谁能解释为什么我不能将一个名为 $siteID 的变量传递给同一控制器中的另一个函数?
在名为“get_orders_by_site”的第三个函数中,我加载了一个不同的模型,它返回有关在当前查看的建筑物/站点/财产中提出的“订单”的信息。
站点控制器完美运行,第一个函数列出了一个包含我所有属性的表,然后单击一个函数 - 第二个函数获取该选择的站点 ID,并返回更多“详细信息/数据” - 站点控制器函数 1/2 都与相同的模型,并从 SAME 表返回信息。
我正在尝试实现第三个函数,它将执行类似的任务,但返回来自不同表的信息/数据(site.siteID,也是我在 phpmyadmin 中创建的 orders.siteID 表中的 FK) .
如果我需要进一步解释,请告诉我 - 非常感谢!
修改后的代码
站点控制器
<?php
class Sites extends CI_Controller {
//Searches for a list of sites
public function search($sort_by = 'site_title', $sort_order = 'asc', $offset = 0)
{
$limit = 20;
$data['columns'] = array(
'site_title' => 'Site Name',
'site_uprn' => 'Unique Property Reference'
);
$this->load->model('site_model');
$results = $this->site_model->get_sites($limit, $offset, $sort_by, $sort_order);
$data['sites'] = $results['rows'];
$data['num_results'] = $results['num_rows'];
//pagination for list returned
$this->load->library('pagination');
$config = array ();
$config['base_url'] = site_url("Sites/search/$sort_by/$sort_order");
$config['total_rows'] = $data['num_results'];
$config['per_page'] = $limit;
$config['uri_segment'] = 5;
$this->pagination->initialize($config);
$data['pagination'] = $this->pagination->create_links();
$data['sort_by'] = $sort_by;

// 这第二个函数应该执行与上面类似的方法,但是我加载了不同的模型,因为我从不同的数据库表中获取信息 - 但我仍然希望返回的数据受到建筑物/站点 ID 的限制用户选择的。

终端站点控制器
场地模型

订单模型
