Hi all, my name is tex. I'm new to php. I started to write my first real self made php script however im starting to run into problums. here is what I have so far. The top part of the code came from this website

 

http://snipplr.com/view/4147/count-number-of-files-in-a-directory/

 

I am using it to create a simple web gallery. here is what I have so far:

 

<?
      $dir = "gallery";
      $count = 0;
      if(is_dir($dir)) {
      if($handle = opendir($dir)) {
      while(($file = readdir($handle)) !== false) {
      $count++;
      }
      closedir($handle);
      }
      }
      echo $count;
      
  while ($count > '0')
  {
  	?>
        <a href="gallery/<?php echo $count; ?>.gif"><img src="gallery/<?php echo $count; ?>.gif"></a>
        <? 
	$count--;
	}
	?>

 

Now the thing is, it is finding the images but it says there are 5 images, however there are only 3 in the dir. here is another example:

http://monty.triplethreatairsoft.com/gallerymessedexample.php

 

I left the number to show that it is seeing 5 files. Also why will the images not load? I have a shot in the dark, the php stops loading the images when it loops. am I right about that? how can i fix it? thanks everyone, when it is 100% done, I will be shour to share it :)

when you are reading the list of files in a directory (either with readdir() or scandir()) you will always get 2 'extra' entries. They are '.' and '..'

. => Current directory

.. => Parent directory

 

you need to add logic in your code to skip these entries. i usually skip anything that starts with a period since (for the most part) anything that starts with a period should be a system/hidden/etc file

 

<?php //I would recommend using full PHP tags as not all PHP installs will have short tags enabled
      //Also, try getting in the habit of indenting...it's much easier to read
      $dir = "gallery";
      $count = 0;
      if(is_dir($dir)) {
            if($handle = opendir($dir)) {
                  while(($file = readdir($handle)) !== false) {
                        if($file{0} == '.') continue; //This line skips files that start with a period
                        echo "<a href=\"{$gallery}/{$file}\"><img src=\"{$gallery}/{$file}\"></a>\n";
                  }
                  closedir($handle);
            }
      }
      echo $count;
?>
