Solved it now. I was looking for $map->“zoom..”
but $map->“setextent” was the answer. From:
[EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Volkan Ulukut Ok here is the code. I don't think it's a wrong order issue
since i’m not changing any values. $oExtents =
$oMapSession->oMap->extent; $oldExtents = $oExtents; $oLayer =
$oMapSession->oMap->getLayerByName($http_form_vars['sLayer']); $result =
$oLayer->queryByAttributes($http_form_vars['sAttribute'], "/" .
$http_form_vars['sString'] . "/", MS_SINGLE); $oLayer->open(); $oRes =
$oLayer->getResult(0); $oShape =
$oLayer->getShape($oRes->tileindex,$oRes->shapeindex); $oExtents = $oShape->bounds; $oShape->free(); $width=$oMapSession->oMap->width; $height=$oMapSession->oMap->height; $oMapSession->oMap->zoomrectangle(
$oExtents,$width,$height,$oldExtents); Ends up with: Fatal error:
[MapServer Error]: msCalculateScale(): Invalid image extent, minx=-31.418490,
miny=75.002064, maxx=-31.418490, maxy=75.002064. On red line -----Original Message----- REMEMBER to cc the list. PHP mapscript is ok, it was not afffected. Probably you are not
using the correct order for minx, miny, etc. Umberto On 6/12/06, Volkan Ulukut < > I'm using mapserver 4.8.3. mapscript was compiled with it.
