嗨,我正在使用codeigniter框架.我已经完成了一个自动填充动作与onkey更改.我使用ajax来发布一个id值给我的控制器功能,将从服务表中获取单个数据行.
现在我有超过1个记录的排名是相同的id.例如,
现在我有超过1个记录的排名是相同的id.例如,
- +----+-----------------+------+
- + 1 + iPhone6 + 2 +
- +----+-----------------+------+
- + 1 + ipod + 5 +
- +----+-----------------+------+
这里我有两行具有相同的id现在当我发布id值,那么我需要获取数据和显示在我的视图页面.
为此,我需要在表中添加行.
我的控制器功能
- <?PHP
- class Admin_billing extends CI_Controller {
- public function __construct()
- {
- parent::__construct();
- $this->load->model('billing_model');
- }
- public function getdetails()
- {
- $data_to_search=$_POST['val'];
- $details=array();
- $details['description']=$this->billing_model->get_service_name($data_to_search);
- $details['type']=$this->billing_model->get_service_name($data_to_search);
- $details['price']=$this->billing_model->get_service_pricevalue($data_to_search);
- echo json_encode($details);
- }
- }
这里有一个getdetails()具有数组细节.在这个细节数组中,我有单个数据的键和值,例如它可以保存数据
description =>电话订单,type => iphone,price => $7000.这将填写我的视图页面中的数据.现在如果我有不止一行如何使它工作?
我的模型功能
- public function get_service_name($id)
- {
- $this->db->select('*');
- $this->db->from('service');
- $this->db->where('id',$id);
- $query = $this->db->get();
- $result = $query->result_array();
- return $result[0]['name'];
- }

这个我的视图页面在这里我有一个表与id测试,这个表由行与每个单元格中的输入元素.我有一个添加行按钮,调用一个javascript函数来动态添加行.在这个表中,我有一个输入元素与id =“pid []”当键更改操作发生时,它调用ajax函数并从数据库获取值.
这对单记录工作正常.当我有多个记录时,我没有明确的想法.
我需要得到一组数据.
2.动态添加行,并填充一个键更改操作中添加的所有行中的数据.
有人可以帮我代码吗?提前致谢.
解决方法
编辑:一旦获得了数组,只需要使用json_encode()并发回到ajax.在那里你可以解码它.你还需要在你的ajax中使用它:dataType:’json’
还要注意,我们在PHP和returnig $data数组中设置关键字’error’,如果有错误并检查ajax的success()中的值来推断是否有错误.
Javascript:注意这是你将要做的条纹化版本,但它的目的是为了你所需要做的.希望有帮助
- $.ajax ( { method : 'POST',url : scriptUrl,data : data,cache : false,processData: false,/** Don't process the data **/
- contentType: false,/** Set content type to false as jQuery will tell the server its a query string request **/
- dataType : 'json',/** we will return data in the key-value format from the PHP file **/
- success : function ( data,textStatus,jqXHR ) { /** We can treat the returned data as object. **/
- if ( typeof data.error === 'undefined' ) { /** damn error **/ }
- else { /** We got our data. **/
- for (var key in data) {
- alert(key + " -> " + data[key]);
- }
- }
- }
- $query = $this->db->get();
- /** Check for return value
- If there is an error,set error key,we will use it in the ajax to
- check if there was an error at the bancend
- */
- if ( ! $query ) { $data['error'] = TRUE; return $data; }
- /**
- * Array to hold our data.
- * For reference look at the foreach() loop.
- */
- $data = array ( );
- /** Get each record as $row. **/
- foreach ( $query->result ( ) as $row )
- {
- /**
- * Temporary array to hold the data of this record.
- */
- $temp = array ( );
- /** Get each value as $key => $value pair **/
- foreach ( $row as $key => $value)
- {
- $temp [ $key ] = $value;
- }
- array_push ( $data,$temp );
- }
- return $data;
现在$data是一个多维关联数组,$data [0]等于一个记录数组(‘id’=> 1,’name’=>’something’…);
- $data = array ( array ( 'id' =>1,'name' => 'something'... ),( 'id' =>1,.... );
