Question

完成

是否有机会在控制器操作中两次使用$ this-＆gt; form_validation-＆gt; run（）？ CodeIgniter似乎只验证了第一条规则。我想使用$ this-＆gt; form_validation-＆gt; run（）两次，因为我需要第二个验证规则的验证值;）。

$this->form_validation->set_rules(...);
if($this->form_validation->run() === true)
{
    $value = $this->..._model->get( ...);  //use of validated value
    $this->form_validation->set_rules(...); //use of $value
    if($this->form_validation->run() === true)
    {
        //...
    }
}

尝试在加载时为form_validation库分配别名？这可能会解决问题。

$this->load->library('form_validation','','validation1');
$this->validation1->set_rules(...);
if($this->validation1->run() === true)
{
    $value = $this->..._model->get( ...);  //use of validated value
    $this->load->library('form_validation','','validation2');
    $this->validation2->set_rules(...); //use of $value
    if($this->validation2->run() === true)
    {
        //...
    }
}

Answer 2

在核心文件中 - CodeIgniter_2.1.3 / system / libraries / Form_validation.php 添加一行

$this->_field_data = array();

方法run（）;

中的

public function run($group = '')
    {
        // add this line for clear field data to use validation many times
        $this->_field_data = array();

PHP：CodeIgniter $ this-＆gt; form_validation-＆gt; run（）验证两次？
