Description
The gform_stripe_charge_pre_create filter allows the charge properties to be overridden before the charge is created by the Stripe API. This filter should not be used to override the $charge_meta[‘metadata’] property.
Note: This filter is applicable only to Products and Services feeds.
When “Enable additional payments” is enabled in the Stripe field settings you need to use this filter along with gform_stripe_payment_element_initial_payment_information
Usage
The hook which would run for all Stripe product and service feeds can be used like so:
add_filter( 'gform_stripe_charge_pre_create', 'your_function_name', 10, 5 );
Parameters
- $charge_meta array
The properties for the charge to be created.
- $feed Feed Object
The feed object currently being processed.
- $submission_data Submission Data
Contains the form title, payment amount, setup fee amount, trial amount, line items created using the submitted pricing field values and any discounts from coupons.
- $form Form Object
The Form which is currently being processed.
- $entry Entry Object
The entry from which the subscription was created.
Examples
1. Add the statement_descriptor property
The following example shows how you can add the statement_descriptor property to the charge meta. Please check Stripe’s documentation for requirements.
add_filter( 'gform_stripe_charge_pre_create', 'stripe_charge_pre_create', 10, 5 );
function stripe_charge_pre_create( $charge_meta, $feed, $submission_data, $form, $entry ) {
$charge_meta['statement_descriptor'] = 'STATEMENTDESC';
return $charge_meta;
}
2. Attach payment method to the customer
The following example shows how you can tell Stripe.com to attach the payment method to the customer for forms using the Stripe Card field.
If the Enable additional payment methods setting is not active in the Stripe field, you would need to use it in combination with gform_stripe_customer_id to create the customer object.
// This sets setup_future_usage parameter to off_session to save the payment method.
add_filter( 'gform_stripe_charge_pre_create', function( $charge_meta, $feed, $submission_data, $form, $entry ) {
gf_stripe()->log_debug( __METHOD__ . '(): Adding setup_future_usage for feed ' . rgars( $feed, 'meta/feedName' ) );
$charge_meta['setup_future_usage'] = 'off_session';
return $charge_meta;
}, 10, 5 );
3. Add the description property
The following example shows how you can add the description property to the charge meta.
add_filter( 'gform_stripe_charge_pre_create', function ( $charge_meta, $feed, $submission_data, $form, $entry ) {
if ( empty( $charge_meta['description'] ) ) {
$charge_meta['description'] = gf_stripe()->get_payment_description( $entry, $submission_data, $feed );
}
return $charge_meta;
}, 10, 5 );
