- Maintaining mvc pattern
- User's browser ip automatically taken when submiting the form
- Encryption receipt id with proper salt and using sha-512
- taking local time zone at entry time
- Back end validation
- Front end validation
- Form submission with ajax and php (for php form submission you need some edition in the code)
- Preventing users from multiple submissions within 24 hours using cookie
- Including search opton with entry_by, from date and to date
- Integrating the ajax response with resetting the form value

1. Create a MySQL DB table with the following requirements and a frontend submission form for storing the data. The - field/Column list are:

   • id (bigint 20) ai
   • amount (int 10) *
   • buyer (varchar 255) *
   • receipt_id (varchar 20) *
   • items (varchar 255) *
   • buyer_email (varchar 50) *
   • buyer_ip (varchar 20)
   • note (text) *
   • city (varchar 20) *
   • phone (varchar 20) *
   • hash_key (varchar 255)
   • entry_at (date)
   • entry_by (init 10) *
2. • marked columns can be submitted through the mentioned frontend form.

3. Buyer_ip should be the user’s browser ip and will be automatically filled up from backend.

4. Hash_key is the encrypted string of ‘receipt_id’ and a proper ‘salt’ using sha-512.

5. Entry_at is the submission date in local timezone.

6. There will be two types of validation process according to the following requirements: A) frontend validation (with js entirely), B) backend validation.

   • Amount: only numbers.
   • Buyer: only text, spaces and numbers, not more than 20 characters.
   • Receipt_id: only text.
   • Items: only text, user should be able to add multiple items (use js based interface).
   • Buyer_email: only emails.
   • Note: anything, not more than 30 words, and can be input unicode characters too.
   • City: only text and spaces.
   • Phone: only numbers, and 880 will be automatically prepended via js in an appropriate manner.
   • Entry_by: only numbers.

7. The submission must be handled by jquery ajax.

8. Using cookie, prevent users from multiple submissions within 24 hours.

9. Create a simple report page where users can see all the submissions and filter it by date range and/ or user id.
