---+!! 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= | Enable static header if ="on"=, e.g. disable editing of the first row;<br /> Else specify the header format of a new table like ="&#124;*Food*&#124;*Drink*&#124;"=. | (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% - Text input field (1 line):%BR% &nbsp; =&#124; text, &lt;size&gt;, &lt;initial value&gt; &#124;= %BR% - Textarea input field:%BR% &nbsp; =&#124; textarea, &lt;rows&gt;x&lt;columns&gt;, &lt;initial value&gt; &#124;= %BR% - Drop down box: %BR% &nbsp; =&#124; select, &lt;size&gt;, &lt;option 1&gt;, &lt;option 2&gt;, etc &#124;= %BR% - Fixed label: %BR% &nbsp; =&#124; label, 0, &lt;label text&gt; &#124;= %BR% - Row number: %BR% &nbsp; =&#124; row, &lt;offset&gt; &#124;= %BR% - Date: %BR% &nbsp; =&#124; date, &lt;size&gt;, &lt;initial value&gt;, &lt;DHTML date format&gt; &#124;= | ="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 |
| =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>TWIKIWEB%/TWikiDocGraphics/edittopic.gif"=; hide button, e.g. ="hide"= (Note: Automatically hidden if 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. It uses the nice [[http://dynarch.com/mishoo/calendar.epl][Mishoo DHTML calendar]], see also TWiki:Codev/JavaScriptDatePickerForForm <br clear="all">


---++ Per Cell Settings

The edit field type can be defined for each table cell by placing an =%<nop>EDITCELL{ "type, ..." }%= variable after 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, e.g. to define a text field, type: =| cell content %<nop>EDITCELL{ "text, 20" }% |=

It is also possible to place the edit button into 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 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

<form>
   * In page view mode:
      * <input type="submit" name="et"   value="Edit table" onClick="return(false);" /> - turn the table into edit mode
   * In edit mode:
      * <input type="submit" name="etsave"   value="Save table"  onClick="return(false);" /> - save your changes
      * <input type="submit" name="etqsave"   value="Quiet save"  onClick="return(false);" /> - save your changes without alerting subscribed WebNotify users
      * <input type="submit" name="etaddrow" value="Add row" onClick="return(false);" /> - add row to the table (if enabled)
      * <input type="submit" name="etdelrow" value="Delete last row" onClick="return(false);" /> - remove last row from the table (if enabled)
      * <input type="submit" name="etcancel" value="Cancel" onClick="return(false);" /> - cancel without saving and release edit lock
</form>

---++ Examples

Line before table: =%<nop>EDITTABLE{ header="|*Nr*|*Text field sandbox*|*Drop down sandbox*|*Timestamp*|" format="| row, -1 | text, 20, init | select, 1, one, two, three, four | label, 0, %<nop>SERVERTIME{"$day $mon $year $hour:$min"}% |" changerows="on" }%=
%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 *[&nbsp;Edit&nbsp;table&nbsp;]* button above; when you click on it you get this form:

<form>
<table border="1" cellspacing="1" cellpadding="0">
<tr><th bgcolor="#99CCCC"> Nr </th><th bgcolor="#99CCCC"> Text field sandbox </th><th bgcolor="#99CCCC"> Drop down sandbox </th><th bgcolor="#99CCCC"> Timestamp </th></tr>
<tr><td  bgcolor="#FFFFFF"> 1<input type="hidden" name="etcell2x1" value="1" />  </td><td  bgcolor="#FFFFFF"> <input type="text" name="etcell2x2" size="20" value="hello table" />  </td><td  bgcolor="#FFFFFF"> <select name="etcell2x3" size="1"> <option selected="selected">one</option> <option>two</option> <option>three</option> <option>four</option> </select>  </td><td  bgcolor="#FFFFFF"> 26 Jun 2002 12:30<input type="hidden" name="etcell2x4" value="26 Jun 2002 12:30" />  </td></tr>
<tr><td  bgcolor="#FFFF99"> 2<input type="hidden" name="etcell3x1" value="2" />  </td><td  bgcolor="#FFFF99"> <input type="text" name="etcell3x2" size="20" value="" />  </td><td  bgcolor="#FFFF99"> <select name="etcell3x3" size="1"> <option>one</option> <option selected="selected">two</option> <option>three</option> <option>four</option> </select>  </td><td  bgcolor="#FFFF99"> 27 Jun 2002 12:40<input type="hidden" name="etcell3x4" value="27 Jun 2002 12:40" />  </td></tr>
</table>
<input type="submit" name="etsave"   value="Save table" onClick="return(false);" />
<input type="submit" name="etqsave"   value="Quiet save"  onClick="return(false);" />
<input type="submit" name="etaddrow" value="Add row" onClick="return(false);" />
<input type="submit" name="etdelrow" value="Delete last row" onClick="return(false);" />
<input type="submit" name="etcancel" value="Cancel" onClick="return(false);" /> (demo only, these buttons do not work)
</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">
You get:
%EDITTABLE{ format="| label | text, 40 |" changerows="off" }%
|*Key*|*Value*|
| Name: | John Smith |
| Gender: | M %EDITCELL{select, 1, , F, M}% |
| DOB: | 1999/12/31 %EDITCELL{date, 10}% |
| City: | New York |
</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 %TWIKIWEB%.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 text for edit button:
      * Set EDITBUTTON = Edit table

   * Date format of [[http://dynarch.com/mishoo/calendar.epl][Mishoo DHTML calendar]]:
      * Set JSCALENDARDATEFORMAT = %Y/%m/%d

   * Language of DHTML calendar, pointing to attached =calendar-&lt;code&gt;.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 =%<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%=

---++ 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 ==%TOPIC%.zip== in your twiki installation directory. Content:
     | *File:* | *Description:* |
     | ==data/TWiki/%TOPIC%.txt== | Plugin topic |
     | ==data/TWiki/%TOPIC%.txt,v== | Plugin topic repository |
     | ==lib/TWiki/Plugins/%TOPIC%.pm== | Plugin Perl module |
   * The Plugin depends on the =viewauth= script to authenticate the user. As described in %TWIKIWEB%.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 *[&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
