Photo Gallery Question

[nonexistence]

I've been trying to figure out how to modify the microPhoto gallery from http://www.phptoys.com/e107_plugins/content/content.php?content.52 to read a subdirectory.

 

I assumed that I only needed to modify the line below

 

if ($handle = opendir(".")) { to

 

To something representing a subdirectory

 

if ($handle = opendir("gallery")) {

 

After modifying the two lines in the file, I can't get it to read the that directory.

 

I aslo modified the $dirName = '.'; to $dirName = 'gallery';

 

Could someone point me in the right direction?

No one can point me in the right direction? I want to be able to read a subdirectory. Any help is appreciated.

Try

if ($handle = opendir("./gallery/")) {

$dirName = './gallery/';

Didn't work. So frustrating, I've been looking at this code for about a week now and can't figure out why it won't open a subdir. 

 

I'm starting to believe the problem lies in this section of code, it's not properly displaying items because they aren't reading the subdir?

 

                  echo '</tr><tr><td class="photo"><a href="'.getNormalImage($file).'"><img src="'.$file.'" alt="'.$file.'"/></a></td>'; 

                  $act = 1;

              } else {

                  echo '<td class="photo"><a href="'.getNormalImage($file).'"><img src="'.$file.'" alt="'.$file.'"/></a></td>';

Don't feel like reading all the code...

 

 

But anyway, have you looked at the HTML?  Is it as it should be?

 

 

By the way, I suggest using other code.  That code is pretty bad.
