Can you print the value of the URL you’re calling? I just tried to hand build the URL using my local latitude and longitude and I got [] back.  It’s possible you’re URL you’re actually using in your app is not returning any values from the script.

#103

Did you mean to just do print(URL)? which was:

URL = “http://107.170.34.199/barber_search_script.php?” … “currentLat=” … currentLocation.latitude … “&currentLng=” … currentLocation.longitude

it prints:

nil

#104 
local URL = "http://107.170.34.199/barber\_search\_script.php?" .. "currentLat=" .. currentLocation.latitude .. "&currentLng=" .. currentLocation.longitude print( URL ) network.request( URL, "GET", networkListener, params)
#105

tried that, nothing comes out in the console

#106

Can you post your current function handling your network request?

#107 
local function testEvent(event) local phase = event.phase if phase == "ended" then --params.body = "currentLat=" .. currentLocation.latitude .. "&currentLng=" .. currentLocation.longitude local URL = "http://107.170.34.199/barber\_search\_script.php?" .. "currentLat=" .. currentLocation.latitude .. "&currentLng=" .. currentLocation.longitude print(URL) network.request( URL, "GET", networkListener, params) return true end end

local function networkListener( event ) print( json.prettify( event ) ) if ( event.isError ) then print( "Network error: ", event.response ) else print ( "Success!" ) myTable = json.decode(event.response) print(event.response) print(myTable[1].distance) end end
#108

Can you change the print(URL) to print(“URL:”, URL, “*****”)

It can’t be nil or an empty string.

#109 
local function testEvent(event) local phase = event.phase if phase == "ended" then --params.body = "currentLat=" .. currentLocation.latitude .. "&currentLng=" .. currentLocation.longitude local URL = "http://107.170.34.199/barber\_search\_script.php?" .. "currentLat=" .. currentLocation.latitude .. "&currentLng=" .. currentLocation.longitude print("URL:", URL, "\*\*\*\*\*") network.request( URL, "GET", networkListener, params) return true end end

console now doesnt output anything, i also moved the print event.response to be after print myTable[1].barberid in the network listener, so now not even the empty ’ [] ’ are being shown

local function networkListener( event ) print( json.prettify( event ) ) if ( event.isError ) then print( "Network error: ", event.response ) else print ( "Success!" ) myTable = json.decode(event.response) print(myTable[1].distance) print(event.response) print(myTable[1].barberid) end end
#110

You have to be getting some thing printed for the URL line. You don’t need to test this part on a device. Your Corona console log in the simulator should be sufficient to see these print statements.

Rob

#111

the network request takes currentLocation in the URL, which are only defined if myMap is true, which it isnt in the simulator

#112

You dont have a variable named “debug” do you?

#113

i dont!

#114

This line: print(“URL:”, URL, “*****”)

has to be outputting something unless there are runtime errors just before it. Can you post your build.settings?

Do you have something like this:   showRuntimeErrors = false,

in your config.lua or do you have something like:

Runtime:addEventListener( “unhandledError”, myUnhandledErrorListener )

in your code anywhere?

#115

I agree, this has been giving me a headache all day. I really dont understand why its not outputting anything at all in the console, and i dont see any runtime erros before it.

build.settings:

settings = { iphone = { plist= { UIBackgroundModes = {"remote-notification"}, UIApplicationExitsOnSuspend = false, NSLocationWhenInUseUsageDescription = "We need location services in order to specify appointment locations!", UIPrerenderedIcon = true, UIStatusBarHidden = false, NSAppTransportSecurity = { NSExceptionDomains = { NSAllowsArbitraryLoads = true, ["coronalabs.com"] = { NSIncludesSubdomains = true, NSThirdPartyExceptionAllowsInsecureHTTPLoads = true }, ["youtube.com"] = { NSIncludesSubdomains = true, NSThirdPartyExceptionAllowsInsecureHTTPLoads = true }, ["google.com"] = { NSIncludesSubdomains = true, NSThirdPartyExceptionAllowsInsecureHTTPLoads = true }, }, }, }, }, orientation = { default = "portrait", supported = { "portait", "portraitUpsideDown", }, }, android = { usesPermissions = { -- Required by the MapView to fetch its contents from the Google Maps servers. "android.permission.INTERNET", -- Optional permission used to display current location via the GPS. "android.permission.ACCESS\_FINE\_LOCATION", -- Optional permission used to display current location via WiFi or cellular service. "android.permission.ACCESS\_COARSE\_LOCATION", "com.google.android.c2dm.permission.RECEIVE", }, usesFeatures = { -- If you set permissions "ACCESS\_FINE\_LOCATION" and "ACCESS\_COARSE\_LOCATION" above, -- then you may want to set up your app to not require location services as follows. -- Otherwise, devices that do not have location sevices (such as a GPS) will be unable -- to purchase this app in the app store. { name = "android.hardware.location", required = false }, { name = "android.hardware.location.gps", required = false }, { name = "android.hardware.location.network", required = false }, }, }, plugins = { ["plugin.OneSignal"] = { publisherId = "com.onesignal", }, ["plugin.google.play.services"] = { publisherId = "com.coronalabs", supportedPlatforms = { android=true, ["android-kindle"]=true }, }, }, }

and no to the rest of the questions!

#116

So apparently I had a function that i forgot to delete in my code that was interfering with the testEvent, I now got it to print the URL, but when i try to print myTable[1].barberid nothing is output. Heres the output from json.prettify:

I/Corona  (12244): URL: *****

last line is the output of print(event.response)

#117

Your data is now basically:

myTable[1].barberid = 2

myTable[1].distance = 0.05304

myTable[2].barberid = 5

myTable[2].distance = 0.05304

myTable[3].barberid = 6

myTable[3].distance = 0.05304

#118

That’s what i thought too, but print(myTable[1].barberid) isnt outputting anything in the console.

#119

Try changing your PHP script from:

echo json\_encode($barbers);

to

echo json\_encode($barbers, JSON\_NUMERIC\_CHECK );

Your numeric array keys ($q) is being converted to a string and so are other number items. Try that and see if it behaves better.

Rob

#120

Tried that, still isn’t printing anything to the console
