Hi all,
after a bloody lot of trial and error, reading dozens of documents, checking modules like legitimategerman, termsandconditions and not getting results i hope somebody’s here to give me an idea. Seems like nobody has questioned or answered something regarding this way of approaching the topic (or i still did not find anything):
.
How am i able to add a simple custom block into checkout.onepage.review without hacking the core?
So far i only saw the solutions
- to add a completely new tab to the checkout (not possible don’t want to blow up the checkout-process)
- the others seem to overwrite the complete functionality of the checkout (eg. termsandconditions – overkill for my problem i’d say)
.
The concrete problem:
In tab “Order-Review”
- add a block containing a line of text and a checkbox
- position after block totals (and block agreements)
- get Value of checkbox after the order has been made

additionally
- don’t interfere with existing code and files
- shall be used in an update-save extension
- should not require manual interference after installing the extension
