[Plugin: NextGEN Gallery] Can the tagcloud be in a sidebar widget?

Yeah, that would be nice!!

It really would.

Rughooking,

I got it to work with some code changes, provided both the tagcloud and its gallery are on the same page. Not sure that is what you are looking for. If you are, happy to share.

It involves a change to the nggfunctions.php file and a one line modification to the short codes (the version I had did not pass on the attributes from the shortcode).

With these changes, I can control the output of the shortcode:

[tagcloud show=cloud] shows the tagcloud only
[tagcloud show=gallery] shows the gallery only

I changed the default to show both. Not fully tested.

Also added a title into the gallery to indicate which tag is being shown. So if the target page/post is the same for both the tag cloud and gallery, it’s ok. I’m having a few more challenges with targeting the output to another page from an attribute. Different file, different set of parameters …

Seems as MaryE won’t be back to help out.

A couple of months ago a I tried to solve this with the help from others writing in this forum. This is what I came up with.

I created a sidebar widget with PHP code inserted.

First, make sure that you install the plugin Exec-PHP. There are other plugins that also enable PHP execution within posts and pages but I only tested it with Exec-PHP.

Next, create a page with the name and slug “picturetags” and put [tagcloud] into it.

Finally, paste the following code into a newly created text widget:

<ul>
<?php
$tags = (array) nggTags::find_tags($param, true);
foreach( $tags as $tag )
	{
	echo "<a href=../wp-content/nggallery/picturetags/?gallerytag=";
	echo $tag->slug;
	echo ">";
	echo "<li>";
	echo $tag->name;
	echo "</a>";
	echo ' ('.$tag->count.')</li>'."\n";
	}
unset($tags);
?>
</ul>

You will probably have to change this part according to your specific site setup:
“<a href=../wp-content/nggallery/picturetags/?gallerytag=”;

To avoid the page “picturetags” showing up at the front page I use the plugin PageMash wich can be used to hide certain pages.

To make the page “picturetags” somewhat more appealing I also pasted the following into it (before the [tagcloud] code)

<?php
$gallerytag = (get_query_var('gallerytag')); 		// get the slug
			$gallerytag = str_replace("-", " ", $gallerytag); 	// replace dashes with spaces
			$gallerytag = ucwords($gallerytag);					// capitalize words
                        echo 'The pictures below are displayed since you clicked the picture tag "'.$gallerytag.'". Click the image.';
			echo '<h3>'.$gallerytag.'</h3>'; 					// show the result
?>

<?php $tags = wp_get_object_terms($image->pid,'ngg_tag') ?>

<?php foreach ( $tags as $tag ) : ?>
   <a href="<?php bloginfo('url'); ?>/picturetags/<?php echo $tag->slug; ?>"><?php echo $tag->name; ?></a>
<?php endforeach; ?>

What I still didn’t manage to fix is a tagcloud with font sizes corresponding to number times a particular tag is used. Any help with this is appreciated!
