Open Project - Invitation for ideas

I am a long time user of Gravity Forms and various add-ons. A pet project has come across my desk to see how far I can push the plugin.

I am creating a team-based adventure race using WordPress and Gravity Forms. (and yes I know there are lots of ready made treasure hunt / scavenger hunt apps out there - but this is more of a project to see what can be done with these systems).

I am after ideas! (Please note, I am not wanting to hire a custom coder - thats not what this is about).

Game: A team registers and is given map coordinates to start. Once there there will be a question about their location which triggers a evergreen countdown timer. They then have that amount of time to complete the race. They will be given two clues to two different locations (their choice). When they get to one of the locations again they confirm with a checkbox, then answer a question about the location. Only then do they get the next clues.

All of this I have built using basic conditional logic, pages and sections and a timer plugin.

Now - here is where I need the brains trust (you)! Hit me with some cool ideas of what we could do and how. I would love to include geolocation triggers. I would love to have them upload a photo of and auto check the location or match against an existing one.

I have thought about using hidden QR codes to trigger certain things and this is a possibility but what else?

Over to you - I will post updates on the project as it develops.


HTML Geolocation API Have them click a “check in” button, then use a little .js and php to populate your hidden lat and long field’s value, if they match the required numbers of conditional logic, display the rest of the form. Leaving in 3-4 decimal places should require them to be close to your determined place while allowing some ‘roaming’ space for the device location triangulation. 00.0001 to 00.0002 is about 11 meters apart.

Perfect - I will try to set this up - I might come back to you to get some advice!!!

Hey midwestsalt - I have got to a point with this but can’t seem to finish it off.

Link is here: The Amazing Property Race – Darling Habour Ferris Wheel – Teambonding

What should happen - use the check in button and if the phone is in the correct position the next section appears using conditional logic.

I can generate the long and lat and use the conditional logic: if [long] starts with …

If I type in the lat and long directly then it works, bit by generating it using the button it doesnt work until you refresh or click into it.

Generating code:

Click the button to confirm your entire team are standing at the correct position. You may be asked for location permission on your device. Please allow this.

Yes - We are here!

Update: solved it:

A little extra code:

function showPosition(position) {

So any other ideas? Hit me up!

UPDATE: OK, so here is the project so far. its developed into a city wide game of monopoly using geo locations, tracking devices and a web app.

Players race to locations on a huge customised monopoly board in teams. When the team reaches a location (with specific location instructions) they use a check in button to check their latitude and longitude - if they are in the right position a file upload button appears with instructions to take a photo, upload it and submit. It gets sent immediately to a dedicated mailbox. Once the moderator running the race checks the photo they reply on the on page chat box to say they are either there first and have purchased the property or its already bought and they owe rent.

There is also a triggered popup box showing a Chance or community chest card at set times and a 2 hour countdown. Lots of other things. I would love to have a facility to overlay a photo so when they switch to their camera an outline overlays they have to match and take a photo. Can’t find a way though am trying.

Some screen shots attached.

Any other ideas?

OK, am getting somewhere with this project. SO far I have the above all tested and implemented. I am playing with WebAR and looking at having the contestants getting to the location and looking for a AR spinning Race card infront of the location.

Two issues: 1: I have a section that shows only when the contestants are in a certain position (checks long and lat to 4 places) but I also want a section that appears if they are NOT in position. But the there is no conditional logic that says “Does not start with…” - How do I go about this?

Next thing is I want it to score itself eventually so that a moderator doesn’t have to sit and keep score and communicate this back.

This is new territory for me but I guess as each form relates to one property, I could put a cost price against each form and using zapier alter an excel sheet keeping score, however how do I get it to check to see if the property has already been sold?
