Question

使用我目前的代码，我可以使用json_encode从dbase中获取正确的详细信息。

 [{
    "tour_id": "1",
    "tour_name": "Test this",
    "start": "2016-01-12 13:21:32",
    "end": "2016-01-15 13:21:35",
    "itinerary_photo": "Desert.jpg"
 }][{
    "tour_id": "3",
    "tour_name": "Everest",
    "start": "2016-02-10 13:23:00",
    "end": "2016-02-18 13:23:07",
    "itinerary_photo": "Chrysanthemum.jpg"
}]

预期JSON FEED
我正在使用json feed以向fullcalendar添加事件。我的json_encode结果的格式应该是这样的：

[{
    "tour_id": "1",
    "tour_name": "Test this",
    "start": "2016-01-12 13:21:32",
    "end": "2016-01-15 13:21:35",
    "itinerary_photo": "Desert.jpg"
}, {
    "tour_id": "3",
    "tour_name": "Everest",
    "start": "2016-02-10 13:23:00",
    "end": "2016-02-18 13:23:07",
    "itinerary_photo": "Chrysanthemum.jpg"
}]

区别在于对象仅存储在一个数组中。随着输出的增加，它会显示多个数组。

这是我的控制器代码：

public function getBookedCal(){
    if ($this->session->userdata('login')==true){
        $data['twimembers'] = $this->session->userdata('twimembers');
        $data['tour'] = $this->Model_MyBookedTours->getPaidTours($data['twimembers']['user_id']);
        foreach ($data['tour'] as $tourConfirm){
            $tourConfirm = $this->Model_MyBookedTours->getTourInfo($tourConfirm['Tour_packages_tourpkg_id']);
            echo json_encode($tourConfirm);
        }   
        //echo json_encode($tourConfirm); //this outputs only a single array
    }//end if
}//end function

MODEL：

function getPaidTours($user_id){
    $this->db->where('User_accounts_user_id',$user_id);
    $this->db->where('payment_status','1'); //confirmed
    $query = $this->db->get('user_tourpkg');
    return $query->result_array();
} //calendar

function getTourInfo($tour_id){
    $this->db->select('tour_id,tour_name, start, end, itinerary_photo');
    $this->db->where('tour_id',$tour_id);
    $query = $this->db->get('tour_packages');
    return $query->result();
}

有什么方法可以通过对我的代码进行一些调整来获得我期望的json Feed吗？

Answer 1

不要使用变量使用数组，也不要使用foreach值作为赋值

Answer 2

你必须在每个循环之前将$tourConfirm声明为数组，并在循环之后将该数组编码为json。
例如

public function getBookedCal(){
if ($this->session->userdata('login')==true){      $tmptourConfirm = array(); $data['twimembers'] = $this->session->userdata('twimembers');
    $data['tour'] = $this->Model_MyBookedTours->getPaidTours($data['twimembers']['user_id']);
    foreach ($data['tour'] as $tourConfirm){
        $tourConfirm[] = $this->Model_MyBookedTours->getTourInfo($tourConfirm['Tour_packages_tourpkg_id']);

    }   
    echo json_encode($tourConfirm);
}//end if

} /

Answer 3

按如下方式更改getBookedCal()，

public function getBookedCal(){
    $tourConfirm = array();  
    if ($this->session->userdata('login')==true){
        $data['twimembers'] = $this->session->userdata('twimembers');
        $data['tour'] = $this->Model_MyBookedTours->getPaidTours($data['twimembers']['user_id']);
        foreach ($data['tour'] as $tourConfirm){
            $tourConfirm[] = $this->Model_MyBookedTours->getTourInfo($tourConfirm['Tour_packages_tourpkg_id']);

        }   
        //echo json_encode($tourConfirm); //this outputs only a single array
    }//end if
    echo json_encode($tourConfirm);
}//end function

codeigniter中的json_encode格式
