Question

我正在尝试将文件上传到服务器上。每当我提交时，php全局数组$ _FILES都是空的。我的文件继续进入$ _POST。

        <form action="process.php" method="POST">
            <div class="form-group"></div>
            <div class="form-group">
                <input type="file" name="uploaded_file">
            </div>
            <div class="form-group">
                <button type="submit" class="btn btn-danger">Upload</button>
            </div>
        </form>

process.php

<?php
var_dump($_FILES['uploaded_file']);
var_dump($_POST['uploaded_file']);

Answer 1

你应该像这样使用enctype="multipart/form-data"

<form action="process.php" method="POST" enctype="multipart/form-data">
            <div class="form-group"></div>
            <div class="form-group">
                <input type="file" name="uploaded_file">
            </div>
            <div class="form-group">
                <button type="submit" class="btn btn-danger">Upload</button>
            </div>
</form>

Answer 2

将enctype="multipart/form-data"添加到html中像：

<!DOCTYPE html>
 <html>
 <body>

<form action="upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>

文件上传进入POST而不是FILE
