codeigniter key

Opening the source code of the ci framework, it is not difficult to find that there is such a function in the core input class of ci:

Copy the code The code is as follows:

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

{ $ Str = $ this- & gt; UNI-& GT; Clean_string ($ str) (🎜>}


🎜>}
, so an error is thrown

We can rewrite this method in the core of the application
Name it MY_Input.php (the prefix MY_ can be customized in config.php), and then add the following code

Copy code

The code is as follows:

class AI_Input extends CI_Input { //Constructor
function __construct( ){
parent ::__construct();
}

function _clean_input_keys($str)
{
if(preg_match("/^,_[a-z0-9 :_/-]+$/",$str)){
                $str = preg_replace("/,_/","",$str); preg_match("/^[a-z0-9:_/-]+$/i", $str))
                                                                                                                                                     
       return $str;
    }
}

How to solve the problem of batch deletion of key values ​​in redis How to solve the problem of batch deletion of key values ​​in redis May 31, 2023 am 08:59 AM
