我正在使用PHP和laravel框架创建一个Web应用程序。我的代码中有以下类。使用PHP和laravel框架在MySql数据库中存储对象数组
class ReportField extends Model
{
//
public $name;
public $quantity;
public $unitCost;
public $totalCost;
public $estimation;
}
我使用序列化将这些对象的数组写入数据库。
$fieldsList=array();
foreach($items as $item){
if($item->sale_type == 1){
$reportField=new ReportField();
$reportField->name=$item->item_name;
$reportField->unitCost=$item->unit_cost;
array_push($fieldsList,serialize($reportField));
}
}
$gpForecast=new GPForecast();
$gpForecast->project_id=$project_id;
$gpForecast->fieldList=(serialize($fieldsList));
$gpForecast->save();
现在反序列化之后,我想将数组中的那些对象转换回RecordField对象。
$gpForecast=GPForecast::all()->first(); //here i read one of array i write to database
$fieldList=unserialize($gpForecast->fieldList);
foreach($fieldList as $field){
echo $field->name;
}
但后来我得到错误Trying to get property of non-object
那么我该如何纠正这个问题?
难道你不应该为你的模型属性使用'protected $ fillable'吗? – haakym
