the creation of this little vqmod took me awhile.
Its for a shop which is selling braceletts. The customer can choose between many different pendants and should be limted to choose only a maximum amount of pendants.
Iam using the checkbox option. The mod creates a new field in the admin option form called "max_option". There you can enter the max amount.
The Checkbox option itself is then added a picture.
Since I used an huge amount of posts from this forum, I like to share it with you AND hear your comments and suggestions. I assume that this code has much potential to be improved.
This is the Script:
Code: Select all
- <modification>
<id>adding pictures to the checkbox option. resizing the picture limiting the max number of options to be checked creating backend field to define max_option per option in options</id>
<version>0.1</version>
<vqmer>1.0.8</vqmer>
