/**
|
| 60 |
* This function returns a $query object which will be ready to be
|
| 61 |
* used to look into the activity_log table.
|
| 62 |
* To make things sane, there is always a "center of attention" here: a central
|
| 63 |
* "uid". The next couple of flags will specify if the filter will be done
|
| 64 |
* considering $uid the *creator* of the action, or the *target* of the
|
| 65 |
* action.
|
| 66 |
* There can also be a $friendlist_params, which specify which friend management
|
| 67 |
* module is being used, and which parameters to pass it. The right hook
|
| 68 |
* will then hopefully enrich the query so that filtering is added on a
|
| 69 |
* friendship basis.
|
| 70 |
* It's important to remember that this is an *OR* based query. So:
|
| 71 |
* - If none of the parameters are set, then the query will return EVERY
|
| 72 |
* activity line (no filtering)
|
| 73 |
* - If $uid and $search_as_creator are specified, then the query will return
|
| 74 |
* entries where $uid was the creator
|
| 75 |
* - If $uid and $search_as_creator AND $search_as_target are specified, then
|
| 76 |
* the query wil return entries with $uid and creator OR target
|
| 77 |
* - $friendlist_param is _also_ OR'ed - which means that it will _add_ to
|
| 78 |
* the results
|
| 79 |
*
|
| 80 |
* @param
|
| 81 |
* $uid - The "center of attention"
|
| 82 |
* $search_as_creator - If TRUE, entries where $uid was the creator
|
| 83 |
* will be shown
|
| 84 |
* $search_as_target - If true, entries where $uid was the target will
|
| 85 |
* be shown.
|
| 86 |
* $limit - Limit the query to N records
|
| 87 |
* $friendlist_params - An associative array of parameters to be passed to
|
| 88 |
* the hook hook_activity_log_conditions(). For example:
|
| 89 |
* array('module' => 'friendlist_api', 'status' => 'TW_BOTH')
|
| 90 |

|
