in pratica, questo è il form completo:
codice:
<form action="dispatch_print_bs.php" method="get" target="_blank">
    <div class="pull-left" style="margin-right: 20px;">
        <button type="submit" name="coll" class="btn btn-default-black" value="<?php echo $collezione; ?>">
            <span class="glyphicon glyphicon glyphicon-print"></span> Stampa
        </button>
        <input name="pt" type="radio" value="230"> A3
        <input name="pt" type="radio" value="150" checked> A4
    </div>
    <div class="pull-left">
        <input name="qta_tipo" type="radio" value="pz" checked> Pz
        <input name="qta_tipo" type="radio" value="perc"> %
    </div>
    <?php foreach ($query as $a): ?>
        <button type="submit" name="coll" value="<?php echo $collezione; ?>">
            <span class="glyphicon glyphicon glyphicon-print"></span> Stampa
        </button>
        <input type="hidden" name="forn" value="<?php echo $a['bs_fornitore_codice']; ?>">
    <?php endforeach; ?>
</form>
senza dover ripetere ogni volta la parte prima del foreach, come posso passare quei valori??
