Direct price entry attribute?

[dhcernese]

Is there any way to have an attribute allow the direct entry of a monetary value?

Yea, I know, 'let the customers pick their own prices?' No, it's like a "donation".. ..they have to enter an amount and that gets added to the price. I tried pulldowns, but the list is too long and tedious to maintain.

If you do find out, please let me know, I need this too.

This would likely require a new PRODUCTS_OPTIONS_TYPE which are stored in the table of the same name and all the associated code to handle it.

Well, I just recently made a module similar to this, yes you are right dhcernese I added a new PRODUCTS_OPTIONS_TYPE and PRODUCTS_OPTIONS_VALUE

and um... I guess it is slightly better than what you had in mind, I use sliders

Check this out:

But I got one problem though:

This module changed 3 core files, attribute.php and both header_php.php files in checkout_confirmations and shopping_cart pages. I still cannot find a workaround to this, do you think that is fine?

Not sure if it's working?

Try to make an actual donation with it ;)

More experienced Zenners could better comment on the structure of your modifications. However, I believe you cannot make this change without modifying several core files-- and if you do, they should use the override system (perhaps in your template subdirectories!).

I'm surprised it's only 3 files.. ..I started down this path and found myself modifying more. I started by creating custom defines in my own files, to support a type of "monetary".

Going down this path one notices that there are then three exceptions to most of the code, _FILE, _TEXT, and now this new one. Hints at some refactoring required to more directly support a base type that does not come with a set of specified values.

p.s. your slider is interesting. it did not slide in real-time response to my mouse only moved after releasing, however. is it supposed to follow the mouse?

Well I cheated a bit, to tell you the truth, For example for the classes/shopping_cart.php I did actually changed that file but instead of directly changing it there, I made my changes to a new file sliderview_donation_shopping_cart.class.php and pointed Zen-Cart to load that class instead of shopping_cart.php.

One thing I'd like to see Zen-Cart would be able to handle is the ability for developers to add new attribute types. One way to help this is by dividing the includes/modules/attributes.php into several auto-loaded files. But looks like they got more important issues to resolve than this eh?

Exactly, looks like you went to the right direction here.

Ah yes you are right, looks like the changing of bubble talk content caused memory leak in IE, it was perfect in Mozilla, as usual. I have changed that, the content is now changing only after the handler set to a position. Thanks for letting me know.

Hi jaycode, have you released this as a contribution or is it available for purchase somewhere?

I don't need anything fancy like you have with the slider. I actually did want it to let customers choose their price and also to use as a general payment product.

[jaycode]

Hi tj1, yes I plan to make this as a contribution someday later, I just switched to Mootools from Scriptaculous, so I need to re-write all my existing code, which is crazy...

Plus, the exams are coming. At current rate, I think I can start working on it by March, sorry I hope you do not need the module ready soon?

Hi, just checking again to see if you've already made a contribution of this.

Thanks.

Nope I haven't, been very busy to deal with contributions these days. I can give you the module with slider still attached and you can remove them yourself if you want?
