Laravel 5 Validation unique pass variable placeholder

Question

Is it possible to pass the unique validation method extra where clauses with a variable?

Heres an example:

In my model I have my validation rules.

Answer 1

The Laravel documentation on validation has a sub-section titled, “Adding Additional Where Clauses” in the unique rule section:

You may also specify more conditions that will be added as "where" clauses to the query:

'email' => 'unique:users,email_address,NULL,id,account_id,1'

In the rule above, only rows with an account_id of 1 would be included in the unique check.

Unfortunately you will have to concatenate a variable value if you want it passed as part of the conditions:

'circle_id' => 'required|unique:donations,circle_id,NULL,id,cause_id,'.$causeId,

Or you make it more readable by specifying validation rules as an array:

'circle_id' => [
    'required',
    'unique:donations,circle_id,NULL,id,cause_id,'.$causeId,
],
