3B-2 Directory Navigation Script

The test directory link does not open. Any idea what I'm missing in the code?

Try using @extract($_GET); or $dir = $_GET['dir'];

The <a href='?dir=./Test'> means that you are passing the $dir variable via the url hence the need to use @extract($_GET) ????? Hope this is the right explaination.

@extract($_GET); does the trick. Task now complete. Tanx Sandile

With older versions of PHP, if you created a form with a field name of say "name", PHP would automatically have created a variable "$name" on the next page. Same if you did send it through the URL. Not anymore.

So you have to "fecth" the variable now, using $_POST or $_GET. But you have to do that with each one. @extract automatically extracts all at once. Which is nice.

Remember, you can link back to many previous forums (2006 forums on top of forum list) for a wealth of information. We use the same manual each semester so your questions may already have been answered elsewhere.

looks like i am on track. i have caught up and am on schedual. Sweet

Quick Q Mac:
The php code for this task only opens a set directory and then makes
url's for all the items found in that directory...
Is it possible that that you can open a directory urself and browse to
find a specific item?

Hope my q is clear enough..

but i have to give the credit to the guys that post over at php.net this isnt
the prittiest of code but it is rather late... njoy*/

If I get your Q, a directory can only be browsable (in the manner of a filemanager) if it is defined so on the server, typically in the httpd.conf file. If you can do it with code, then there are security gaps on the server!

point noted mac. we don't want no security issues...
