Edit Table Plugin

Edit Table Plugin

This plugin allows you to edit TWiki tables using edit fields and drop down boxes. Tables have an [ Edit table ] button if preceeded by an %EDITTABLE{...}% variable. Each column can be a text field, a drop down box, a date field, etc. Multiple tables per topic are editable, but only one at a time can be edited.

Per Table Settings

Add a %EDITTABLE{...}% variable just before an existing table to make it editable, or add the variable anywhere in a topic to start a new table. Parameters:

Parameter	Comment	Default
header	Specify the header format of a new table like "|*Food*|*Drink*|". Useful to start a table with only a button	(no header)
format	The format of one column when editing the table. A cell can be a text input field, or any of these edit field types: - Text input field (1 line):   | text, <size>, <initial value> | - Textarea input field:   | textarea, <rows>x<columns>, <initial value> | - Drop down box:   | select, <size>, <option 1>, <option 2>, etc | - Fixed label:   | label, 0, <label text> | - Row number:   | row, <offset> | - Date:   | date, <size>, <initial value>, <DHTML date format> |	"text, 16" for all cells
changerows	Rows can be added and removed if "on"; Rows can be added but not removed if "add"	CHANGEROWS Plugin setting
quietsave	Quiet Save button is shown if "on", hidden if "off"	QUIETSAVE Plugin setting
include	Other topic defining the EDITTABLE parameters. The first %EDITTABLE% in the topic is used. This is useful if you have many topics with the same table format and you want to update the format in one place.	(none)
helptopic	Topic name containing help text shown below the table when editing a table. The %STARTINCLUDE% and %STOPINCLUDE% variables can be used in the topic to specify what is shown.	(no help text)
headerislabel	Table header cells are read-only (labels) if "on"; header cells can be edited if "off" or "0"	"on"
editbutton	Set edit button text, e.g. "Edit this table"; set button image with alt text, e.g. "Edit table, %PUBURL%/%TWIKIWEB%/TWikiDocGraphics/edittopic.gif"; hide edit button at the end of the table with "hide" (Note: Button is automatically hidden if an edit button is present in a cell)	EDITBUTTON Plugin setting

Initial Values

By default, variables in <initial value> (of text input field) and <label text> (of fixed label) get expanded when a new row is added. This can be used for example to add a timestamp to a label. You can escape characters if you do not want that:

Text:	To Escape:
$quot	Double quote ("). Alternatively write \" to escape it
$percnt	Percent sign (%)
$dollar	Dollar sign ($)
$nop or $nop()	Is a "no operation"

Date Field Type

The date field type allows one to choose a date with a popup calendar. Popup calendar works for Netscape 6.0 or better, all other Gecko-based browsers, Internet Explorer 5.0 or better for Windows, Opera 7 and Konqueror 3.1.2. The ... button is inactive if the browser cannot support the popup calendar. It uses the nice Mishoo DHTML calendar, see also TWiki:Codev/JavaScriptDatePickerForForm

Per Cell Settings

An individual edit field type can be defined for each table cell. Place an %EDITCELL{ "type, ..." }% variable at the end of the cell content. This is useful to override the per column %EDITTABLE{ format="..." }% settings, or to create tables with key/value rows. All edit field types of the format="..." parameter are supported. For example, to define a text field, type: | cell content %EDITCELL{ "text, 20" }% |

It is also possible to place the edit button inside a cell instead of default location below the table. Type | %EDITCELL{ "editbutton, 1, Edit this table" }% | to show a button, or | %EDITCELL{ "editbutton, 1, Edit table, Image-URL" }% | to show a button image with alternate text.

Note: The %EDITCELL{ }%=variable cannot be used by itself; place an =%EDITTABLE{ }%=variable at the beginning of a table where you want to use =%EDITCELL{ }% variables.

Table Buttons

• In page view mode:
  • - turn the table into edit mode
• In edit mode:
  • - save your changes
  • - save your changes without alerting subscribed WebNotify users
  • - add row to the table (if enabled)
  • - remove last row from the table (if enabled)
  • - cancel without saving and release edit lock

Examples

Line before table: %EDITTABLE{ header="|*Nr*|*Text field sandbox*|*Drop down sandbox*|*Timestamp*|" format="| row, -1 | text, 20, init | select, 1, one, two, three, four | label, 0, %SERVERTIME{"$day $mon $year $hour:$min"}% |" changerows="on" }%

Nr	Text field sandbox	Drop down sandbox	Timestamp
1	hello table	one	26 Jun 2002 12:30
2		two	27 Jun 2002 12:40

If this plugin is installed you will see an [ Edit table ] button above; when you click on it you get this form:

Nr	Text field sandbox	Drop down sandbox	Timestamp
1		one two three four	26 Jun 2002 12:30
2		one two three four	27 Jun 2002 12:40

(demo only, these buttons do not work)

The following example shows a simple table with key/value rows. The default edit field type for the value column is a text field. This is overloaded by a selector for the Gender, and a date picker for the DOB. This is typically used by TWiki applications where new topics with tables are created based on a template topic.

You type: %EDITTABLE{ format="| label | text, 40 |" }% |*Key*|*Value*| | Name: | John Smith | | Gender: | M %EDITCELL{select, 1, , F, M}% | | DOB: | 1999/12/31 %EDITCELL{date, 10}% | | City: | New York |

Plugin Settings

Plugin settings are stored as preferences variables. To reference a plugin setting write %<plugin>_<setting>%, for example, %EDITTABLEPLUGIN_SHORTDESCRIPTION%

• One line description, shown in the TextFormattingRules topic:
  • Set SHORTDESCRIPTION = Edit TWiki tables using edit fields, date pickers and drop down boxes

• Set DEBUG to 1 to get debug messages in data/debug.txt. Default: 0
  • Set DEBUG = 0

• Default for change rows flag: on, off, add
  • Set CHANGEROWS = on

• Default flag for quiet save option: on to show the Quiet Save button, off to hide
  • Set QUIETSAVE = on

• Default edit button: Specify button text, or specify alternate text, image URL
  • #Set EDITBUTTON = Edit table
  • Set EDITBUTTON = Edit this table, /pub/TWiki/EditTablePlugin/edittable.gif

• Date format of Mishoo DHTML calendar:
  • Set JSCALENDARDATEFORMAT = %Y/%m/%d

• Language of DHTML calendar, pointing to attached calendar-<code>.js language file: en, af, br, ca, cs-win, da, de, du, el, es, fr, hr, hr-utf8, hu, it, jp, nl, no, pl, pt, ro, ru, sk, sp, sv, tr, zh
  • Set JSCALENDARLANGUAGE = en

• Additional options of DHTML calendar:
  • Set JSCALENDAROPTIONS =

Note: The Plugin looks for the JSCALENDAR* settings first in the TWiki Preferences, then in above Plugin settings

Limitations and Known Issues

• This Plugin does not support TWiki table formatting like Multi-span cells (e.g. | ... ||) and cell justification (e.g. |  centered  |   right |).
• There is a performance issue when editing a large table, say, with more then 50 rows.
• The Plugin fails if the table is at the very end of the topic (without a new line) Always ensure there is a newline after the table
• Variables like %ATTACHURL% get expanded unless they are in a label.
• You cannot put two %EDITTABLE% statements on the same line in the source.
• You can include %-vars now in select values, by quoting them with <nop>, as in %<nop>X% for %X%, say for instance:
  select,1,%<nop>X%,%<nop>Y%

Plugin Installation Instructions

Note: You do not need to install anything on the browser to use this Plugin. The following instructions are for the administrator who installs the plugin on the server where TWiki is running.

• Download the ZIP file from the Plugin web (see below)
• Unzip EditTablePlugin.zip in your twiki installation directory. Content:

  File:	Description:
  data/TWiki/EditTablePlugin.txt	Plugin topic
  data/TWiki/EditTablePlugin.txt,v	Plugin topic repository
  lib/TWiki/Plugins/EditTablePlugin.pm	Plugin Perl module
  pub/TWiki/EditTablePlugin/edittable.gif	Edit table button image

  pub/TWiki/EditTablePlugin/*.js	Mishoo DHTML calendar JavaScript files
  pub/TWiki/EditTablePlugin/calendar-system.css	Mishoo DHTML calendar stylesheet

• The Plugin depends on the viewauth script to authenticate the user. As described in TWikiAccessControl, copy the view script to viewauth (or better, create a symbolic link) and add viewauth to the list of authenticated scripts in the .htaccess file.
• The Mishoo DHTML calendar 0.9.5 is preinstalled and should work without any configuration. If you wish to use another language, specify the in the Plugin settings, or create a new language files, attach it to the Plugin topic, and change the Plugin settings
• Test if the Plugin is correctly installed:
  • Check above example if there is an [ Edit table ] button below the table in above example
  • Click on [ Edit table ], make changes and save the table
