Zoom to custom extent - PHP

[William Bronsema]

Kevin,

You will need to add a chunk of code like this:

**********************************************************
// check if quick zoom is requested
if ( isset( $http_form_vars['ViewRegion'] ) && strlen(
$http_form_vars['ViewRegion'] ) > 0 )
{
    // separate values
    $adExtents = explode( ',', $http_form_vars['ViewRegion'] );

    // set extent
    $oMapSession->oMap->setExtent( $adExtents[0], $adExtents[1],
$adExtents[2], $adExtents[3] );
}
***********************************************************

to your <application>.php file probably just after the navigation code.
(Note, you indicated that you built your app using maplab.  This code
snippet is built with that in mind - but has not been tested ;) )

HTH

Regards,
Bill
