Validate RelationShip Field

Im have a RelationShip Field expression Engine generate a field name like this

<select name=”blogs[data][]”> <option value=”1”>Blog 1</option>

Im need validate if The selected Blog its created only by the Logged in user, because multiple users can read all entries un a relation pre-filled field

how can?

if im use build in Form rule, The validation system its broken because te field send a array, and the validation system dont read array fields.

For example

for example {exp:channel:form channel="News" rules:blogs="enum[20,21]"} return
