JQGridPlugin

jQuery grid widget for Foswiki

jqGrid is an Ajax-enabled JavaScript control that provides solutions for representing and manipulating tabular data on the web. Since the grid is a client-side solution loading data dynamically through Ajax callbacks, it can be integrated with any server-side technology, including PHP, ASP, Java Servlets, JSP, ColdFusion, and Perl. See also the jqgrid wiki for up-to-date documentation.

web	web where to start the query	BASEWEB
form	DataForm definition which describes the columns of the grid
columns	name of columns to display; these are the formfield names as specified in the DataForm definition in the specified form; there is a list of special column names that are remapped to topic properties (see below)	all columns in the DataForm
include	regluar expression columns/formfields must match to be included in the grid model
exclude	regluar expression columns/formfields must NOT match to be included in the grid model
rows	number of rows to display in the grid per page	20
rownumbers	toggle on/off displaying the row number in the first column of the grid	off
rownumwidth	number of pixels to reserve for rownumbers	25

colname_formatter	(per column option) specifies one of the standard formatters of jqgrid to be used for this column	formats cell values as is
colname_formatoptions	(per column option) additional parameters to be passed over to the column formatter; see the docu of the formatter which these are; this is a list of json objects specified as key:value pairs, comma separated.	none
colname_format	(per column option) specifies a template to be used when formatting the a cell of this column; the format string may contain the variables: ${id}: the id of the row, most often the web.topic name ${value}: the value of the current cell ${key}: some custom key as specified in the =colname_formatoptions Furthermore the format string may contain any formatting features of JQueryTmpl
colname_hidden	(per column option) boolean value; if set the column will be hidden	on
id	id of the grid	Any relevant name
connector	connector ID or a topic name; a grid connector is responsible to interact with the jQGrid widget. This can be a topic that jQGrid should use as the target of its ajax requests, or any other registered grid connector. The topic should have a grid section and render an appropriate XML response based on the URL parameters provided by jqGrid (page, sort, columns, etc).	$Foswiki::cfg{JQGridPlugin}{DefaultConnector}
sortable	(per column option) sort column in ascending or descending order	on
loadonce	grid loads data from the server once, all other manipulations are done on the client side	on
multiselect	allows selection of multiple rows in the grid	on
onSelectRow	event handler triggered when a row is selected
onSelectAll	event handler triggered when all rows selected at once
gridComplete	event handler triggered when the grid is loaded

Special columns

Normally, the data and the way it is displayed in a GRID is specified by the DataForm definition the GRID expression points to. However, there's a set of additional properties of a topic that can be displayed in a GRID. These are specified in the columns parameter to %GRID and are mapped to the actual property as follows:

Colname	Data	Displayed
Author, By	author of the last modification	link to author's profile page
Create Author, Creator	author that created the initial revision of the topic	link to author's profile page
Created, Create Date	date when the initial revision was created	standard date format
Form	the name of a DataForm being attached
Image, Photo	formfields of that name	displayed as html <img> tag where the data is used as src link
Modified, Changed	time when the topic has been changed recently	standard date format
Topic	topic name	link to topic
Title, TopicTitle	title of the topic	string
Workflow	workflow state of the topic	string

When FlexFormPlugin is installed, each cell is rendered using %RENDERFORDISPLAY expression.

When ImagePlugin is installed, each Image/Photo cell is rendered using an %IMAGE expression to render thumbnails.

Grid Connectors

JQGridPlugin is shipped with three connectors:

• search - The default connector that uses native Foswiki search.
• dbcache - Works with DBCachePlugin.
• solr - Works with SolrPlugin.

You can also create your own custom grid connectors by adding the class name to the ExternalConnectors configure option. All parameters to %GRID% that end in _connectorparam will be passed along to your grid connector. Custom grid connectors must process the following parameters:

  my $sortColumn = $request->param('sidx') || $columns[0];
  my $sortOrder = $request->param('sord') || 'asc';
  my $rowsPerPage = $request->param('rows') || 10;
  my $curPage = $request->param('page') || 1;

Installation Instructions

You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.

Open configure, and open the "Extensions" section. "Extensions Operation and Maintenance" Tab -> "Install, Update or Remove extensions" Tab. Click the "Search for Extensions" button. Enter part of the extension name or description and press search. Select the desired extension(s) and click install. If an extension is already installed, it will not show up in the search results.

You can also install from the shell by running the extension installer as the web server user: (Be sure to run as the webserver user, not as root!)

cd /path/to/foswiki
perl tools/extension_installer <NameOfExtension> install

If you have any problems, or if the extension isn't available in configure, then you can still install manually from the command-line. See https://foswiki.org/Support/ManuallyInstallingExtensions for more help.
