<DIV><FONT size=2>Hi</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Be sure you have at least some knowledge in PHP programmation.
If not, I would strongly suggest either ask for the help of some programmer or
follow some programmation tutorials.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>You have to create a plugin. This plugin will query the
Postgres/postgis database.</FONT></DIV>
<DIV><FONT size=2>You can use the Tables plugin to format the query result, but
that's not an obligation.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Please read carefuly the chapter 2 of the developer manual <A

<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Your plugin will only need a Client part, I
think.</FONT></DIV>
<DIV><FONT size=2>If the data you want to display depends of the layers
selected/displayed, you can get the list of active layers like
this:</FONT></DIV>
<DIV><FONT size=2>$layersPlugin =
$this->cartoclient->getPluginManager()->getPlugin('layers');</FONT></DIV>
<DIV><FONT size=2>$activatedLayers =
$layersPlugin->getSelectedLayers();</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Have a look at the examples in <A
href="http://www.cartoweb.org/cwiki/HowTo">http://www.cartoweb.org/cwiki/HowTo</A> </FONT></DIV>
<DIV><FONT size=2>Im sure there are several pieces of code you can easily
use.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Looking at existing plugins to see what they contain and
how they work can help you a lot too.</FONT></DIV>

<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>I'm an undergraduate of University of Colombo, Sri Lanka. I'm developing
an on-line traffic information system using Cartoweb. I would like to thank u
people for developing such a great piece of software. Anyway I have a small
problem and I would be grateful if u can help me. The problem is this.</DIV>
<DIV> </DIV>
<DIV>The map is generated using data stored in a PostGIS database. When the
map loads in the browser, I want to display some information in a table,
retrieved from the database. (As in the query plugin, but without any user
intervention and it should be automatically displayed when the map loads). As
I feel, I think Tables plugin should be integrated with the layers plugin.
Please help me to achieve this task (how to do this).</DIV>
<DIV> </DIV>
<DIV>So again I would be grateful to u.</DIV>
<DIV> </DIV>
<DIV>Thank you in advance.</DIV>
<DIV> </DIV>
<DIV>Madura</DIV></DIV></DIV><BR>
