CodeIgniter禁用键字符 [英] CodeIgniter Disallowed Key Characters

问题描述

CodeIgniter给我一个 Disallowed Key Characters 错误。我把它缩小到一个表单字段的名称属性： name ='prod [50-4121.5]'但我不知道该怎么办。

CodeIgniter is giving me a Disallowed Key Characters error. I've narrowed it down to the name attribute of a form field: name='prod[50-4121.5]' but I'm not sure what to do about it.

推荐答案

打开 libraries / Input.php （ code> function _clean_input_keys（$ str）{，整个块应该看起来像所以：

Open libraries/Input.php (system/core/Input.php in CI version 2.0+) and locate function _clean_input_keys($str){, The whole block should look like so:

function _clean_input_keys($str)
{
    if ( ! preg_match("/^[a-z0-9:_\/-]+$/i", $str))
    {
        exit('Disallowed Key Characters.');
    }

    return $str;
}

修改PCRE sot以允许新的字符。

Modify the PCRE sot that it allows the new chars.

请注意，缺少的字符是。（点），应该总是转义。 / code>（点），因为它们将允许任何单个字符。

Please not that the char thats missing is the .(dot) and you should always escape the .(dot) in Regular Expressions as they will otherwise allow any single char.

/^[a-z0-9:_\/-\.]+$/i
