Programmer wannable attitude

Well, Grasshopper, or Unschooled Acolyte, or whatever your title of choice may be…

You did not hear this from me.

But most developers belong to the Church of Pain and we pride ourselves on our arcane talents, strange cryptic mumblings and most of all, the rewards due the High Priesthood to which we strive to belong.

Let me put it bluntly. Some of this very complicated logic is complicated because it’s very complicated. And pretty little tools would do both the complexity and us injustice, as high priests or priests-in-training of these magical codes.

One day we will embrace simple graphical tools. But only when we grow bored and decide to move on to higher pursuits of symbolic reasoning; then and not a moment before will we leave you to play in the heretofore unimaginable sandbox of graphical programming tools. Or maybe we’ll just design some special programs that can program on our behalf instead, and you can blurt out a few human-friendly (shiver) incantations, and watch them interpret and build your most likely imprecise instructions into most likely unworkable derivative codes. Or you can just take up LOGO like they told you to when you were but a school child in the… normal classes.

Does that answer your impertinent question?

procedural MVC in php

Well I am reading some question on http://programmers.stackexchange.com/questions/184664/mvc-pattern-on-procedural-php regarding procedural MVC in php. Then I am thinking why it should not be possible? After all MVC is about architecture, You can make good architecture also in procedural programming. You just need to design proper architecture. As I checkout on MVC Frameworks, their are some common terms like

  • Bootstrap script, which initializing system, core services, routers.
  • Controllers
  • Models
  • Views

Also library, helpers are available depend on project wise.

Now I am giving you some light on, How a MVC (very basic of course ) can be built on following style.

Architecture

Project Root
    config
        config.php
    lib
        core.php
    controllers 
        UserController.php
        BaseController.php
    models
        User.php
    views
        user 
            index.php
        base 
            welcome.php
    resources
        css
            style.css

config.php Sample Code :

define('MODEL_DIR', 'models');
define('VIEW_DIR', 'views');

$config = array (
    'default_module' => 'base', 
    'default_action' => 'index',
);

lib/core.php Sample Code :

function safe($param) {
    return addslashes($param);
}

function render($file, $data)
{
    $layout_file = VIEW_DIR.'/layouts/layout.php';
    ob_start();
    include_once($file);
    $content = ob_get_clean();
    include_once($layout_file);
}

Bootstrap index.php Sample Code :

Let Request url is like /index.php?module=user&action=index

require_once('config/config.php');
require_once('lib/core.php'); // For some core functions like render
//require_once('lib/db.php');   // For DB Abstraction [ Later Improvement ] 

$module = isset($_REQUEST['module'])?safe($_REQUEST['module']):$config['default_module'];
$action = isset($_REQUEST['action'])?safe($_REQUEST['action']):$config['default_action'];

$controller_file = 'controllers/'.ucfirst($module).'Controller.php';
if(!file_exists($controller_file))
{
    trigger_error('Invalid Controller');
    exit;
}
require_once($controller_file);
$function = strtolower($module).'_controller_'.$action;
if(!function_exists($function))
{
    trigger_error('Invalid Controller Action');
    exit;
}
call_user_func($function, $_REQUEST);

BaseController.php Sample Code :

function base_controller_index($request)
{
    render(VIEW_DIR.'/base/welcome.php', array());
}

UserController.php Sample Code :

function user_controller_index($request)
{
    require_once(MODEL_DIR.'/User.php');
    $data = user_model_list($request);
    render(VIEW_DIR.'/user/index.php', $data);
}

function user_controller_add($request)
{
}

function user_controller_edit($request)
{
}

function user_controller_view($request)
{
}

Model User.php Sample Code :

function user_model_list($request)
{
    return array(
        array('name' => 'test', 'sname' => 'test1', 'city' => 'testc'),
        array('name' => 'abc', 'sname' => 'xyz', 'city' => 'mno'),
    ); 
}

function user_model_add($request)
{
}

function user_model_edit($request)
{
}

function user_model_view($request)
{
}

Layout file views/layouts/layout.php Sample Code :

<html>
<head>
<link rel=’stylesheet’ href=’resources/css/style.css’ type=’text/css’ media=’all’ />
<head>
<body>
<div><h1>Logo</h1></div>
<div><h2>Heading</h2></div>
<div class=”content”>
<?php echo $content ?>
</div>
<body>
</html>

View views/base/welcome.php Sample Code :

<i>Welcome</i>
<p>
<a href=”?module=user&action=index”>User Listing Page</a>
</p>

View views/user/index.php Sample Code :

<table class=”listing”>
<thead>
<tr>
<th>First Name</th>
<th>Last Name</th>
<th>City</th>
</tr>
<thead>
<tbody>
<?php foreach($data as $row) { ?>
<tr>
<td><?php echo $row[‘name’] ?></td>
<td><?php echo $row[‘sname’] ?></td>
<td><?php echo $row[‘city’] ?></td>
</tr>
<?php } ?>
<tbody>
</table>
