This code will allow you to make a text box on your form that automatically duplicates it's input into a second field. For this example, UMstreet is being copied into UMbillstreet. This allows you to use the billing street address to check the AVS result without having to request the billing address twice.

This method can be used for any textbox you would like to use for more than one field. Use the examples below as a template, and simply replace UMstreet with the field you would like to duplicate and UMbillstreet with the field receiving the duplicate.

HTML

Insert the following between <nowiki><head> and </head></nowiki> tags:

<script>

function copyField()

{

var form = document.epayform;

form.UMbillstreet.value=form.UMstreet.value;

form.UMbillzip.value=form.UMzip.value;

}

</script>

Next find the hidden input fields. It should looks like this:

<input type="hidden" name="UMcommand" value="[UMcommand]">

<input type="hidden" name="UMamount" value="[UMamount]">

<input type="hidden" name="UMtax" value="[UMtax]">

<input type="hidden" name="UMinvoice" value="[UMinvoice]">

<input type="hidden" name="UMcustid" value="[UMcustid]">

<input type="hidden" name="UMrecurring" value=“[UMrecurring]">

Add a line for the field you are copying into. it should look like this:

<input type="hidden" name="UMbillstreet" value=“">

If the field you are copying into already has a textbox remove it by deleting the section that looks like this:

<tr>

<td bgcolor="#F0F0F0" width="234" align="right"><font face="Verdana" size="2">Address:</font></td>

 <td bgcolor="#F0F0F0" width="450">

 <input type="text" name="UMbillstreet" size="25" value="[UMbillstreet]"></td>

</tr>

Lastly find the text input box for the field you are copying from:

<tr>

<td bgcolor="#F0F0F0" width="234" align="right"><font face="Verdana" size="2">Card Billing Address:

</font></td>

 <td bgcolor="#F0F0F0" width="450">

 <input type="text" name="UMstreet" size="25" value="[UMstreet]"></td>

</tr>

Add onChange="copyAVS()" to the input tag so it looks like this:

<tr>

 <td bgcolor="#F0F0F0" width="234" align="right"><font face="Verdana" size="2">Address:

</font></td>

 <td bgcolor="#F0F0F0" width="450">

 <input type="text" name="UMstreet" size="25" value="" onChange="copyField()"></td>

</tr>

Once you have saved changes to your payment form, one text box will populate into two fields.
