[RESOLVED] how to dynamically display choices from files in a directory?

[schwim]

hi there everyone,

I'm trying to give my script the ability to use language files, and I seem to be doing a-ok with actually getting the script to use a language file, so that's not a problem, but I want the user to be able to drop a lang file into a selected directory, and have it show up automatically in a dropdown in the configuration section of the script.

Say they download the DE language file, and want to use it in their script. I want them to drop it into /includes/languages and then be able to go to their configuration panel, and have it available as a choice automatically.

What would be the best way to do this?

thanks,

function getLanguages($dir='/includes/languages') {
  $dir = $_SERVER['DOCUMENT_ROOT'].$dir;

  $dh = dir($dir);
  if(!$dh) return('Unable to open Directory');

  while(false !== ($item = $dh->read())) {
    if($item != '.' && $item != '..') {
      $files[] = $item;
    }
  }

  $dh->close();

  if(empty($files)) return('No Languages to select from');

  $output = '<select name="language">';
  foreach($files AS $lang) {
    $output .= '
    <option value="'.$dir.'/'.$lang.'">'.$lang.'</option>';
  }
  $output .= '</select>';

  return $output;
}

echo getLanguages();
// To specify in another directory other than "/includes/languages"
echo getLanguages('/program/themes/languages');

Something as simple as reading the directory file-tree would do, i.e. just like above.

Hi there Brad,

Thanks very much for your help. I have two questions though concerning this:

1) Is there a way to strip ".php" from the result that is in the dropdown?

2) How can I get the script to default to the one that is currently selected? If the value retrieved from the db is english, then I'd like english to show as the default language when the configuration page is generated.

I've altered the script very slightly, just because it's a script that will get used on a lot of different servers, so I integrated the sitepath var into it:

	function getLanguages() {
		global $sitepath;
		$dir="$sitepath/includes/languages";

	$dh = dir($dir);
	if(!$dh) return('Unable to open Directory '.$dir.'');

	while(false !== ($item = $dh->read())) {
  		if($item != '.' && $item != '..') {
  			$files[] = $item;
		}
	}

	$dh->close();

	if(empty($files)) return('No Languages to select from');

	$output = '<select name="language">';
	foreach($files AS $lang) {
		$output .= '
		<option value="'.$dir.'/'.$lang.'">'.$lang.'</option>';
	}
	$output .= '</select>';

	return $output;
}

thanks,

1.) [man]substr[/man]($string, 0, strrpos($string, '.'));
2.) Easy, in the loop, compare the file-name with the current language 😉

function getLanguages() {
  global $sitepath, $language; // Include sitepath and current language
  $dir = $sitepath.'/includes/languages';

  $dh = dir($dir);
  if(!$dh) return 'Unable to open directory: '.$dir;

  while(false !== ($item = $dh->read())) {
    if($item != '.' && $item != '..')
      $files[] = $item;
  }
  $dh->close();

  if(empty($files) || !isset($files)) return 'No languages to select from.';

  $output = '<select name="language">';
  foreach($files AS $lang) {
    $display = substr($lang, 0, strrpos($lang, '.'));
    $selected = ($language == $lang) ? ' selected="selected"' : '';

$output .= '
<option value="'.$dir.'/'.$lang.'"'.$selected.'>'.$display.'</option>';
  }
  $output .= '</select>';

  return $output;
}

That should incorporate all your modifications. Now, if $language isn't set elsewhere or is a global (like held within $_SESSION) then you need to modify the above code just slightly.

Hi there Brad,

Thanks very much, from start to finish, that works great.

I had the same problem with radio buttons and asked on this forum, but I couldn't figure out how to implement that fix to a drop down... that worked perfectly.

Thanks very much for your help!
