Setting Up Dwolla Payment Method

[phishbed]

I'm anxious to start using Dwolla so I've put together this temporary solution by setting up Dwolla as a payment method under Credit Card Payment with Simple Validation. It's almost working, I appear to be having one simple problem, maybe someone can help me out. I got the idea while recently implementing Sebenza's Gift Certification Module which hides the credit card input fields on OPAY if your order total is $0. Here's my OPAY page code so far. It says, or should say, if the payment method is Dwolla then hide the credit card entry fields and give Dwolla payment instructions.

<form method="post" action="&mvt:payment:url;" onsubmit="return submitOnce()">
<input type="hidden" name="Action" value="AUTH">
<input type="hidden" name="Screen" value="INVC">
<input type="hidden" name="Store_Code" value="&mvte:global:Store_Code;"> 


<mvt:if expr="l.settings:basket:formatted_total NE '($0.00)'"> 


  <mvt:if expr="l.settings:payment:desc EQ 'Dwolla'">


    <input type="hidden" name="PaymentMethod" value="">
    <tr><td align="left" valign="middle">
    <b>Thank you for selecting Dwolla as your payment method! DWOLLA INSTRUCTIONS GO HERE</b>
    </td></tr>


  <mvt:else>


    <mvt:item name="payment" />
  </mvt:if>
</mvt:if>


<table border="0" cellpadding="2" cellspacing="0" width="100%">
<tr><td align="left" valign="middle" bgcolor="&mvt:colors:lhdr_bg;">


<mvt:if expr="l.settings:basket:formatted_total EQ '($0.00)'">
  <input type="hidden" name="PaymentMethod" value="">
  <tr><td align="left" valign="middle">
  <b>Your balance is zero and no payment is necessary. Press continue to complete your purchase.</b>
  </td></tr>


<mvt:else>


  <mvt:if expr="l.settings:payment:desc NE 'Dwolla'">    
    <b>Payment Information:</b>


    <input type="hidden" name="PaymentMethod" value="&mvte:global:PaymentMethod;">


  <mvt:if expr="NOT ISNULL l.settings:payment:desc">


  <b>&mvt:payment:desc;</b><br>


</mvt:if>


<mvt:if expr="NOT ISNULL l.settings:payment:message">


  &mvt:payment:message;<br>


</mvt:if>




<table border="0" cellpadding="2" cellspacing="0">

<mvt:foreach array="payment:fields" iterator="field">
  <tr><td align="left" valign="middle">


  <mvt:if expr="l.settings:field:invalid">
    <font color="red"><b>&mvt:field:prompt;</b></font>
  <mvt:else>
    <b>&mvt:field:prompt;</b>
  </mvt:if>


  </td><td align="left" valign="middle">


  <mvt:item name="payment" param="field:code" />


  </td></tr>
</mvt:foreach>
</table>
</td></tr> 
</mvt:if>
</mvt:if>
</table>


<br>    


<mvt:item name="buttons" param="Continue" />


</form>

I'm getting the following Runtime error. I'm guessing its trying to collect credit card data that was never entered.

Runtime error in mm5/5.00/merchant.mvc @ [0000000e:0000044a]: merchant.mv: Line 1044: MvDO: Unable to open 'mm5/5.00': File is either corrupt or not a valid compiled Miva Script file

Hopefully we can use this as a temporary solution until we get an official Dwolla Payment Module.

Re: Setting Up Dwolla Payment Method

I've tried filling in default values for the Dwolla Simple Validation Payment method and I still get the runtime error.

<mvt:if expr="l.settings:basket:formatted_total NE '($0.00)'">  

  <mvt:if expr="l.settings:payment:desc EQ 'Dwolla'">

<input type="hidden" name="PaymentMethod" value="Dwolla">
<input type="hidden" name="CardName" value="Dwolla">
<input type="hidden" name="CardNumber" value="5555555555555555">
<input type="hidden" name="CardExp_Month" value="05">
<input type="hidden" name="CardExp_Year" value="05">

Re: Setting Up Dwolla Payment Method

I'm pretty sure my input variable names are incorrect. I'm getting this error:

One or more required fields were not filled out correctly.

with this code:

<mvt:if expr="l.settings:basket:formatted_total NE '($0.00)'">  

  <mvt:if expr="l.settings:payment:desc EQ 'Dwolla'">

<input type="hidden" name="PaymentMethod" value="&mvte:global:PaymentMethod;">
<mvt:if expr="NOT ISNULL l.settings:payment:desc">
                    
                    <b>&mvt:payment:desc;</b><br>
                    
                </mvt:if>
<mvt:if expr="NOT ISNULL l.settings:payment:message">
                    
                    &mvt:payment:message;<br>
                    
                </mvt:if>

<input type="hidden" name="payment:CardName" value="Dwolla">
<input type="hidden" name="payment:CardNumber" value="4555555555555555">
<input type="hidden" name="payment:CardExp_Month" value="5">
<input type="hidden" name="payment:CardExp_Year" value="2015">

Re: Setting Up Dwolla Payment Method

I finally solved this problem by purchasing the Phone In Payment Module from Emporium Plus. I just changed the Phone-In text to say Dwolla in the admin settings and it seems to be working perfectly! The checkout and invoice message screen tokens are also a huge help.
