When I check all the checkboxes (code below) it gives me this error:
当我检查所有复选框（下面的代码）时，它给了我这个错误：

不允许的关键字符
Here's my HTML:
这是我的 HTML：
<label>Stability Control </label><input type="checkbox" class="largercheckbox" name="checkBox[Stability-Control]"></input><br/>
<label>Xenon Headlamps</label><input type="checkbox" class="largercheckbox" name="checkBox[Xenon-Headlamps]"></input><br/>
What's the problem here? I think my config file permits those characters:
这里有什么问题？我认为我的配置文件允许这些字符：
$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-';

The following function found in system/core/Input.phpdisallows the characters.
中发现的以下功能system/core/Input.php不允许使用字符。
function _clean_input_keys($str) {
if ( ! preg_match("/^[a-z0-9:_\/-]+$/i", $str)) ...
This will allow a-z A-Z 0-9 : _ \ / -
这将允许 az AZ 0-9 : _ \ / -
You should extend the Input class by creating a MY_Input.php file in /application/core/and recreate the method and add any characters you wish to allow. See Creating Core System Classesfor an example as to how to achieve this.
您应该通过在其中创建一个 MY_Input.php 文件来扩展 Input 类/application/core/并重新创建该方法并添加您希望允许的任何字符。有关如何实现此目标的示例，请参阅创建核心系统类。
However you should be careful with this as you could open up unnecessary security holes. You are better off rewriting your form so that it passes the existing validation.
但是，您应该小心这一点，因为您可能会打开不必要的安全漏洞。你最好重写你的表单，让它通过现有的验证。
Edit: This articledescribes both the problem and a solution as described above by extending the Input class.
编辑：本文通过扩展 Input 类来描述上述问题和解决方案。

Ok here is my answer
好的，这是我的答案
You have to go first to system/core/Input.php and look for a function called
你必须先去 system/core/Input.php 并寻找一个叫做
_clean_input_keys($str)
I was don't know what is the character that is disallowed here so when you add the $strlike the following
我不知道什么是当你添加了这里，所以不允许的字符$ STR像下面
if ( ! preg_match("/^[a-z0-9:_\/-]+$/i", $str))
{
exit('Disallowed Key Characters.'.$str); // HERE
}
you will get exactly the character that cause the problem mine was ' ) 'so you have to do one of the following remove the disallowed character from the html or permit it like @Ben Swinburne said
您将获得导致我的问题的确切字符是“)”，因此您必须执行以下操作之一从 html 中删除不允许的字符或允许它像@Ben Swinburne 所说的那样
