Pet’s market provides users available pets with name, breed, age and prices tagged, allowing them to choose and buy their favorite pet. Once a pet is bought by a customer, a ‘sold out’ tag will be marked below the pet’s picture.
The election feature allow users vote for their favorite pet. A table of candidates is provided as well as the total vote count. Each user is only allowed to vote once.
The registration feature is complimentary to the pet’s election feature above, where users can register their candidates to participate in the election. Users are allowed to added candidates multiple times, but the breed of the candidates are limited to the 4 breeds provided. After user register the candidate, the web will redirect to the election page with the newly added candidate.
I transfer this feature from the SendMeEther learning from Web3Basics. Users can donate any amount Ether they have to the pet shop, their account address and balance will also be shown and rendered on the donation page.
I also add a home page with a navigation bar of the 4 new features. Meanwhile, the account address and real-time balance are also added on each page.
