A fieldtype for Expression Engine 2.
VZ Members displays either a dropdown list or a group of checkboxes containing the members in one or more member groups. The allowed member groups can be set on a per-field basis, as can whether the user can select only one or any number of members. When adding a new entry, the user can select a member or members to associate the entry with.
{members_field}
Will output a pipe-delimited list of member ids. You can also use the separator parameter to separate them with something other than a pipe. For instance {members_field separator=', '} would output something like: 1, 4, 5, 8.
{members_field:names}
Will output a list of member screen names with a comma and space between each. You can also use the separator parameter to separate them with anything else. For instance {members_field:names separator=' and '} would output something like: Bob Smith and Jane Doe and Jimmy Jones.
{members_field:is_allowed members="1|4" groups="3"}
Checks if the members selected in this entry are among the members or groups specified in the tag parameters. You can specify member ids and/or group ids and either one can be a pipe-delimited list. With EE 1.6, it can also be used as a tag pair, in which case the content between the tags will only be displayed if the selected members are among those specified in the tag. EE 2 does not, unfortunately, support that syntax so you must use the tag inside a conditional to get the same effect. For example, if you want to show a notice for every weblog entry where a super-admin was selected, use this code in EE 1.6: {members_field:is_allowed groups="1"}Super!{/members_field:is_allowed}. In EE 2, the equivalent would be: {if "{members_field:is_allowed groups="1"}"}Super!{/if}.
{members_field}{id} - {screen_name}{/members_field}
If you need more control over the output, use the tag pair.
orderby="id|username|screen_name|group_id" - The column to use in ordering the output. Default is id.
sort="asc|desc" - Which order to sort in. Default is asc.
backspace="2" - Remove the last x characters from the final iteration.
id - The id of the current member.
username - The login name of the current member.
screen_name - The screen name of the current member.
group_id - The id of the group to which the current member belongs.
count - The number of the current iteration.
total_results - The total number of members selected.
switch="odd|even" - Switch between multiple values each time through the loop.
If you want to find the entries that have had a particular member assigned to them, you can use the search parameter of the Channel Entries tag pair with the \W option, like this:
{exp:channel:entries channel="news" search:member_field="6\W"}
...
{/exp:channel:entries}
In this example, 6 is the ID of the member you are looking for. The \W makes it match on the individual member IDs in the field, so it won't find partial matches (e.g. you don't want 6 to match member ID 16).
