Question

我有这个HTML代码，用于将文件发布到我的上传脚本：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<head>
    <title>CONTISEC PORTAL - NEW USER</title>

    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <link rel="stylesheet" href="buttcss/gstyle_buttons.css" type="text/css"  media="screen">
    <link rel="stylesheet" type="text/css" href="usercon.css" />
</head>

<body>

    <div id="page-wrap">



        <p>CREATE NEW CLIENT USER ACCOUNT BY ENTERTING CLIENT REFERENCE NUMBER (supplied by Pershing) AND DESIRED USERNAME.</p>





        <div id="contact-area">

            <form method="post" action="fileproc.php">
                <enctype="multipart/form-data">
                <label for="client_ref">BROWSE:</label>
                <input type="file" name="file" id="file" />
                <label for="client_ref">SELECT FILE:</label>
                <select name="file"> 
                <option value="assets" >ASSETS (DAILY)</option>
                <option value="stock_names" >STOCK_NAMES (DAILY)</option>
                <option value="client_names" >CLIENT_NAMES</option>
                </select>

                <div class="buttons">

                <button class="action redbtn" type="submit"><span class="label">SUBMIT</span></button>
            </form>

            <div style="clear: both;"></div>



        </div>

    </div>

</body>

</html>

这是我的上传脚本（来自w3学校）：

<?php


if ($_FILES["file"]["error"] > 0)
  {
  echo "Error: " . $_FILES["file"]["error"] . "<br>";
  }
else
  {
  echo "Upload: " . $_FILES["file"]["name"] . "<br>";
  echo "Type: " . $_FILES["file"]["type"] . "<br>";
  echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
  echo "Stored in: " . $_FILES["file"]["tmp_name"];
  }




?>

但是，当页面加载时，它会显示“未定义的索引”错误。有人知道为什么会这样吗？

Answer 1

将以下内容添加到表单打开标记中。它是上传文件所必需的

enctype="multipart/form-data"

Answer 2

Sam您对文件选择字段和选择字段具有相同的名称，这必须导致问题。 <input type="file" name="file" id="file" />

<select name="file">

文件上载脚本不起作用
