Hello<\/p>\n
Today I was try to install and using insert-php plugin in the first time.<\/p>\n
However, I found a problem when I try to put a custom class that I provide into functions.php name ‘Encryption’ and a code was following:<\/p>\n
class Encryption {\n var $skey = 'Key2015'; \/\/ you can change it\n\n public function safe_b64encode($string) {\n\n $data = base64_encode($string);\n $data = str_replace(array('+','\/','='),array('-','_',''),$data);\n return $data;\n }\n\n public function safe_b64decode($string) {\n $data = str_replace(array('-','_'),array('+','\/'),$string);\n $mod4 = strlen($data) % 4;\n if ($mod4) {\n $data .= substr('====', $mod4);\n }\n return base64_decode($data);\n }\n\n public function encode($value){\n\n if(!$value){return false;}\n $text = $value;\n $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB);\n $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);\n $crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $this->skey, $text, MCRYPT_MODE_ECB, $iv);\n return trim($this->safe_b64encode($crypttext));\n }\n\n public function decode($value){\n\n if(!$value){return false;}\n $crypttext = $this->safe_b64decode($value);\n $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB);\n $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);\n $decrypttext = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $this->skey, $crypttext, MCRYPT_MODE_ECB, $iv);\n return strtolower(trim($decrypttext));\n }\n}\n\n$enc = new Encryption();<\/code><\/pre>\nAfter that I want to use $enc function to call encode() in a post. So, I put a php code between [insert_php]…[\/insert_php] like [insert_php]echo $enc->encode(number);[\/insert_php]<\/p>\n
However after I publish and view post. It was error as blank page with no information and I notice it was generate error_log following:<\/p>\n
[12-Mar-2015 16:54:14 UTC] PHP Fatal error: Call to a member function encode() on a non-object in \/home\/…\/wp-content\/plugins\/insert-php\/insert_php.php(47) : eval()’d code on line 1<\/p>\n
Can I solved this problem?<\/p>\n
P.S. class Encryption() working if put directly into any php page such header.php but not working when try to using in a post with [insert_php]…[\/insert_php]<\/p>\n
Thank you<\/p>\n
