我应该将php json编码转换为Ajax数组，第一次对我来说很难理解 - I should convert php json encode to Ajax array, the first time for me enough difficult to understand

I should convert php json encode to Ajax array, the first time for me enough difficult to understand

Controller

public function api_students()
{
    $students = $this->member->getStudentsPosts();
    $new_students = array();
    for($i=0; $i<count($students); $i++) 
    {
        $new_students[$i]['student_fullname'] = $students[$i]->student_name.' '.$students[$i]->student_surname.' '.$students[$i]->student_middlename;
        $new_students[$i]['student_id']       = $students[$i]->student_id;
        $new_students[$i]['student_birth']    = $students[$i]->student_birth;
        $new_students[$i]['student_gender']   = $students[$i]->student_gender;
        $new_students[$i]['student_addres']   = $students[$i]->student_addres;
        $new_students[$i]['student_mobile']   = $students[$i]->student_mobile;
        $new_students[$i]['student_email']    = $students[$i]->student_email;
    }
    $this->output
            ->set_content_type('application/json')
            ->set_output(json_encode($new_students));
}

阿贾克斯

$('.students').click(function(){
    var student_id = $(this).attr('data-student-id');
    $.get(site_url+'/members/api_students/'+ student_id,
        function(new_students){
            $('#student_name').text(new_students.student_name);
        },'json'
    );})

问题是，我想从api_students获取信息并通过ajax查看。控制台没有显示任何错误消息，它是空的，所以我不知道要检查什么。我检查了api_students，数据来了，我的ajax代码中有问题

您可以使用

控制器

// get id and send array
public function api_students()
{
    $students = $_POST['id'];
  /// code 
    echo json_encode($new_students);
}

阿贾克斯

// send data and use the result
$.ajax({
       type: "POST", 
       url: site_url+'/members/api_students/'+ student_id,    
       data:  'id='+student_id;
       success: function(stud){ 
           // use result array stud
       }
});

不是一个完整的答案，但不能把它放在评论中。

据我所知，您的PHP块旨在发送许多学生的详细信息，而不仅仅是一个。如果您在 API 调用中发送student_id，那么您的 PHP 代码肯定应该只为单个学生发送一个 JSON 对象，而不是他们的数组。

如果要发送数组，请更快、更轻松地进行 JSON 块准备...

$new_students = array();
foreach ($students as $s) {
    // pre PHP 5.4 use array( instead of [...
    $new_students[] = [
        'student_fullname' => $s->student_name . ' ' . $s->student_surname . ' '.$s->student_middlename,
        'student_id' => $s->student_id,
        'student_birth' => $s->student_birth,
        'student_gender' => $s->student_gender,
        'student_addres' => $s->student_addres,
        'student_mobile' => $s->student_mobile,
        'student_email' => $s->student_email,
    ]
}
