javascript - Codeigniter - JSON 类别
问题描述
我想用 JSON 显示包类别。我有 2 张桌子。第一个是Package Table，第二个是packageService。第一个表是包表。我从包表中获取所有数据。每个包都有自己的功能（服务）。我在包视图中显示此功能包。我想从 packageServices 获取所有功能（服务）。但是我想通过 packageServiceId 从带有 JSON 的 packageService 表中获取此功能，例如 [1][2] 等。在 Package Table 中有一个列作为 packageService，在 packageService 表上等于 packageServiceId。如何使用 JSON 将编辑页面上的帖子表单中的数据写入打包表？

解决方案
在 codeingitor 中，您可以像这个例子一样以 JSON 的形式获取表格数据
在模型中
function function_table_name(){
$query = $this->db->get('table_name');
return $query->result();
}
在控制器中
public function employees()
{
$data = array();
$data = $this->model_name->function_table_name();
echo json_encode($data);
// echo '<pre>';
// print_r($data);
}
如果你想在视图中加载它，你可以这样做。
控制器.php
$data = array();
$data['myJson'] = json_decode(file_get_contents('some_url'));
$this->load->view('my_view',$data);
视图.php
<?php
//Access them like so
print_r($myJson);
// Rest of your code here to play with json
?>
</html>
