Hi Dave, here is the code, it starts with the transition_post_status. Build an address string, geoencodes it and (attempts) to save the lat and long back to the post. If I have the die() it does save it, if I don’t have the die() it does a screen refresh, but nothing is in the lat and long fields.

add_action('transition_post_status','nbpe_publish_project',10,3);

function nbpe_publish_project($new_status,$old_status,$post){
	if ($post->post_type == 'project' && $new_status != 'trash' && $old_status !='new'){
		do_action( 'save_post', $post->ID, $post, true );
		if (get_field('latitude') =='' || get_field('longitude') == ''){
			nbpe_geoencode($post,$post->ID);
		}
	}
 }

// Geoencoding
function nbpe_geoencode($post,$postID){
	$street_number = get_field('street_number');
	$street_direction = get_field('street_direction');
	if ($street_direction == 'NONE'){
		$street_direction = '';
	}
	else{
		$street_direction = $street_direction.'+';
	}
	$street_name = str_replace(' ', '+',get_field('street_name'));
	$street_suffix = get_field('street_suffix');
	if ($street_suffix == 'NONE'){
		$street_suffix ='';
	}
	else{
		$street_suffix = $street_suffix.'+';
	}
	$city = get_field('city');
	$state = get_field('state');
	$zip_code = get_field('zip_code');
	$address_space = '+';
	$address_string = $street_number.$address_space.$street_direction.$street_name.$address_space.$street_suffix.$zip_code;
	$url_string = 'https://maps.googleapis.com/maps/api/geocode/xml?address='.$address_string;

	$xmlStr = file_get_contents($url_string); //Read the XML returned by Google maps API into a string.
	$xmlObj = simplexml_load_string($xmlStr); //Interprets a string of XML into an object.
	$arrXml = objectsIntoArray($xmlObj); // Converts to an array.

	$status = $arrXml['status'];

	if ($status == 'OK'){ //Geoencode was successful, process and add to post.

		$latitude = $arrXml["result"]["geometry"]["location"]["lat"];
		$longitude = $arrXml["result"]["geometry"]["location"]["lng"];

		//echo 'Post ID: '.$postID.'<br />';
		//echo 'Status: '.$status.'<br />';
		//echo 'Lat: '.$latitude.'<br />';
		//echo 'Lng: '.$longitude.'<br />';

		update_post_meta($postID, 'latitude' , $latitude);
		update_post_meta($postID, 'longitude', $longitude);
		die('Why do you save with die???');
	}
}
 function objectsIntoArray($arrObjData, $arrSkipIndices = array())
{
    $arrData = array();

    // if input is object, convert into array
    if (is_object($arrObjData)) {
        $arrObjData = get_object_vars($arrObjData);
    }

    if (is_array($arrObjData)) {
        foreach ($arrObjData as $index => $value) {
            if (is_object($value) || is_array($value)) {
                $value = objectsIntoArray($value, $arrSkipIndices); // recursive call
            }
            if (in_array($index, $arrSkipIndices)) {
                continue;
            }
            $arrData[$index] = $value;
        }
    }
    return $arrData;
}

Hi Dave,
Yes it is called from that function, does the Geoencoding, then updates the post_meta. At that point it exits. If I put a die() there it actually updates the post_meta, if I don’t have the die it goes back to the edit screen and nothing gets saved.
die() must be doing some cleanup that I need to do, just don’t know what.
Thanks again
Gavin

Ok, new problem. The custom post fields are not being updated unless I die(); in my functions.php
Is there something I need to call after this in order to commit it it to the DB?

update_post_meta($postID, 'latitude' , $latitude);
		update_post_meta($postID, 'longitude', $longitude);

If I follow with a die(); it will update the post, if I don’t it doesn’t? WTH??

Thanks,
Gavin

UGH!!!! Thanks Craig! That just kills me! Spent ALL day yesterday trying to figure out what the hell I did wrong, only to find nothing! 🙂
I appreciate your input and help! Means a lot to me!
Gavin

Craig,
Wouldn’t just the publish_post hook any and all postings, both standard as well as CPT?
Thanks,
Gavin
