Create Joomla Component, Part 2

Previously, has created a simple joomla component. Now, create a joomla component that uses a database.

Step One:
Create a table in the joomla database. Because to make the components nyoba, create a table nyoba. the name of the table as a jos_nyoba. Don’t forget this.

Fields: id, title, comment

Step two:
Create programming.
Write in the file nyoba.php and nyoba.html.php.

On file nyoba.php
Add loop

case 'form:
nyoba::form($option);
break;

on file nyoba.html.php
add the function of the form:

form()
{
Echo”
<form method=’post’ action=’index.php?option=com_nyoba&task=insert’>
Insert Title = <input type=’text’ name=’title’>
<br>
Comment = <input type=’text’ name=’comment’>
<input type=’submit’ value=’process’>
</form>
”;
}:

Third Step
Add loop in the file nyoba.php:

case insert:
nyoba::insert($option);
break;


Add insert function in file nyoba.html.php

$title=$_POST[“title”];
$comment=$_POST[“comment”];
$db=& JFactory::getDBO();

$masuk="INSERT INTO #__nyoba values('', '$title', '$comment')";
$db->setQuery( $masuk);
$mlebu=($db->query());
If($mlebu){
Echo”SAVED”;}

Else
{echo”ERROR”;}

Explanation:

$db=& JFactory::getDBO();.
Calling class and function that serves the connection to the database
in php code: mysql_connect("localhost","root","");
mysql_select_db("jos_nyoba");

#__nyoba
in joomla, # _ means the first name of the table. Here name is Jos, so # _ = Jos. If not Jos (for example, jono), then any tables that use the name: jono_nyoba.

$db->setQuery( $masuk);
in php code: mysql_query($masuk);
