I would like ActionScript 2.0 and PHP code that count the number of
JPEGs in a directory and return the resulting answer to Flash to be
used as an ActionScript Variable.

The ActionScript code should call the PHP code to ask it to count the
files, then the PHP script should count the files and return the
answer to ActionScript where it can be output as a text variable to
show the script is working.

My plans for the code:
I want to use this code to create a photo gallery that is easy to
maintain and update with fresh images. If my SWF file can know how
many JPEGs there are in a directory I won't have to edit the SWF file
every time I add or delete files from the directory as long as I
follow a naming convention for the JPEGs.

Hi, jugglerpm. Thanks for your question.

Flash and PHP make this task fairly simple. Using a short PHP script
and some simple Actionscript, you can get the number of files with a
specific extension in a directory.


The PHP script would have to contain:


<?

$imageDir = "/path/to/your/images";

$fileCount = 0;

if (is_dir($imageDir) && $directoryPointer = @opendir($imageDir)) {
	while ($oneFile = readdir($directoryPointer)) {
		$thisFileType = strtolower(substr(strrchr($oneFile, "."), 1));
		if ($thisFileType == "jpg" || $thisFileType == "jpeg") {
			$fileCount++;
		}
	}
} else {
	$fileCount = -1;
}

echo $fileCount;

?>



This script will return a single number giving the number of files in
the directory $imageDir (specified at the top) which end in either
".jpg" or ".jpeg".


You can get the value the script returns using a piece of actionscript like:


varObject = new LoadVars();

varObject.onLoad = function () {}
varObject.onData = function (dataIn) {
	numberOfFiles = unescape(dataIn);
}

varObject.load("filecount.php");


The 'onData' method is called when the php script has finished. The
variable numberOfFiles will contain the number the PHP script returns,
which should be the number of images.


If you have any questions, please request a clarification.

Hi Wildeeo, Thanks so much. Exactly what I wanted. -pm

It's very simple to this man !
Try to script a PHP that counts the JPG files in a directory you want
it's very simple It has it's own function to this for you.
After that create an instance of XMLSocket class.
It's connect function in your script should look like
MyXMLSokcet.connect("Your PHP script URL",80);
befor you call this function you must place EventHandler for onData method.
after this method calls it will receive the number of jpeg files that
the php script have found and returned.
