[RESOLVED] Fetch jpg files and list them

[Cambora]

Hi!

I want to search through a specified directory and fetch the filenames of JPG's and create a text link to them, so upon click it opens the correct picture. Any idea how to do this?

I also want a few other functions but those I already solved 😉

Here is a script I developed a while back to list certain files specified by the extension.

<?php

function getExFiles($path, $extension)
{
	global $files;
	if (is_dir($path))
	{
		if (substr($path, -1) == "/")
			$path = substr($path, 0, -1); //get rid of /
		$dh = opendir($path);
		while (($file = readdir($dh)) !== false)
		{
			if ($file != '.' && $file != '..')
			{
				if (is_dir($path."/".$file))
					getExFiles($path."/".$file, $extension);
				else
				{
					$pathInfo = pathinfo($path."/".$file);
					if (isset($pathInfo['extension']) && $pathInfo['extension'] == $extension)
						$files[] = $path."/".$file;
				}
			}
		}
		return $files;
	}
	else
		return false; //no point in continuing its not a directory bad call somewhere
}
$files = array();
$listFiles = getExFiles('/path/to', 'jpg');

This will only put the files within an Array so you will need to either loop through them again or modify the function and remove the server path e.g. /path/to/file.jpg to http://example.com/path/to/file.jpg etc.

Also since its a recursive function it will go through sub directories of the specified path.

First thanks for the code example! Can't get it to work though, I just added some print(); for troubleshooting. I can change the path to whatever I want (correct or faulty), it still just prints out:

Start of file

Looking in path: http://cambora.no-ip.com/test

End of file

The code below is the full code:

<?PHP
$path = 'http://cambora.no-ip.com/test';
$extension = 'jpg';
print("Start of file<P>Looking in path: $path<P>");

function getExFiles($path, $extension)
{
    global $files;
    if (is_dir($path))
    {
        if (substr($path, -1) == "/")
            $path = substr($path, 0, -1); //get rid of /
        $dh = opendir($path);
        while (($file = readdir($dh)) !== false)
        {
            if ($file != '.' && $file != '..')
            {
                if (is_dir($path."/".$file))
        	{
                    getExFiles($path."/".$file, $extension);
                    print("1<BR>");
                }
                else
                {
                    $pathInfo = pathinfo($path."/".$file);
                    if (isset($pathInfo['extension']) && $pathInfo['extension'] == $extension)
                        $files[] = $path."/".$file;
                        print("2<BR>");
                }
            }
            print("3<BR>");
        }
        return $files;
        print("Found: $files");
    }
    else
        return false; //no point in continuing its not a directory bad call somewhere
        print("Bad dir");
}

$files = array();
getExFiles($path, $extension);
Print("<P>End of file");
?>

Any ideas what might be wrong? And yes, I've searched for info and can't find anything... that's why I', posting here 🙂

[Edit]
The folder contains one jpg file (not an jpeg file, if that should make any difference)

That's your problem right there; [man]is_dir[/man] doesn't work on http URLs, partly because http responses are never directories (and http doesn't do stat()).

If this is on your machine, then you'd have better success using the actual file path to the directory.

Incidentally, most of the code given (except for the recursion) can be reduced by using [man]glob/man;

Indeed, that was my problem!!

Thanx for all the fast help, excellent!!
