To show the example slideshow block you have several options:
The first two options are described here:
Place an example slideshow block in a region of your theme

Place the ddblock_if_example_slideshows: uprightxx slideshow blocks in a Node
Important: It is important to enable the PHP filter in the module page to allow embedded PHP code/snippets to be evaluated.
<?php
$block = module_invoke('views', 'block', 'view','[VIEWS_BLOCK_NAME]');
print $block['content'];
?><?php
$block = module_invoke('views', 'block', 'view','ef50fae2f402df6963bbb6f39927f019');
print $block['content'];
?>Note: You can find the name of the views block when you hover on the configure link in the block administration page.

Hi
I have some problems with this part
-- Choose as input format: PHP code
I can't find the radio button for PHP. how can I enable it?
thanks!
Re: PHP code
You need to enable the PHP filter (core module) - Allows embedded PHP code/snippets to be evaluated.
If you use an additional role besides user 1 to administer the site, the admin role needs permissions to use the filter.
Hope this helps you further, please let me know.
help: can't see the blocks
i follow all the instructions but there is no block showed on the region
i see the content type, and there is no views_ddblock content type there.
for information, i have successfully install this views before and then for a reason i had to reinstall it.
so i remove this views_slideshows module and its example. i also delete all related content and its content-type, thingking that when i reinstall it will shows up again.
i guess i was wrong...
can you help me? what should i do?
Re: help: can't see the blocks
I think best advice is to uninstall the module and reinstall them
Please post an issue in the issue queue of the module.
