Help. Don't Know how images are being pulled w/ opendir & readdir

[flim_flamini]

Hi,

Can anyone help this newbie out? There is a page on the site I'm working on that has images lined up on the right side of the page. It appears that they are being grabbed by code I haven't come across before. I'd like to be able to change out the pictures and allow my client to change/upload the pics through their admin page.

 

Here is the part of code in question:

 

function file_type($file){
       $path_chunks = explode("/", $file);
       $thefile = $path_chunks[count($path_chunks) - 1];
       $dotpos = strrpos($thefile, ".");
       return strtolower(substr($thefile, $dotpos + 1));
   }
   $path = "award_images/";
   $file_types = array('jpeg', 'jpg', 'ico', 'png', 'gif', 'bmp', 'html');
   $p = opendir($path);
       while (false !== ($filename = readdir($p))) {
           $files[] = $filename;
       }
   sort($files);
       foreach ($files as $file) {
           $extension = file_type($file);
           if($file != '.' && $file != '..' && array_search($extension, $file_types)){
               $file_count++;
               echo '<tr><td><img src="'.$path.$file.'"></td></tr>';
           }
       }

 

Here is the entire code:

 

<table border="0" width="100%">
<tr><td>
<?

$tablename = "********".$header."_sterling";
//echo $tablename;
$optyear = mysql_query("SELECT DISTINCT awards_year FROM $tablename ORDER BY awards_year DESC");
while ($myoptyear = mysql_fetch_array($optyear))
{	
$distyear	= $myoptyear["awards_year"];	
//echo $distyear."<br>";
?>
<img src="images/bullet2.gif" alt="" width="11" height="11" /> <strong><font face="Arial, Helvetica, sans-serif" size="2"><? echo $distyear; ?></font></strong><br>
<?


$optsub = mysql_query("SELECT * FROM $tablename WHERE awards_year = '$distyear' ORDER BY awards_name ASC");

while ($myoptsub = mysql_fetch_array($optsub))
	{
$name	= $myoptsub["awards_name"];
$title	= $myoptsub["awards_title"];
$url	= $myoptsub["awards_link_url"];
$link	= $myoptsub["awards_link"];
$year	= $myoptsub["awards_year"];

if ($url !='')
{$imgcode = "<a href='$url' target='_blank'><u>$link</u></a>"; }
else	
{$imgcode = "";}
?>
<font face="Arial, Helvetica, sans-serif" size="2" >
<img src="images/bullet4.gif" alt="" width="9" height="11" /> 
<? echo ucwords($name); ?> <? echo $imgcode; ?><br>
<img src="images/spacer.gif" alt="" width="25" height="1" /> 
<? echo ucwords($title); ?>
<br>

<?
	}

echo "<br>";	
}


?>
</font>
</td>
<td height="100%">
<table height="100%">
<?
function file_type($file){
       $path_chunks = explode("/", $file);
       $thefile = $path_chunks[count($path_chunks) - 1];
       $dotpos = strrpos($thefile, ".");
       return strtolower(substr($thefile, $dotpos + 1));
   }
   $path = "award_images/";
   $file_types = array('jpeg', 'jpg', 'ico', 'png', 'gif', 'bmp', 'html');
   $p = opendir($path);
       while (false !== ($filename = readdir($p))) {
           $files[] = $filename;
       }
   sort($files);
       foreach ($files as $file) {
           $extension = file_type($file);
           if($file != '.' && $file != '..' && array_search($extension, $file_types)){
               $file_count++;
               echo '<tr><td><img src="'.$path.$file.'"></td></tr>';
           }
       }
?>
</table>

Erm.. not 100% sure of the "problem"..

Sorry I wasn't more clear. I don't understand how the code is grabbing the pictures in question, thus I'm not able to change said pictures.

It sets the directory to $path and gets all the files from that directory. Then it checks to see if the file is an img, if it is, it increments $file_count and echos out the html to show the picture with echo '<tr><td><img src="'.$path.$file.'"></td></tr>';.
