标签： php html base64 image-upload

我正在尝试创建一个表单，用户可以通过网站联系表单上传自己的图像...但是，我可以收到输入的措辞但不是附件......有人可以指出错误吗？

$max_allowed_file_size = 10000; // size in KB
$allowed_extensions = array("jpg", "jpeg", "gif", "bmp");
$upload_folder = './uploads/'; //<-- this folder must be writeable by the script
$your_email = 'tcc@hotmail.com';//<<--  update this to your email address

$errors ='';

if(isset($_POST['submit']))
{
  //Get the uploaded file information
  $name_of_uploaded_file =  basename($_FILES['uploaded_file']['name']);

  //get the file extension of the file
  $type_of_uploaded_file = substr($name_of_uploaded_file, 
                          strrpos($name_of_uploaded_file, '.') + 1);

  $size_of_uploaded_file = $_FILES["uploaded_file"]["size"]/1024;

将表单中的enctype属性设置为＆＃34; multipart / form-data＆＃34;否则，文件字段不起作用。

答案 1 :(得分：0)

在表单中，您需要添加enctype="multipart/form-data"

所以即：

<form method="POST" name="email_form_with_php" 
enctype="multipart/form-data"
onsubmit="return validateForm()"
