Sometimes you need to print a block in a template. For example, inside a node.tpl.php file.
It's quite easy. In this example, we are going to print out a disqus comment block.
1. Go to yoursite.com/admin/structure/block
2. Get the url of the block you want to print. Make a note of the bold and italic elements the URL:
yoursite.com/admin/structure/block/manage/disqus/disqus_comments/configure
3. Use the following code in your tpl.php file. You need to insert the elements identified in step 2
<?php
$block = module_invoke('disqus', 'block_view', 'disqus_comments');
print render($block['content']); ?>Your block will now display.
