Getting folder list to automatically display with an image from each folder

[djkirstyjay]

Hi folks!

 

I'm new to this forum. I have been meaning to for a while, but am finally taking the plunge and trying to learn some meaningful PHP to help with a gallery I want to develop in order to display my kid's pics to my family.

 

I am a complete novice at this. I can understand HTML XHTML and CSS, but have only dabbled in PHP in the past in the form or the odd include.

 

I have kindly been given a bit of code from a friend of mine that will list pics within a foder, which will in tun link to the thumb of the pic as follows (I have a vague idea what it does, but that's about it) :

 

<?
class ListPics
{

function SetVars($folder)
{
$this->folder=$folder;
}

        function listFiles() {


                $dir = opendir($this->folder);

                $i=0;

                $imageNames=array();

                while ($file = readdir($dir)) {
                        $imageNames[$i][0]=$file;
                        $imageNames[$i][1]=strtolower($file);

                        $i++;
                }


                sort($imageNames);

?>
                  <table border=0 cellspacing=4 cellpadding="0">
                    <tr>
                      <?
                $k=4;
                for ($j=0;$j<$i;$j++) {

                        if ($j>1) {

                                        if ($k==4) {echo "<tr>"; $k=0;}



                                        $image='<img src="'.$this->folder.'/'.$imageNames[$j][0].'" border="0" alt="'.$imageNames[$j][0].'">';

                                        $sp = strpos($image,"TH");

                                        if($sp > 0)
                                        {

                                        //$bigpic = $imageNames[$j][0];

                                        $bigpic = eregi_replace("TH","",$imageNames[$j][0]);

                                        echo '
                                            <td valign="center" align=center><a href='.$this->folder.'/'.$bigpic.' target="_blank">'.$image.'</a></td>
                                         ';
                                        $k++;
                                        }



                                        if ($k==4) {echo "</tr>"; $k=0;};
                        }

                }
?>
                    </tr>
                  </table>
                  <p>
                  <a href="#top">back to top</a>
                  </p>
                  <?
        }



}
?>

 

 

That is fine for having the pics in a folder displayed in thumbnail form, which is then clickable to the larger pic, however what I also want to do is have a page where a list of the actual folders appears, but rather than displaying the folderlist, a thumb which will be named 'main.jpg' will display, which is then clickable to the page that displays the pics as the code above does.

 

Am I making sense? Can anyone give me a few pointers? I have been searching the web and am just getting more confused, so some laymans terms might be needed!

 

Any help would be greatly appreciated!
