list and/or count filetypes (*.jpeg)

[jammo]

hey all.

i am using the following function to count the number of files in a specified directory:

//=> Opens specified DIR and counts the files or folders within it.
function getFileCount ($type,$dir='./'){
		if (($type == 'file') || ($type == "link") || ($type == 'dir')) {            
		  if (is_dir($dir)) {      
			$fd = opendir($dir);
			while ($part = readdir($fd)) {
			  if ($part != "." && $part != "..") {
				clearstatcache();
				$function = 'is_' . $type;
				if ($function($dir . $part))  {
					$count++;
				}                    
			  }                
			}                                         
		  }else{ $err = $dir . ' is not a directory'; }   
		}else{ $err = $type . ' is unknown type -- must be file,link or dir'; }                 
		if (isset($err)) {   
			Return $err;
		}else{
			Return $count;
		}
		/*-
		Example Use
		print getFileCount('file','thumbs/');   
		print getFileCount('file','full_size/');   
		-*/
}

it works file. except im having trouble making it show ONLY jpeg files.
im using this for a gallery im writing.

i have something like this on my index.php page:

	if ((getFileCount('file',"$file/")) < (getFileCount('file',"$file/thumbs/"))) {
	echo "too many thumbs";
	}elseif((getFileCount('file',"$file/")) > (getFileCount('file',"$file/thumbs/"))) {
		echo "<a href=\"thumb.php?file=$file\">Make Thumb</a>";
	}elseif((getFileCount('file',"$file/")) == (getFileCount('file',"$file/thumbs/"))) {
		echo "DONE!";
	}

the function should count the number of files in the FULL_SIZE directory and also the THUMBS directory.
if FULL_SIZE == THUMBS, then nothing needs to be done.

but if FULL_SIZE > THUMBS, then thumbnails need to be created.
<< with the code posted here in my other thread: http://www.sitepoint.com/forums/showthread.php?t=211101 >>

then i came to realize that the thumb.php file needs to reside in the FULL_SIZE folder and i got it to create the THUMBS folder, if it doesnt already exist.


my problem is that i am trying to get my getFileCount function to ONLY count the jpegs.


any help would be dearly appreciated.

Well what about haing an if condition to count the second index of the getimagesize() function? Look up the predefined IMAGETYPE constant.

Hi

simple enough...


Here is a simple example for you!


As a function!

<?

function this_ext ( $file )
{
    return substr ( $file, strrpos ( $file, "." ) + 1 );
}


function get_total ( $dir, $match )
{
    $out = 0;

    if ( $dh = opendir ( $dir ) )
    {
        while ( false !== ( $file = readdir ( $dh ) ) )
        {
            if ( $file != "." && $file != ".." )
            { 
                if ( is_file ( $dir . $file ) && in_array ( this_ext ( $file ), $match ) )
                {
                    $out++;
                }
                        }
            }

        closedir ( $dh );
         }

       return ( $out );
}


// unix, the directory you are counting the content from! (include the trailing '/')

//$path = "./path/www/docs/";


// windows, the directory you are counting the content from! (include the trailing '/')

$path = "e:/www/docs/img/";


// an array of files to count!


$count = array ( 'jpg', 'jpeg' );


// call the function....


$total = get_total ( $path, $count );

// show the results...

echo $total;

?>

J!

PS: I made a mistake earlier, I meant third index of the getimagesize() function, not second

jbr's code would work, but it won't always be 100% accurate as far as I can see because a gif can have a .jpg extension. It's the header of that image that actually determines what type it is...so if you want to be 100% sure your images are jpg's you should use getimagesize() IMO

I just modified your code a bit jbr, I hope you don't mind

<?php
    function get_total($dir, $allowedTypes = array())
    {
        $out = 0;
        if($dh = opendir($dir))
        {
            while(false !== ($file = readdir($dh)))
            {
                if($file != "." && $file != "..")
                {
                    list($width, $height, $type, $attr) = getimagesize($file);
                    if(is_file($dir . $file))
                    {
                        foreach($allowedTypes as $allowed)
                        {
                            switch($allowed)
                            {
                                case $type:
                                        $out++;
                                    break;

                                default:
                                    break;
                            }
                        }
                    }
                }
            }
            closedir($dh);
        }
        return $out;
    }


// unix, the directory you are counting the content from! (include the trailing '/')

//$path = "./path/www/docs/";


// windows, the directory you are counting the content from! (include the trailing '/')

$path = "e:/www/docs/img/";


// an array of files to count!



// call the function....
//See: http://www.php.net/getimagesize/ for more
$count = array(    2    /*JPG*/,
                10    /*JP2*/);
$total = @get_total( $path, $count );

// show the results...

echo $total;

?>

PS: Calling the function prepended with an '@' will set PHP in silent mode for that call and any warning messages will not be displayed.
