you need to lean html forms and php form handler

Before insert value you should post this form. You cannot save value without it.

as urtrivedi and aleksenator said you have to have your options in a <form></form> and need a save button in order to save the data into database. also seeing as your new to php u need a connection to ur database. just to add INSERT into tbl_domain set domain_name=".$myoption." it should be
' ".$myoption." ' also i dont think u really need the mysql_insert_id() you could just add '' into ur query but make sure its in the order of the columns in ut database table example:

table1
|id|name|age|

INSERT INTO tablename VALUES('',$name,$age)

but i guess since this post has been a month ago u should know about this right now.
