xml.php creation of Media RSS feed from Gallery2 albums

Ok I got this to work using the original xml.php file and added the following to the theme.tpl

I will test it on other machines to see if this works flawlessly. it is slow nonetheless.

For me too !
Just modifiying theme.tpl (for Matrix) and adding xml.php at root of Gallery2.
Nice !

P.

I posted a further update to my original xml.php which natec did an excellent job modifying for use with Piclens.
picLensRss.php is used exactly the same way as xml.php and works perfectly.

• As usual just edit line 30 to reflect your setup.
• Edit theme.tpl add these lines:
  

  {if $theme.pageType == 'album'}
      <link rel="alternate" type="application/rss+xml" title="PicLens RSS" href="/gallery2/picLensRss.php?g2_itemId={$theme.item.id}" id="picLensGallery"/>
      <script type="text/javascript" src="http://lite.piclens.com/current/piclens.js"></script>
  {/if}
  

• Edit album.tpl add these lines (I put them next to the original slideshow button):
  

  <td class="gsActionIcon">
      <div class="buttonViewSlideshow"><a href="javascript:PicLensLite.start();"></a></div>
  </td>
  

Works per image in an embedded G2.(meaning the arrow that shows on the images)
Works full featured in Standalone G2 Browser button, secondary slideshow button and per image as well.

This picLensRss.php has many more functions than xml.php for easier customization.

natec, please update to piclens 1.6.1 for safari, my partner assures me it is working for safari now although its in beta still.

thats what I was referring to above.

When I have more time, I'll look into the embedded G2 issue.

-s
FlashYourWeb and Your Gallery with The E2 XML Media Player for Gallery2

there are 2 ways to get your "medium" image:

1. Get the preferred image:
   

   function getPreferred($item) {
   	$id = $item->getId();
   	list ($ret, $preferred) = GalleryCoreApi::fetchPreferredsByItemIds(array($id));
   	if ($ret) {
   		return array($ret, null);
   	}
   	if (isset($preferred[$id])) {
   		return $preferred[$id];
   	} else {
   		return $item;
   	}
   }
   

2. Get best fit by dimension contributed by Kirk(g2image)
   

   function getBestImageId($masterId) {
   	global $gallery;
   
   	if (isset ($_REQUEST['g2_maxImageHeight'])) {
   		$maxImageHeight = $_REQUEST['g2_maxImageHeight'];
   	}
   	if (isset ($_REQUEST['g2_maxImageWidth'])) {
   		$maxImageWidth = $_REQUEST['g2_maxImageWidth'];
   	}
   
   	$potentialImages = array();
   
   	//how about the original?
   	$ret = GalleryCoreApi::assertHasItemPermission($masterId,'core.viewSource');
   	if (!$ret) {
   		//is there a preferred derivative of the original?
   		list ($ret, $preferred) = GalleryCoreApi::fetchPreferredsByItemIds(array($masterId));
   		if ($ret) {
   			return array ($ret,null);
   		}
   		if (!empty($preferred[$masterId])) {
   			$potentialImages[] = $preferred[$masterId];
   		} else {
   		//if no preferred, use the original	original
   			list ($ret, $item) = GalleryCoreApi::loadEntitiesById($masterId);
   			if ($ret) {
   				return array ($ret,null);
   			}
   			$potentialImages[] = $item;
   		}
   	}
   	// If the user can see resized versions consider those too
   	$ret = GalleryCoreApi::assertHasItemPermission($masterId,'core.viewResizes');
   	if (!$ret) {
   		list ($ret, $resizes) = GalleryCoreApi::fetchResizesByItemIds(array($masterId));
   		if ($ret) {
   			return array($ret,null);
   		}
   		if (!empty($resizes)) {
   			foreach ($resizes[$masterId] as $resize) {
   				$potentialImages[] = $resize;
   			}
    		}
   	}
   	//can always use the thumbnail
   	list($ret,$thumbs) = GalleryCoreApi::fetchThumbnailsByItemIds( array($masterId) );
   	if ($ret) {
   		return array ($ret,null);
   	}
   	$potentialImages[] = $thumbs[$masterId];
   
   	//true if maxDimensions are taller/narrower than image, in which case width is the constraint:
   	$widthbound = ( !$maxImageHeight || $potentialImages[0]->height * $maxImageWidth < $potentialImages[0]->width * $maxImageHeight ) ? 1 : 0;
   
   	usort($potentialImages, "byWidth");
   
   	if ( $maxImageWidth &&  $widthbound ) {
   		foreach ($potentialImages as $potentialImage) {
   		if ($potentialImage->width >= $maxImageWidth) {
   			return array ( null, $potentialImage);	//return the first one wider than $maxImageWidth
   		}
   			}
   	}
   	elseif ( $maxImageHeight ) {
   		foreach ($potentialImages as $potentialImage) {
   		if ($potentialImage->height >= $maxImageHeight) {
   			return array ( null, $potentialImage);	//return the first one taller than $maxImageHeight
   			}
   		}
   	}
   	$bestImage=array_pop($potentialImages);
   	return array( null,  $bestImage);			//none of them big enough - use the largest
   }
   
   function byWidth($a, $b) {
   	if ($a->width == $b->width) return 0;
   		return ($a->width < $b->width ) ? -1 : 1;
   }
   

   this one you would need to pass 2 more vars in your request g2_maxImageHeight, and g2_maxImageWidth.

Not necessary until I get a chance to look into the embedded gallery issue.

ok I've added the bestFit mod.
edit line 30....
one small change to theme.tpl

<link rel="alternate" type="application/rss+xml" title="PicLens RSS" href="/gallery2/picLensRss.php?g2_itemId={$theme.item.id}&g2_maxImageHeight=600&g2_maxImageWidth=600" id="picLensGallery"/>

Add your maxImageHeight & maxImageWidth
this will still function as normal if you leave them out.

I also fixed something I omitted from function getPreferred in the original. So that should work as well.

Edit 3/9/08
Fixed some script errors - thanks Gernot ;)
I updated the zip on mysite so get it there.(removing the one here)

FYI, I just committed a change today to add PicLens (and LyteBox as a fallback) to the slideshow module in 2.3. Get the latest nightly download and you'll get a nice full-screen PicLens slideshow when you click the "View Slideshow" link. Enjoy!

@All:

I guess* xml.php is not needed anymore. With G2.3's slideshow module you'll get a MediaRSS feed right out of the box.
You can try the current nightly snapshot of G2.3.

*) I don't know xml.php and its applications very well. But I assume that its just a MediaRSS feed.

Documentation: Support / Troubleshooting | Installation, Upgrade, Configuration and Usage

PicLens Demo: http://www.menalto.com/gallery/family/Disneyland2007/ and click on "View Slideshow"

LyteBox fallback demo: http://www.menalto.com/gallery/main.php?g2_view=slideshow.Slideshow&g2_itemId=54009

Looks to me like the LyteBox version needs to have a longer delay. What do you guys think?

Hello Suprsidr,

I am using your mediaRSS.php to pull the feed from my gallery2. LOVE IT!
I do have a quick question. What I want to do is create an album in gallery2 that is a "Best Of.." so to speak.
However, I want the album to be Hidden. In other words I am only using it for the feed, visitors to my Galler2
cannot see it. The problem is that when it is set to 'hidden' IE7 & FireFox is not returning the feed, while
IE6 does return it.

So, I guess the question is, is there a flag I can set in the mediaRSS.php that will still return the hidden
gallery album feeds? Or, do albums have to be visible to get the feed?

Thanks for your time and I appreciate your hard work.

Banta

@valiant

• When embedded PicLens only works via the icons that appear on each image. Not via the browser button.
• When embedded LyteBox appears about 2 feet down the page... keep scrolling its there.

Confirmed in firefox 2.x and IE7
Both work perfectly standalone - Great work

I was actually hoping you guys had more advanced info on this as I spent a couple hours trying to figure out where the problem lies while embedded.
(most likely the image src does not match the link)
The PicLens problems are the same I ran into, the LyteBox issue is new to me.

@Banta Hidden albums change the view permissions. You need Everybody [core] View all versions.

I updated the slideshow module only - same issue
found a clue in my errorlog:

looks like the slideshow is trying to include something from the modules directory but not detecting the embed correctly as it should be /gallery2/modules

If you would like me to do aother complete upgrade let me know.

On another note. I noticed when using Matrix theme I get PicLens when I click the slideshow link, but with Carbon I get LyteBox even though the view is the same:
g2_view=slideshow.Slideshow&g2_itemId=32
Should'nt I always get PicLens?

the piclens flash slideshow works fine in YOUR embedded gallery, just use the slideshow link from the sidebar. i'll fix carbon's mini icon link as soon as i got it reviewed.

that's too old. as i said above, the fix was from Wednesday.

the fix for the carbon theme is in now too (requires a core and carbon upgrade).

@Suprsidr
THANKS!!
It works fine now! Great!
I'm just a bit confused since my integration Wordpress+iTheme for WP+Gallery2+WPG2+Piclens seems not being very stable. That's frustrating because I had a problem (not able to open the gallery part...) that I only solved with a complete desactivation and re-activation of all that (don't know how to analyze and point out the problem). But for now it works fine

@Bharat
I see your work in action on your site. It's GREAT to know that it will be integrated in the next release of gallery.
For the reason mention above, I will not begin with the nightly compiled version( I don't even know how to do that ;-) ) for the moment ;-).

THANKS
Tom

This one works better.
But if you read the rest of this thread, this feature is now available in a nightly build of Gallery ;)

FlashYourWeb and Your Gallery with The E2 XML Media Player for Gallery2

@Gernot, check your webserver's errorlog for clues.
But I must say the latest nightlies are superb ;)

FlashYourWeb and Your Gallery with The E2 XML Media Player for Gallery2

@tomtomgoo:
you don't need piclens. you can use the media-rss feed of the new slideshow module with other slideshow tools as well. i guess you can use it with flash4web's slideshow tool as well.

> I'm looking for some informations about the 'nightly builds'.

you can get the nightly snapshot from the downloads page, we call it "latest experimental code" there.
it's like any other upgrade. see: FAQ: How to upgrade Gallery2?

Documentation: Support / Troubleshooting | Installation, Upgrade, Configuration and Usage

Apparently not.
Its checking to see if the imageBlock disabled flag is set for each album.
You can set that function(function getDisabledFlag) to always return false.

-s

function getDisabledFlag($itemId) {
    return false;
}

Can someone please tell me exactly where to put this in album.tpl? (X_treme)

Thanx

I've already included

in theme.tpl.
My problem is, I can't find the stock slideshow button in album.tpl...going crazy....

Where do I download nightly build?

Thanx

Hi all!
I now successfully tried the latest (well, 1 week old) nightly build and does work superbly, just as suprsidr said! I really see all the pictures in what seems to be the best available resolution, and none of them are skipped (with the manual mediaRss.php hack, some were skipped)
So I will lean back now and joyously await the 2.3 release of gallery!
I'll go now see if I can contribute to the 2.3 release...
thanks to all!

Finally and thanks to bharat my wordpress-gallery site is back ;-).
I've just tried to erase my Piclens.rss file and the corresponding lines in the theme.tpl file and have to say that I'm disappointed (a little) :
- the button which appeared directly on the images is no longer present (don't know if it's normal)
- Don't succeed to get the slideshow button on the sidebar (I have to go in 'operations' and choose slideshow; maybe that's due to the wordpressembebed theme but I'm sure I have seen it before...)
- seems not to get the 800x600 images (don't know how to be sure but the time to get a detail picture is much longer)
- the 3D wall only appears when all the little pictures are downloaded (we could see it directly, pictures dowloading)
- The client needs to get the plugin to be able to see the 3D wall (= was what I was wondering)

Tom

The latest nightly is very stable no worries there.
