Yes, you can have this setup. The only thing you need to keep in mind is that when a Flash/Flex application makes a request for data to a server different than the originating one, you need to have a crossdomain.xml policy file on that server.

You can read more about crossdomain.xml files here

Please i have question concerning deployement of flex application with Weborb and PHP.
I want to know if it is possible to install Weborb and my PHP to another server instead of installing this on the same web server where *.swf files are?

So in that case i will have tow separated web server, the first with my flex application (user interface) and the other server with Weborb and php code.

Thanks for your help,
Euloge

Can you help me please

Regards

Jorge

I like to send a login simple code that NOT works to you help me.

so, i have stated a remote object with destination id = “genericdestination” and source = “com.myapp.Login”

when i run the app, i get an error saying: unable to load file C:/…/WebORB/Services/genericdestination.php

apparently, it is looking at the destination id in the services-config.xml file to locate the class with the same name which is weird…

i expected it to look for WebORB/Services/com/myapp/Login.php

any thoughts?

I’m sure that you’ll find the solution or advices if you take a look at WebORB website and forum.

I have developed a Flex app with .NET webservices as the
backend. Webservices are deployed beind firewall. How can I access
those webservices from my client side Flex app.

Can I access using proxie using Weborb? If so what is the edition I
need to use. Can any body guide me in this issue?

thanks

public function __construct() {
settype($this->id, “integer”);
}
}

And it works perfectly! Thank you.

How much extra overhead is incurred using this method?

1) Yes, if you do the following:
$a = 1;
$a = “1″;
the type of $a is back a string (unfortunately).
As I’ve said the constructor gets called after member initialization – so the type is converted after the data is set. More accurate way will be:

class dataVO {
public $id;
public function convert() {
$this->id = intval($this->id);
}
….
$r = mysql_fetch…
$r->convert();

}

2) You can use any type cast operation you like for example:

$a = (int)$a;
$a += 0;
settype($a,$type);

Any of that method gives the same result (IMHO)
except that settype gives you the opportunity to perform:

$vars = array (“String”, “123″, “0″);
$types = array (“string”, “integer”, “boolean”);

for ($i = 0; $i < 3; ++$i) {
settype($vars[$i], $types[$i]);
}

PS: The fastest way considered to be $a += 0;

$id = “1″;

id is now a string, despite you setting its type to integer.

I’ve used the VO constructor to set data type.
However I’ve found that when using mysql_fetch_object, the constructor gets called after data initialization :O)
Anyway, this approach works and saves data fetching functions from ugliness :O)

class gDataVO {
public $id;
public $name;

public function __construct() {
settype($this->id, “integer”);
}
}

//define variable as a string
myvar = “true”;

//define variable as a boolean
myvar = true;

My question remains: Is there a way to specify the variable type in the VO?

If so, set your value as a boolean in php as follows

if ( $row->mybool == 0 ){
$row->mybool = false;
}else{
$row->mybool = true;
}

I know that I could loop through the array in php manually, but this seems a bit clumsy. Is there a way to specify the variable type in the actual php VO?

I will play a little bit with the ZF and Zend AMF. What would you like to see?

Regarding MVC in the context of Flex and PHP with Zend Framework, here the things are a little bit different compared to “traditional” web apps (HTML).

Flex is a SOA technology. As a result, when you create a Flex application that brings data from the server, you’ve already achieved some MVC: you have a clean separation between the presentation of the data (the Flex client), and the Server side (business logic/persistance layer in DB).

However, usually you go a little bit further, by implementing MVC in the Flex side too, especially with large projects or teams.

Will there be any articles on using the ZF and ‘adding on’ the flex frontside? I like the ZF mvc structure and would like to keep using it in development.

Thanks

Right-click to get the source codes.

Here is my current class:

[RemoteClass(alias="VOLoad")]
[Bindable]
public class VOLoad
{
public var id:int;
public var adr:Boolean;
public var label:String;
public var loc_street:String;
public var loc_city:String;
public var loc_country:String;
public var dest_street:String;
public var dest_city:String;
public var dest_country:String;
public var start_date:Date;
public var end_date:Date;
public var space:int;
public var weight:int;
public var description:String;
public var notes:String;
public var company_id:int;
}

When I receive this back from the server I create an arraycollection with the returned objects as follows

myLoadDP = new ArrayCollection(ArrayUtil.toArray(event.result));

then I use this arraycollection as a dataprovider for my datagrid. I want to get the start_date and end_date fields to render in the dataGrid but also be editable with a dropin itemEditor. I have and event trigger on the oneditend event on the datagrid to save the data back to the server and this is why I need to send the date back to mysql in the same format I fetched it in. My application is very similar in function to the one you created here Mihai, maybe you could add a Date column to this and expand the tutorial? Pretty please? ;o)

a: get the dataGrid to render the date as a date instead of the number

b: get the DateField itemEditor to use the rendered date and allow me to save the chosen date back to the Number type

http://d6142393.u89.hosting365.ie/application.rtf

(TypeError: Error #1034: Type Coercion failed: cannot convert 1175001854629 to Date.)

Do I need to write a function for this also? It seems odd that Flex does not do this automatically since it can display the date.

Ok, I can’t copy the source codes here.

Please get it from my server:

http://alekkus.com/download/convert_date_in_datagrid.rtf

On flex end, use Number data type for your object. Then use labelFunction on the column to convert the timestamp to date. Here’s the source codes:

I am using an array of the returned objects as a dataprovider for a datagrid. So the server sends the unix timestamp to flex as a number, flex expects a Date. At what point should the conversion to Date object be done?

As mentioned in my previous comment, I would suggest you using Unix timestamp format. That means you use int/Number as the data type. In this way, you can compare dates easily using SQL statements when comparing dates. Also, since it’s an int, sending it to Flex will not pose any problem.

On your Flex end, just call new Date() to create a Date object.

For all other properties, int, String, Number etc. the data can be saved in MySQL in the format received from Flex, but not for the Date type. MySQL dates have a different format so should I store as a number/string or some other format?

What I would like to understand is this: What is the best way to store a Flex Date object in a MySQL database so that it is easy to pass Date values to and from MySQL and Flex using Remote Objects with Zend AMF.

It would be fantastic if you could demonstrate a working method as I have struggled for several days to find and adequate solution.

Thanks, Conor

How should look the tutorial? Maybe I have some time to write one.
