问题描述

我正在尝试创建一个接受输入的表单。 3，然后根据输入方式在循环中生成3种形式。 有人可以浏览一下，看看我的代码是否正确？ 目前，由于某种原因，我的表单验证立即失败，我不确定如何进行。

有成人形式和儿童形式。 两者都取决于另一页的输入。

这是我的看法 

<?php echo form_open_multipart('Public/Details/next','class="inputform"');?>
                    <h3>Adults</h3>
                    <?php for($i=0;$i<$adults;$i++){?>

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);
    }

视图： 

<?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($step==2) {
    //step 2 Generation form fo childrens and adults
    echo '<h3>Step 2</h3>';
    echo form_open('', '', ['_step'=>2,'children_length'=>$this->input->post('children_length'),'adult_length'=>$this->input->post('adult_length')]);
        echo '<div style="color:red">'.validation_errors().'</div>';

        echo '<h4>Childrens</h4>';
        for($i=0;$i<$this->input->post('children_length');$i++) {
            echo form_input(['type'=>'text','name'=>'childrens['.$i.'][firstname]','value'=>set_value('childrens['.$i.'][firstname]'),'placeholder'=>'Children '.$i.' - firstname']);
            echo form_input(['type'=>'text','name'=>'childrens['.$i.'][lastname]','value'=>set_value('childrens['.$i.'][lastname]'),'placeholder'=>'Children '.$i.' - lastname']);
            echo '<br><br>';
        }

        echo '<h4>Adults</h4>';
        for($i=0;$i<$this->input->post('adult_length');$i++) {
            echo form_input(['type'=>'text','name'=>'adults['.$i.'][firstname]','value'=>set_value('adults['.$i.'][firstname]'),'placeholder'=>'Adult '.$i.' - firstname']);
            echo form_input(['type'=>'text','name'=>'adults['.$i.'][lastname]','value'=>set_value('adults['.$i.'][lastname]'),'placeholder'=>'Adult '.$i.' - lastname']);
            echo '<br><br>';
        }
        echo form_input(['type'=>'submit','value'=>'Next (go to step 3)']);
    echo form_close();
}else {
    //step 1 How many children as adults
    echo '<h3>Step 1</h3>';
    echo form_open('', '', ['_step'=>1]);
        echo '<div style="color:red">'.validation_errors().'</div>';
        echo form_input(['type'=>'text','name'=>'children_length','value'=>set_value('children_length'),'placeholder'=>'How many children']);
        echo form_input(['type'=>'text','name'=>'adult_length','value'=>set_value('adult_length'),'placeholder'=>'How many adult']);
        echo form_input(['type'=>'submit','value'=>'Next (go to step 2)']);
    echo form_close();
}
?>
