Hi,
I have been trying to echo a function result, but I’m a little lost here.
If I don’t call the function it works it prints out the html code (without the function part), but if I call the function, I get a blank screen.
any help?
[php] <?php
function GenerateMbRef($order_id, $order_value)
{
// IMPORTANTE: Coloque aqui o seu codigo de entidade e sub-entidade correctamente
$ent_id = “11202”;
$subent_id = “189”;
$order_id =“0000[INVOICENO]”;
$order_value = trim("[ORDERAMOUNT]" , ‘€’); // only delete € at start or end of the string
// Apenas são considerados os 4 caracteres mais à direita do order_id
$order_id = substr($order_id, (strlen($order_id) - 4), strlen($order_id));
if ($order_value < 1){
echo "Lamentamos mas é impossível gerar uma referência MB para valores inferiores a 1 Euro";
return;
}
if ($order_value >= 1000000){
echo "<b>AVISO:</b> Pagamento fraccionado por exceder o valor limite para pagamentos no sistema Multibanco<br>";
}
while ($order_value >= 1000000){
GenerateMbRef($order_id++, 999999.99);
$order_value -= 999999.99;
}
//cálculo dos check digits
$chk_str = sprintf('%05u%03u%04u%08u',$ent_id, $subent_id, $order_id, round($order_value*100));
$chk_array = array(3, 30, 9, 90, 27, 76, 81, 34, 49, 5, 50, 15, 53, 45, 62,38, 89, 17, 73, 51);
for ($i = 0; $i < 20; $i++)
{
$chk_int = substr($chk_str, 19-$i, 1);
$chk_val += ($chk_int%10)*$chk_array[$i];
}
$chk_val %= 97;
$chk_digits = sprintf('%02u', 98-$chk_val);
$teste .= "<pre>";
$ref1= $subent_id." ".substr($chk_str, 8, 3)." ".substr($chk_str, 11, 1).$chk_digits;
return $ref1;
}
$ent_id = “11202”;
