(Note added 3/21/2011 – This article describes how to have one component output different html for different sections of a website.  New in Joomla 1.6 is the ability to do this with named alternative  overrides that can be selected as a parameter.  I’ll be posting about that soon!)

For  the negreenhouseupdate.info site   I used the extension “Imagesized”  to have large images resized when they appear in a blog layout.   This allowed me to have photo gallery content items with large image, and lengthy “captions” appear as a page of thumbnails with read more links that display ONLY the articles title.

THEN,   we realized we wanted to have the update articles display only introductory text with read more links, but really needed the words “read more”  for it to make sense.

I was already using html overrides from beez template, and modified the php:   content/category/blog_item.php to include this:

(Note:   section id 3 is the photo gallery, where we don’t want the words “read more” )

item->params->get(’show_readmore’) && $this->item->readmore && ($this->item->sectionid == 3)) : ?>

item->readmore_link; ?>” class=”readonitem->params->get(‘pageclass_sfx’); ?>”>
item->readmore_register) :
echo JText::_(‘Register to read more…’);
elseif ($readmore = $this->item->params->get(‘readmore’)) :
echo $readmore;
else :
echo JText::sprintf($this->item->title);
endif; ?>

 

item->params->get(’show_readmore’) && $this->item->readmore && ($this->item->sectionid != 3)) : ?>

item->readmore_link; ?>” class=”readonitem->params->get(‘pageclass_sfx’); ?>”>
item->readmore_register) :
echo JText::_(‘Register to read more…’);
elseif ($readmore = $this->item->params->get(‘readmore’)) :
echo $readmore;
else :
echo JText::sprintf(‘Read more: ‘,$this->item->title);
endif; ?>

 

On the Guilford Church site, I noticed that the icon to close the lightbox window was missing.  The Web Developer’s Toolbar showed me that that and the “loading” image were trying to load from  a content item/plugin/….path.

I had to open up the lightbox.js and  add ../../ to the front of the image path.

The problem was that the pages with the Simple Image Galleries were at various levels in the site, (with Joomla! built in SEF).

Actually, this solution was first used to tame a “Custom Properties” Tag Cloud.

The site was for negreenhouseupdate.info and we wanted to display the topical tags but not the month and year tags. First I sorted the months and years to the end of the list by adding x or y to the tag name (The tag cloud sorts alphabetically.) Then I added a css rule to hide them:

ul.cpcloud li+li+li+li+li a {display:none;}

The number of “li”s was one more than the number of topical tags in use.

On another site for UMass, Beth wanted to hide a couple of links in a Jooma sub-menu (because they would appear in separate modules, but needed to be part of the sub menu so that the rest of the sub menu would still display.) We sorted the two links to the TOP of the menu. Assigned a class to the menu and then hid all li’s and then displayed all but the first two:

ul.class li {display:none;}
ul.class li+li+li {display:block;}

In the first case, if IE6 doesn’t support the adjacent selector, the worst that will happen will be that IE6 users will see the extra tags listed.

In the second case, the entire menu would remain hidden, so we’ll need an IE6 only rule to display all of the links.
