get files from a folder

theprofession

What i want to is have a folder where i can put an html file and then have it appear on another page with a link as a headline. How can i go about this? I also want like only 5 to appear as headlines and then have a view more link that shows all of them.

From the php documentation here
http://php.net/readdir

i found this:

<?php
$the_path = '/path/to/files';
if ($handle = opendir($the_path)) {
  while (false !== ($file = readdir($handle))) {
    echo "$file\n";
  }

  closedir($handle);
}
?>

thanks only problem i have is just getting the files to show for some reason its not showing, But i appreciate the help.

perhaps you could show us what you did with the code. did you change the path so that it points to the folder you'd like to list?

theprofession

thats what I did


<?php
$the_path = 'public_html/lounge/feat';
if ($handle = opendir($the_path)) {
  while (false !== ($file = readdir($handle))) {
    echo "$file\n";
  }

  closedir($handle);
}
?>

Installer

If you have the script you posted in your public_html (web) directory or a directory under that one then the path you give is wrong. It should be, in the first case, 'lounge/feat' or, in either case, $_SERVER['DOCUMENT_ROOT'] . 'lounge/feat'. And if you don't get a message telling you that the path is invalid (thus telling you immediately what the problem is), it's because you don't have error_reporting enabled.

So if you got errors, you should ALWAYS post them here. It's really helpful to know what exactly "isn't working" means.

Try this modified one...it might help you figure out what your path should be by reporting some information. It also displays an error message if you can't open your path.

<?php
// it might be helpful to know where the current file is located
// in order to properly enter the path of your directory:
echo 'THIS FILE:' . __FILE__ . '<br>';

// since you gave a relative path rather than an absolute path
// it is going to be evaluated relative to this path location:
echo 'the current working directory is ' . getcwd() . '<br>';


$the_path = 'public_html/lounge/feat';
if ($handle = opendir($the_path)) {
  while (false !== ($file = readdir($handle))) {
    echo "$file\n";
  }

  closedir($handle);
} else {
  echo 'UNABLE TO OPEN ' . $the_path . '<br>';
}
?>

Ok so this is what happens:

http://a.parsons.edu/~dpaul/lounge/featured.php

It gets the directory and everything.

Well hooray.

Sounds like you want to use [man]glob[/man] instead of [man]opendir/man/[man]readdir/man with a pattern like ".html" (or, if you have both .html and .htm files, ".{htm,html}" with the GLOB_BRACE flag).

It most certainly is. In fact, one user contributed a function that does exactly this.

theprofession

<?php
foreach (glob("*.txt") as $filename) {
   echo "$filename size " . filesize($filename) . "\n";
}
?>

when I use this it doesnt goto the next line in the output...

Are you sure? If you're viewing the results in a browser, try viewing the source code of the page - I bet you'll see the new lines you're looking for.

Ok i change this up a bit and got it to work just trying to get the last modified to appear at the top. So I am messing around with the function.

I'm not sure but i changed up the code instead of using "/n" i used br to replace it.

If you're still having trouble getting the last modified file at the top, have you followed the link I posted back in February?
