Adobe Director Basics

ADOBE DIRECTOR BASICS
Asynchronous programming
property pNetID -- integer id of the net operation
on mouseUp(me)
me.mStartOperation()
end mouseUp
on enterFrame(me)
if pNetID then
me.mCheckProgress() -- calls mCompleteOperation() when done
end if
end enterFrame
on mStartOperation(me)
vFolder = "http://my.example.com/director/" -- use valid URL
vURI = vFolder&"test.php?input=50"
pNetID = getNetText(vURI)
end mStartOperation
on mCheckProgress(me)
if netDone(pNetID) then
me.mCompleteOperation()
end if
end mCheckProgress
on mCompleteOperation()
vNetError = netError(pNetID)
case vNetError of
"OK", "":
vResult = netTextResult(pNetID)
otherwise: -- an error occurred
vResult = "Error: "&vNetError
end case
pNetID = 0
alert vResult
end mCompleteOperation
If you want to experiment with postNetText(), you can use the following handler instead of the mStartOperation()
handler above.
on mStartOperation(me)
vFolder = "http://my.example.com/director/" -- use valid URL
vURI = vFolder&"test.php"
vData = ["input": 50]
pNetID = postNetText(vURI, vData)
end mStartOperation
PHP scripts are case sensitive. A PHP variable called ‘Input’ is not the same as a variable called ‘input’. This makes it
risky to use symbols as the properties of the property list that acts as the second parameter for the postNetText() call.
Try executing the following lines in the Message window to understand why.
trace(#mixed) -- creates #mixed as a symbol with a lower-case "m"
-- #mixed
trace(string(#Mixed))
-- "mixed"
trace(string(#mixer)) -- built-in symbol with an upper-case "M"
-- "Mixer"
To avoid issues due to the case-sensitivity of PHP scripts, always use strings for the property names in the data property
list sent with a postNetText() call, as shown in the example above.
To test a postNetText() operation, complete with feedback to indicate that something is happening, download and
launch the php.dir.
