Laravel update only single row

I am having a trouble updating my single record in database with laravel.

When i run this method and give requestparams only "name" then the other fields are going to be blank in database. How to keep the values that are not specified in the requestparams?.

public function update(Request $request, $id)
{
    $user = User::find($id);
    if(!is_null($user)){
        $user->name = $request->input('name');
        $user->email = $request->input('email');
        $user->password = $request->input('password');
        $user->save();
    }else{
        $data = array('msg' => 'The user, you want to update, does not exist', 'error' => true);
        echo json_encode($data);
    }
}

You can use the update method with the request input directly. This will only update the inputs provided.

$user->update($request->only(['name', 'email', 'password']));

Few things to note though. You're trying to update the password directly from the input. Which is a bad practise and might be wrong since laravel uses bcrypt by default to store passwords. Secondly make sure you set the $fillable property in the model to protect against mass-assignment.

protected $fillable = [
    'name', 'email', 'password'
];

Also you can use a mutator to hash the password like so.

public function setPasswordAttribute($value)
{
    $this->attributes['password'] = bcrypt($value);
}

Laravel - Update only selected data, You need to add $id inside your query, This is the reason it updates your whole row: DB::table('schedules')->where(  How do i update only one column per row satisfy the conditions Posted 2 years ago by Shawdow Below query executes the condition of join and gives the result of TWO id's and gets updated to closed for both id

You can do that by something like this with default values (remember about $fillable in your model).

$user->update([
    'name' =>  $request->input('name', $user->name),
    'email' => $request->input('email', $user->password),
    'password' => $request->input('password', $user->password),
]);

Set your mutator in model to Hash password. :)

Good luck mate :D

How do i update only one column per row satisfy the conditions, How do i update only one column per row satisfy the conditions. Posted 2 I need to update only one ID. What is the or better use Eloquent Laravel’s Eloquent ORM has a method called fill which accepts an array and will update the database with new values for only the fields passed in. The nice thing about the fill method is that it automatically preserves values that are already stored in the database if you don’t want to update every field when doing a PUT request.

Just check if request data is empty, for example:

$user->name = empty($request->name) ? $user->name : $request->name;
$user->email = empty($request->email) ? $user->email : $request->email;
$user->password = empty($request->password) ? $user->password : bcrypt($request->password);
