将数组传递给雄辩模型的静态方法

Question

I'm using Laravel and I have a need to pass an associative array to a static function in an eloquent model.

class MyClass extends Eloquent\Model
{
    static function scopeRegister($input) {
        return $input['key1'];
    }
}

Running with Tinker, here is my input:

$input = array('key1'=>'value', 'key2'=>'value', 'key3'=> 'value', 'key4'=>'value');

When I try it, though, I'm getting an error:

PHP error: Cannot use object of type Illuminate\\Database\\Eloquent\\Builder as array

And when I type-hint array:

class MyClass extends Eloquent\Model
{
    static function scopeRegister(array $input) {
        return $input['key1'];
    }
}

I get the following error:

Argument 1 passed to App\\KeywordGeotarget::scopeRegister() must be of the type array, object given

What's happening here and how can I access the values defined in the array from the static method within the model?

---

EDIT: I'm just using tinker right now to test this but here is the code I'm using to call the method:

php artisan tinker
>> $input = array('key1'=>'value','key2'=>'value','key3'=>'value', 'key4'=>'value');
>> App\MyClass::register($input);

Answer 1

Since it's a scope, you need to add a $query as the first parameter and then do something like this:

static function scopeRegister($query, array $input)
{
    return $query->where($input['key1']);
}

If you just want to have a method and you don't want to use it as a local scope, just rename the method (remove scope part):

static function register(array $input)

Answer 2

Your understanding for the adding query scope is wrong I guess you need to go through documentation I think. Check it over here. The scopes represents the query builder properties and you can't get builder class properties as array. You should use it like this.

class MyClass extends Eloquent\Model
{
    public function scopeRegister($query) {

        return $query->where(// perform your where here);

    }
}

You are defining an eloquent scope. Scopes do not work with arrays, but with queries.

You can read more about how to declare and use scopes here https://laravel.com/docs/5.5/eloquent#local-scopes

If you want to call register() like you did in the tinker example, do this instead (just remove the scope):

class MyClass extends Eloquent\Model
{
    static function register(array $input) {
        return $input['key1'];
    }
}
