我正在尝试创建一个需要输入的表单，例如。 3然后根据输入方式在循环中生成3个表单。有人可以看看这个，看看我的代码是否正确？目前我的表单验证由于某种原因立即失败，我不确定如何继续。
有成人表格和儿童表格。两者都取决于另一页的输入。
这是我的观点

我希望有人可以帮助我。我已经浏览了很长时间，我看不出我错过了什么，或者整个事情都错了。

我为您创建了一个简单的控制器和视图。
控制器：
public function test()
{
$view_data = array();
$view_data['step'] = 1; // default step
//step 1
if($this->input->post('_step') AND $this->input->post('_step')==1) {
$view_data['step'] = 1;
$this->form_validation->set_rules('children_length', 'How many children', 'trim|required|integer|min_length[1]');
$this->form_validation->set_rules('adult_length', 'How many adult', 'trim|required|integer|min_length[1]');
if($this->form_validation->run()) {
//set variable for status 2
$view_data['step'] = 2;
}
}
//step 2
if($this->input->post('_step') AND $this->input->post('_step')==2) {
$view_data['step'] = 2;
$children_length = (int)$this->input->post('children_length');
$adult_length = (int)$this->input->post('adult_length');
//validation for childrens
for($i=0;$i<$children_length;$i++) {
$this->form_validation->set_rules('childrens['.$i.'][firstname]', 'Children '.$i.' - firstname', 'trim|required');
$this->form_validation->set_rules('childrens['.$i.'][lastname]', 'Children '.$i.' - lastname', 'trim|required');
}
//validation for adults
for($i=0;$i<$children_length;$i++) {
$this->form_validation->set_rules('childrens['.$i.'][firstname]', 'Children '.$i.' - firstname', 'trim|required');
$this->form_validation->set_rules('childrens['.$i.'][lastname]', 'Children '.$i.' - lastname', 'trim|required');
}
if($this->form_validation->run()) {
//set variable for status 3
//here save etc
$view_data['step'] = 3;
}
}
$this->load->view('/test', $view_data);
}
查看：
<?php
if($step==3) {
//step 3 - show array from step 2
echo '<h3>Step 3</h3>';
echo '<pre>';
print_r($this->input->post());
echo '</pre>';
}elseif($step==2) {
//step 2 Generation form fo childrens and adults

echo form_open('', '', ['_step'=>2,'children_length'=>$this->input->post('children_length'),'adult_length'=>$this->input->post('adult_length')]);
echo '<div style="color:red">'.validation_errors().'</div>';
