如何获取cakephp中不为空的数据

Question

我正在使用 cakephp 2.6.7。我有一个名为“customers”的表，其中电子邮件在表结构中默认为“none”。我再说一遍，默认情况下它不是 NULL。因此，当电子邮件字段为空时，该字段不会设置为空。在这种情况下，我如何检索所有非空数据。我试过这个：

$customers =  $this->Customer->find('list', 
                 array('fields' => array('email'),
                 'conditions' => array('event_id' => $this->request->data['Product']['event_id'],
                      'not' => array('Customer.email' => null) 
                  )
              )
          ); 

print_r($customers); 给出以下结果：

Array

当没有提供电子邮件值时，电子邮件字段不为空是合乎逻辑的，但我试图过滤这个空值，告诉它不是空值。有没有办法解决这个问题？

Answer 1

请添加条件，如

$customers =  $this->Customer->find('list', 
                 array('fields' => array('email'),
                 'conditions' => array('event_id' => $this->request->data['Product']['event_id'],
                      'AND' => array('not' => array('Customer.email' => null),'not' => array('Customer.email' => '') 
                  )
              )
          );
