Auto Post Using Javascript

leoganda — Sat, 05 Dec 2009 12:37:05 +0000

Hi there, a few weeks ago I was doing research about auto post from webpage to paypal payment page. The basic idea is the visitor fill the form, then when the visitor submit the form we will store visitor data input to database. Once data stored in database the page will be automatically redirected to paypal website. It’s pretty easy, we will use JavaScript to do auto post. I wanna make this article as simple as possible, I just wanna show how to do auto post with Javascript.

1. Database

We will use simple database for this experiment, single table with 4 columns ( id, first_name, last_name, package).

CREATE TABLE `javascriptpost`.`sales` (
`id` INT( 6 ) NOT NULL AUTO_INCREMENT ,
`first_name` VARCHAR( 30 ) NOT NULL ,
`last_name` VARCHAR( 30 ) NOT NULL ,
`package` VARCHAR( 10 ) NOT NULL ,
PRIMARY KEY ( `id` )
) ENGINE = MYISAM ;

2. Form (index.php)

First we need a basic form for user to input, data will be posted to post.php.


	
								
				
				First Name
				
				
				
				Last Name
				
								
				
				Package

3. Post.php

In post.php we will retrieve the posted data from index.php and store the data to database.
Once data stored, the pages will be redirected to paypal website.

We will use javascript syntax to do autopost,

<script language="JavaScript">
var time = null
function subm() {
document.getElementById('paypal').submit();
}
script>

post.php

 

if ( isSet($_POST['first_name']) )
{
	$firstname=$_POST['first_name'];
	$lastname=$_POST['last_name'];
	$package=$_POST['package'];
 
	switch($package)
	{
		case "A": $amount=10;break;
		case "B": $amount=20;break;
		case "C": $amount=30;break;
		default : $amount=0;
	}
 
	$sql = "INSERT INTO sales (first_name,last_name,package) values ('$firstname','$lastname','$package')";
	$con = mysql_connect("localhost","root","");
	if (!$con)
	  {
	  die('Could not connect: ' . mysql_error());
	  }
 
	mysql_select_db("javascriptpost", $con);
	mysql_query($sql);//insert to database
}
?>

            	Thank you for booking                
                Now we will redirect to payment page

Solving Zend Framework error “An Error Has Occurred A project profile was not found”

leoganda — Thu, 15 Oct 2009 02:39:22 +0000

Hi there, I had an error “An Error Has Occurred A project profile was not found” on Zend framework command line when I tried to generate an action for my project. I’m using Windows XP and for the web server I’m using XAMPP. The “An Error Has Occurred A project profile was not found” happened because we have wrong include path in our php.ini.

Open your php.ini and find the include_path line, insert your zend framework library path into the line before the PEAR path.

include_path = ".;E:\xampp\htdocs\ZendFramework\library;E:\xampp\php\PEAR"

Save the file and restart your Apache. Good luck

How to enable XAMPP SSL socket transport

leoganda — Sun, 26 Jul 2009 13:37:06 +0000

Hi today I have an experiment with GData in Zend Framework PHP , and found an error that my XAMPP prevent SSL socket transport and return this error.

Fatal error: Uncaught exception 'Zend_Gdata_App_HttpException' with message 'Unable to Connect to ssl://www.google.com:443. Error #24: Unable to find the socket transport "ssl" - did you forget to enable it when you configured PHP?'

Here’s the solution to make your XAMPP support socket transport SSL.
1. First stop your Apache service
2. Find libeay32.dll and ssleay32.dll in xampp\php\ folder, and copy it into xampp\apache\bin\ folder. Just overwrite the older files in there.
3. Edit php.ini file in xampp\apache\bin, remove the semicolon in “;extension=php_openssl.dll”
4. Start the Apache service

That’s it, your SSL transport socket in your XAMPP has been activated.

How to connect MySQL in Prado Framework

leoganda — Sat, 18 Jul 2009 16:00:55 +0000

Hello!

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.

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

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.

>
   namespace="Application.database.*" />
>

Your application.xml should be look like this

 version="1.0" encoding="utf-8"?>
 
 id="pradocontact" mode="Debug">
   >
   namespace="Application.database.*" />
  >
 
  
 >
	 id="db" class="System.Data.TDataSourceConfig">
     ConnectionString="mysql:host=localhost;dbname=pradocontact" username="root" password=""/>
  	>
  	 class="System.Data.ActiveRecord.TActiveRecordConfig" ConnectionID="db" />
  >
 
 
  
  >
     id="page" class="TPageService" DefaultPage="Home" />
  >
 
  
>

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.


/**
 * 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" %>


Contact List

Create New Contact




DataKeyField="id"

AutoGenerateColumns="false"

>

HeaderText="ID"

DataField="id" />

HeaderText="Name"

DataField="name" />

9. Make new file Home.php

Paste this code on your Home.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" %>



Insert Contact

Name:

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

Ok, thanks for reading. Have a nice day!
