Re: [flexcoders] AMFPHP Question
Last time I made a data driven app with AMFPHP. I used PHP and MySQL. I did
all of what your describing within PHP and MySQL.
Everytime I querried the database, I always sent back the same kind of
object to Flex. The object always had two properties, a success¹ property
and a message¹ property. IF the query succeeded, then my object that I
created in PHP would be:
success¹ = true; message¹ = query executed successfully.
Or if it failed it would be.
success¹ = false; message¹ = [enter your custom error message here. I.e.
record already exists¹]
I suggest making your remote object responses in a format that you repeat,
like this:
mx:RemoteObject id=myRemoteObject
mx: method name =insertRecord result
=¹_onInsertRecordResponse(event)/
mx:RemoteObject/
private function _onInsertRecordResponse (evt:ResultEvent) : void
{
if(evt.result.success) // remember I¹m returning an object with a
success¹ and a message¹
{
Alert.show(event.result.message) // output query execurted
seccessfully¹
}
Else if (!evt.result.success)
{
Alert.show(event.result.message) // outputs record already exists¹
// my custom error message I made in PHP
}
}
This way, every result handler, from every remote object is in my app is
structured the same way.

[flexcoders] AMFPHP Question
Hi all,
I have following issue, which I don't understand.
I created a button which will add a record to the database. But before
doing so I need to check if a similar record already exists.
This is how I thought it could be solved:
mx:RemoteObject id=myRemoteObject
mx: method name =existRecord result
=recordExistResultHandler(event)/
mx:RemoteObject/
if (myRemoteObject.existRecord.send(myRecord)) {
Alert.show (Record already exists)
} else {
// Insert record into the database
myRemoteObject.insertRecord.send(myRecord)
}
private function recordExistResultHandler (evt:ResultEvent) : Boolean {
Alert.show (Result getting back from webserver is +
evt.result.toString());
return evt.result;
}
The function existRecord on the webserver checks if a similar record
already exists and sends a Boolean back. This works fine.
To my opinion this should work as follows (supposing record is already
in the database) :
- Before executing my if-statement, it will check the condition (check
if record already exists)
- it send a request existSpell to the webserver which will query the
database
- num_rows is greater dan zero (meaning record already exists), the
webserver will return TRUE to the resultHandler of flex-application
- resultHandler is executed -- an Alert-windows appears telling Result
getting back ...is TRUE and the value is returned to the
if-statement.
- Because condition is true -- an Alert-window appears telling Record
already exists
BUT ... THIS IS NOT HOW IT WORKS ?
As a matter of fact the if-statement is executed first (Alert 'Record
already exists') and afterwards I get the Alert telling the result of
the webserver???
It's the opposite world.
Am I missing something??
Thanks
RE: [flexcoders] AMFPHP Question
ALL RPC data service calls, including RemoteObject are *asynchronous*. And
such calls are non-blocking. You must invoke your check call, then, in its
result handler, do the conditional logic to invoke the insert.

[flexcoders] AMFPHP Question -- Flex 2
Hi People ! Just following through Mike Potter's example of integrating AMFPHP with Flex2, notice that with the following code http://www.adobe.com/devnet/flex/articles/flex2_amfphp_03.html Flex cannot recognize the gateway = new RemotingConnection( http://localhost/flex/php/gateway.php; ); line -- it thinks that there is no RemotingConnection method. Does anyone have any ideas? Also does anyone know of sample code which demonstrates adding editing deleting records as well ? Thanks for any help Prema
