alternative image source | folder

[ngrmm]

i have jpegs inside a folder (images).  the folder is located in the templates-folder of PW
site > templates > images

every 30 minutes a script generates  and saves jpegs into the images-folder. the all have a unique filename.
is it possible to save all those images into a image-field through API?
if not, is it possible to add the newest one into the imagefield?

i found this

$p = $pages->get(1001);
$p->of(true); // if in a template code, turn off output formatting
$p->images->add("http://placehold.it/350x150.jpg");
$p->save();
$p->of(false);

but i don't know how to grab the url automaticly of the newest file.

You don't need the URL, you also can use the filename, as the images are all in your webspace filesystem.

$imagedir = $config->paths->templates . "images/";

To grab the latest imagefile, you have to read and compare file timestamps, like last modified. Check PHP functions for that and directory iteration:

i was able to get it this was:

 

		$files = glob("../dir/*.*");
		$files = array_combine($files, array_map("filemtime", $files));
		arsort($files);
		$latest_file = key($files);

Not tested and not 100% sure, but you can remove one function:

$files = glob("../dir/*.*");
$files = array_combine($files, array_map("filemtime", $files));
$latest_file = array_pop($files);
