In Drupal 6, it was easy to insert a block into a template with the following code:
$block = module_invoke('views', 'block', 'view', 'block_name');
print $block['content'];
However, using the same instructions in Drupal 7 does not seem to work. I have looked around and cannot find the new method.
Does Drupal 7 have a routine that can allow for programmatically inserting a block into a template or node?
Recently I faced the same issue and I came across a nice solution which describes the solution in drupal as drupal's way.
You can print regions inside any template, but they aren't available out of the box in the node.tpl.php template. To make them available, you'll create a new variable for use in your node.tpl.php template that'll contain all the region content.
Creating new template variables is done by using a preprocess function. In your theme's template.php file, create a function that looks like this:
Then, in your theme's node.tpl.php template, you can render any region by doing the following:
Where sidebar_first is the name of the region you want to render.

This worked for my Drupal 7 , URL: admin/structure/block/manage/addthis/addthis_block/configure NOTE:delta and module name present in the url itself
$addblock = module_invoke('addthis','block_view','addthis_block');
print render($addblock['content']);

D7:
'module_name' = The machine name of the module (i.e. the module's folder name). This is true for core modules too, so for instance 'search', 'user' and 'comment' would all work here.
'block_delta' = The machine name of the block. You can determine what this is by visiting the block administration page and editing the block. The URL for editing a webform block, for instance, would be something like:
Drupal 7: admin/structure/block/manage/webform/client-block-11/configure
In this example, 'webform' is the module's name, 'client-block-11' is the block's delta.
Custom blocks will have module name of 'block' and a number for a delta, which you can also find by editing the block.
