Geocoder Plugin - markers in incorrect position

Sometimes google maps gets an address/postcode location wrong. For example the position of the marker for my office is approx half a mile away from where it should be (perhaps because I am in a rural part of the country)

Google has the function to move a marker to the correct position when using google places. So now if someone puts my company name into google maps the office is shown correctly.

When using the geocoder plugin the longitude and latitude position uses googles original marker position.

Is it possible to somehow replace this with the manually positioned marker?

Hi,

By the time the points are being output to the map, all the geocoding has already been done, so there wouldn't be a simple way of reconnecting to google to retrieve points. If you're only experiencing this issue with a few records, you could manually get the lat/long of those points and put them into the CMS. Here are a few sites that can help with that:

Hope this helps

I came up with the same solution but the problem with that approach is the cms automatically replaces my manually inputted values with the geocoded ones when the page is saved.

I think, if it is ok with you guys, I would like a refund on the plugin. It is probably easier if I revert to putting the values in manually.

Im planning to buy the newsletter plugin so the money will be coming straight back to you anyway!

Hi Jason

Changing:
$GLOBALS['GEOCODER_AUTOSET_LAT_LNG_FIELDS'] = true;

to

$GLOBALS['GEOCODER_AUTOSET_LAT_LNG_FIELDS'] = false;

Appears to stops any lat/long being generated. It is possible to auto generate the long/lat if the fields are empty but not to auto generate anything if I have already manually inputed the fields?

Hi Jeff,

Yes, this is possible if you make some custom changes to the code.

*Please note that this change has not been tested.

Try this:

First, change $GLOBALS['GEOCODER_AUTOSET_LAT_LNG_FIELDS'] back to true. Then make this code change

// Autoset form lat/lng values if we can make an address from other form values
function geocoder_autosetFormLatLngFields() {

// Skip if autoset isn't enabled or latitude and longitude aren't defined in form
if (!$GLOBALS['GEOCODER_AUTOSET_LAT_LNG_FIELDS']) { return; }
if (!array_key_exists($GLOBALS['GEOCODER_AUTOSET_LAT_FIELDNAME'], $_REQUEST)) { return; }
if (!array_key_exists($GLOBALS['GEOCODER_AUTOSET_LNG_FIELDNAME'], $_REQUEST)) { return; }

// Get address from form field combos
$address = _geocoder_getAddressFromFieldCombos( $_REQUEST );
if (!$address) { return; }

// lookup coordinates
list($lat, $lng) = geocodeAddress($address);

$record = mysql_get(@$_REQUEST['tableName'], @$_REQUEST['num']);
// Skip if record already has lat/lng values
if (@$record[ $GLOBALS['GEOCODER_AUTOSET_LAT_FIELDNAME'] ] && @$record[ $GLOBALS['GEOCODER_AUTOSET_LAT_FIELDNAME'] ]) { return; }


// override form values
if ($lat && $lng) {
$_REQUEST[ $GLOBALS['GEOCODER_AUTOSET_LAT_FIELDNAME'] ] = $lat;
$_REQUEST[ $GLOBALS['GEOCODER_AUTOSET_LNG_FIELDNAME'] ] = $lng;
}
}

This will not overwrite values if they already exist. Keep in mind that if you then change the address, the lat/lng will not be updated.

Hope this helps
