[FIXED] How to add unique mobile number by using Cakephp 3.x?

Issue

I know for email address, which is given below. so, suggest me for mobile number.

public function buildRules(RulesChecker $rules)
    {
         $rules->add($rules->isUnique(['email']));
        return $rules;
    }

Solution

You can just replicate what you've got for checking the email address is unique for the relevant mobile field. For example, if your field was phone:-

public function buildRules(RulesChecker $rules)
{
    $rules->add($rules->isUnique(['email']));
    $rules->add($rules->isUnique(['phone']));
    return $rules;
}

You can read more on validating unique fields in the official docs.
