CodeIgniter不允许使用关键字符

CodeIgniter给了我一个Disallowed Key Characters错误。我已经将它缩小到表单字段的name属性：name='prod[50-4121.5]'但我不知道该怎么做。

Answer 1

打开libraries/Input.php（system/core/Input.php在CI版本2.0+中）并找到function _clean_input_keys($str){，整个块应如下所示：function _clean_input_keys($str){     if ( ! preg_match("/^[a-z0-9:_\/-]+$/i", $str))     {         exit('Disallowed Key Characters.');     }     return $str;}修改允许新字符的PCRE sot。请注意，缺少的字符是.（点），你应该总是.在正则表达式中转义（点），否则它们将允许任何单个字符。/^[a-z0-9:_\/-\.]+$/i

要将CodeIgniter与jQuery Ajax一起使用，请使用“Object”作为数据而不是Query字符串，如下所示：$.ajax({ &nbsp;&nbsp;&nbsp;&nbsp;url:&nbsp;site_url&nbsp;+&nbsp;"ajax/signup", &nbsp;&nbsp;&nbsp;&nbsp;data:&nbsp;({'email':&nbsp;email,&nbsp;'password':&nbsp;password}),&nbsp;//<---&nbsp;Use&nbsp;Object &nbsp;&nbsp;&nbsp;&nbsp;type:&nbsp;"post", &nbsp;&nbsp;&nbsp;&nbsp;success:&nbsp;function(response,&nbsp;textStatus,&nbsp;jqXHR){ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$('#sign-up').html(response); &nbsp;&nbsp;&nbsp;&nbsp;}, &nbsp;&nbsp;&nbsp;&nbsp;error:&nbsp;function(jqXHR,&nbsp;textStatus,&nbsp;errorThrown){ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;console.log("The&nbsp;following&nbsp;error&nbsp;occured:&nbsp;"+ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;textStatus,&nbsp;errorThrown); &nbsp;&nbsp;&nbsp;&nbsp;}});
