php - 使用 codeigniter 在表单上显示每个数据

Question

我是 CodeIgniter 的新手，正在探索它。我很难做到这一点。到目前为止，这是我尝试过的。

Controller.php

    <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Customer_controller extends CI_Controller{
    public function __construct()
    {
        parent::__construct();
        $this->load->model('customer_model');
    }
    public function index()
    {
        $data['title']= 'Customer';
        $data['records'] = $this->customer_model->getAll();
        $data['groups'] = $this->customer_model->getAllCustomerGroups();
        $data['groupcodes'] = $this->customer_model->getAllCustomerGroups();
        $this->load->view('include/header',$data);
        $this->load->view('include/navbar',$data);
        $this->load->view('customer_view', $data);
        $this->load->view('include/sidebar',$data);
        $this->load->view('include/footer',$data);

    }
}

模型.php

 function getAll() {
            $query = $this->db->get('customercard');
            return $query->row_array();       
        }

View.php

              <form class="form-horizontal" role="form">
          <div class="form-group">
            <label for="inputCustomerCode3" class="col-sm-2 control-label">Code</label>
            <div class="col-sm-4">

        </form>

我想做的是将数据库中的数据显示到我的表单中。我选择了

  $query = $this->db->get('customercard');

产生

  SELECT * FROM customercard

但我想在表单上显示每条记录，然后如您所见，我有导航按钮，第一个、上一个、下一个和最后一个。我想使用这些按钮循环播放记录。我不知道如何在 View 中显示它。所以我要求你给我一些入门教程或帮助我编写代码，以便我可以继续我正在做的事情。非常感谢您的帮助。提前谢谢大家!

Answer 1

将模型更改为

function getAll() {
            $query = $this->db->get('customercard');
            return $query->result_array();       
        }

另请注意，当您将 $data['records'] 传递给 View 时，您只需从 View 中通过 $records 即可访问它。

在您看来，只需循环遍历即可。

<?php
foreach ($recordsas $value)
  {
  echo "$value <br>";
  }
?>

------------您可以尝试以下操作。这是一种根据您的需要获取下一条记录的简单方法。

型号

public function fetch_customers($limit, $start) {
    $this->db->select('customercode,customername,customergroup,customertype,customeraddress,website');
    $this->db->limit($limit);
    $this->db->where('customercode >',$start);
    $this->db->order_by('customercode');
    $query = $this->db->get('customercard');
    if ($query->num_rows() > 0) {
        $row = $query->row();
        $data[] = $row;
        return $data;
    } else {
        return false;
     }
}

Controller

public function index(){
    $shown_id = 0;
    if(isset($this->uri->segment(3)){
        $shown_id = $this->uri->segment(3);
    }
    $this->load->model('customers_model');
    $data['info'] = $this->customers_model->fetch_customers(1,$shown_id);
    $this->load->view('customer_info',$data);
}

查看

$customer_id = $info->customercode;
$customer_name = $info->customername;
//Use like above to get the customer info and show as you like

但是，当您制作“下一步”按钮时，您需要将 $customer_id 传递回 Controller 。您也可以让超链接执行此操作。

<a href="<?php echo base_url();?>controller_name/index/<?php echo $customer_id;?>"

或者使用带有 onclick 和 window.location 的按钮
