Hi Zicky, 

For any of the GeoCoder search forms, such as the example form: 

  • Plugins > GeoCoder > Example Code > Proximity search with results sorted by distance

You can specify the "fromAddress" as Latitude, Longitude with a comma in the middle, eg: 49.282729,-123.120738

So you could make a button that requested the users current location from the navigator.geolocation browser API and then set the value of the fromAddress to their Lat,Lng coordinates.

Hope that helps!

Thanks for the guidance Dave,

I tooled around with this a little and got it working. Not going to say it's the cleanest solution, but it's working and that's a start. Not so sure about the line in bold ( <?php echo (@$_REQUEST['fromAddress'] = $gotGeo); ?> ), but it seems to work.

Now comes the fun part... integrating this into a much larger build. My head hurts and I haven't even started it. I'll give your guys a call if I can't get it figured out.

For anyone else interested in messing around with HTML Geolocation  here's what I built so far.

<?php header('Content-type: text/html; charset=utf-8'); ?>

  // get geocoding data
  list($myLat, $myLng) = geocodeAddress( @$_REQUEST['fromAddress'] );
  $kmOrMiles           = 'miles'; // can be 'miles' or 'km'
  $geoOptions          = geocoder_getOptions($myLat, $myLng, @$_REQUEST['maxDistance'], $kmOrMiles);

  // get records
  list($addressRecords, $addressMetaData) = getRecords(array(
    'tableName'     => 'listings',
  ) + $geoOptions);  // geoOptions WILL NOT override the above options

  // error checking
  $errorsAndAlerts = '';
  if (@$_REQUEST['search']) {
    if     (!@$_REQUEST['fromAddress']) { $errorsAndAlerts .= "No address entered!<br/>\n"; }
    elseif (!$myLat || !$myLng)         { $errorsAndAlerts .= "We couldn't determine your location, please try again!<br/>\n"; }
