CiviCRM Community Forums (archive)

Hi all,

I'm trying to work out a nice way to provide users with a membership form if and only if they meet the criteria for being a member, which can be determined by loading an external PHP script which will call another API etc to look up an external database.

So far, I'm considering the following options:
1) use Drupal's civicrm webform module, hack it to evaluate the external script when called, and if successful create a new member
2) evaluate the external script upon login, and for non-members, assign one of two distinct Drupal permission groups depending on what the external script returns
3) as 2) but using a custom field instead of permissions

Does anyone have any suggestions on how to approach this? I'm not entirely sure how I'd use options 2/3 to generate a different page based on the permission/field anyway.. and yes a fee does need to be paid using a CiviCRM payment processor or cheque/EFT

Thanks
