I have adapted a Feedburner email-only subscription form to post to phplist following the Custom Subscribe Form page. It detects invalid emails but displays a phplist form instead of posting:
This brings up the standard http://www.company.biz/phplist/index.php?p=subscribe form with the email address in the box. So the subscriber who has just entered (say) 'firstname.lastname@example.org' must press the Please Confirm button to confirm the subscription.
required fields are marked red
Email address * email@example.com
[ Please Confirm]’
Do I need to define ACCESS_CONTROL_ALLOW_ORIGIN in a header to automate the process and where should I put it? Or is there an alternative?
@duncanc. Yes, thanks for the suggestion I tried it again but there is only one subscribe page. As phplist is returning the page I imagine it has decided not to post the data but ask for manual confirmation.
