[SOLVED] check extension

[ballouta]

Kindly I need a reg that validates an uploaded file, it should always be .zip

(the name may contain numbers/letters/and dashes only)

 

Many thanks

~^[\da-z-]+\.zip$~iD

And you should also check if the file really is a ZIP, and not just a spoofed file with the zip extension. Code:

 

<?php
//$filedata is the data of the uploaded file
$start = substr($filedata, 0, 4);
if ($start == "PK\003\004") {
//data is ZIP file including packed files
} elseif ($start == "PK\005\006") {
//data is an empty ZIP file
} else {
//spoofed data, not a ZIP file
}
?>

Thanks for this important validation BUT the reg is not accepting a file name with space or letters or dashes, kindly may you edit it, wish i know who to do it

 

many thanks

Here you go:

 

~^[\da-z -]+\.zip$~iD

 

I just added a space inside the character class. And remember that whitespace not is allowed in an URL, so it would be a good idea to strip or convert any spaces when you save the file.
