[Chameleon] query pop-up with photo?

[Jason Fournier]

If I'm understanding correctly ...

If you use the methodology listed in the FAQ on the Chameleon Tiki you 
shouldn't have to worry about where the information is coming from (ie, 
local, WMS) ... it should be returned to you as an array from the 
executeQuery function.

In the case of the FAQ example the sample query.phtml file should be 
created in the same directory as your template.  The myOnQuery 
javascript function that you create in your template refers to 
query.phtml being accessed by, for instance, a window.open:

function myOnQuery( nX, nY )
{
    var url = 'query.phtml?x=' + nX + '&y=' + nY + '&sid=' + 
document.forms0.sid.value;
    window.open(url,'eventwin','width=675,height=600,
directories=no,location=yes,menubar=no,scrollbars=yes,
status=no,toolbar=no,resizable=yes');
}

In your query.phtml you can use PHP to limit the resulting datasets, 
refer to images, etc. etc.

In the instance you describe you could do something like:

<?php

//snippet - additional code still required above as note in the tiki

     foreach( $aResults as $nLayerIdx => $aResult )
     {
         $oLayer = $oMapSession->oMap->getLayer($nLayerIdx);
         $szName = $oLayer->name;

         if( $szName == 'NAME_OF_LAYER_DESIRED' )
         {
             echo 'fieldA: ' . $aResult['fieldA'] . '<br>';
             echo 'fieldB: ' . $aResult['fieldB'] . '<br>';
             echo 'fieldC: ' . $aResult['fieldC'] . '<br>';
             echo '<img src="./images/'.$aResult['fieldPhoto'].'"><br>';
         }
     }

?>

(Note: the above isn't tested!)

That should be it ... you should get the results you want.  The above 
query.phtml is a snippet of the code shown in the FAQ - you require all 
the other stuff in order for it to work.  As well, the above loop will 
basically drop the query information for any other queryable layer in 
your application.  If you want to query other layers you'll have to add 
that logic to your script.
