mxitid =

_SERVER [ HTTP_X_MXIT_USERID_R];

我要导入的我的数据库通过

sql = INSERT INTO。

Hi Im having some trouble implementing info into a database

I got the line

$mxitid = $_SERVER["HTTP_X_MXIT_USERID_R"];

Which I'm importing to my database via

$sql = "INSERT INTO ".$dbTable." (StringyChat_ip,StringyChat_name,StringyChat_message,StringyChat_time,mxit_id) VALUES (\"$ip\",\"$name\",\"$message\",$post_time,$mxitid)";
                  $result = mysql_query($sql);

well its working perfectly, but the problem I'm experiencing is that if my value

$_SERVER["HTTP_X_MXIT_USERID_R"]

cannot be retrieved I can't insert any info to my database.

the

$_SERVER["HTTP_X_MXIT_USERID_R"]

is being used via a specific platform called mxit, so if I use any other platform it don't work. Is there maybe a way to change the line

$mxitid = $_SERVER["HTTP_X_MXIT_USERID_R"];

to a function if the info couldn't be retrieved to insert another default value like ADMIN rather in the place of it?

mxitid =

_SERVER["HTTP_X_MXIT_USERID_R"];

Which I'm importing to my database via

sql = "INSERT INTO ".
