Question

i have this array in my lua…

local data = {}

data[1] = {}
data[1].title = "Crazy Song"
data[1].subtitle = "by Bruno Earth"
data[1].image = "note.png"

data[2] = {}
data[2].title = "Enter Sunman"
data[2].subtitle = "by Mentalica"
data[2].image = "note.png"

data[3] = {}
data[3].title = "Bitter Child of Mine"
data[3].subtitle = "by Gunz n bullets"
data[3].image = "note.png"

data[4] = {}
data[4].title = "Missed A thing"
data[4].subtitle = "by Ero-Smith"
data[4].image = "note.png"

data[5] = {}
data[5].title = "Pornstar"
data[5].subtitle = "by Nicklefront"
data[5].image = "note.png"

data[6] = {}
data[6].title = "Burner"
data[6].subtitle = "by Asher"
data[6].image = "note.png"

how can i get the array values by not using id on it. i just want to get the title for my conditional statement?

i try this in my code:

local getTitle = function(event)
    print (".................")
    print (event.target.id)
    print (event.target.title)
end

but i got only this…

touch: began
touch: ended
.................
2
nil

how can i get and print the title of my array?

this is my code:

module(..., package.seeall)
display.setStatusBar( display.HiddenStatusBar ) 
function new()
    local localGroup = display.newGroup()
    local tableView = require("tableView")
    local ui = require("ui")

    --------------------------------------------------------------------------
    local screenOffsetW, screenOffsetH = display.contentWidth -  display.viewableContentWidth, display.contentHeight - display.viewableContentHeight

    local songList
    local backBtn
    local detailScreenText

    local background = display.newRect(0, 0, display.contentWidth, display.contentHeight)
    background:setFillColor(0, 0, 0)
    localGroup:insert(background)

    local data = {}
    --iPad: setup a color fill for selected items
    local selected = display.newRect(0, 0, 50, 50)  --add acolor fill to show the selected item
    selected:setFillColor(67,141,241,180)  --set the color fill to light blue
    selected.isVisible = false  --hide color fill until neede
