Can not limit file type in uploads.

[dvdljns]

I am trying to write a file upload script. It uploads files just fine now it is time to limit the type of file uploaded. here is the code I am trying to use.

if (!($uploaded_type="archive/zip")) {
echo "You may only upload zip files.<br>";
$ok=0;
} 

 

This is the first php script I have wrote and thought I understood what I was doing but what happens is it uploads the file then tells you it uploaded ok then tells you it can only upload zip files. I want only compressed files uploaded. how do I do this.

Use double equals for comparison. A single equal sign is used for assignment

The type sent for a zip file is different depending on the browser used. Here's what I get for the following browsers I tested with:

Chrome v4.1.249.1064:

Array
(
    [userfile] => Array
        (
            [name] => 0_to_99_markers.zip
            [type] => application/octet-stream
            [tmp_name] => D:\xampp\xampp\tmp\php1DA7.tmp
            [error] => 0
            [size] => 161036
        )

)

 

Firefox v3.6.3:

Array
(
    [userfile] => Array
        (
            [name] => 0_to_99_markers.zip
            [type] => application/zip
            [tmp_name] => D:\xampp\xampp\tmp\phpE5D6.tmp
            [error] => 0
            [size] => 161036
        )

)

MSIE8

Array
(
    [userfile] => Array
        (
            [name] => 0_to_99_markers.zip
            [type] => application/x-zip-compressed
            [tmp_name] => D:\xampp\xampp\tmp\php8273.tmp
            [error] => 0
            [size] => 161036
        )

)

 

Opera v10.53

Array
(
    [userfile] => Array
        (
            [name] => 0_to_99_markers.zip
            [type] => application/zip
            [tmp_name] => D:\xampp\xampp\tmp\php117A.tmp
            [error] => 0
            [size] => 161036
        )

)

I thought it was decide by the os I never thought of checking to see what the browser was sending thanks. Let me try it with the new info.

 

How was it done on here does anybody know. this would be something like I am looking for.

 

Allowed file types: zip,bz,gz,tar.

Dont validate by mime instead validate by extracting the extension from $_FILES['file']['name']
