Use Of Override System

[trickobrien]

hello

just getting to grips with Zen and have noticed the override system

I have edited certain files when defining for example the text displayed on the visitors cart/members cart popup and a lot of other similar edits-without using the override system

does this mean I will have problems for future upgrades?

the only edits I have done are related to wording displayed,and not to functionality

thanks in advance for any advice

Yes. The next time you upgrade, you'll clobber all your changes.

To prevent this, create overrides folders and start moving your changes into there.
(e.g. includes/languages/english/YOUR_TEMPLATE and so forth.)

ok so to move all those into override folders means i am left with original files which have still been edited-should i upload files which havent been edited by me? to replace those?

and also when you say clobbered on upgrade-do you mean script wont upgrade,or i would just lose what i have edited?

Let's say you edited

includes/languages/english/shopping.cart.php

without using the overrides system. Then in the next version, this file gets upgraded. If you just upload all the files which were changed in the new version, you will overwrite your changes and lose them.

To prevent this, create a directory using the name of your template (let's say it's YOUR_TEMPLATE):

includes/languages/english/YOUR_TEMPLATE

then copy

includes/languages/english/shopping.cart.php
to
includes/languages/english/YOUR_TEMPLATE/shopping.cart.php

For completeness, yes, restore the original
includes/languages/english/shopping.cart.php

from a fresh download. That way, if this file changes in a future release, you can just compare the copy you have with the new copy and apply these changes to

includes/languages/english/YOUR_TEMPLATE/shopping.cart.php

Ok,makes sense to do it,I see now that this system allows for customization,without coding yourself out of future upgrades

thanks for your help swguy
