Time for action – making the location card work

The Location card has three fields in it for latitude, longitude, and a title for the location. The user could type in the details manually, but if they happen to be at the location in question, there's a button there that will grab the location and fill in the numbers automatically. The following steps will guide you in making the location card work:

  1. Edit the script of the Set to Current Location button and type in the following lines of code:
    on mouseUp
  mobileStartTrackingSensor "location", true
  put mobileSensorReading("location", false) into tLocation
  mobileStopTrackingSensor "location"
  set the itemdelimiter to comma
  if the number of items in tLocation = 3 then
    put item 1 of tLocation into field "latitude"
    put item 2 of tLocation into field "longitude"
  end if
end mouseUp
  2. Nothing too tricky here; we just captured the location and stored the latitude and longitude entries in the two fields.
  3. Edit the script of the Cancel button and change it to the following easy script:
    on mouseUp
  go to card "home"
end mouseUp
  4. For the last item for this card, edit the Add Location button script and type in the following code:
    on mouseUp
  global gReminderData
  if field "location name" is empty then
    answer "Please enter a name for this location."
    exit mouseUp
  end if
  if field "latitude" is empty or field "longitude" is empty then
    answer "Please enter location values, or press the 'Set to Current Location' button."
    exit mouseUp
  end if
  put "Location" & tab & field "location name" & tab & field "latitude" & tab & field "longitude" into tLocationDetails
  if gReminderData = "no entries yet" then
    put tLocationDetails into gReminderData
  else
    put return & tLocationDetails after gReminderData
  end if
  go to card "home"
  showdata
  writedata
end mouseUp

    Most of the handler just checks whether the user entered the required information.

What just happened?

A lot less has happened than what happened on the first card! However, it was important all the same. Now, we have a way where the user can set up a location to be used by the reminders that they have created. That's where we're headed now…

The reminder entry form

This last card is essentially an entry form; we just want to ask the user what the reminder is for. There are some tricky aspects to it though and one or two lengthy functions to cope with that.
