next and previous links

Hi
i am trying to make this code below to work
at least i do get a right pagination, going away and coming back with the
links, but no data is displayed

the browser says this lines has a wrong count parameter

while ($dados =3D pg_fetch_array($limite)) {

this line is followed by these
$nome =3D $dados["nome"];
echo "Nome: $nome
";
}

thank?s in advance !
$conn =3D pg_connect("dbname=3Danyname user=3Danyuser");
$busca =3D "SELECT nome FROM aprovados order by nome asc";
$total_reg =3D "20"; // n=FAmero de registros por p=E1gina

if (!$pagina) {
$pc =3D "1";
} else {
$pc =3D $pagina;
}

$inicio =3D $pc - 1;
$inicio =3D $inicio * $total_reg;

$limite =3D pg_exec("$busca LIMIT $inicio,$total_reg");
$todos =3D pg_exec("$busca");

$tr =3D pg_numrows($todos); // verifica o n=FAmero total de registros
$tp =3D $tr / $total_reg; // verifica o n=FAmero total de p=E1ginas

while ($dados =3D pg_fetch_array($limite)) { // vamos criar a visualiza=E7=
=E3o

$nome =3D $dados["nome"];
echo "Nome: $nome
";
}

$anterior =3D $pc -1; // agora vamos criar os bot=F5es "Anterior e pr=F3xim=
o"
$proximo =3D $pc +1;
if ($pc>1) {
echo " ";
}
echo "|";
if ($pc<$tp) {
echo " ";
}
?>

Re: next and previous links

My obvious first question is whether $limite is getting a value. If
not, it'll think no parameters are being passed.

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)
