Correction to what I said above:
I know how to make the e-mail field “un-required” globally by commenting out the relevant code. Specifically:
/*
‘give_email’ => array(
‘error_id’ => ‘invalid_email’,
‘error_message’ => __( ‘Please enter a valid email address’, ‘give’ )
),
*/
However, I want the e-mail field to be un-required only for offline donations. I want it to be a required field for online donations.
Can someone please help me or at least guide me in the right direction? 🙂
