Question

我已经编辑了以下代码，以便及时更新我所做的更改。我已设法将其保存但我仍然无法在重定向完成时显示“成功”消息。此外，如果出现错误错误，如何保存输入的数据？

控制器

class Addsale extends CI_Controller {

function __construct(){
parent::__construct();
}
function index() {
    if(!$this->session->userdata('logged_in')) {
        redirect('admin/home');
    }
    // set data
    $data['title'] = "Add Sale";
    $data['sales_pages'] = $this->sales_model->getSalesPages();
    $data['cms_pages'] = $this->navigation_model->getCMSPages();

    $this->load->library('form_validation');
    $this->form_validation->set_rules('name', 'Name', 'trim|required');
    $this->form_validation->set_rules('location', 'Location', 'trim|required');
    $this->form_validation->set_rules('bedrooms', 'Bedrooms', 'trim|is_natural|required');
    $this->form_validation->set_rules('bathrooms', 'Bathrooms', 'trim|required');
    $this->form_validation->set_rules('condition', 'Condition', 'trim|required');
    $this->form_validation->set_rules('description', 'Description', 'trim|required');
    $this->form_validation->set_rules('price', 'Price', 'trim|required');

    if($this->form_validation->run() === TRUE) {

    $data = array(  
        'name' => $this->input->post('name', TRUE),
        'location' => $this->input->post('location', TRUE),
        'bedrooms' => $this->input->post('bedrooms', TRUE),
        'bathrooms' => $this->input->post('bathrooms', TRUE),
        'condition' => $this->input->post('condition', TRUE),
        'description' => $this->input->post('description', TRUE),
        'price' => $this->input->post('price', TRUE)
        );

        $this->sales_model->addSale($data);

        redirect('admin/addsale' , $data);

        $this->session->set_flashdata('success', 'Page Saved');

    }else{
        $data['content'] = $this->load->view('admin/addsale', NULL, TRUE);
        $this->load->view('template', $data);
        }

}


    }

查看

<?php
//Setting form attributes
$formAddSale = array('id' => 'addSale', 'name' => 'addSale');
$saleName = array('id' => 'name', 'name' => 'name'); 
$saleLocation = array('id' => 'location', 'name' => 'location');

?>

<section id = "validation"><?php print $this->session->flashdata('success');?> </section>
<section id = "validation"><?php echo validation_errors();?></section>

<?php
echo form_open('admin/addsale/', $formAddSale);

模型

function addSale($data) {

$this->db->insert('sales', $data);
return;
}

Answer 1

您是否正在使用set_message来显示“已完成”的消息？如果是这样，那么就不会显示，因为你正在进行重定向。

尝试在重定向之前在flashdata中设置一条消息，如下所示：

$这 - ＆GT;会话而＆GT; set_flashdata（ '成功'， '页面已保存'）;

然后在您的视图中将其打印出来：

打印$ this-＆gt; session-＆gt; flashdata（'success'）

Answer 2

在我看来，这行中有太多“=”：

 if($this->form_validation->run() === TRUE) {

如果数据没有运行Form_validation
