The following code has been tested with a datepicker field but would work on any field formatted as a date. Place it in your custom plugin or functions.php file.
add_filter('gf_echeck_subscription_pre_create', 'az_change_subscription', 10, 4);
function az_change_subscription($subscription, $submission_data, $feed, $form) {
// change these values to match your form id and field id
$form_id = 22;
$field_id = 10;
if ($form['id'] == $form_id && isset($_POST['input_' . $field_id]) && !empty($_POST['input_' . $field_id])) {
$subscription->startDate = date('Y-m-d', strtotime(sanitize_text_field($_POST['input_' . $field_id])));
}
return $subscription;
}
Yes, you can set your feed up as a subscription.
When setting up your form, you need a way to tell Gravity Forms which feed to process.
This is my recommendation:
- Add a Payment Method radio button to your form with two options: Credit Card, eCheck
- Enable Conditional Logic in your Credit Card and eCheck fields and set your Credit Card field to be conditional upon the Credit Card choice and eCheck upon the eCheck choice (Advanced Tab on your field)
- In your feed settings, enable Conditional Logic and set the condition based upon the customers choice of payment as well
- You need to go through this with both the Credit Card and eCheck fields so that only one feed is processed at a time.
When you activate the echeck plugin, a new field called Anet eCheck will appear in your Gravity Forms edit page under Pricing Fields.
You will add this field to your form to provide a place for customers to enter their check information. Because there are multiple inputs in this field, Gravity Forms will allow you to map the entire field 'block' or each input individually. However, the feed mapping needs you to map the entire field or Full version.
Please make sure the plugin is activated and there are no other Gravity Forms plugins interfering. I've tested my plugin with all the official Gravity Forms payment addons. But there are other third party plugins that don't follow the Gravity Forms API rules and break the flow. Try disabling any third party Gravity Forms plugins and see if the echeck fields reappear. If so, then enable the other plugins one by one until you find the plugin that breaks it. If not, contact me via email and I will help you figure it out or refund your money.
This is the error from Authorize.net. So we know that you are reaching Authorize.net but there is an issue with the credentials you sent. Please make sure you have entered valid credentials in your Forms>Settings>CIM page. That is the main Settings page under Forms - Not the feed settings under each individual form. (I know - it's confusing. But that is how Gravity Forms is set up and it works great once you're set up. :/) Here is an example from the CIM plugin but they all look similar. 
I am getting this error and not sure why....Code: 33 Error: [field name] is required.
Answer:
This indicates you are requiring a field in your Authorize.net account but it isn't mapped and sent with the transaction.
To check this and correct:
- Login to your Merchant Interface at https://account.authorize.net
- Click Settings in the main left side menu
- Click Payment Form
- Click Form Fields
- Uncheck the field provided in the Error 33 text. (optional)
- Click Submit
Make sure you are mapping them in the feed settings and that you have the latest version. There was a bug that was fixed in 1.4.
There is a hook for that:
$transaction = apply_filters('gf_echeck_transaction_pre_capture', $transaction, $submission_data, $form, $entry);
So an example might look like:
add_filter( 'gf_echeck_transaction_pre_capture', 'set_invoice_number_for_echeck', 10, 1 );
function set_invoice_number_for_echeck( $transaction ) {
// You might want to do some other sanitizing or even validate it before sending. This is just cleaned by with rgpost.
$value = rgpost( 'input_2' );
$transaction->setField( 'invoice_num', $value );
return $transaction;
}
