Re: Difference between Blocks and templates

In CakePHP 2.1, Blocks are a part of the core, and are used to display content, scripts and css as a part of the layout.

You can start a block by simply writing to it, using any of the available block commands (i.e. $this->start(), $this->assign(), $this->prepend(), $this->append()), although your mileage may vary if you start appending to a block that hasn't been created.

Your example is using trying to use nested elements, rather than blocks.

The strength of blocks is that you can write to them from helpers, layouts, views and elements, and then choose to display the block at a later time the view or layout processing.  

Several helpers could write to a block that is displayed by an element, and element would not need to know about those helpers.  Without blocks, the element would need to know about those helpers to display the content.

Why do we need a block? And where do we define it?

I think templates are flexible, and I use them as partials and "blocks".
Therefore I'm curious about how to use a block.

For example, I could do this (if I'm not wrong):

Views/index.ctp

<?php echo $this->element('someBlock'); ?>

Then in Views/Elements/someBlock.ctp

<div>    //some layout    <?php echo $this->element('someBlockContent'); ?>  </div>

Then finally in Views/Elements/someBlockContent.ctp

<div>      <p>This is someBlockContent's content</p>  </div>

Nested templates works the same as a block?
