Loading snippets of code in codeigniter for the view
So I decided to give codeigniter a chance and convert my existing site which is all custom php to the codeigniter framework. But trying to figure out how to do this best in codeigniter that I was doing from my original site. In the original site a person would visit a page such as index.php. In the index.php code its broken into sections like so (This is just a very simple example):
index.php:
<html>
<head></head>
<body>
<div id="top">{$SECTION1}</div>
<div id="main">{$SECTION2}</div>
<div id="bottom">{$SECTION3}</div>
</body>
</html>
Then in my main php file that is included in every single pa开发者_Python百科ge I run a query that grabs all "modules" that are assigned to each section above for the index.php page. So give me all modules that are assigned to {$SECTION1}, {$SECTION2} and {$SECTION3} for index.php. A module in my original system is simply a php file that does a specific job so I might have a module called latest_story.php and in the script it gets the last 10 stories from the database and display the results.
latest_story.php
include('class/story/story_class.php');
$story = new Story($databaseconn);
$latest_story = $story->findLatestStory(10);
//If results back from $latest_story loop through it
//and display it however I want
Then using output buffering I execute each module then take the outputted information from each module assigned to each section and replace that section with the outputted data.
Can this be done in codeigniter? If so can someone point me in the right direction in doing this in codeigniter?
EDIT
To give a more clear view of what Im doing in the original system I run a query on every single page to determine what "modules" to grab for the current page the person is viewing then run this code
foreach($page_modules AS $curr_module)
{
$module_section = intval($curr_module->section);
$module_file = $global_function->cleanData($curr_module->modfile);
$module_path = MODS .$module_file;
if(is_file($module_path))
{
ob_start();
include($module_path);
${'global_pagemod' .$module_section} .= ob_get_contents();
ob_end_clean();
}
}
Then I simply take each variable created for each section and replace {$SECTION[n]} with that variable in the template.
ADDITIONAL EDIT
What Im trying to do is be able to create "modules" that do specific tasks and then in the backend be able to dynamically place these modules in different sections throughout the site. I guess you can say its like wordpress, but a more simplier approach. Wordpress you can add a module and then assign it to your pages either in the left column, middle or right column. Im trying to do pretty much the same thing.
Basically, Codeigniter is an MVC framework. To use it, you really want to embrace that rather than include files. You can rejig your code as:
In your controller:
function example()
{
$this->load->model('story_model','story');
$data['section1'] = $this->story->latest();
$data['section2'] = $this->story->top_stories(5);
$data['section3'] = $this->story->most_popular();
$this->load->view('example', $data );
}
In your model:
function latest()
{
return $this->db->limit(1)->get('stories');
}
etc.
In your view:
<html>
....
<div id="latest">
<h2><?php echo $section1->title; ?></h2>
<?php echo $section1->body; ?>
</div>
<div id="top">
<?php foreach $section2 as $popular { ?>
<h2><?php echo $popular->title; ?></h2>
<?php echo $popular->body; ?>
<?php foreach} ?>
</div>
</html>
If you wanted a second page, with different content but the same layout, you'd add this to your controller:
function second_page()
{
$this->load->model('tags_model','tag');
$this->load->model('authors_model','author');
$data['section1'] = $this->tag->latest();
$data['section2'] = $this->tag->top_tags(5);
$data['section3'] = $this->author->most_popular();
$this->load->view('example', $data );
}
and add in new models etc.
You can pass the retrieved data as an array to the main view and then access that data on the subviews. For example: Main View
$posts = $this->post_model->fetch_all();
$top_data = $this->more_data_model->fetch_more_data();
$data = array('posts'=>$posts,'top_data'=>$top_data);
$this->load->view('main_view',$data);
Then on the main view you load the subviews:
$data = array('data_name'=>$top_data);
$this->load->view('top_view',$data);
And then on the subview you just use the data however you want. There might be a more effective way to do this, but i believe this'll do the trick. :)
I do it like this:
Controller:
function about()
{
$user_session = $this->model_user_lite->Session_Check();
$data['auth'] = $user_session;
$user_id = $this->model_user_lite->Session_UserID();
$data['user_id'] = $user_id;
$this->load->view( 'main_about.php', $data );
}
View:
<? $this->load->view('header_base.php'); ?>
<? $this->load->view('include_standart.php'); ?>
<? $this->load->view('header_standart.php'); ?>
<div class="box">
<div class="box-top"></div>
<div class="box-center">
<div class="content">
<center>
<h2><?= lang('MAIN_ABOUT_CAPTION_TEAM'); ?></h2>
<div class="hr"></div>
...
Header Base:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<link rel="shortcut icon" href="<?= base_url(); ?>/favicon.ico" type="image/x-icon">
<link rel="icon" href="<?= base_url(); ?>/favicon_animated.ico" type="image/x-icon">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta property="fb:admin_id" content="677920913" />
<meta property="fb:app_id" content="<?= FACEBOOK_APPID; ?>" />
<meta property="og:site_name" content="<?= SITE_NAME; ?>" />
<?php if ( empty( $og_title ) === FALSE ): ?>
<meta property="og:title" content="<?= $og_title; ?>" />
<?php endif ?>
...
This way you have a clean file system, seperate header, you can even have more headers just as you like, and can assign all the data from the controller to the view.
**Variables that are assigned from the controller, also go to views loaded by your "main view".
I'm using it in a major dating website and it works like a charm.
