   Hi guys,

   I'm portuguese and here in Portugal we have a payment method that is a generated reference to intantly pay anything without need of upload any receipt.

   There are a company that offers this service and gives me the PHP code needed to send the automatic reference.

   What I'm looking for is the files where I should include that PHP and where to add the info in the confirmation e-mail. I must identify the entry ID and the ammount to pay and define them as the variables.
   The code has two functions:

   function format_number($number)
   	{
   		$verifySepDecimal = number_format(99,2);
   
   		$valorTmp = $number;
   
   		$sepDecimal = substr($verifySepDecimal, 2, 1);
   
   		$hasSepDecimal = True;
   
   		$i=(strlen($valorTmp)-1);
   
   		for($i;$i!=0;$i-=1)
   		{
   			if(substr($valorTmp,$i,1)=="." || substr($valorTmp,$i,1)==","){
   				$hasSepDecimal = True;
   				$valorTmp = trim(substr($valorTmp,0,$i))."@".trim(substr($valorTmp,1+$i));
   				break;
   			}
   		}
   
   		if($hasSepDecimal!=True){
   			$valorTmp=number_format($valorTmp,2);
   
   			$i=(strlen($valorTmp)-1);
   
   			for($i;$i!=1;$i--)
   			{
   				if(substr($valorTmp,$i,1)=="." || substr($valorTmp,$i,1)==","){
   					$hasSepDecimal = True;
   					$valorTmp = trim(substr($valorTmp,0,$i))."@".trim(substr($valorTmp,1+$i));
   					break;
   				}
   			}
   		}
   
   		for($i=1;$i!=(strlen($valorTmp)-1);$i++)
   		{
   			if(substr($valorTmp,$i,1)=="." || substr($valorTmp,$i,1)=="," || substr($valorTmp,$i,1)==" "){
   				$valorTmp = trim(substr($valorTmp,0,$i)).trim(substr($valorTmp,1+$i));
   				break;
   			}
   		}
   
   		if (strlen(strstr($valorTmp,'@'))>0){
   			$valorTmp = trim(substr($valorTmp,0,strpos($valorTmp,'@'))).trim($sepDecimal).trim(substr($valorTmp,strpos($valorTmp,'@')+1));
   		}
   
   		return $valorTmp;
   	}

   //and//

   function GenerateMbRef($ent_id, $subent_id, $order_id, $order_value)
   	{
   		$chk_val = 0;
   
   		$order_id ="0000".$order_id;
   
   		if(strlen($ent_id)<5)
   		{
   			echo "Lamentamos mas tem de indicar uma entidade válida";
   			return;
   		}else if(strlen($ent_id)>5){
   			echo "Lamentamos mas tem de indicar uma entidade válida";
   			return;
   		}if(strlen($subent_id)==0){
   			echo "Lamentamos mas tem de indicar uma subentidade válida";
   			return;
   		}
   
   		$order_value= sprintf("%01.2f", $order_value);
   
   		$order_value =  format_number($order_value);
   
   		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>";
   		}
   
   		if(strlen($subent_id)==1){
   			//Apenas sao considerados os 6 caracteres mais a direita do order_id
   			$order_id = substr($order_id, (strlen($order_id) - 6), strlen($order_id));
   			$chk_str = sprintf('%05u%01u%06u%08u', $ent_id, $subent_id, $order_id, round($order_value*100));
   		}else if(strlen($subent_id)==2){
   			//Apenas sao considerados os 5 caracteres mais a direita do order_id
   			$order_id = substr($order_id, (strlen($order_id) - 5), strlen($order_id));
   			$chk_str = sprintf('%05u%02u%05u%08u', $ent_id, $subent_id, $order_id, round($order_value*100));
   		}else {
   			//Apenas sao considerados os 4 caracteres mais a direita do order_id
   			$order_id = substr($order_id, (strlen($order_id) - 4), strlen($order_id));
   			$chk_str = sprintf('%05u%03u%04u%08u', $ent_id, $subent_id, $order_id, round($order_value*100));
   		}
   
   		//cálculo dos check digits
   
   		$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);
   
   		echo "<pre>";
   		echo "\n\n<b>Entidade:    </b>".$ent_id;
   		echo "\n\n<b>Referência:  </b>".substr($chk_str, 5, 3)." ".substr($chk_str, 8, 3)." ".substr($chk_str, 11, 1).$chk_digits;
   		echo "\n\n<b>Valor: &euro;&nbsp;</b>".number_format($order_value, 2,',', ' ');
   		echo "</pre>";
   	}

   $ent_id and $subent_id are given to me by the company. $order_id and $order_value should be entry_id and ammount. and this last echo's should be sent in the confirmation e-mail.

   I'm trully lost in this. sorry any english mistake.

   best regards.
