Uses the query syntax described in
QuerySearch to get information about meta-data from one specified topic.
- supports formatted access to formfields and other meta-data in topics using the same syntax as is used in
IF
and SEARCH
statements,
- gives access to all meta-data, including that added by extensions,
- supports reporting values using JSON and other standards, simplifying the retrieval of meta-data for REST applications,
- replaces the
FORMFIELD
macro for most applications.
See QuerySearch for more details of how to write queries
Parameters
Parameter |
Description |
"item" |
The meta-data to query |
style |
set the output format (see below) |
rev |
operate on the given version of the current topic. Note that this will only affect simple queries that refer to the current topic, such as form.name . More complex queries that use searches or indirection to refer to other topics always use the latest version of those topics. |
Examples
Get the name of the form in the current topic:
%QUERY{"form.name"}%
Get the value of the 'Firstname' form field in
the current topic:
%QUERY{"fields[name='Firstname'].value"}%
Get the value of the 'Firstname' form field in
the current topic (shorthand version):
%QUERY{"Firstname"}%
Get a list of all the names of attachments on
the topic 'System.DocumentGraphics':
%QUERY{"'System.DocumentGraphics'/attachments.name"}%
Get configuration setting {NameFilter}:
%QUERY{"{NameFilter}"}%
Plain strings (such as field values) are returned
without quotes. Simple arrays of scalars are also returned without quotes, in a comma-separated list (beware of values that contain commas!).
More complex data structures (e.g. arrays of hashes) will only be returned if
style="perl"
or
style="json"
are set - else will return a string containing 'undef'.
You can make the macro generate different output formats using the
style
parameter:
-
style="perl"
- generates values as Perl code strings generated by running through CPAN:Data::Dumper
-
style="json"
- generates values as JSON strings, suitable for reading by browsers.
Only some configuration settings are available via QUERY:
