就像我的回答here - 你只需要更新MY_Input正则表达式 - > _ clean_input_keys()允许更多的字符(如逃脱JSON或编码的HTML/XML)
只允许 '英语':!preg_match("/^[a-z0-9\:\;\.\,\?\!\@\#\$%\^\*\"\~\'+=\\\ &_\/\.\[\]-\}\{]+$/iu", $str)
让中国汉字:!preg_match("/^[a-z0-9\x{4e00}-\x{9fa5}\:\;\.\,\?\!\@\#\$%\^\*\"\~\'+=\\\ &_\/\.\[\]-\}\{]+$/iu", $str)
我的完整的工作函数如下所示:
public function _clean_input_keys($str) {
// NOTE: \x{4e00}-\x{9fa5} = allow chinese characters
// NOTE: 'i' — case insensitive
// NOTE: 'u' — UTF-8 mode
if (!preg_match("/^[a-z0-9\x{4e00}-\x{9fa5}\:\;\.\,\?\!\@\#\$%\^\*\"\~\'+=\\\ &_\/\.\[\]-\}\{]+$/iu", $str)) {
/**
* Check for Development enviroment - Non-descriptive
* error so show me the string that caused the problem
*/
if (is_env_dev()) {
var_dump($str);
}
exit('Disallowed Key Characters.');
}
// Clean UTF-8 if supported
if (UTF8_ENABLED === TRUE) {
return $this->uni->clean_string($str);
}
return $str;
}
my_helper.php
if (!function_exists('is_env_dev')) {
function is_env_dev() {
return (
defined('ENVIRONMENT') && strtolower(ENVIRONMENT) == 'development' ||
defined('ENVIRONMENT') && strtolower(ENVIRONMENT) == 'testing'
);
}
}
