---+!! Edit Table Plugin

This plugin allows you to edit TWiki tables using edit fields and drop down boxes. Tables have an *[&nbsp;Edit&nbsp;table&nbsp;]* button if preceeded by an =%<nop>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.

%TOC%

---++ Per Table Settings

Add a =%<nop>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 ="%VBAR%*Food*%VBAR%*Drink*%VBAR%"=. 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:%BR% %BB% Text input field (1 line):%BR% &nbsp; =%VBAR% text, &lt;size&gt;, &lt;initial value&gt; %VBAR%= %BR% %BB% Textarea input field:%BR% &nbsp; =%VBAR% textarea, &lt;rows&gt;x&lt;columns&gt;, &lt;initial value&gt; %VBAR%= %BR% %BB% Drop down box: %BR% &nbsp; =%VBAR% select, &lt;size&gt;, &lt;option 1&gt;, &lt;option 2&gt;, etc*<nop> %VBAR%= %BR% &nbsp; =*= only one item can be selected %BR% %BB% Radio buttons: %BR% &nbsp; =%VBAR% radio, &lt;size*&gt;, &lt;option 1&gt;, &lt;option 2&gt;, etc %VBAR%= %BR% &nbsp; =*= size indicates the number of buttons per line in edit mode %BR% %BB% Checkboxes: %BR% &nbsp; =%VBAR% checkbox, &lt;size*&gt;, &lt;option 1&gt;, &lt;option 2&gt;, etc %VBAR%= %BR% &nbsp; =*= size indicates the number of checkboxes per line in edit mode  %BR% %BB% Fixed label: %BR% &nbsp; =%VBAR% label, 0, &lt;label text&gt; %VBAR%= %BR% %BB% Row number: %BR% &nbsp; =%VBAR% row, &lt;offset&gt; %VBAR%= %BR% %BB% Date: %BR% &nbsp; =%VBAR% date, &lt;size&gt;, &lt;initial value&gt;, &lt;DHTML date format&gt; %VBAR%= | ="text, 16"= %BR% for all cells |
| =changerows= | Rows can be added and removed if ="on"=;<br /> Rows can be added but not removed if ="add"= | =CHANGEROWS= %BR% Plugin setting |
| =quietsave= | Quiet Save button is shown if ="on"=, hidden if ="off"= | =QUIETSAVE= %BR% Plugin setting |
| =include= | Other topic defining the EDITTABLE parameters. The first %<nop>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 %<nop>STARTINCLUDE% and %<nop>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, %<nop>PUBURL%/%<nop>SYSTEMWEB%/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= %BR% Plugin setting |

---+++ Initial Values

By default, variables in =&lt;initial value&gt;= (of text input field) and =&lt;label text&gt;= (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

<img src="%ATTACHURLPATH%/EditTablePluginCalendarExample.gif" alt="Edit Table Calendar Example" width="549" height="210" align="left"  />
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. 


---++ Per Cell Settings

An individual edit field type can be defined for each table cell. Place an =%<nop>EDITCELL{ "type, ..." }%= variable at the end of the cell content. This is useful to override the per column =%<nop>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 %<nop>EDITCELL{ "text, 20" }% |=

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

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

---++ Table Buttons

   * In page view mode:
      * <input type="submit" name="et"   value="Edit table" onclick="return(false);" /> - turn the table into edit mode

</form>

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.

<table><tr><td valign="top">
You type:
<pre>
%<nop>EDITTABLE{ format="| label | text, 40 |" }%
|*Key*|*Value*|
| Name: | John Smith |
| Gender: | M %<nop>EDITCELL{select, 1, , F, M}% |
| DOB: | 1999/12/31 %<nop>EDITCELL{date, 10}% |
| City: | New York |
</pre>
</td><td valign="top">
Screenshot:
<img src="%ATTACHURLPATH%/ScreenshotEditCell1.gif" alt="EDITCELL Example in view mode" width="149" height="141" />
</td><td valign="top">

</td></tr></table>

---++ Plugin Settings

Plugin settings are stored as preferences variables. To reference
a plugin setting write ==%<nop>&lt;plugin&gt;_&lt;setting&gt;%==, for example, ==%<nop>EDITTABLEPLUGIN_SHORTDESCRIPTION%==

   * One line description, shown in the %SYSTEMWEB%.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

   * Set JAVASCRIPTINTERFACE to 1 to be able to directly move and delete row without page refresh.
      * Set JAVASCRIPTINTERFACE = 1
   
   * 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, %ATTACHURL%/edittable.gif

__Note:__ The Plugin uses base settings like date format, language and style from the JSCalendarContrib.

---++ 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
   * Variables like =%<nop>ATTACHURL%= get expanded unless they are in a label
   * You cannot put two =%<nop>EDITTABLE{}%= statements on the same line in the source
   * You can include %-vars now in select values, by quoting them with &lt;nop&gt;, as in %&lt;nop&gt;X% for %<nop>X%, say for instance:
     <br /> =select,1,%&lt;nop&gt;X%,%&lt;nop&gt;Y%=



---++ Installation Instructions

   * Download the ZIP file from the Plugin web (see below)
   * Unzip ==%TOPIC%.zip== in your ($TWIKI_ROOT) directory.
   * Alternatively,
      * Manually resolve the dependencies listed below.
      None
   * The Plugin depends on the =viewauth= script to authenticate the user. As described in %SYSTEMWEB%.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.
   * (Dakar) Visit =configure= in your TWiki installation, and enable the plugin in the {Plugins} section.
   * Test if the Plugin is correctly installed:
      * Check above example if there is an *[&nbsp;Edit&nbsp;table&nbsp;]* button below the table in above example
      * Click on *[&nbsp;Edit&nbsp;table&nbsp;]*, make changes and save the table
