Laravel Checking If a Record Exists

Question

I am new to Laravel. Please excuse the newbie question but how do I find if a record exists?

$user = User::where(\'em         


        

Answer 1

if (User::where('email', Input::get('email'))->exists()) {
    // exists
}

Answer 2

if ($u = User::where('email', '=', $value)->first())
{
   // do something with $u
   return 'exists';
} else {
  return 'nope';
}

would work with try/catch

->get() would still return an empty array

Answer 3

Created below method (for myself) to check if the given record id exists on Db table or not.

private function isModelRecordExist($model, $recordId)
{
    if (!$recordId) return false;

    $count = $model->where(['id' => $recordId])->count();

    return $count ? true : false;
}

// To Test
$recordId = 5;
$status = $this->isModelRecordExist( (new MyTestModel()), $recordId);

Home It helps!

Answer 4

you can use laravel validation .

But this code is also good:

$user = User::where('email',  $request->input('email'))->count();

if($user > 0)
{
   echo "There is data";
}
else
   echo "No data";

Answer 5

In laravel eloquent, has default exists() method, refer followed example.

if(User::where('id', $user_id )->exists()){ // your code... }

Answer 6

In your Controller

$this->validate($request, [
        'email' => 'required|unique:user|email',
    ]); 

In your View - Display Already Exist Message

@if (count($errors) > 0)
    <div class="alert alert-danger">
        <ul>
            @foreach ($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif
