I recently was part of a team that launched MyCellPhoneTutor.com. The site is a WordPress website and uses the Cart66 shopping cart plugin to handle all of the e-commerce functionality. This wasn’t my first rodeo with Cart66, but it was the first time (for some reason) that I noticed customers were being sent two receipts when they made a purchase. They were being receipted from MyCellPhoneTutor.com as well as from Authorize.net.
I only wanted one receipt to be sent to the customer. In this case I wanted it to come from MyCellPhoneTutor.com and not from Authorize.net. I did a quick search and found my answer. I needed to set the x_email_customer field to false. I couldn’t find any mention of the field in Cart66 user’s guide, nor could I find it mentioned in any of the php files. I later learned that the field was defaulted to true and had to be explicitly set to false to disable the emails. I did a little more scanning of the code and I found this section in the Cart66AuthorizeNet.php file:
<pre>
// some default values
$this->addField(‘x_version’, ’3.1′);
$this->addField(‘x_delim_data’, ‘TRUE’);
$this->addField(‘x_delim_char’, ‘|’);
$this->addField(‘x_url’, ‘FALSE’);
$this->addField(‘x_type’, ‘AUTH_CAPTURE’);
$this->addField(‘x_method’, ‘CC’);
$this->addField(‘x_relay_response’, ‘FALSE’);
</pre>
What you want to do to stop the Authorize.net emails, as you have probably already figured out, is to add this line of code just below the above snippet:
<pre>
$this->addField(‘x_email_customer’, ‘FALSE’);
</pre>
Don’t forget to upload the changes to your server. After you do, the Authorize.net auto-generated emails should stop immediately.
