Can not upload file, please help.

[Lauj]

Why is this not working?

if(!preg_match('#^(gif|jpg|jpe?g|png)$#i',$type)){
      unlink($HTTP_POST_FILES['userfile']['tmp_name']);
      die('file was wrong image-type');
    }

I kept getting the file was wrong image-type. I tried to upload a .jpeg file.

By the way, can anyone point me to an explanation on the use of this ^, $ or (?<=x).

Here is the full code.

<?php
$uploaddir = '/www/home/alumni/images/gallery/';
$uploadfile = $uploaddir . $HTTP_POST_FILES['userfile']['name'];
$fileName = $HTTP_POST_FILES['userfile']['name'];

if(!is_uploaded_file($HTTP_POST_FILES['userfile']['tmp_name'])){
	die('Hacking Attempt!');
	}
list($width, $height, $type, $size) = getimagesize($HTTP_POST_FILES['userfile']['tmp_name']);
echo "Size: ".$size."<br>";
if($size == false){
  	unlink($HTTP_POST_FILES['userfile']['tmp_name']);
  	die('file wasn\'t an image');
	}
echo "Explode: ".explode('/',$size['type']);
list(,$type) = explode('/',$size['type']);

if(!preg_match('#^(gif|jpg|jpe?g|png)$#i',$type)){
  	unlink($HTTP_POST_FILES['userfile']['tmp_name']);
  	die('file was wrong image-type');
	}
if (move_uploaded_file($HTTP_POST_FILES['userfile']['tmp_name'], $uploadfile)) {
   	print "File is valid, and was successfully uploaded.<br>";
	list($width, $height, $type, $attr) = getimagesize("/www/home/alumni/images/gallery/".$fileName);

   print "Here's some more debugging info:\n";
   print_r($HTTP_POST_FILES);
} else {
   print "Possible file upload attack!  Here's some debugging info:\n";
   print_r($HTTP_POST_FILES);
}
print "</pre>";
?>

If I delete this part:

if(!preg_match('#^(gif|jpg|jpe?g|png)$#i',$type)){
  	unlink($HTTP_POST_FILES['userfile']['tmp_name']);
  	die('file was wrong image-type');
	}

then it works.

i suggest to check your "$type" variable
if your $type variable is full name file like image.jpg or photo.jpeg
or etc ...

its better and easy to you to separate their file full name to get
just the extension name, you can using explode() function for that

like $type=explode(".",$type)
after that you can using your function

if(!preg_match('#^{(gif|jpg|jpe?g|png)$#i',$type)){}
unlink($HTTP_POST_FILES['userfile']['tmp_name']);
die('file was wrong image-type');
}

good luck🙂
