Function call(passing an argument)

[Eoin]

Firstly i am new to php.Iv currently got this while loop iterating through a database drawing polygons from the info in the datatable.each polygon has its own id stored in the datatable and with the on click event i am trying to just output to the screen the specific id of the polygon clicked on.It looks ok to me but it doesnt work for some reason. Below is the loop and the function it is trying to call.

///////////////////////////////////////////////////////////////////////

<?php

            while($info = mysql_fetch_array( $data )){

                echo "<polygon fill=".$info['fill_colour']." stroke=\"black\" id=".$info['id']." onclick=\"buildingClick(id)\" points=".$info['coordinates']." />";

 

 

        }

?>

///////////THIS IS THE FUNCTION///////////////////////////

<?php

function buildingClick($id) {

 

echo "building id : {$id}";

       

    }

?>

///////////////////////////////////////////////////////////////////

 

If anyone could help it would be hugely appreciated.

PHP executes on the server, onClick is a client side event (JavaScript). The two happen in a completely different context.

I see.would you have any suggestions on what to do as i need to be able to pass in the id.

buildingClick() needs to be a JavaScipt function, not PHP.
