I'm getting the following error when sending when sending json data via ajax using the codeigniter: Disallowed Key Characters. When I send only one object it works without problems, but when I send more than one object it returns the error.
jQuery.post( "http://localhost/endereco",
{informacao1:"dado1", informacao2:"dado2"},
function(data){
alert(data);
}
);
What you can do is create a file MY_Input.php within application / core
<?php
class MY_Input extends CI_Input {
/**
* Clean Keys
*
* This is a helper function. To prevent malicious users
* from trying to exploit keys we make sure that keys are
* only named with alpha-numeric text and a few other items.
*
* Extended to allow:
* - '.' (dot),
* - '[' (open bracket),
* - ']' (close bracket)
*
* @access private
* @param string
* @return string
*/
function _clean_input_keys($str)
{
if ( ! preg_match("/^[a-z0-9:_\/\.\[\]-]+$/i", $str) )
{
exit('Disallowed Key Characters.');
}
// Clean UTF-8 if supported
if (UTF8_ENABLED === TRUE)
{
$str = $this->uni->clean_string($str);
}
return $str;
}
}
