need Module similer to donate as i described below

I need module like donation but a bit different
This module guide customer directly to checkout page
customer define amount of money
customer describe payment reason in text box

position: like category in right or left--- under category small box like donate module include one button guide to page that include description of payment and boxes to fill ( amount and payment reason ) and proceed to checkout

in admin interface could define page description --min and max of amount --- position of mudule

Indeed in this module there is no product and customer define amount and payment reason and then go to checkout procedure

In admin Extensions / Modules / Welcome / Edit / Insert, and with Source mode toggled on (wysiwyg mode off) just top left of the entry box, put in a PayPal Donate (or similar other) button, position that where you want it (such as top and first in sort order), and while in Source mode Save that. The effect will be going straight to PayPal (in its instance), where there will be a Note box for entering whatever your customers wish to put there, and a box for hand entering a sum of your customers' choice. The return from PayPal (or other) can land normally, as preset in your account there. No muss, fuss, or feathers, they choose to Donate, they wind up straightaway inside PayPal, do it, and wind up back in your website (unless they detour). Try playing with that to see if it does what you have in mind.

Thank you .your idea is simple but Intelligent
A good idea
but this can not solve my problem because we use other payment modules that don't support or don'tact like PayPal.
It can solve a part of problem
I can use it to place button to guide customers to the described page
Now i need the page include : some description , text box to get payment amount , text area to get payment reason
and procedure/button that led to checkout.

This is not donate. consider that customer pay for the services we do. so i need the information to be recorded as a product selling , in my shop invoice and access their payment information.

any help plz....




This means no one do know about opencaet or no one interested in opencart's development
Is this true?

Extensibility to other portals is why I noted "PayPal (in its instance)" and "PayPal (or other)".

PayPal itself now allows both Donate and Buy Now to work the same way, with a Note box and an amount box. What matters is that there's a written even if brief reason, and a tendered sum. Whether the button or box happens to say Donate or Buy Now or Howdy does not matter. Tax outfits world wide just want to know how much you made (legitimately or not) and how much you owe, and whether the almighty tax form as well as the payment are sent in. Tax outfits world wide won't take Donate or Buy Now or Howdy literally, they will look instead at substance -- why and how much.

PayPal has both buttons, PayPal has both boxes for each button. Other portals may have similar buttons. If they do not, then they might not even allow streamlining. The Extensions button top right leads into the store, where there are extensions that deal with all manner of aspects of payment. The initial list spans several pages.

There are scores upon scores of searchable posts and threads dealing with adding text boxes and capturing their content. There is a Search button top right.

Easy, Laddy, this one is right at the wrong edge: "This means no one do know about opencaet or no one interested in opencart's development. Is this true?" That is an open invitation to an array of Moderators and others to vent in concert, as has happened from time to time over such remarks. People are strewn around the world and respond when they can, many people here understand OC fairly well to extremely well, and as for development it is the best shopping cart among both free and commercial carts.
