Question

我对客户有非常关键的要求。他想上传多项选择题。要上传的问题可以是文本内容，也可以是图像。所以有一个输入字段用于问题，可以是文本或图像，与问题i的其他4个选项相同。即文字或图像。意味着他可以输入问题，也可以只是同时上传图像文件;同一问题的答案是可以是文本或图像的选项。这是一个非常关键的问题，多文件上传文本数据。我在核心php中编程相同，它工作正常。我使用base64编码实现了这一点。但我想要CodeIgniter格式的相同代码。那是MVC架构格式。这是我在核心php中的代码。

<?php
$message = "Enter question ";

$this->load->database();
if (isset($_POST['no']) ){


$target_path = "./uploadIMG/";

if(move_uploaded_file($_FILES['que']['tmp_name'], $target_path)) {


   // echo "The file ".  basename( $_FILES['que']['name']). 
   // $img_file = $target_path.$_FILES["que"]["name"];
$imgData = base64_encode(file_get_contents($target_path));
//$src = 'data: '.mime_content_type($img_file).';base64,'.$imgData;
$que = $imgData;    

$a = "0";

我想在MVC codeigniter中转换我的代码
