I found validator unique syntax and used it my project.
I used it, it's working fine, it validate unique of size_metric+size_value in sizes table. But i just don't understand few usage of few parameters.
1. sizes: table name 2. size_value: 1st request value checked against field column (size_value) 3. NULL: ???, 4. NULL: ???, 5. size_metric: 2nd column 6. ,'.$request->size_metric: 2nd request value checked against 2nd column (size_metric)
Can somebody explain this validate unique syntax ? especially the 2 null
Can i make unique validation for 3 columns ? i will have a validation for product_id + size + colour
Really appreciate your thoughts guys, thank you.
