tex1820 Posted July 7, 2008 Share Posted July 7, 2008 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 Tex Quote Link to comment Share on other sites More sharing options...
rhodesa Posted July 7, 2008 Share Posted July 7, 2008 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; ?> Quote Link to comment Share on other sites More sharing options...
