Problem with funny file names

It seems that files with funny, windows valid, names don't get handled well by resizer.

The file name "joe's & Test1's.1600x1200.jpg" seems to break resizer.

Along with handling that, it would be nice if file names could be specified with the upload behavior. If the client could upload the file joe's & Test1's.1600x1200.jpg and I could rename it, upon upload, to PostImage_[RecordId].jpg, I could avoid this problem entirely.

although apostrophes and ampersands are valid in file names on Windows systems, they are not valid file names on the web and should be avoided.


you can strip those characters on file upload using the following code on your upload page:

<?php

if(isset($_FILES)) {

    foreach($_FILES as $k => $v) {

        $_FILES[$k]["name"] = str_replace(array("&","\\","'"),"",$_FILES[$k]["name"]);

    }

}

?>

Thanks Jason,

I wanted to point this out because I think the extension should handle this for you.

One might want to add quotes, ampersands, ?,<,>,*,etc to the list to be safe as well as the pipe character. Some of those are not allowed on windows either, but it doesn't hurt to be safe.

Accented chars should also be replaced with equivalents.

It would also be nice to optionally replace spaces with dashes. and the suggestion above about having an option to rename the file by a formula like PostImage_[RecordId].jpg

The file I've attached will also strip the accents and other special characters. I use it for generating seo links, but by allowing periods, it will work for this purpose as well. It is from several functions which can be googled and updated a bit for my purposes.

The code to use it would be:

<?php
require_once("generateSafeLink.php");
if(isset($_FILES)) {
    foreach($_FILES as $k => $v) {
        $_FILES[$k]["name"] = generateSafeLink($_FILES[$k]["name"],array(),false,true);
    }
}
?>
