Laravel创建多个属性

我有我的laravel电子商店，我有类似功能的产品属性，我需要创建多个属性，但我有如下错误：

"ErrorException（E_WARNING）帮助preg_replace（）：参数不匹配，模式是字符串，而替换是数组"

在这里，我将分享我的整个MVC结构。任何人都能找到解决方案来修复这个错误吗？提前感谢

我的控制器：

public function store()
{
    $attribute_values = Input::all();
    $attribute_price_values = Input::get('price');
    $image = Input::file('image');
    $attribute_id = Input::get('attribute_id');
    if($attribute_id <= 0) {
        return Redirect::back();
    }
    $attributes_data = Attribute::where('id', '=', $attribute_id)->get(array('price_mode'))->toArray();
    $attr_price = $attributes_data[0]; 
    foreach($attribute_values as $k => $v) {
        $insert_data = new AttributeValues;
        $insert_data->attribute_id = $attribute_id;
        $data_validation['attribute_id'] = $insert_data->attribute_id;
        $insert_data->value = $v;
        $data_validation['value'] = $insert_data->value;
        $validator = Validator::make($data_validation, AttributeValues::$rules);
        if ($validator->fails()) {
            $messages = $validator->messages();
            return Redirect::back()->withErrors($validator)->withInput();
        } else{
            //check the price flag
            //upload image in  directory
            // $attribute_value_image = $image[$k];
            if(isset($attribute_value_image) && $attribute_value_image != '') {
                $filename = time(). '_' .$attribute_value_image->getClientOriginalName();
                if (!file_exists(public_path() . DIRECTORY_SEPARATOR . 'uploads' . DIRECTORY_SEPARATOR . 'attribute_values' . DIRECTORY_SEPARATOR . 'original' . DIRECTORY_SEPARATOR .
                 $insert_data->attribute_id)) {
                    mkdir(public_path() . DIRECTORY_SEPARATOR . 'uploads' . DIRECTORY_SEPARATOR . 'attribute_values' . DIRECTORY_SEPARATOR . 'original' . DIRECTORY_SEPARATOR .
                        $insert_data->attribute_id, 0777, true);
                }
                if (!file_exists(public_path() . DIRECTORY_SEPARATOR . 'uploads' . DIRECTORY_SEPARATOR . 'attribute_values' . DIRECTORY_SEPARATOR . 'small' . DIRECTORY_SEPARATOR .
                     $insert_data->attribute_id)) {
                    mkdir(public_path() . DIRECTORY_SEPARATOR . 'uploads' . DIRECTORY_SEPARATOR . 'attribute_values' . DIRECTORY_SEPARATOR . 'small' . DIRECTORY_SEPARATOR .
                     $insert_data->attribute_id, 0777, true);
                }
                $original_image = Image::make($attribute_value_image->getRealPath())->save(public_path() . DIRECTORY_SEPARATOR . 'uploads' . DIRECTORY_SEPARATOR . 'attribute_values' . DIRECTORY_SEPARATOR . 'original' . DIRECTORY_SEPARATOR . $insert_data->attribute_id. DIRECTORY_SEPARATOR . $filename);
                $resized_small_image = Image::make($attribute_value_image->getRealPath())->resize(120, 44)->save(public_path() . DIRECTORY_SEPARATOR . 'uploads' . DIRECTORY_SEPARATOR . 'attribute_values' . DIRECTORY_SEPARATOR . 'small' . DIRECTORY_SEPARATOR . $insert_data->attribute_id . DIRECTORY_SEPARATOR . $filename);
                $fileFrom = public_path() . DIRECTORY_SEPARATOR . 'uploads' . DIRECTORY_SEPARATOR . 'attribute_values' . DIRECTORY_SEPARATOR . 'original' . DIRECTORY_SEPARATOR .
                $insert_data->attribute_id . DIRECTORY_SEPARATOR . $filename;
                $insert_data->image = $filename;
            }
            if($attr_price['price_mode'] == 'Common') {
                $insert_data->price = $attribute_price_values[$k];
            }
            $insert_data->save();
        }
    }
    if(Input::get('stay') == 1){
        return Redirect::back();
    } else {
        return Redirect::route('backend.attribute_values.index');
    }
}

我的型号：

<?php
class AttributeValues extends 'Eloquent {
protected $table = 'attribute_values';
protected $fillable = ['attribute_id','value', 'image', 'price','color'];
public static $rules = array(
    'attribute_id' => 'required',
    'value' => 'required',
);
public static $pricerules = array(
    'value' => 'required',
    'price' => 'required|regex:/^'d*('.'d{2})?$/'
);
public static $edit_rules = array(
    'value' => 'required'
);
  public function attribute(){
    return $this->belongsTo('Attribute');
  }
}

这里我使用attribute_id=2，颜色属性，它使用一些Jquery来隐藏和显示属性id何时为2颜色属性，所以它总是显示错误，比如"ErrorException（E_WARNING）帮助preg_replace（）：参数不匹配，模式是字符串，而替换是数组""
