PHP 图像上传器 - IE“pjpeg” MIME 类型，不起作用
我在使用图像上传脚本时遇到困难，难以在 Internet Explorer 中上传图像。我一直在 Google 中搜索解决方案，添加“image/pjpeg”mime 类型似乎对每个人都有效，但我已将其添加到我的代码中，但仍然无法使其工作。
这就是我的情况：
$acceptedExts = array ('jpg','jpeg');
if ( in_array($ext,$acceptedExts)
&& ( $_FILES["uploaded_file"]["type"] == "image/pjpeg"
|| $_FILES["uploaded_file"]["type"] == "image/jpeg")
&& ($_FILES["uploaded_file"]["size"] < 16000000)) {
我做错了什么吗？
谢谢！
I am having a hard time with my image upload script, getting the images to upload in Internet Explorer. I have been searching Google for a solution and adding the "image/pjpeg" mime type seemed to work for everyone, but I have added it to my code and still cannot get it to work.
Here is what I have:
$acceptedExts = array ('jpg','jpeg');
if ( in_array($ext,$acceptedExts)
&& ( $_FILES["uploaded_file"]["type"] == "image/pjpeg"
|| $_FILES["uploaded_file"]["type"] == "image/jpeg")
&& ($_FILES["uploaded_file"]["size"] < 16000000)) {
Am I doing anything wrong?
Thanks!

尝试使用
var_dump($_FILES['uploaded_file'])来准确查看 IE 发送的内容。它可能是image/jpg或完全不同的东西。但是，使用用户提供的['type']字段进行验证是一种不好的形式。塑造这个价值是微不足道的。最好使用服务器端方法来确定文件类型，例如get_image_size()或FileInfo库，两者都返回文件的真实 mime 类型。Try a
var_dump($_FILES['uploaded_file'])to see exactly what IE's sending. It may beimage/jpgor something completely different. However, it's bad form to use the user-provided['type']field for validation. It's trivial to forge that value. Better use a server-side method to figure out file type, such asget_image_size()or theFileInfolibrary, both of which return the true mime-type of the file.
