php - 使用php在三个下拉选定值上上传文件

问题描述

我想从三个下拉菜单中上传特定选择的文件。

例如：
如果选择课程 (vfx)、教师 (john)、作业 (1)，则在提交文件时应将其上传到特定文件夹或位置。

谢谢你。

解决方案

首先你必须在你的表单周围创建表单元素，如果你已经创建了，那么我考虑它的方法是 POST 并且考虑到按钮名称是btn并且你的问题的代码如下：

<?php
        //Enter your code here, enjoy!

if(isset($_POST['btn']) )
{
    // getting the values from the form
    $courseValue = $_POST['Course'];
    $assignment = $_POST['assignment'];
    $faculty = $_POST['Faculty'];

    // condition to check for file uploading
    if($courseValue =="vfx" && $assignment == "1" && $faculty == "john")
    {
        // code to upload file or some other actions

    }
}
