[Cartoweb-users] Cannot clear drop-down list selections

Wed Oct 21 08:42:03 EST 2009

Dear Miguel

as far as I can see, the View plugin has never been adapted to be used with
ajax. so any action done through ajax will not update the piece of template
with the view inputs.

adapting a plugin to response to ajax is not really complicated though and
if you feel at ease with php, you should be able to do it.
note that in this case, a full ajaxification of the plugin is not needed.
here is what should be done:

in ClientView.php
- add Ajaxable to the list of "implements" in the plugin class definition.
- add an ajaxGetPluginResponse function to return the plugin template. it
should return the same as the existing renderForm function. all ajaxified
plugin now have a common function renderFormPrepare which is used by both
ajaxGetPluginResponse and renderForm.
- add a ajaxHandleAction function, it only need to contains
"$pluginEnabler->enablePlugin('view');"
(look at ClientOutline.php and ClientBboxHistory.php for examples)

- create a new View.ajax.js file, using the same structure as the related
file in other plugins (look atBboxHistory.ajax.js), but you dont need to
define any action, simply change the code in the handleResponse function so
the html returned from php is updated correctly in the template. Because
javascript need an element id as target to be able to replace it's content,
you may have to enclose the whole view template inside a <div
id="choose_an_id_which_make_sens">...</div> (for example
$('bbox_history_form') will access the div <div id="bbox_history_form">
...</div>)
- add that new View.ajax.js file in your cartoclient.tpl header
- clean your cache with a cw3setup --clean
and your should be done.

have a look at the plugin outline and BboxHistory, the modifications are
quite straightforward.
also more details are available in the doc about ajax elements and pieces of
code http://www.cartoweb.org/doc_head/docbook/xhtml/user.ajax.html

kind regards
Oliver
