Is it possible to have different item layouts based on the item's Collection? I imagine you can just create a specialized item show page. Can you write a if-then type statement to determine which show page displays? If so, where does it go?
I have collections with very different types of material: images, video, and links to newspaper databases. I'm using a modified Rhythm theme.
Thanks.
You can do the kind of switching you describe, if you want to. A simple example (for the show page):
$collectionName = collection('Name');
if($collectionName == 'Things') {
// Things layout (or include a whole script) here
} else if ($collectionName == 'Stuff') {
// Stuff layout/include here
} else {
// Layout for items from other or no collection.
}Thanks. Can you walk me through a bit more. I inserted the code at the top of the page like so:
<?php head(array('title' => item('Dublin Core', 'Title'),'bodyid'=>'items','bodyclass' => 'show')); ?>
$collectionName = collection('Name');
if($collectionName == 'Media Reports and Commentary') {
<div id="primary">
<h5><?php echo item('Dublin Core', 'Title'); ?></h5> [with 3 layouts specified]
But I just get all three layouts regardless of the collection. I assume I'm making a simple mistake in coding, but I'm a novice.
Thanks!
You need to enclose PHP code like what I posted in <?php and ?> tags. The confusion is partly my fault, the example I posted isn't quite like what you'd normally see in an Omeka view script. This should be a little better:
<?php $collectionName = collection('Name');
if ($collectionName == 'Things'): ?>
// Things layout (or include a whole script) here
<?php elseif ($collectionName == 'Stuff'): ?>
// Stuff layout/include here
<?php else: ?>
// Layout for items from other or no collection.
<?php endif; ?>Okay, now I just get one layout without errors, but I'm not getting the collection specific layouts. Where does the code you gave me go?
Here's how I'm starting the page:
<?php head(array('title' => item('Dublin Core', 'Title'),'bodyid'=>'items','bodyclass' => 'show')); ?>
<?php $collectionName = collection('Name');
if ($collectionName == 'Media Reports and Commentary'): ?>
<div id="primary">
<h5><?php echo item('Dublin Core', 'Title'); ?></h5>
Try replacing the collection('Name'); part with this:
collection('Name', get_collection_for_item());This is my code:
<?php $collection('Name', get_collection_for_item());
if ($collectionName == 'Media Reports and Commentary'): ?>
Result: Fatal error. Maybe this can't work?
I wasn't quite specific enough I guess. That first line needs to be:
$collectionName = collection('Name', get_collection_for_item());Okay, no error. But not picking up the alternate layout either.
higbie, I think it would help if you could paste the text of your entire show.php file. Github gists is a great way to share chunks of code. You could also use Pastebin.
Jeremy and John:
Here's a link to the code:

I can embed it too if you like.
Thanks for your help. I'm probably making a simple error.

For some reason, the code John suggested isn't working. Instead of doing this:
<?php $collectionName = collection('Name', get_collection_for_item());
if ($collectionName == 'Media Reports and Commentary'): ?>Use the item_belongs_to_collection function in your if statements, like this:
<?php if (item_belongs_to_collection('Media Reports and Commentary')): ?>
Your template stuff here.
<?php elseif (item_belongs_to_collection('Oral Histories')): ?>
Your template stuff here.
<?php endif; ?>You don't need to define $collectionName; Just use the name of the collection as the first argument of the item_belongs_to_collection function. More information on that function is in the codex.
At long last, I've returned to this task and it works! Thanks a million.
One last follow up. If you have more than two templates, your code doesn't quite work. I got it to work with this:
<?php if (item_belongs_to_collection('Media Reports and Commentary')): ?>
Your template stuff here.
<?php elseif (item_belongs_to_collection('Oral Histories')): ?>
Your template stuff here.
<?php else: ?>
default (or last) template stuff hereThere is no "endif" statement.
I don't know if that's "right," but it works for now.
Even when adding the else:, if statements like this should always have an endif; at the end.
Is there an easier way to include sub-templates or snippets instead of writing out the whole template in one file?
So could you do something like..
<?php if (item_belongs_to_collection('Media Reports and Commentary')): ?>
<?php SOME CODE TO LOAD AN EXTERNAL Media Reports SUBTEMPLATE ?>
<?php elseif (item_belongs_to_collection('Oral Histories')): ?>
<?php SOME CODE TO LOAD AN EXTERNAL Oral Historie SUBTEMPLATE ?>
<?php else: ?>
<?php SOME CODE TO LOAD AN EXTERNAL default SUBTEMPLATE ?>
<?php endif; ?>
Sure. Omeka has a function called common() that loads another PHP file from within your theme, or you could use PHP's built-in include directive.
