GeoCoder URL Query

Hi,

Yes you can use the GeoCoder to create a search from that allows user to search for events within a certain distance of an address.

They can enter an address, then select from a dropdown the distance (with 5 miles, 10 miles etc). The distance dropdown can be customized with any distance options you want.

If you have any other questions about the GeoCoder, please let me know.

Thanks!

Hi,

So you are trying to retrieve a list of records near the current record. Is that right? If so, you can try a modification of the searching code.

for example (NOTE: this code is untested):

// get geocoding data
list($myLat, $myLng) = geocodeAddress( $record['address'] );
$kmOrMiles = 'miles'; // can be 'miles' or 'km'
$geoOptions = geocoder_getOptions($myLat, $myLng, "100", $kmOrMiles);

// get records
list($addressRecords, $addressMetaData) = getRecords(array(
'tableName' => $GLOBALS['GEOCODER_SAMPLE_TABLENAME'],
'where' => "num != '".intval($record['num'])."'",
) + $geoOptions); // geoOptions WILL NOT override the above options

In this example, we start by geocoding the current record ($record) and setting a radius of 100 miles.

Hope this helps get you started.

Hi Jason,

Thanks for the quick reply. What if I want to implement this code on a mobile device or website that pull user geolocation? How can I insert the user location into the code and then show a list based on a 100 mile radius?

Hi,

There will be a couple of options for you for doing this. Basically, you need to pull the lat/long of the current user (accuracy will vary depending on location). You can either do this on the server side, by querying a 3rd party API to get coordinates based on an IP address (see here http://stackoverflow.com/questions/7766978/geo-location-based-on-ip-address-php)

or you can use javascript on the browser to try to determine the location and use jquery to update your list of "nearby results" (see here: http://en.wikipedia.org/wiki/W3C_Geolocation_API). Your ability to use this second option will depend on the browser being used to at the time.

Hope this helps get you started.
