Hi.
I am trying to implement a form to process payments in my online shop.
Everything seems to work fine but for an error in the “total” field.
I have tried diverse solutions with no result.
“Total” is “Importe” (It is in Spanish, sorry).
The coding in the form page:
[CODE]
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>
<html xmlns=”http://www.w3.org/1999/xhtml” xml:lang=”en” lang=”en”>

function aceptar(){
/* var a,b,c;
a = document.formulariotpv.Num_operacion.value;
b = document.formulariotpv.Importe.value;
c = “comercio.php?Num_operacion=”;
c = c + a + “&Importe=” + b;
// alert(c);
document.formulariotpv.redirect.value = c;
// alert(document.formulario.redirect.value);
*/
document.formulariotpv.submit();
}
function Aleatorio()
{
var numero = “” + Math.random();
if(numero[1] == “.”)
{
numero = numero.substring(1,numero.length);
}
numero = numero.replace (“.”, “”);
while(numero[0] == “0”)
{
numero = numero.substring(1,numero.length);
}
return(numero)
}
function MM_swapImgRestore() { //v3.0
var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
}
function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf(“#”)!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}
function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf(“?”))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}
function MM_swapImage() { //v3.0
var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}
}

I would appreciate some comment.
Thus, it contains the javascript that generates a random number for “Operation Number” (“Num_operacion”) and a series of fields with the payment options for each product in the shop.
In this case, just one for the example.
<input type=”radio” name=”Service Option” value=”Opcion” onclick=”document.formulario.Importe.value=968;”/>
The value to process: 968 (9,68 euros).
This page gets and processes the data to comercio.php, which is exactly this:

document.forms[0].submit();

This coding, as you see, send the data to [url]https://pgw.ceca.es/cgi-bin/tpv
I have changed the data for security, but they are ok:
$Clave = “xxxxxxxxxxxxxx”;
$MerchantID = “xxxxxxxxxxxxxx”;
$AcquirerBIN = “xxxxxxxxxxxxxx”;
$TerminalID = “xxxxxxxxxxxxxx”;
For some reason, the first page does not process the value (“Importe”).
Or perhaps comercio.php does not receive or process them properly.
I am not sure.
In any case, I am unable to get the total value (“Importe”) processed:
(document.formulario.Importe.value)
Thanks very much for any comment on this.
