first（）if - > exists（）

Question

I want to get the first row in table where condition matches:

User::where('mobile', Input::get('mobile'))->first()

It works well, but if the condition doesn't match, it throws an Exception:

ErrorException
Trying to get property of non-object

Currently I resolve it like this:

if (User::where('mobile', Input::get('mobile'))->exists()) {
    $user = User::where('mobile', Input::get('mobile'))->first()
}

Can I do this without running two queries?

Answer 1

Note: The first() method doesn't throw an exception as described in the original question. If you're getting this kind of exception, there is another error in your code.

The correct way to user first() and check for a result:

$user = User::where('mobile', Input::get('mobile'))->first(); // model or null
if (!$user) {
   // Do stuff if it doesn't exist.
}

Other techniques (not recommended, unnecessary overhead):

$user = User::where('mobile', Input::get('mobile'))->get();

if (!$user->isEmpty()){
    $firstUser = $user->first()
}

or

try {
    $user = User::where('mobile', Input::get('mobile'))->firstOrFail();
    // Do stuff when user exists.
} catch (ErrorException $e) {
    // Do stuff if it doesn't exist.
}

or

// Use either one of the below. 
$users = User::where('mobile', Input::get('mobile'))->get(); //Collection

if (count($users)){
    // Use the collection, to get the first item use $users->first().
    // Use the model if you used ->first();
}

Each one is a different way to get your required result.
