Question

如何检查是否验证了第一条规则，然后无需检查第二/第三条规则，例如：

$this->form_validation->set_rules('children','Do you have children?','required');// e.g : answer no!

$this->form_validation->set_rules('son','How many sons?','required');//second rule
$this->form_validation->set_rules('daughter','How many daughter?','required');//third rule

Answer 1

简单的只是放置第一条规则并在IF

中进行表单验证

$this->form_validation->set_rules('children','Do you have children?','required'); 
if ($this->form_validation->run() == FALSE)    
{
$this->form_validation->set_rules('son','How many sons?','required');//second rule
$this->form_validation->set_rules('daughter','How many daughter?','required');//third rule
}

如果第一条规则失败则会检查第二条和第三条规则，否则如果第一条规则得到验证，则不会检查第二条和第三条规则

希望它有意义

Answer 2

您可以使用codeignitor中的回调函数或在CI核心验证库中添加您自己的规则来实现此目的这是我们如何使用回调函数 CI CallBacks

这就是我们如何拥有自己的自定义验证功能 Custom validation

Answer 3

您可以使用form_validation，如下所示

if ($this->form_validation->required($key)){
       //validation did not pass      
}

其中$key为$_POST['children']或$this->input->post('children');

TRUE / FALSE表是here

Codeigniter：如果第一条规则得到验证，则无需检查下一条规则
