我有我的laravel电子商店，我有类似产品属性的功能，我需要创建多个属性，但我有如下错误：
＆＃34; ErrorException（E_WARNING） 救命 preg_replace（）：参数不匹配，pattern是一个字符串，而replacement是一个数组＆＃34;
在这里，我将分享我的整个MVC结构，任何人都可以找到解决方案来解决该错误，提前谢谢，
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');
}
}
我的模特：
<?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');
}
}

这里我使用的是attribute_id = 2，颜色属性是使用一些Jquery来隐藏和显示属性id将是2的颜色属性，所以总是显示错误像 ＆＃34; ErrorException（E_WARNING） 救命 preg_replace（）：参数不匹配，pattern是一个字符串，而replacement是一个数组＆＃34;
