SC getpathcomponent problem

[Huidong]

I'm trying this command to get the file extension, but somehow, when I use it inside a for loop via <allitems>, I get an extra right-quote in the result.

Code: Select all

foreach( $item, <allitems>, " " ) {
    $ext = getpathcomponent($item, "ext");
    echo $ext;
}

I get something like

Code: Select all

MP4"

But

getpathcomponent($item, "base");

works fine.

[EDIT]
I just noticed that, instead of using <allitems>, if I use get("ItemsPathNames"), then getpathcomponent($item, "ext"); worked!

This is not a bug of gpc().

It's a problem caused by using the wrong delimiter for foreach() / having a space in a path / item name

Unquoting the items would work but you would still be in trouble if you have space inside one of them...

Code: Select all

    foreach($item, <allitems>, " ") {
        $ext = getpathcomponent(trim($item, '"'), "ext");
        echo $ext;
    }

So the correct solution would be:

Code: Select all

    foreach($item, <allitems>, '" "') {
        $ext = getpathcomponent(trim($item, '"'), "ext");
        echo $ext;
    }

Moving this topic now...

Thanks a lot, highend:) Now I understand what <allitems> actually is -- it includes *literal* quotes around each individual path, and thus if it's split using only a space, each item will not be a valid path, as paths should not include those literal quotes!

And thanks for taking the time to offer the nice workaround to fix the issue. But I guess in general, I've learned that for iteration, using the get function is way better!
