PHP MySql PDO Multiple insert doesn't work - php

Question

I have this code for a multiple insert query (I have to transfer data from db to another and makes some update, so I wanna use a code that could do all this automatically)
$query = "select * from pubblicate order by idPubblicate asc";
$dbh = newPdo2();
$dbh->exec("set names utf8");
$sth = $dbh->prepare($query);
$sth->execute();
$count = 0;
$query2 = "insert into published_offer
(codice_onshop,nome,inbreve,anteprima,
galleria1,galleria2,galleria3,galleria4,prezzo,
tp_prezzo,bonus_usabile,proposta,condizioni,
prenotare,categoria,description,keywords,
valido_da,valido_a) ";
while($offerta = $sth->fetch(PDO::FETCH_ASSOC)) {
$array[$count]['id'] = $offerta['idPubblicate'];
$array[$count]['co'] = $offerta['codiceOfferta'];
$array[$count]['no'] = $offerta['nomeOfferta'];
$array[$count]['ib'] = $offerta['inBreve'];
$array[$count]['ke'] = $offerta['keywords'];
$array[$count]['de'] = $offerta['description'];
$array[$count]['pr'] = $pfferta['prezzo'];
$array[$count]['pe'] = $offerta['persona'];
$array[$count]['da'] = $offerta['daTimer'];
$array[$count]['a'] = $offerta['aTimer'];
$array[$count]['an'] = $offerta['anteprima'];
$array[$count]['g1'] = $offerta['galleria1'];
$array[$count]['g2'] = $offerta['galleria2'];
$array[$count]['g3'] = $offerta['galleria3'];
$array[$count]['g4'] = $offerta['galleria4'];
$array[$count]['pro'] = $offerta['proposta'];
$array[$count]['con'] = $offerta['condizioni'];
$array[$count]['pre'] = $offerta['prenotare'];
$array[$count]['bo'] = 999;
if($offerta['italia']=="Sì") $array[$count]['ca'] = "ita";
else if($offerta['europa']=="Sì") $array[$count]['ca'] = "eur";
else if($offerta['mondo']=="Sì") $array[$count]['ca'] = "mon";
$count++;
}
$query2 .= "values (:co,:no,:ib,:an,:g1,:g2,
:g3,:g4,:pr,:pe,:bo,:pro,:con,
:pre,:ca,:de,:ke,:da,:a)";
$dbh = newPdo();
$dbh->exec("set names utf8");
$sth = $dbh->prepare($query2);
$i=0;
echo $array[0]['no'] . " " . count($array) . " " . $array[125]['no'] . "<br>" . $query2 . "<br>";
while($i<count($array)) {
$sth->bindParam(":co", $array[$i]['co']);
$sth->bindParam(":no", $array[$i]['no']);
$sth->bindParam(":ib", $array[$i]['ib']);
$sth->bindParam(":an", $array[$i]['an']);
$sth->bindParam(":g1", $array[$i]['g1']);
$sth->bindParam(":g2", $array[$i]['g2']);
$sth->bindParam(":g3", $array[$i]['g3']);
$sth->bindParam(":g4", $array[$i]['g4']);
$sth->bindParam(":pr", $array[$i]['pr']);
$sth->bindParam(":pe", $array[$i]['pe']);
$sth->bindParam(":bo", $array[$i]['bo']);
$sth->bindParam(":pro",$array[$i]['pro']);
$sth->bindParam(":con",$array[$i]['con']);
$sth->bindParam(":pre",$array[$i]['pre']);
$sth->bindParam(":ca", $array[$i]['ca']);
$sth->bindParam(":de", $array[$i]['de']);
$sth->bindParam(":ke", $array[$i]['ke']);
$sth->bindParam(":da", $array[$i]['da']);
$sth->bindParam(":a", $array[$i]['a'] );
$sth->execute();
$i++;
}
But this code doesn't work. I've also tried to use try-catch(PDOException) for $sth->execute() but it doesn't show me anything.
Why?
Who says "this question is a duplicated" doesn't read really the question. Infact the error was a wrong character: $array[$count]['pr'] = $pfferta['prezzo'] would be been $array[$count]['pr'] = $offerta['prezzo']so I couldn't find an answer in another question.

Answer 1

Try adding some simple checks that things actually worked like this
$res = $sth->execute();
if ( ! $res ) {
echo sprintf('ERROR: %d - %s', $sth->errorCode(), $sth->errorInfo() );
}
