CodeIgniter购物车类阿拉伯语regex [英] CodeIgniter cart class Arabic regex

问题描述

系统/库下的Cart.php有一个正则表达式模式定义，不能使用阿拉伯语作为名称值。这个工作原理：

The Cart.php under system/library has a regex pattern definition that is not enabling me to use Arabic for name values. This works:

$data = array(
  'id' => "221212",
  'qty' => 1,
  'price' => 21.2,
  'name' => 'dasdasdas'
);

但是由于名称中有阿拉伯语，所以失败：

But this fails because of Arabic in the name:

$data = array(
  'id' => "221212",
  'qty' => 1,
  'price' => 21.2,
  'name' => 'عمر'
);

现在在Cart.php类中，我发现了以下内容：

Now in the Cart.php class, I found the following:

// These are the regular expression rules that we use to validate the product ID and product name
  var $product_id_rules = '\.a-z0-9_-';
  // alpha-numeric, dashes, underscores, or periods
  var $product_name_rules = '\.\:\-_a-z0-9';
  // alphanumeric, dashes, underscores, colons or periods

规则。显然这是问题，因为稍后有一个检查：

I am concerned with the name rules. Clearly this is the problem because later on there is a check:

if ( ! preg_match("/^[".$this->product_name_rules."]+$/i", $items['name'])) {
  log_message('error', 'An invalid name was submitted as the product name: '.$items['name'].' The name can only contain alpha-numeric characters, dashes, underscores, colons, and spaces');
  return FALSE;
}

如何替换名称规则字符串以使用阿拉伯语？我有一个很差的背景与正则表达式，所以请帮助。

How can I replace the name rules string to work with Arabic? I have a very poor background with regex, so please help out.

谢谢！

推荐答案

将 product_name regex更改为以下选项：

Change product_name regex to the following, which allows all:

var $product_name_rules = '^.'
