How to make validations from a query to a table? yii2 - yii2

Question

my problem is: I have a form where i have select2 and the user can select from a dropdown list which is populated from a table, so, basically what i want to happen is that when the user tries to select a driver a validation rule will take place which will check if the driver was already registered through the system that day.
I have one idea of how to do it, i have my archive form which registers people that enter in the archive table, it checks wether it exists or not in the drivers table and if not you have to register them, if they exists you proceed to fill out the form, each field in the this archive table has a datecreated column which is the date the field was entered, so basically the last time he came in.
How can i make a rule which calls for this column compares to current day and gives an error if he had already entered that day? The rule should be in drivers model.(My code is confusing that is why i'm clarifying, i'm new to Yii2)

Answer 1

So, the rule is that only one driver_identitynum and DateCreated combination can exist in the archive table.
To validate the driver_identity field for this you can use the native unique validator and specify the attributes that need to be unique together.
The corresponding rule would be:
[['driver_identitynum'], 'unique',
'targetAttribute' => ['driver_identitynum', 'DateCreated'],
],
If this validation is called from another model, then it complicates matters a bit. In addition to the above:
specify the target class
declare a public date variable in the other model
store current date in this field
indicate the this date property should be used as value to check uniqueness of DateCreated
The adjusted rule would be:
[['driver_identitynum'], 'unique',
'targetAttribute' => ['driver_identitynum', 'date' => 'DateCreated'],
'targetClass' => '\app\models\Archive'
],
