Failing at Flex

[smangold]

I used amfphp with Flash AS2 quite happily for years. I have been trying
for some time to graduate to Flex and amfphp 1.9 but have not been
successful. I am trying to use the sephiroth tutorial. I have
successfully completed the Hello World tutorial and also successfully
passed a PHP array to Flex, using the instructions in the second part of
the tutorial.

Unfortunately for me, there is no third part of the tutorial which shows
how to pull data from a MySQL database. I am reasonably confident that I
am correctly accessing the database. But that's about it.

I created a MySQL database using the same data that is used in part 2 of
the tutorial. The part that I think is problematic is:

    if (!$Link) {
       printf("Can't connect to MySQL Server. Errorcode: %s\n",
mysqli_connect_error());
       exit;
    }
   
    if ($Link) {  
        $Result = array();
        $Query = "SELECT firstName, lastName, phone, email from $TableName";
        $result = mysql_query($Query);
       
           while ($row = mysql_fetch_array($result)) {
        $stuff = new Person();
        $stuff->firstName = $row['firstName'];
        $stuff->firstName = $row['lastName'];
        $stuff->firstName = $row['phone'];
        $stuff->firstName = $row['email'];
        $Result[] = $stuff;
}
return $Result;
        }
       
        mysql_close ($Link);

When I run the Flex application, I get a Deliveryindoubt error.

If I look at the service through the browser, I get:

TypeError: Error #1009: Cannot access a property or method of a null
object reference.
    at RawAmfService/readData()
    at flash.events::EventDispatcher/dispatchEventFunction()
    at flash.events::EventDispatcher/dispatchEvent()
    at flash.net::URLLoader/onComplete()

Being new to Flex, I don't know how to begin to troubleshoot this thing.

Can someone help?

TIA.

Sue

Susan,

There is a Flex and AMFPHP tutorial on How To Forge.

Susan,

Download the Adobe PHP RIA kit. There is an excellent, simple example  
in there that has a nice and to the point example pulling and  
inserting data with mysql.

http://www.adobe.com/devnet/flex/articles/flex_php_sdk.html

That is what had gotten me going with flex/amfphp/mysql.
