CiviCRM Community Forums (archive)

To export all contacts that meet a particular search criterion (e.g. membership in a particular group) I have to do at least the following:
a) click on Search... > Find Contacts
b) specify my desired search criterion (e.g. the particular group whose members I want to export)
c) click the "Search" button
d) click the "All nnn records" radio button
e) select "Export Contacts" from the pull-down and click on "Go"
f) click on "Select fields for export"
g) select a previously-defined export profile
h) click "continue"
i) click "done"

To do this in multiple similarly-configured sites (same groups etc., but each site has its own different data) I of course have to log in to each site and repeat the above steps for each site.

I am hoping to be able to invoke the CiviCRM export via URL, but my browser reports the URL after step I above to be:
http://my.domain/index2.php?option=com_civicrm&task=civicrm/contact/search&&_qf_Map_display=true&qfKey=32-hex-digits_NNNN -- and of course I don't know what this qfKey decrypts to!

What I was hoping for was something more along the lines of "option=com_civicrm&task=civicrm/contact/search&group=group_name&export=all&profile=profile_name" or some such -- or (better yet) a way to do the export via a PHP script via the back end.

Any ideas?
