Hi
Trying to figure out the php api chain to get all contacts with a certain tag. I thought it would be easy but it is defeating me. I can get all contacts or I can get the tag - but can't seem to combine them...
Have perused the forums and the book. Quite a few chaining examples on create - but not so many on get - and especially getting Tags.
Thanks. Help/suggestions would be appreciated.

What I have:
<code>
funtion getContacts($tagName) {
civicrm_initialize();
$params = array(
'version' => 3,
'is_tagset' => '0',
'name' => $tagName
// this chaining doesn't work
//,
//   'api.contact.get' => array(
//      'tag_id'=> ?
//   )
);

$results=civicrm_api("Tag","getsingle", $params);
return $results
</code>

This works
I get contactss returned which have tag 10
$contactParams = array(
'version' => 3,
'tag'=> '10'
);
$contactResults=civicrm_api("Contact","get", $contactParams);

this does not
civicrm_initialize();
$contactParams = array(
       'version' => 3,
'name' => $tag, // from function
'api.contact.get' => array(
'tag'=> '$id' nor '$tag_id'
)
);
error = DB Error: no such field

If you simply use

civicrm_initialize();
$contactParams = array(
       'version' => 3,
   'name' => $tag, // from function
   'api.contact.get' => 1
   )
   );

$contactResults=civicrm_api("Tag","get", $contactParams);

The the tag id from the outer tag get will be based into the inner contact get as 'tag_id'

For more specific control you can use '$value ' per

http://svn.civicrm.org/civicrm/trunk/api/v3/examples/Contact/APIChainedArrayValuesFromSiblingFunction.php

(there are a few examples in that folder that give variants of it)

Thanks!
I had given up and done two calls  but really wanted to try out that new chaining.
So this does work
civicrm_initialize();
$params = array(
  'version' => 3,
  'name' => $tagname, // coming in from function
  'api.contact.get' => array(
     'tag'=> '$value.id'
   )
);
$results=civicrm_api("Tag","get", $params);

The contacts then come from
$tag_id = $results['id'];
$contactResults = $results['values'][$tag_id]['api.contact.get']['values'];

FYI doesn't work with $results=civicrm_api("Tag","getsingle", $params);

Thanks
