MySQL: Prepare statement failed - mysql

Question

I have class with function, which prepares SQL statement to put data into database, but there's an error I can not figure it out, why is happening?
public function vnos_narocila($user) //, $hvrsta_narocila, $hlastna_nabava, $hos, $hsm_dn, $hoe, $hartikel1, $hkolicina_artikel1, $hem1, $hartikel2, $hkolicina_artikel2, $hem2, $hartikel3, $hkolicina_artikel3, $hem3, $hartikel4, $hkolicina_artikel4, $hem4, $hartikel5, $hkolicina_artikel5, $hem5, $hartikel6, $hkolicina_artikel6, $hem6, $hartikel7, $hkolicina_artikel7, $hem7, $hartikel8, $hkolicina_artikel8, $hem8, $hartikel9, $hkolicina_artikel9, $hem9, $hartikel10, $hkolicina_artikel10, $hem10, $hprevzemnik, $hopomba, $hzeljen_datum)
{
$sql = "SELECT * FROM nabava ORDER BY id_nabava DESC LIMIT 1"; //pridobitev zaporedne številke v letu
if( !$this->stmt = $this->mysqli->prepare($sql) )
throw new Exception("MySQL Prepare statement failed: ".$this->mysqli->error);
$this->stmt->execute();
$zadnji_zapis = $this->stmt->get_result();
$zadnji_zapis = $zadnji_zapis-> fetch_array();
$leto = date('Y');
if ( !$zadnji_zapis or $zadnji_zapis[leto] != $leto)
$zap_st=1;
else
$zap_st = $zadnji_zapis[zap_st]+1;
$narocilo = "N-".$zap_st."-".$hoe."/".$leto; //kreiranje številke naročila
$sql_vnos = "INSERT INTO nabava (vrsta_narocila, lastna_dobava, os, sm_dn, prevzemnik, opomba, zeljen_datum_dobave, narocilo, uporabnik, datum_vnosa, zap_st, oe, leto) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, NOW(), ?, ?, ? )";
if( !$this->stmt = $this->mysqli->prepare($sql_vnos) )
throw new Exception("MySQL Prepare statement failed: ".$this->mysqli->error);
$this->stmt->bind_param("iiisssisiiii", $hvrsta_narocila, $hlastna_dobava, $hos, $hsm_dn, $hprevzemnik, $hopomba, $hzeljen_datum, $narocilo, $user, $zap_st, $hoe, $leto );
if( $this->stmt->execute() )
return $this->stmt->insert_id;
return $narocilo;
}
Here is the error:

Please help...

Answer 1

There was a mistake in number of columns and number of values passed.
I'm sorry, I should see that.
