Multiply a value on submit

[pmjm1]

Hi,

I need to submit a form to an external site (credit card processor), but which first multiplies a single field by 100 (cents to dollars) when it is submitted.

Is this possible without putting an intermediate step in?

thanks

Hi pmjm1,

 

Please post your code so we can take a look and give a more definite answer.

I don't have any php yet, just the html form, see below.

The field I need to multiply by 100 is the 'eWayTotalAmount', or just add 00 to the value when it is submitted. So far I can't find a solution without having an additional page.

 

<form method="post" action="https://www.eway.com.au/gateway/payment.asp">

<table>  <tr><td><p>Your last name:</p></td><td>  <input type="text" name="ewayCustomerLastName"/></td></tr>

<tr><td><p>Your first name:</p></td><td>  <input type="text"  name="ewayCustomerFirstName"/></td></tr>

<tr><td><p>Your email address:</p></td><td>  <input type="email" name="ewayCustomerEmail" /></td></tr>

<tr><td><p>Donation amount:</td><td>  AUD$ <input type="text" name="ewayTotalAmount" size="7"></p></td></tr></table>

 

        <input type="hidden" name="ewayCustomerID" value="13xxx563" />

<input type="hidden" name="ewayURL" value="http://www.nnn.com.au/register.php" />

 

<br />

<input type="image" name="submit" src="images/donate-off.png" alt="Join Now" width="191" height="69" border="0" id="Image2" onmouseout="MM_swapImgRestore()" onmouseover="MM_swapImage('Image2','','images/donate-on.png',1)">

 

</form>

Hi pmjm1,

 

I think you're going to have to use a Javascript solution to do this.  Unless your payment gateway provides a PHP API or allows cURL submissions.

 

Someone else may have a better solution for this but I think they're your only options.
