Once you download the source code, extract it. You will find a folder named Class, under the Class folder you will find XMLRPC folder. We need to import this folder (with the file inside) to our project, and also import NSString+XMLExtensions.h and NSString+XMLExtensions.m.

I will show you how to implement this XML-RPC on simple application.

Start your XCode program, make new “View-based Application” project.

Name the project with “XMLRPC-sayHello”.

Once the workspace opened, import the XMLRPC folder from WordPress source code to our project. Right click on Class folder, Add->Existing files

Then browse to the WordPress for Iphone source code, and select the XMLRPC folder. Click the “Add” button. The next is import the NSString+XMLExtensions.h and NSString+XMLExtensions.m files to our project.

Your project files will be look like this.

Ok the import step is done, now we need to design UI. We will make a simple interface with Label and Button only. The final design will be look like this.

To design the UI, double click the XMLRPC_SayHelloViewController.xib file and the interface builder will show up. On interface builder Drag a label from the library and change the text to “Response”. Next drag the Round Rect Button, and change the text to “Get Response”. Once done, close the interface builder and back to XCode.

Coding

Open the XMLRPC_SayHelloViewController.h, we will import the header files that used for XMLRPC, that are XMLRPCResponse.h, XMLRPCRequest.h, and XMLRPCConection.h. We also declare the label and the getResponse method in our header file. It should be look like this.

Once you done with the XMLRPC_SayHelloViewController.h, double click the XMLRPC_SayHelloViewController.xib to reopen the interface builder, we will connect the code with the interface. Open the Inspector window first Tools->Inspector.

Click the Response label in designer, then in the Inspector window it will be shown “New Referencing Outlet”. Drag the right circle of “New Referencing Outlet” to File’s Owner. See image.

When you release the mouse button, choose the “lblResponse” from the pop up window.

Ok, now select the Button on the interface, and drag the right circle button on the “Touch Down” inspector window to File’s Owner.

Once you finished editing the interface, save it and we continue with the coding.

Open the XMLRPC_SayHelloViewController.m and add the following code.

You can change the server path to your own path, and don’t forget to enable the XMLRPC on your wordpress installation. On wordpress XMLRPC there is demo.sayHello method that returns “hello” string, so I used this for the example.

Tadda! It’s done! Run the emulator by pressing command+enter button. Once running, press the “Get Response” button, that will invoke the getResponse method and show up the result to lblResponse.

This is my first article tutorial in this blog, today my friend have a problem connecting SQL databases with PRaDO framework. I have used this framework several years ago, and it’s quite easy to make a website with Prado. This time I will write how to connect MySQL with Prado, insert data, and display it in the web page.

First, I’m using XAMPPLITE as webserver, XAMPPLITE is lite version of XAMPP, but if you are using XAMPP it’s ok. Download XAMPP.

After you finish the XAMPP download, continue with download Prado framework. Download Prado.

Install the XAMPP, and extract the prado framework in htdocs folder.

The optional prado-cli.php PHP script file in the framework directory provides command line tools to perform various tedious takes in Prado. The prado-cli.php can be used to create Prado project skeletons, create initial test fixtures, and access to an interactive PHP shell. We will use command line tool to generate our prado project.

1. Make setPath

First I made setpath.bat to declare PHP path, so we can called any file in PHP path easier.

Make a file setpath.bat ( I put this file in C:\)

PATH=C:\xampplite\php\;

set the path to your php directory.

2. Generate the Project

Open the command prompt, and execute the setpath.bat by typing the filename setpath.bat

Go to htdocs

Let’s generate project, execute this line

php C:\xampplite\htdocs\prado\framework\prado-cli.php -c pradocontact

When the generate success the command line will display line like this

3. Open in browser

Open your browser and navigate to http://localhost/pradocontact/ if you see the prado welcome page, congratulations you have been generate prado project successly.

4. Create Database

Navigate to http://localhost/phpmyadmin/ and create new database. Type “pradocontact” in create new database field and hit create button.

Then make a new table called “contact” with 2 field (id and name). Set the id field type into tinyint, auto_increment, and as primary key. Set the field name type as varchar and give the length 100.

 
CREATE TABLE `contact` (
`id` TINYINT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`name` VARCHAR( 100 ) NOT NULL
) ENGINE = MYISAM ;
 
After the TABLE created, INSERT 2 rows DATA INTO contact TABLE.
INSERT INTO `contact` ( `id` , `name` )
VALUES (
'1', 'leo'
), (
'2', 'ganda'
);

5. Set connection in application.xml

Browse your project folder and open the protected folder C:\xampplite\htdocs\pradocontact\protected

You will see a file “application.xml”, open it and edit.

<modules>
 
	<module id="db" class="System.Data.TDataSourceConfig">
    <database ConnectionString="mysql:host=localhost;dbname=pradocontact" username="root" password=""/>
  	</module>
 
  	<module class="System.Data.ActiveRecord.TActiveRecordConfig" ConnectionID="db" />
</modules>

We make a ConnectionString to mysql database, dbname is our database that used for this project. Set the username and password with your database account.

6. Create Active Record

To use active record, I will make a new folder called database inside the protected folder to store the ActiveRecord file. After the database folder created, open the application.xml once again, and declare the database path.

<paths>
  <using namespace="Application.database.*" />
</paths>

Your application.xml should be look like this

<?xml version="1.0" encoding="utf-8"?>
 
<application id="pradocontact" mode="Debug">
   <paths>
  <using namespace="Application.database.*" />
  </paths>
 
  <!-- configurations for modules -->
 <modules>
	<module id="db" class="System.Data.TDataSourceConfig">
    <database ConnectionString="mysql:host=localhost;dbname=pradocontact" username="root" password=""/>
  	</module>
  	<module class="System.Data.ActiveRecord.TActiveRecordConfig" ConnectionID="db" />
  </modules>
 
 
  <!-- configuration for available services -->
  <services>
    <service id="page" class="TPageService" DefaultPage="Home" />
  </services>
 
  <!-- application parameters
  <parameters>
    <parameter id="param1" value="value1" />
    <parameter id="param2" value="value2" />
  </parameters>
  -->
</application>

After you finish editing the application.xml, let’s generate Active Record from our database in MySQL.
Open the command prompt again, go to C:\xampplite\htdocs\pradocontact\ and execute php C:\xampplite\htdocs\prado\framework\prado-cli.php shell .

execute generate contact Application.database.ContactRecord

Open your database folder with explorer, and you will find a new file called ContactRecord.php, try to open it.

<?php
/**
 * Auto generated by prado-cli.php on 2009-07-18 03:01:37.
 */
class ContactRecord extends TActiveRecord
{
	const TABLE='contact';
 
	public $id;
	public $name;
 
	public static function finder($className=__CLASS__)
	{
		return parent::finder($className);
	}
}
?>

7. Test The Active Record

Ok, let test our Active Record using command line tools, type “ContactRecord::finder()->findAll()” and hit enter. See the image below.

The command line return an array with 2 record from the mySQL database and that means our activeRecord running well!

8. Edit Home.page

paste this code on your Home.page file

<%@ Title="Contact List" %>

</com:TDataGrid>


9. Make new file Home.php

Paste this code on your Home.php

<?php
class Home extends TPage
{
    /**
     * Populates the datagrid with user lists.
     * This method is invoked by the framework when initializing the page
     * @param mixed event parameter
     */
    public function onInit($param)
    {
        parent::onInit($param);
        // fetches all data account information
        $this->UserGrid->DataSource=ContactRecord::finder()->findAll();
        // binds the data to interface components
        $this->UserGrid->dataBind();
    }
}
?>

10. Make a new file insert.page


<%@ Title="Insert Contact" %>

</com:TForm>


11. Make a new file insert.php

class insert extends TPage
{
 
    public function createButtonClicked($sender,$param)
    {
        if($this->IsValid)  // when all validations succeed
        {
            // populates a UserRecord object with user inputs
            $ContactRecord=new ContactRecord;
            $ContactRecord->name=$this->Name->Text;
 
 
            // saves to the database via Active Record mechanism
            $ContactRecord->save();
 
            // redirects the browser to the homepage
            $this->Response->redirect($this->Service->DefaultPageUrl);
        }
    }
}
 
?>

Navigate your browser to http://localhost/pradocontact/ you will see this page
