Dear All
Thank you Oliver for your detailed advice. I can now retrieve data into the
dropdownlist, although i did not construct a new plug in: wrote an external php
function to retrieve item names from database which i call from ClientEdit
renderform function in edit plugin. My question related to this is: How do i
use this function instead from the Server side so i can take advantage of the
already constructed dsn? ( i now have to make another connection to database.)
Do i need this? I didnt use it and it works! /*<![CDATA[*/

Hi
do it in two phase.
first make a plugin that will return the list of values for the select.
but instead of producing html, simply output a string with the values separated
by comma, like this:
option1,option2, option3, ...
if the option name is different from the option value, simply generate two
string
you do this in the renderform function of your plugin, by setting, for example
$optionNamesList = 'option1name,option2name,...' and $optionValuesList =
'option1value,...'
and in your template, add this somewhere:
<script type="text/javascript"> /*<![CDATA[*/ var optionNamesList =
'{$optionNamesList}';
var optionValuesList = '{$optionValuesList}'; /*]]>*/</script>
this way to can access the options data via the edit plugin javascript
the edit plugin javascript is complex, maybe ask someone who know javascript to
help you with that part
In the actual HowToAddDropdownInEditPlugin example, the options data is written
in hard in the code. All you have to do is, instead, get the optionNamesList
and optionValuesList javascript variable (defined in the template, see above).
so, instead of using
var authorisedOptionsList = new array( ...
var authorisedOptionsListLabel = new array( ...
you use
var authorisedOptionsList = optionValuesList.split(",");
var authorisedOptionsListLabel = optionNamesList.split(",");
this convert the string provided by your other plugin into an array of options
label and value the javascript from the edit plugin can use.

Oliver
Hey all,If i want to use the example given in the wiki for retrieving data from
server (http://cartoweb.org/cwiki/HowToReturnDataFromServerToClient), but i
want to return this data list to the javascript that constructs an edit table
(in edit plugin), how would i do that? I want to combine the above HowTo and
the dropdownlist(http://cartoweb.org/cwiki/HowToAddDropdownInEditPlugin)
HowTo.Am not a pro in these things (javascripts, php)ThanksBroun Uganda
