how to update table using api in codeigniter

问题

I'm stuck at updating table row using api in codeigniter, i already have read tutorial from code tutsplus

but there's no spesific to do it, so i tried by myself and got stuck :-(

url request:

http://localhost/work/bnilife/v1/signup/user/post?nopol=a1b2c3d4e5&username=agus&password=kucingtikus&captcha=c12ds

Here's the json respon:

{
"error": "error :-( "
}

My Controller look like this below:

public function user_post()
  {
    date_default_timezone_set('Asia/Jakarta');
    $datestring ="%Y-%m-%d %H:%i:%s";
    $time       =time();
    $datetime   =mdate($datestring, $time);

    $data = array (
            'nopol'   => $this->input->get_post('nopol'),
            'username'   => $this->input->get_post('username'),
            'password'   => sha1($this->input->get_post('password')),
            'created_at' => $datetime,
            'updated_at' => $datetime
    );

    $result = $this->signup_m->signup_insert($data);
    if($result) {
      $this->response($data, 200);
    } else {
      $this->response(array('error' => 'error :-( '),400);
    }
  }

My model:

  public function signup_insert($data) {

  // Query to check whether username already exist or not
  $condition = "nopol=" . "'" . $data['nopol'] . "'" ;
  $this->db->where($condition);
  $this->db->update('user', $data); }

Is there any something wrong or misstype, thank you guys i'm new at this stuff.

回答1:

You can check codeigniter documentation how are working Database methods http://www.codeigniter.com/userguide3/database

public function signup_insert($data) {
  $this->db->where('nopol',$data['nopol']);
  return $this->db->update('user', $data); 
}

In your case you need and return else you can't use the method as $result as it will be equal to NULL..

Check and CI Form Validation library as you don't validate your input data (even escaped) it may generate problems.
And importantly, you should write proper method names: signup_insert should INSERT not UPDATE.

'nopol' => $this->input->get_post('nopol') in this change to 'nopol' => $this->input->get_post('no_polis'),

also $this->db->where($condition) $condition is not defined.

Like @svetlio said, i add some solution if nopol is typo(misstype) or null. it will return false, so i add some code to do it. like this below:

if ($this->db->affected_rows() === 1) {
    return true;
    } else {
    return false;
    }
  }

so it wont be like:

return $this->db->update('user', $data);
