我有一个视图，其中我使用带有单选按钮的表单来显示公司中的所有员工。 （我使用一个简单的java脚本，允许在不使用提交按钮的情况下提交表单，并通过单选按钮将员工ID传递给控制器）
<script language="JavaScript" type="text/javascript"><!--
function submit ()
{
document.select_employee.submit() ;
}
--></script>
<title>Employee Master</title>
<a href="<?php echo (base_url('index.php/employee_master/add_employee'))?>">Add New Employee </a>
<a href="javascript:submit()">Edit Employee</a>
<a href="">Delete Employee </a>
<br />
<?php $id_people = "0"; ?>
<form name ="select_employee" id="select_employee" action="<?php echo (base_url('index.php/employee_master/edit_employee/'.$id_people.''))?>" method="post">
<br />
<?php foreach($rows as $person) { ?>
<?php $id_people=$person['id_people']; ?>
<input type = "radio" class='rad_button' name = "employee_id" value="<?php echo $id_people ; ?>"/>
<?php
foreach($person as $object){
echo $object; ?>_______
<?php } ?> <br>
<?php } ?>
</form>
</body>
</html>
<script>
$(".rad_button").click(function() {
$("#select_employee").attr('action', "<?php echo base_url('index.php/employee_master/edit_employee')?>" + "/" + $(this).attr('value'));
console.log($("#select_employee").attr('action'));
})
</script>
之前，我从post发送了$ id_people但是我添加了通过url传递它的脚本。这是传递给它的控制器。
public function edit_employee($id_people){
if(empty($id_people)){
$this->session->set_flashdata('message', "please select an employee");
redirect(base_url('index.php/employee_master'), 'refresh');
} else {
$this->load->model('employee_master_model');
$info=$this->employee_master_model->get_info($id_people);//this will query the db every time form validation fails, may need to streamline
$this->load->library('form_validation');
$this->load->config('form_validation');
if ($this->form_validation->run('employee_master/edit_employee') == FALSE)
{
$this->load->view("forms/edit_employee", $info);
}
else
{ . . . (unrelated part of the controller)...
当这个控制器第一次加载forms_ edit_employee时，每个错误都填充了validation_errors（）！这是我的配置文件，我从
调用验证规则<?php //contains validation rules for all forms in application. name of array corrisponds to controller name and function name

如果我理解正确，请将表单验证包装到：
if($this->input->post('submit_button_name_or_input_name'))
{
// run validation
}
现在正在进行的是您的验证运行，第二次显示您的表单。

将验证分配给变量
＆＃39; $ data [＆＃39; form2_errors＆＃39;] = validation_errors（）;＆＃39;
