扩展Codeigniter中的表单验证 [英] Extending form validation in Codeigniter
问题描述
我把这个名为'My_Form_validation.php'的类文件放到'application / core'中,我也试过把它放在'application / libraries'中。
在我的控制器中,我正在使用
$ $ $ this-> form_validation-> set_rules('user_postcode','Postcode',' valid_postcode |修剪|所需| xss_clean');
这是My_Form_validation.php中的内容 - 实际的逻辑在这里没有问题,因为我有一对的选项来实际验证邮政编码。我需要帮助的是理解为什么它没有加载或调用!
我的CI版本是
define('CI_VERSION','2.0.2' );
<?php if(!defined('BASEPATH'))exit('No direct script access allowed') ;

因为你扩展了一个CodeIgniter库而不是一个核心组件,所以你希望把它放在 application / libraries
(不是 application /核心
)。
当然,不要忘记加载 Form_validation
在您的控制器代码中的库。
$ $ $ this-> load-> library('form_validation');
其他要检查的内容: 参考资料:
MY_Form_validation.php
加载,而 My_Form_validation.php
不会) li>
MY_Form_validation
扩展 CI_Form_validation
)
I have placed this class file called 'My_Form_validation.php' into 'application/core' and I have also tried placing it in 'application/libraries'.
In my controller I am using
$this->form_validation->set_rules('user_postcode', 'Postcode', 'valid_postcode|trim|required|xss_clean');
This is whats in My_Form_validation.php - the actual logic is not in question here because I have a couple of options to actually validate the postcode. What I need help with is understanding why it is not loading or getting called!
My CI version is define('CI_VERSION', '2.0.2');
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/**
* Form validation for UK Postcodes
*
* Check that its a valid postcode
* @author James Mills <james@koodoocreative.co.uk>
* @version 1.0
* @package FriendsSavingMoney
*/
class MY_Form_validation extends CI_Form_validation
{
function __construct()
{
parent::__construct();
log_message('debug', '*** Hello from MY_Form_validation ***');
}
function valid_postcode($postcode)
{
/**
*
* UK Postcode validation expression from Wikipedia
* http://en.wikipedia.org/wiki/Postcodes_in_the_United_Kingdom
*
* Note: Remember to strtoupper() your postcode before inserting into database!
*
*/
$pattern = "/^(GIR 0AA)|(((A[BL]|B[ABDHLNRSTX]?|C[ABFHMORTVW]|D[ADEGHLNTY]|E[HNX]?|F[KY]|G[LUY]?|H[ADGPRSUX]|I[GMPV]|JE|K[ATWY]|L[ADELNSU]?|M[EKL]?|N[EGNPRW]?|O[LX]|P[AEHLOR]|R[GHM]|S[AEGKLMNOPRSTY]?|T[ADFNQRSW]|UB|W[ADFNRSV]|YO|ZE)[1-9]?[0-9]|((E|N|NW|SE|SW|W)1|EC[1-4]|WC[12])[A-HJKMNPR-Y]|(SW|W)([2-9]|[1-9][0-9])|EC[1-9][0-9]) [0-9][ABD-HJLNP-UW-Z]{2})$/";
if (preg_match($pattern, strtoupper($postcode)))
{
return TRUE;
}
else
{
$this->set_message('valid_postcode', 'Please enter a valid postcode');
return FALSE;
}
}
}
Because you're extending a CodeIgniter library and not a core component, you want to place that in application/libraries
(not application/core
).
And of course, don't forget to load the Form_validation
library within your controller code.
$this->load->library('form_validation');
Other things to check:
- Filename case sensitivity (
MY_Form_validation.php
loads whileMy_Form_validation.php
won't) - Class name case sensitivity (class
MY_Form_validation
extendsCI_Form_validation
)
