推荐答案

尝试一下。它是通过使用CI验证库。
它使用回调类型的验证。

Try this. It is by using CI validation library. It uses callback type of validation.

将此内容放入 if（isset（$ _ POST ['submit_button_name']））{} 部分。
首先，加载验证数组，

Put this in if(isset($_POST['submit_button_name'])) {} section. First, load validation array,

$validation = array(
  array('field' => 'startDate', 'label' => 'StartDate', 'rules' => 'required|callback_compareDate'),
  array('field' => 'endDate', 'label' => 'endDate', 'rules' => 'required|callback_compareDate'),
);

然后将CI验证库加载为，

Then load CI validation library as,

$this->form_validation->set_rules($validation);
$this->form_validation->set_message('required', '%s is required.');

这是回调函数。

function compareDate() {
  $startDate = strtotime($_POST['startDate']);
  $endDate = strtotime($_POST['endDate']);

  if ($endDate >= $startDate)
    return True;
  else {
    $this->form_validation->set_message('compareDate', '%s should be greater than Contract Start Date.');
    return False;
  }
}

必填验证使字段必填充满了东西。
在这种情况下，回调函数比较日期，如果开始日期小于起始日期，则进一步处理表单，否则标记错误。

The "required" validation makes the fields mandatory to be filled with something. The callback function, in this case, compares the dates, and further processes the form if start date is less than from date OR flags error otherwise.
