How to write Laravel eloquent query inside model function? - laravel-5

Question

Actually I don't know how to retrieve data from db using function and query inside model .Please help me what should i add inside model function.
Here is controller
public function checkAdmin(Request $request){
$data = array();
$data['email'] = $request->email;
$data['password'] = $request->password;
$found = AdminModel::checkAdmin($data);
if($found == TRUE){
echo "found";
}
else{
echo "sorry";
}
}
Here is the Model Function
public static function checkAdmin($data){
$found = $this->where('email',$data['email'])->where('password',$data['password'])->first();
return $found;
}

Answer 1

What is the purpose of the checkAdmin function? Are you trying to validate a login? If yes, Laravel does this for you out of the box with the Auth::attempt method:
$credentials = $request->only('email', 'password');
if (Auth::attempt($credentials)) {
// Authentication passed...
return redirect()->intended('dashboard');
}
https://laravel.com/docs/5.7/authentication#authenticating-users
However to answer your question, you could do so like this:
$userFound = AdminModel::where(['email' => $request->email, 'password] => $request->password)->count();
if($userFound){
echo "found";
}
else{
echo "sorry";
}
