I am developing a site in which user can recharge his prepaid card. So Card will have a handling charge (in magento terms product price) and the amount to be added to his card (This will be the custom field).
On product view page I show the text box to fill the recharge amount. So once he move to add to cart, handling fee and recharge amount to be carried to cart. So I should add a custom field into cart process.
I am referring this blog:
I have below question and can not find answer. Can some one please help me.
- What are the tables involving in this process?
- Will it impact any problems if add a custom field in order process?
- Is it acceptable to add a custom field?
- If yes is there any guidelines to add a new field?
Thanks in advance.
