I believe this is the problem
Your delete statements are targetted at field that is not a primary key
mysql_query("DELETE FROM `makhalim` WHERE makhcode ='$newsid'") or die(mysql_error()); AND mysql_query("DELETE FROM makhzim WHERE makhcode ='$newsid'") or die(mysql_error());
Since your makhcode is not a primary key, it is maching all the records for that same code.
