[RESOLVED] Filter readdir() for .jpg directory display?

Joseph_Sliker

Hi;

I wanted a quick little script to show me small versions of image files in a directory along with their filenames.

I found a very handy bit of code in another thread (sorry...forgot which) that I tweaked a little and now it does ALMOST exactly what I want.

<?php 
echo "Images will display at 25% of their full size.";
echo "<table>";
if ($handle = opendir('.')) {
   while (false !== ($file = readdir($handle))) {
       if ($file != "." && $file != "..") {
           echo "<tr><td>$file</td><td><img border=\"0\" src=$file width=\"25%\"></td></tr>";
       }
   }
   closedir($handle);
echo "</table>";
}
?>

The only problem is, I would like it to read only files with the ".jpg" extension (there are a few other pesky/non image files that I want to keep in that directory as well.

Is there a simple way to apply a filter or mask for .jpg files using code such as I have here?

Thanks.

Since your not going into deeper directories. Why not use this code

<?php
foreach (glob("*.jpg") as $filename) {
   echo "<tr><td>$filename</td><td><img border=\"0\" src=$filemame width=\"25%\"></td></tr>";
}
?>

Will assume to be in the same directory when run, take a look at the [man]globa[/man] for more info on how to use it effectively.

That looks like a really sweet solution, but I tried it and it does not work. I'm wondering if it has anything to do with me being stuck on a Windows server?

I can't remember where I found this but it's useful.

You just parse directory and the file extensions you want to include and it'll store the filenames in an array.

function directory($dir,$filters)
{
	$handle=opendir($dir);
	$files=array();
	if ($filters == "all"){while(($file = readdir($handle))!==false){$files[] = $file;}}
	if ($filters != "all")
	{
		$filters=explode(",",$filters);
		while (($file = readdir($handle))!==false)
		{
			for ($f=0;$f<sizeof($filters);$f++):
				$system=explode(".",$file);
				if ($system[1] == $filters[$f]){$files[] = $file;}
			endfor;
		}
	}
	closedir($handle);
	return $files;
}

You could then use:

$filenames = directory(".", "jpg") //for multiple file types just separate the file extensions by commas
foreach ($filenames as $value)
{
echo "<tr><td>$value</td><td><img border=\"0\" src=$value width=\"25%\"></td></tr>";
}

YES!!!!

Works like a charm! ....once I figured out the semicolon was missing at the end of:

$filenames = directory(".", "jpg")

Thanks!

Weird; Windows shouldn't cause a problem (I use [man]glob[/man] quite a lot). You'd get an undefined function error if you're using something older than 4.3.
