Wouldn't it be nice if this code would have it's own website where all the documentation could be organised.

+1 !

a simple bitbucket/github whatever site would come in handy with no cost involved.
I think I will never understand why people prefer to spend hours diggin' in a forum and going back and forth to collect and build up their own, subjective little documentation (which differs avg. 25% from those made by others ..)

Hello, i downloaded ExtDirect.zip and unzipped it into my folder. While I don't get any errors on the Developer Web Inspector window in my browser (Safari, Chrome). The results from the date function is not being displayed. What is the next step? What is the next step? Where should I look? do I need to open additional ports (other then 80) in my firewall?

Do you have PHP and a web server (Apache or Nginx or similar) installed and properly configured? Can you run PHP scripts on your machine? You need to be able to run PHP scripts from your folder, and to see the results in your browser.

Does not work with ExtJS 4. Here is an updated version of example.html:

HTML Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
	<head>
		<title>Ext.Direct Example</title>
		<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
		<script type="text/javascript" src="http://extjs.cachefly.net/ext-4.0.2a/ext.js"></script>
		<script type="text/javascript" src="example.php?javascript"></script>
		<script type="text/javascript">
			Ext.onReady( function() { Ext.php.Server.date( 'Y-m-d', function(result){ alert( 'Server date is ' + result ); } ); } );
		</script>
	</head>
	<body>
		<h1>Ext.Direct Example</h1>
	</body>
</html>

And here is an error log from Chrome console:

Code:

example.html:4 Uncaught TypeError: Cannot call method 'addProvider' of undefined
example.html:13 Uncaught TypeError: Cannot call method 'date' of undefined

Hi, Blob,

If you use ext-all.js instead of ext.js, it works.

Code:

http://extjs.cachefly.net/ext-4.0.2a/ext-all.js

If you want to use ext.js, then you need to require the Ext.direct.Manager class:

Code:

Ext.syncRequire( 'Ext.direct.Manager' );

This line of code must be before the Direct API is loaded, like this:

Code:

        <script type="text/javascript" src="http://extjs.cachefly.net/ext-4.0.2a/ext.js"></script>
        <script type="text/javascript">Ext.syncRequire( 'Ext.direct.Manager' );</script>
        <script type="text/javascript" src="example.php?javascript"></script>

I have already updated ExtDirect.php by changing the ExtDirect class. I have not published this new version yet, because there are a few other modifications. The change is in the beginning of the "get_javascript_api" method:

PHP Code:


    /**
     * @return string   JSON encoded array containing the full API declaration
     */
    static public function get_api_javascript()
    {
        $template = <<<JAVASCRIPT

if ( Ext.syncRequire )
    Ext.syncRequire( 'Ext.direct.Manager' );

Ext.namespace( '[%namespace%]' );
[%descriptor%] = [%actions%];
Ext.Direct.addProvider( [%descriptor%] );

JAVASCRIPT;

This is backwards compatible and does the job of requiring Ext.direct.Manager in ExtJS 4.

hi all,

I try to implement this nice class with our framework but I need always a parameter in de registered class.
I mean this:

PHP Code:


<?php

require 'ExtDirect.php';

class Server
{

    function construct__(frame $frame){
       $this->_frame = $frame;
    }

    public function date( $format )
    {
        return date( $format );
    }
}

ExtDirect::provide( 'Server' );

?>

It results in the follow error

PHP Code:


 Warning: Missing argument 1 for TestClient::__construct(), called in ExtDirect.php on line 501

I try to change some things but I am stuck, maybe someone could give me some useful tips?

Thanks,
Freez

Hi, Freez,

The easiest workaround would be to provide a default value for the constructor parameter:

PHP Code:


<?php

require 'ExtDirect.php';

class Server
{

    function construct__(frame $frame = 'default'){
       $this->_frame = $frame;
    }

    public function date( $format )
    {
        return date( $format );
    }
}

ExtDirect::provide( 'Server' );

?>

In fact, this ExtDirect implementation does not send parameters to the class constructor. The only exception is when ExtDirect::$constructor_send_params config is set to true. But, in this case, the action parameters (coming from the client-side) are sent to the class constructor.

Anyway, I am open to suggestions on how to provide parameters to the constructor from the server-side... What do you think? Should a new configuration option be created for this? Something like ExtDirect::$constructor_params ? How would it work?

Maybe like this:

PHP Code:


 <?php
 
 require 'ExtDirect.php';
 
 class Server
 {
 
     function construct__(frame $frame){
        $this->_frame = $frame;
     }
 
     public function date( $format )
     {
         return date( $format );
     }
 }
 
$params = array( 'this is the value for "frame" parameter' );
 ExtDirect::$constructor_params = array( 'Server' => $params );
 ExtDirect::provide( 'Server' );
 
 ?>

What do you think?

Hello!

That sounds very good

! Now I has make a little hack but it always send the constructor parameter.
If you would implement this you are brilliant!

PHP Code:


 
$params = array( 'this is the value for "frame" parameter' );
 ExtDirect::$constructor_params = array( 'Server' => $params );

Thanks,
Freez
