在第138行的C:\ xampp \ htdocs \ c \ application \ models \ usermodel.php中调用boolean上的成员函数num_rows()

public function new_pass(){

    $email = $this->input->post('email');
    $pass1 = $this->input->post('pass1');
    $pass2 = $this->input->post('pass2');

    $result = $this->db->where('email', $email)->update('user',[
        'pass1' => $pass1,
        'pass2' => $pass2,
    ]);

    if ($result->num_rows() == 1) {
        return TRUE;
    }else{
        return FALSE;
    }
}

对于插入和更新查询,我们使用$this->db->affected_rows()

也可以更改您的查询

public function new_pass(){

    $email = $this->input->post('email');
    $pass1 = $this->input->post('pass1');
    $pass2 = $this->input->post('pass2');
    $this->db->set('pass1',$pass1);
    $this->db->set('pass2',$pass2);
    $result = $this->db->where('email', $email);
    $this->db->update('user');

    $afftectedRows = $this->db->affected_rows();
     if ($afftectedRows == 1) {
        return TRUE;
    }else{
        return FALSE;
    }
}
