Bisa jadi inputnya kosong (ga ada nilai) gan.

'.$myinput.'

Itu query kan lebih dari 1 jadi cari query mana yg menyebabkan error. (tutup/comment query yg lain dulu lalu trace satu persatu)

misalkan query anda

 UPDATE tablename SET total = '.$total.'  WHERE

untuk memastikan $total ada nilai, bukan kosong sebab kalau kosong akan menjadi

 UPDATE tablename SET total = ''  WHERE

sisipkan var_dump sebelum query tersebut


var_dump($total);
die();
UPDATE tablename SET total = '.$total.'  WHERE
