I'm not sure if your question is as easy as it seems, but it seems like all you need to do is instead ofI have created a site in Joomla with a login (no self registration, users are provided with username and password by the admin). The users are supposed to login to a specific page where they can see 4 images. I have the following code: <?php // define directory path $dir = "images/user1/";
// iterate through files // look for JPEGs if (is_dir($dir)) { if ($dh = opendir($dir)) { while (($file = readdir($dh)) !== false) { if (preg_match("/.jpg/", $file)) { // read EXIF headers $exif = exif_read_data($file, 0, true); echo "<tr>"; // get thumbnail // link to full image echo "<td valign=top><a href=$dir/$file><imgsrc=thumbnail.php?file=$file></a><td>"; echo "<td valign=top><font size=-1>"; // get file name echo "File: <b>" . $exif['FILE']['FileName'] . "</b><br/>"; // get timestamp echo "Timestamp: " . $exif['IFD0']['DateTime'] . "<br/>"; // get image dimensions echo "Dimensions: " . $exif['COMPUTED']['Height'] . " x " . $exif['COMPUTED']['Height'] . " <br/>"; // get camera make and model echo "Camera: " . $exif['IFD0']['Model']; echo "</font></td>"; echo "</tr>"; } } closedir($dh); } } ?>
The question now is how to change the code to dimamically replace the folder name by the login username used. For example....if user2 logs in the images loaded will be only those in the folder images/user2, if user3 logs in it will be from the folder images/user3, etc... I am a little confused as to how to implement that in Joomla but as long as I have the code right I thinkI can just insert the code into the appropriate page using a mambot. If anybody here has any tips on how to accomplish that it would be extremely appreciated. Thank you in advance,

$dir = "images/user1/";
you go $dir="image/$username";
