How to check email address or username is valid or exist through same post?

HTML

 <form action="/index" method="post">
             <input name="post" type="text" value="Username or Email" />
             <input name="submit" name="send" value="Submit" />

        {
            $results = $this->db->where('username', $post)
                                ->where('email', $post)
                                ->get('users');

            if($results->num_rows() > 0)
            {
              //The user has an email or username
              echo "valid";
            } else {
              echo "Invalid";
            }
        }

推荐答案

更改第二个 - >其中子句至 - > or_where

public function index($post) 
    {
        $results = $this->db->where('username', $post)
                            ->or_where('email', $post)
                            ->get('users');

        if($results->num_rows() > 0)
        {
          //The user has an email or username
          echo "valid";
        } else {
          echo "Invalid";
        }
    }
