Question

I want to make the for loop to return a single value (TRUE/FALSE). But the code returns multiple value. Like TRUETRUETRUE. I understand the code but didn’t have any idea to do it.

public function user_activation_check(){
    for($i=1;$i<5;$i++){
        $query = $this->db->query("SELECT group_info.member".$i." FROM `group_info` INNER JOIN `user_student` ON group_info.member$i=user_student.email WHERE user_student.email=group_info.member$i");
        if($query->num_rows()==1){
            //return TRUE;
            echo"true";
        }else {
            //return FALSE;
            echo"false";
        }
    }
}

Help please.

UPDATE:

public function member_activation(){
    if($this->model_users->user_activation_check()){
        $this->load->view('v_confirm_group');
    }else echo "Some members didn't activate their account.";
}

I think this is what you want:

public function user_activation_check(){
   for($i=1;$i<5;$i++){
        $query = $this->db->query("SELECT group_info.member".$i." FROM `group_info` INNER JOIN `user_student` ON group_info.member$i=user_student.email WHERE user_student.email=group_info.member$i");
        if($query->num_rows()==1){
            // do nothing
        }else {
            echo "false"; // *atleast* one member didn't.
            return FALSE;
        }
    }
    echo "true";
    return TRUE;
}
