How To Page Directory Files?

eac

Hello, I am wondering how I can learn how to page the results that I get with the following code, which takes a dirctory and displays all the files. I would like to have 5/10 at a time. What would I have to do? Thanks

$maindir = "." ;
$mydir = opendir($maindir) ;
$files = array($mydir);
$exclude = array( "index.php",".htaccess","guarantee.gif") ;
while($fn = readdir($mydir))
{
if ($fn == $exclude[0] || $fn == $exclude[1] || $fn == $exclude[2]) continue; 
echo "<br><a href='$fn'>$fn</a>";
}
closedir($mydir);

If your next button is going to be on a form you could have hidden fields called firstFile, lastFile and then loop through the array until that filename is found and then show the next five.

If you are using sessions you could have the same info stored in the session and then the link to next could be a simple hyperlink, rather than a form.

No, it doesn't use sessions or forms

I would just love to have simple text linked paging of the directories (I said files, but I meant directories)

So if they are in the 'scripts' directory and scripts has 40 directories, I'd like to page each directory and open the file in each of those.

But to learn to do that, I use an example with pages in a directory. Just to create the paging process.

Is this possible?

Thanks

Course it's possible! Many many things are possible.

Then do what sarahk suggests, only have the fields written in the URL as a querystring.

<a href="listing.php?firstFile=5&lastFile=24">Next page</a>

or whatever.

Since you're going to use filenames instead of numbers, use urlencode() on them first before putting them in the link, so that URL-unfriendly characters in the file names don' slip through and mangle the link URL.

As for the paging process, sarahk has already given pointers on a good way to go about it.

Ok, so it dynamically will use an array to know how many files are there, and page accordingly, that is what you are saying? I am just new to this concept so physically creating it is a bit tough

I'll try and if I have problems I'll post back, if that's ok
