API question

In the phpbb3 integration I have the ability to use a Gallery image as a forum avatar. In order for phpbb to convert the image to an avatar it must know where the source image is. Don't know if there is a better way to do this, but here is an excerpt of what I use and I think will do what you want.

$path = '';
$first_pass = true;

do
{
	list ($error, $items) = GalleryCoreApi::loadEntitiesById(array($itemId));

	$path_component = $items[0]->getPathComponent();
	$itemId = $items[0]->getParentId();

	if (!empty($path_component))
	{
		if ($first_pass)
		{
			$path = $path_component;
			$first_pass = false;
		}
		else
		{
			$path = $path_component . DIRECTORY_SEPARATOR . $path;
		}
	}
}
while (!empty($path_component));

$source = $gallery->getConfig('data.gallery.base') . 'albums' . DIRECTORY_SEPARATOR . $path;

Nice...thanks Alec!

Only thing I might add is that you get an array back and the path is contained in the second element, so the actual path would be in $myItemPath[1] in your example.

Thanks again...much better way to do it.

I don't think so. According to the docs (and also according to the code itself) the function returns

an array of (GalleryStatus status, string a path)

In my code the status is $ret, and $myItemPath is the string part. No requirement for further array dereferencing, and $myItemPath[0] would be incorrect.

Stephen: if you use this code then you should be aware (the docs make it clear) that path is only guaranteed to remain valid if the relevant locks are held.

I should be more explicit I think...

Eventually, I would like to run my script from the command line, i.e. 'php myscript.php', where it accepts the itemID for a media file (jpg, gif, etc..) as STDIN, and outputs the full system file path as STDOUT (or at least a path I can easily convert to a full path).

I can make a php file that uses require_once('./embed.php') etc... like in numerous embedding examples, and I get my gallery page just fine. I'm a bit confused as to where to put alecmyers code in. I can browse my gallery (without rewrites on) and navigate to a photo page, and then inspect the main image on that page. In the url I have 'g2_itemId=39' so I assume that image's ID is 39. If I put something like this in my file:

list ($ret, $myItemArray) = GalleryCoreApi::loadEntitiesById(39,'GalleryItem');
if ($ret) {
    echo 'Bollocks';
    exit;
}
list ($ret, $myItemPath) = $myItemArray[0]->fetchPath();
if ($ret) {
    echo 'Double Bollocks';
    exit;
}

I get 'Bollocks' back if I run through the web. I've tried putting it before and after the ::handleRequest, and there's no difference. If I run from the command line, I get nothing.

So I guess I have two questions now:
- What am I doing wrong? Is it not as simple as the code snippet you gave me?
- If I get this working through the web, how will I get it to work on the command line? Will I have to resort to using curl http://localhost/...?

Thanks for any additional help you can give me.

alecmyers,

here's what I get from the code in my previous post using getAsHtml() :

Error (ERROR_MISSING_OBJECT) : Entity with id [39] is a [GalleryDerivativeImage] and does not extend the required entity type [GalleryItem].

    * in modules/core/classes/helpers/GalleryEntityHelper_simple.class at line 129 (GalleryCoreApi::error)
    * in modules/core/classes/GalleryCoreApi.class at line 2347 (GalleryEntityHelper_simple::loadEntitiesById)
    * in cli.php at line 23 (GalleryCoreApi::loadEntitiesById)

So I put 'GalleryDerivativeImage' in place of 'GalleryItem' into loadEntitiesById, and then I get this error (the (...) is an edit by me):

Fatal error: Cannot use object of type GalleryDerivativeImage as array in (...)/cli.php on line 30

where line 30 is list ($ret, $myItemPath) = $myItemArray[0]->fetchPath();.

I then changed line 30 to list ($ret, $myItemPath) = $myItemArray->fetchPath();, and now it works! So in summary, this is a working code snippet, where of course for general items 39 gets replaced by $myID or whatever:

list ($ret, $myItemArray) = GalleryCoreApi::loadEntitiesById(39,'GalleryDerivativeImage');
if ($ret) {
    print $ret->getAsHtml();
    exit;
}
list ($ret, $myItemPath) = $myItemArray->fetchPath();
if ($ret) {
    print $ret->getAsHtml();
    exit;
}

echo $myItemPath;

So with respect to the command line stuff, you're probably right that it's a cookie issue. I thought I saw something somewhere about running embedded gallery2 without cookies, but it might be simpler to just accept I'll have to use curl, which I can make work, but it doesn't feel as elegant.

Thanks for help!
