=== Example: Extracting coordinates from a Location field into Real fields === | |||
Suppose you have a Location field called myLocation. If you would like the coordinates as Real fields, create the Real fields, maybe LocationLatitude and LocationLongitude. The create two triggers, as follows: | |||
:; CreateBefore | |||
:: Event: Creating a new entry | |||
:: Phase: Before saving the entry | |||
:: Script: As follows | |||
<source lang="JavaScript"> | |||
var e = entry(); | |||
var loc = e.field("myLocation"); | |||
if (loc.hasNext) | |||
loc = loc.next(); | |||
e.set("LocationLatitude", loc.lat); | |||
e.set("LocationLongitude", loc.lng); | |||
</source> | |||
:; UpdateBefore | |||
:: Event: Updating an existing entry | |||
:: The rest the same as above. | |||
Now, every time you create a new entry or update an existing one, the coordinates for myLocation will be extracted to the Real fields. | |||
