Well I’m sorry, it’s been so long for this part to come.. I had been working very hard on some clients and don’t have enough time to write. Here’s what I had been done if you’re curious :) : http://maps.GpsTrackingIndonesia.com, www.SunberryCorp.com, www.mypushme.com, www.kulacak.com, www.web2trace.com, www.pushmeportal.com, … The fun is almost all of them was written with CodeIgniter :).
Ok, let’s start with the easiest one first. We will create a simple menu page that contains links to other modules on the system. We put it on the Mainpage controller class.
Look at the Mainpage.php controller file. There is a function on it named exactly the same with the filename: Mainpage(). This should be exactly the same including the case. This is the constructor or initialization function of the class. Each time the class is called or instantiate, this function is called automatically. We put some initialization lines inside it:
{
parent::Controller();
$this->load->helper(‘url’);
}
The line parent::Controller() calls the constructor function of this class’s parent constructor which is the CodeIgniter’s Controller class so that it has all the properties and method of it’s parent.
Then, we load a helper library that contains helper functions related to URL handling such as site_url() to return the site’s URL that we are working on. Other functions on this helper are: anchor(), base_url(), uri_string(), etc. You can check it all on the user guide http://localhost/user_guide/helpers/url_helper.html.
Again, look at the Mainpage.php file. We added a new function called index(). This function is analogous to the index.html file in static web page. It’s called by default when we point our browser to the Mainpage controller, ie: http://localhost/index.php/Mainpage.
{
$this->load->view(‘header’);
$this->load->view("main_menu");
$this->load->view(‘footer’);
return;
}
On the function, we load view files. Here we divide the view into 3 pieces: header, main_menu, and footer. They are basically just regular PHP files dealing with display templates. This will make us easier to manage the look of our application later.
All of the view files should be located under system/application/views folder on CodeIgniter file structure. So we need to create all of them:
The header.php view file, contains the opening HTML tags, HEAD, TITLE and start of BODY. Later we can add CSS link definition here:
<html>
<head></p><p><title>Cashbook application</title>
</head>
<body>
</p>
The footer.php view file, just a closing BODY and HTML tag, but you can later add your copyright notice, timestamps, etc:
</body> </html>
And the main_menu.php view file. Here we write a list of links to modules that we are going to develop later:
<ul>
<li><?=anchor("Cashbook/addNew/receive","Cash Receive Entry")?>
<li><?=anchor("Cashbook/addNew/out","Cash Out Entry") ?>
<li><?=anchor("Cashbook/viewReport","Cash Book Report")?>
</ul> </p>
<p><p>Bank Book</p>
<ul>
<li><?=anchor("Bankbook/addNew/receive","Bank Receive Entry");?>
<li><?=anchor("Bankbook/addNew/out","Bank Out Entry");?>
<li><?=anchor("Bankbook/viewReport","Bank Book Report");?>
</ul> </p>
<p><p>Manual Journal</p>
<ul>
<li><?=anchor("Journal/addNew","Manual Journal Entry")?>
<li><?=anchor("Journal/viewReport","Manual Journal Report")?>
</ul> </p>
<p><p>Report</p>
<ul>
<li><?=anchor("Mainpage/trialBalance","Trial Balance")?>
<li><?=anchor("Mainpage/balanceSheet","Balance Sheet")?>
<li><?=anchor("Mainpage/profitLoss","Profit and Loss")?>
</ul> </p>
<p><p>Posting and COA</p>
<ul>
<li><?=anchor("Mainpage/doPosting","Post transaction")?>
<li><?=anchor("Coa/listCoa","Chart of Account Setting")?>
</ul></p>
As we can see above, we call a helper function anchor(). This function will create a standard HTML anchor link based on your local site URL. So for example, if we call it achor(“Mainpage/trialBalance”, “Trial Balance”) then it will return this string:
<a href=”http://localhost/Mainpage/trialBalance”> Trial Balance </a>
assumed that you have configured your site URL as http://localhost/ on the config.php file.
Now we can run our application by pointing the browser to http://localhost and it should return something like the following:
Congratulation!
Next we will begin to code the COA module.
