CONTEXT: I’ve used the WPForms plugin in Wordpress to create a custom donation form for my client. The client wants to accept donations via PayPal.

PROBLEM: WPForms has a PayPal add-on feature but it costs $200.

QUESTION To avoid paying $200 for the expensive plugin, how can I manually direct/post the WPForm data entered by the user (name, email, address, donation amount, and employment info) to PayPal?

In the example code you’ll see below, we’re first checking the form ID to make sure it matches the form that’s being targeted. Then we’re checking a specific field (by the field ID) to see if it’s empty.

Just remember to change the form ID from 5 to match your form ID and change the '4' to match your field ID.

function wpf_dev_process( $fields, $entry, $form_data ) {

    // Optional, you can limit to specific forms. Below, we restrict output to
    // form #5.
    if ( absint( $form_data['id'] ) !== 5 ) {
        return $fields;
    }

    // check the field ID 4 to see if it's empty and if it is, run the error    
    if(empty($fields[4]['value'])) 
        {
            // Add to global errors. This will stop form entry from being saved to the database.
            // Uncomment the line below if you need to display the error above the form.
            // wpforms()->process->errors[ $form_data['id'] ]['header'] = esc_html__( 'Some error occurred.', 'plugin-domain' );    

            // Check the field ID 4 and show error message at the top of form and under the specific field
               wpforms()->process->errors[ $form_data['id'] ] [ '4' ] = esc_html__( 'Some error occurred.', 'plugin-domain' );

            // Add additional logic (what to do if error is not displayed)
        }
    }
add_action( 'wpforms_process', 'wpf_dev_process', 10, 3 );
