validation - 为什么 cakephp 抛出错误？

Question

我正在尝试在控制器中创建验证，以在关系表中检查他们发送账单的人的用户名，并且在站点将发票保存在数据库中之前，姓名是否存在于活动字段中

关系表是id, partyone, partytwo, active, expirydate. 验证抛出此错误解析错误：语法错误，意外的 T_OBJECT_OPERATOR

 public function add(){

 if($this->request->is('post')){
 $this->Invoice->set($this->request->data);
 if(this->Invoice->validates(array('fieldList'=>array('Relationship.partyone','Relationship.active')){
  $this->Invoice->create(); 
 if ($this->Invoice->saveAll($this->request->data,array('validate'=>false))) 
 { 
  $this->Session->setFlash('The invoice has been saved');  
} else { 
      $this->Session->setFlash('The invoice could not be saved. Please, try again.');
      $errors=$this->Invoice->validationErrors;
    }

  } 

  }

Answer 1

看来您之前忘记了美元符号this。

if(this->Invoice->validates(array('fieldList'=>array('Relationship.partyone','Relationship.active')){

应该

if($this->Invoice->validates(array('fieldList'=>array('Relationship.partyone','Relationship.active')){
