<h1>Edit Table Plugin</h1>

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 or a row number. Multiple tables per topic can be editable, but only one at a time canbe edited.

---++ <nop>%TOPIC% Global Settings

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

   * One line description, shown in the %TWIKIWEB%.TextFormattingRules topic:
      * Set SHORTDESCRIPTION = Edit TWiki tables using edit fields and drop down boxes.

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

---++ 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 row when editing the table. A cell can be a text input field, a drop down box, a fixed label, or a row number. Cell definitions: <table cellpadding="0" cellspacing="0"><tr><td valign="top">-Text input field (1 line): </td><td> =&#124; text, &lt;size&gt;, &lt;initial value&gt; &#124;= </td></tr><tr><td valign="top">-Textarea input field: </td><td> =&#124; textarea, &lt;rows&gt;x&lt;columns&gt;, &lt;initial value&gt; &#124;= </td></tr><tr><td valign="top">- Drop down box: </td><td> =&#124; select, &lt;size&gt;, &lt;option 1&gt;, &lt;option 2&gt;, etc &#124;= </td></tr><tr><td valign="top">- Fixed label: </td><td> =&#124; label, 0, &lt;label text&gt; &#124;= </td></tr><tr><td valign="top">- Row number: </td><td> =&#124; row, &lt;offset&gt; &#124;= </td></tr><tr><td valign="top">- Date: </td><td> =&#124; date, &lt;sizet&gt; &#124;= </td></tr></table>  | ="text, 16"= for all cells |
| =changerows= | Rows can be added and removed if ="on"=;<br /> Rows can be added but not removed if ="add"= | ="on"= |
| =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) |

__Note:__ 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" |

---++ 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="Quietsave"  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>


---++ 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.
   * %RED% *Warning:* %ENDCOLOR% This plugin uses undocumented functions to read, save and lock a topic. The plugin will likely break in a future TWiki release.
   * 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 %X%, say for instance:
     <br /> =select,1,%&lt;nop&gt;X%,%&lt;nop&gt;Y%=
   * =date= field type for the =format= parameter adds a button popping a javascript 
     calendar to choose the date
     on browsers supporting it.
     It uses the nice *Mishoo DHTML calendar* at http://dynarch.com/mishoo/calendar.epl,
     that should be included in Cairo release, or see TWiki:Codev/JavaScriptDatePickerForForm
     for installing it on Beijing Release

---++ Plugin Installation Instructions

   * 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. 
   * 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
