[Il_Drugo]

prova cosi:

<?php

$query = "SELECT * FROM Correlate WHERE News1 = '$News' OR News2 = '$News'";
$result = mysql_query($query, $db);
$correlate = mysql_num_rows($result);

if ($correlate == 0) 
{
    echo "<center>[b]Non ci sono news simili[/b]</center>";
} 
else 
{
    $i = 0;
    while ($row = mysql_fetch_array($result)) 
    {
        $id1 = $row["ID"];
        $idx[$i] = $id1;
        $n1 = $row["News1"];
        $na[] = $n1;
        $n2 = $row["News2"];
        $nb[] = $n2;
        $i++;
    }
    
    $nanb = array_merge($na, $nb);
    $strnanb = implode(",", $nanb);
    $query2 = "SELECT * FROM News WHERE ID IN($strnanb) AND ID != $News $posticipata ORDER BY Data DESC";
    $result2 = mysql_query($query2, $db);
    
    $i = 0;
    while($row2 = mysql_fetch_array($result2)) 
    {
        $id2 = $row2["ID"];
        $tit = $row2["Titolo"];
        echo "<a href=\"pag.php?Pag=news&News=$id2\" title=\"$tit\">$tit</a>";
        if ($Modalita == "1" || $Modalita == "2") 
        {
            echo "
<a href=\"pag.php?Pag=elimina_correlata&News=$idx[$i]\" style=\"color: red;\">Elimina</a>";
        }
        echo "

        $i++;
    }
