I have a directory with files like such:

1-0.html
1-1.html
1-2.html
1-3.html
2-0.html
2-1.html
3-0.html
4-0.html
4-1.html

i want to make a page that will generate links to those. for example if a person is reading file 1-0.html, the links will display all the links for 1-0 to 1-3, but not show the other links.

currently I'm doing it by hand, but since I'm learning php, i thought there would be a way to do it with variables. :-)

is there a way to do that? or is there a better way for naming hierarchy to achieve a more or less automated result? if automated, is there also a way to change the css class of the current page? like the active page will be a gray color and non active link whereas the other links will be the regular link color?



Thanks.


update:

I found this: http://www.liamdelahunty.com/tips/ph..._directory.php it shows how to list files in a directory, but it seems to list everything in a directory. how can i do something similar but just to list certain files?

Thanks again.

In the for loop show 3 at a time and set the counter to let you know what is the next starting page

Should work

readdir will only return all contents. You have to then check all names (and type if dir could contain non-html or sub-directories). It's easily done with string functions - look at substr and strstr, Th example you found is checking that each filename doesn't start with a dot - ie that it isn't a hidden file.

I just wanted to give this a quick try:

PHP Code:

<?php
 
$current_group_id = 1;
 
$links = array();
 
if ($dir = dir('path/to/files/'))
{
  while ($file = $dir->read())
  {
    if (preg_match('/^' . $current_group_id . '-(\d+)\.html$/', $file, $match))
    {
      $links[$match[1]] = array(
        'file' => 'path/to/files/' . $match[0],
        'title' => 'Page ' . $match[1],
      );
    }
  }
}
 
ksort($links);
 
foreach ($links AS $link)
{
 
?>
  <a href="<?php echo $link['file']; ?>"><?php echo htmlentities($link['title']); ?></a>
<?php
 
}
