Stumped on a search issue

[Xianoth]

Ok.. After getting my code working and all, I am going through the refining process after the feedback I am getting..

 

So, if you check out my previous post: http://www.phpfreaks.com/forums/index.php/topic,156919.msg682259.html#msg682259

 

You will see the synopsis of my project.

 

Now however I need to tweak the code on the backend of the user interface.

 

 

$input = $_POST['ext'];

$file_dir="./files";

$dir=opendir($file_dir);

while ($name=readdir($dir))

{

          if ($name != "." && $name != "..")

            if (strstr(strtolower($name), $input))

{

          echo "<a href=\"get.php?name=$name\" target=_blank>".$name."</a>";

          echo "<br />";

}

}

 

 

Now this works.. What I need to do is to add a character to the $name value. The inputs are extension numbers, and the filenames are saved with a "-" before the number in the filename. So say ext 111 would actually be -111 in the filename.  What would I have to do to modify my script to include a simple "-" ?

 

Any help is appreciated!  Thanks!
