Question

我使用Codeigniter RESTful API根据输入从数据库中获取数据。现在我想以不同的方式改变显示我的json输出的方式。

CODE：

function categoryskills_get()
{
    $category = $this->get('category');
    $skills = $this->Users_model->categoryskills($category);
    if($skills != FALSE)
    {
        $sub_cat = 0;
        foreach($skills['skills'] as $row)
        {
            $data[$skills['cat']][]['sub_category'] = $row['sub_cat'];
            $data[$skills['cat']][]['skills'] = $row['s_name'];
        }
        $this->set_response($data, REST_Controller::HTTP_OK);
    }else{
        $response["error"] = TRUE;
        $response["status"] = '404';
        $response["error_msg"] = "Category not found!";
        $this->set_response($response, REST_Controller::HTTP_NOT_FOUND);
    }
}

上面的代码是我的http请求的控制器。

当前输出：

{
"Consultants": [
    {
        "sub_category": "Consultants"
    },
    {
        "skills": "Career Counsellor, Creative Consultant,Digital Consultant"
    },
    {
        "sub_category": "Accounting"
    },
    {
        "skills": "Accountant,Auditor,Tax Specialist"
    }

 ]
}

预期输出：

{
"Consultants": [
    {
        "sub_category": "Consultants",
        "skills": "Career Counsellor,Creative Consultant,Digital Consultant"
    },
    {
     .....
    }
 ]
}

Answer 1

function categoryskills_get()
{
    $category = $this->get('category');
    $skills = $this->Users_model->categoryskills($category);
    if($skills != FALSE)
    {
        $sub_cat = 0;
        foreach($skills['skills'] as $key=>$row)
        {
            $data[$skills['cat']][$key]['sub_category'] = $row['sub_cat'];
            $data[$skills['cat']][$key]['skills'] = $row['s_name'];
        }
        $this->set_response($data, REST_Controller::HTTP_OK);
    }else{
        $response["error"] = TRUE;
        $response["status"] = '404';
        $response["error_msg"] = "Category not found!";
        $this->set_response($response, REST_Controller::HTTP_NOT_FOUND);
    }
}

使用foreach作为键，值并将$ key放入数组中$data[$skills['cat']][$key]['sub_category'] 你会得到理想的输出

Answer 2

为sub_cat和技能

创建单独的临时数组

$category = $this->get('category');
    $skills = $this->Users_model->categoryskills($category);
    $data = array();//create an empty array
    if($skills != FALSE)
    {
        $sub_cat = 0;
        foreach($skills['skills'] as $row)
        {
            $arr['sub_category'] = $row['sub_cat'];
            $arr['skills'] = $row['s_name'];//makes an $arr array

            $data[$skills['cat']][] = $arr;  //and after that add it to                        main array
        }
        $this->set_response($data, REST_Controller::HTTP_OK);
    }else{
        $response["error"] = TRUE;
        $response["status"] = '404';
        $response["error_msg"] = "Category not found!";
        $this->set_response($response, REST_Controller::HTTP_NOT_FOUND);
    }
}

function categoryskills_get()
{
    $category = $this->get('category');
    $skills = $this->Users_model->categoryskills($category);
    if($skills != FALSE)
    {
        $sub_cat = 0;
        foreach($skills['skills'] as $row)
        {
            $data[$skills['cat']][] = array('sub_category'=>$row['sub_cat'],'skills'=>$row['s_name']);
        }
        $this->set_response($data, REST_Controller::HTTP_OK);
    }else{
        $response["error"] = TRUE;
        $response["status"] = '404';
        $response["error_msg"] = "Category not found!";
        $this->set_response($response, REST_Controller::HTTP_NOT_FOUND);
    }
}

Answer 4

使用如下所示的array_push()方法：

$category = $this->get('category');
    $skills = $this->Users_model->categoryskills($category);
    $data = array();//create an empty array
    if($skills != FALSE)
    {
        $sub_cat = 0;
        foreach($skills['skills'] as $row)
        {
            $arr['sub_category'] = $row['sub_cat'];
            $arr['skills'] = $row['s_name'];//makes an $arr array
            array_push($data[$skills['cat']], $arr);//push array
        }
        $this->set_response($data, REST_Controller::HTTP_OK);
    }else{
        $response["error"] = TRUE;
        $response["status"] = '404';
        $response["error_msg"] = "Category not found!";
        $this->set_response($response, REST_Controller::HTTP_NOT_FOUND);
    }
}
