Extend Form_Validation - lucavalentino - 04-04-2016
I use Codeigniter 3.0.6
I want extend the library Form_Validation but not received a personal message error
MY_validation extends CI_Form_validation
PHP Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class MY_validation extends CI_Form_validation {
function MY_validation(){
parent::__construct();
}
function url($str){
$pattern = "|^http(s)?://[a-z0-9-]+(.[a-z0-9-]+)*(:[0-9]+)?(/.*)?$|i";
if (!preg_match($pattern, $str)){
$this->My_validation->set_message('url', 'The URL you entered is not correctly formatted.');
return FALSE;
}
return TRUE;
}
}
My controller
PHP Code:
class valid extends MY_Controller{
public function __construct(){
parent::__construct();
$this->_CI =& get_instance();
$this->_CI->lang->load('upload');
$this->load->model('upload_m');
}
public function index(){
$this->load->helper(array('form', 'url'));
$this->load->library('form_validation','My_validation');
$this->validation->CI =& $this;
......
......
$this->form_validation->set_rules('sito', 'Sito', 'url');
if ($this->form_validation->run()==FALSE){
$this->load->view('upload_edit_view); }
}
}
In the View print an errors echo validation_errors(); see {url} and not personal message.
Help me
RE: Extend Form_Validation - Tpojka - 04-04-2016
You should use visibility attribute in parent class.
Since version 5.3.3 (which is some 6 years now), method with same name as class are replaced with __construct().
Class names in CI3 should be ucfirst treated.
You should make it in way docs propose `MY_Form_validation extends CI_Form_validation{}`.
Prefix `MY_` shouldn't be used when file is called/class is loaded.
`$this->My_validation->set_message` can be `$this->form_validation->set_message`.
RE: Extend Form_Validation - InsiteFX - 04-04-2016
It should also be named MY_Form_validation not MY_validation.
RE: Extend Form_Validation - lucavalentino - 04-04-2016
I changed the library as suggested and etc.
PHP Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class MY_Form_validation extends CI_Form_validation {
protected $CI;
function __construct() {
parent::__construct();
$CI =& get_instance();
}
function url($str){
$pattern = "|^http(s)?://[a-z0-9-]+(.[a-z0-9-]+)*(:[0-9]+)?(/.*)?$|i";
if (!preg_match($pattern, $str)){
$CI->form_validation->set_message('url', 'The URL you entered is not correctly formatted.');
return FALSE;
}
else {
return TRUE;
}
}
}
The library still do not work.
Help me, I can not continue create the application
RE: Extend Form_Validation - Tpojka - 04-04-2016
You don't need to create separate variable for CI instance if you are extending CI system class.
Socondly, when loading your newly created class, you don't need prefix 'MY_'.
PHP Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class MY_Form_validation extends CI_Form_validation
{
public function __construct()
{
parent::__construct();
}
public function url($str)
{
$pattern = "|^http(s)?://[a-z0-9-]+(.[a-z0-9-]+)*(:[0-9]+)?(/.*)?$|i";
if (!preg_match($pattern, $str))
{
$this->form_validation->set_message('url', 'The URL you entered is not correctly formatted.');
return FALSE;
}
else
{
return TRUE;
}
}
}
Controller example code:
PHP Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class Example_c extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->library('form_validation');
}
public function index()
{
//echo 'Example';
}
}

}
public function index()
{
//echo 'Example';
}
}
I believe that the controller does not read extensive library, but only the message from the language file
RE: Extend Form_Validation - Tpojka - 04-05-2016
What I showed you is basic example from docs.
You should test most simplified example like one in docs and see what (and if) went wrong.
I already linked that page/section before.
RE: Extend Form_Validation - InsiteFX - 04-05-2016
PHP Code:
$this->CI =& get_instance();

(04-05-2016, 05:52 AM)InsiteFX Wrote:PHP Code:$this->CI =& get_instance();
I try :
PHP Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class MY_Form_validatio extends CI_Form_validation
{
public function __construct($config = array())
{
parent::__construct($config);
$this->_CI =& get_instance();
}
public function url_formato($str)
{
$pattern = "|^http(s)?://[a-z0-9-]+(.[a-z0-9-]+)*(:[0-9]+)?(/.*)?$|i";
if (!preg_match($pattern, $str))
{
$this->_CI->form_validation->set_message('url_formato', 'The URL you entered is not correctly formatted.');
return FALSE;
}
else
{
return TRUE;
}
}
}
Now to continue the application I using callback function.
RE: Extend Form_Validation - InsiteFX - 04-05-2016
PHP Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class MY_Form_validatio extends CI_Form_validation
should be:
class MY_Form_validation extends CI_Form_validation
{
private $_CI;
public function __construct($config = array())
{
parent::__construct($config);
$this->_CI =& get_instance();
}
public function url_formato($str)
{
$pattern = "|^http(s)?://[a-z0-9-]+(.[a-z0-9-]+)*(:[0-9]+)?(/.*)?$|i";
if (!preg_match($pattern, $str))
{
$this->_CI->form_validation->set_message('url_formato', 'The URL you entered is not correctly formatted.');
return FALSE;
}
else
{
return TRUE;
}
}
}
