Google Maps - This project leverages v3 of the Google Maps API to provide functionality for capturing latitude/longitude information. Below you will find a detailed list of the various form/element attributes that affect the Google Maps API v3 integration.

preventGoogleMapsLoad - This form attribute is used to prevent the required Google Maps javascript file from being loaded when the form is rendered. If you have multiple forms on a signle page that invoke the addLatLng function, you will need to make use of this attribute to prevent a duplicate include of the Google Maps js file.
latlngDefaultLocation - The "latlngDefaultLocation" form attribute can be used to specify the map's default location when no value is provided. By default, this attribute will be set to array(41.847, -87.661), which places the marker on Chigago, IL.
height - This element attribute controls the height of the Google Map canvas. Its default value will be set to 200.
width - This attribtue controls the width of the Google Map convas. Its default value will be set to 100% of the form's width.
hideJump - Below the Google Map canvas, there's an area provided that allows you to find a latitude/longitude by typing a location into a free-form textbox. This functionality is included because it can be difficult to drag the marker accross large distances. The "hideJump" element attribtue allows you to disable this functionality.
zoom - The "zoom" element attribute controls the default zoom level of the Google Map canvas. If not specified, this attribute will be set to 9.

Below you'll find several ways you can use the addLatLng function in your development.


<?php
$form = new form("googlemaps_0");
$form->setAttributes(array(
    "width" => 500
));

if(!empty($_GET["errormsg_0"]))
    $form->errorMsg = filter_var(stripslashes($_GET["errormsg_0"]), FILTER_SANITIZE_SPECIAL_CHARS);

$form->addHidden("cmd", "submit_0");
$form->addLatLng("Latitude/Longitude:", "MyLatLng");
$form->addLatLng("Latitude/Longitude w/Default Value:", "MyLatLngPrefilled", array(40.689, -74.045));
$form->addLatLng("Latitude/Longitude w/Custom Dimensions:", "MyLatLngDimensions", "", array("style" => "width: 300px;", "height" => 150, "width" => 300));
$form->addLatLng("Latitude/Longitude w/zoom Attribute:", "MyLatLngZoom", "", array("zoom" => 13));
$form->addButton();
$form->render();
?>

    $form->errorMsg = filter_var(stripslashes($_GET["errormsg_1"]), FILTER_SANITIZE_SPECIAL_CHARS);

$form->addHidden("cmd", "submit_1");
$form->addLatLng("Latitude/Longitude w/latlngDefaultLocation Attribute:", "MyLatLng");
$form->addButton();
$form->render();
