在 codeigniter 中的 jQuery POST 之后返回 json 编码响应的问题

我在使用 jQuery post 后收到响应时遇到问题。我正在创建的脚本正确发布数据并正确插入到数据库中，但是当我尝试返回 json 编码响应时，没有收到数据。

这是我正在使用的代码：

jQuery.ajax({
     success: function(data) {
            if (data)
            {
            alert("DATA RECEIVED");
            }
            },
          data: {action: 'create', section: JSON.stringify(values)},
          type: 'POST',
          dataType: 'json',
            url: "fields/sections/create" 
        });

在我的控制器中

$section = json_decode($this->input->post('section'));


            $this->load->model('mdl_fields');


            $section_id = $this->mdl_fields->create_section($section->name, $section->row);

            if($section_id) {

                $data=array(
"section" => $section_id,
"confirm" => 'Section Has Been Created Successfully'
);
return json_encode($data);
}

，我已经检查了是否有 $section_id ，并且我已经打印了 json_encode($data) 以检查它是否正确，确实如此，但我仍然没有收到响应。

在过去的几个小时里，我一直在努力解决这个问题，所以任何帮助将不胜感激。

谢谢

I am having problems receiving response after using jQuery post. The script I am creating posts the data correctly and inserts correctly to the database however when I try and return a json encoded response no data is received.

Here is the code I am using:

jQuery.ajax({
     success: function(data) {
            if (data)
            {
            alert("DATA RECEIVED");
            }
            },
          data: {action: 'create', section: JSON.stringify(values)},
          type: 'POST',
          dataType: 'json',
            url: "fields/sections/create" 
        });

In my controller I have

$section = json_decode($this->input->post('section'));


            $this->load->model('mdl_fields');


            $section_id = $this->mdl_fields->create_section($section->name, $section->row);

            if($section_id) {

                $data=array(
"section" => $section_id,
"confirm" => 'Section Has Been Created Successfully'
);
return json_encode($data);
}

I have checked there is a $section_id and I have printed json_encode($data) to check it is correct, which it is, but I am still not receiving a response.

I have been tearing my hair out trying to solve this for the last few hours so any help would be appreciated.

Thanks

也许您只需要制作类似的东西

echo json_encode($data);

，即可生成 JSON 兼容格式的 $data 结构的纯输出。看看 json_encode 它返回字符串并且不产生任何输出！

Maybe you simply need to make something like

echo json_encode($data);

that would generate plain output of $data structure in JSON compatible format. Take a look at json_encode it return string and does NOT produce any output!
