I create a simple home page making at first the controller that point to it.Now inside the home page I have some links that point to another page.since I'm a newbie I' asking to what those link have to point?maybe to others controllers that points to another pages? If so, which could be the best way to implement those controller in the index page?
Don't understand well your question, but links to other pages are controllers/methods that build those pages.
You can also use the built-in methods to build a correct url for CI. Load the URL helper (autoload it or use $this->load->helper('url');) and you can use:
Link to page
That (the site_url() function) would build a correct (for CodeIgniter) link to www.yoursite.com/index.php/controller/method.
In your controller then you'll need to create the function (method) you asked for, and load the appropriate views.
Ex: Write an entry
will map to controllers/blog.php:
class Blog extends CI_Controller{
function write()
{
$this->load->view('write_form');
}
}
But CI's possibily the best documented framework out there, so refer to the manual and this will be soon very clear.
I think this page has all the answers for you: http://codeigniter.com/user_guide/helpers/url_helper.html
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class home extends CI_Controller {
public function __construct()
{
parent::__construct();
error_reporting(E_ALL & ~E_NOTICE);
$this->load->helper('form');
}
public function _remap()
{
$segment_1 = $this->uri->segment(1);
switch ($segment_1) {
case null:
case false:
case '':
$this->check();
break;
case 'mani':
$this->mani();
break;
default:
$this->check();
break;
}
}
public function check()
{
echo "hasgdhsad";
}
public function mani(){
echo "index";
}
}

in codeigniter I have my main controller:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Main extends CI_Controller
{
public function index()
{
$this->load->library('../controllers/forum');
$obj = new $this->forum();
$obj->test();
}
}
And the controller I'm trying to access:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Forum extends CI_Controller
{
function __construct()
{
echo "testing1";
$this->load->library('session');
parent::__construct();
$this->load->database();
$this->load->model('model_forum');
}
public function index(){
}
public function test(){
echo "testing2";
$this->data['forums'] = $this->model_forum->getForums();
$this->load->view('homepage', $this->data);
}
}
Everything is fine with my model_forum.php file, because it works if I put all the code in Main controller. But if I'm trying to access Forum controller, nothing works, only "testing1" echo goes through. Picture of error:
Anyone has any idea what I'm doing wrong? I'm new to PHP and codeigniter so I'm struggling a little bit. Thanks in advance.
You can't load a controller from a controller in CI - unless you use HMVC or something.
You should think about your architecture a bit. If you need to call a controller method from another controller, then you should probably abstract that code out to a helper or library and call it from both controllers.
UPDATE
After reading your question again, I realize that your end goal is not necessarily HMVC, but URI manipulation. Correct me if I'm wrong, but it seems like you're trying to accomplish URLs with the first section being the method name and leave out the controller name altogether.
If this is the case, you'd get a cleaner solution by getting creative with your routes.
For a really basic example, say you have two controllers, controller1 and controller2. Controller1 has a method method_1 - and controller2 has a method method_2.
You can set up routes like this:
$route['method_1'] = "controller1/method_1";
$route['method_2'] = "controller2/method_2";
Then, you can call method 1 with a URL like http://example.com/method_1 and method 2 with http://example.com/method_2.
Albeit, this is a hard-coded, very basic, example - but it could get you to where you need to be if all you need to do is remove the controller from the URL.
You could also go with remapping your controllers.
From the docs: "If your controller contains a function named _remap(), it will always get called regardless of what your URI contains.":
public function _remap($method)
{
if ($method == 'some_method')
{
$this->$method();
}
else
{
$this->default_method();
}
}
I am developing a web app using codeigniter framework. My application has a fixed header and footer.I want to middle section (ie the body) of my application to load when the user goes to various pages which are available to him and make the header and footer constant.
(hackerrank.com ... I was talking about a website similar to this one ... after login into this website ... the header and the sidebar of this remains constant and they load the remaining page ... how can we implement it using CI framework)
Is there any way through which I can achieve this?
I am performing the following actions which is making me to load the complete website(Its like reloading the entire page :/)
As You can see the following code is present in my template.php
<?php
$this->load->view("templates/header.php");
$this->load->view($main_body);
$this->load->view("templates/footer.php");
?>
and I Controller I write the following piece of code usually
public function load_page(){
$data['main_body'] = 'dashboard_pages/dashboard_view';
$this->load->view('template.php',$data);
}
You were pretty close to the solution: Load the header and the footer as they are, variables:
<?php
$this->load->view($header);
$this->load->view($main_body);
$this->load->view($footer);
?>
The tricky thing, is that you're always writing the method function load_page() in every controller you write, and it would be better having a MY_controller, a class previous to your controller class in which you'll write which footer you're referring:
Check for writing a MY_Controller here: http://ellislab.com/codeigniter/user-guide/general/core_classes.html
Then, write your MY_Controller:
class MY_Controller extends CI_Controller {
function __construct()
{
parent::__construct();
}
public function load_page( $page )
{
$data['main_body'] = $page;
// Logic for your header or footer deppending on logging or whatever...
if ( 1 ==1 ) {
$data['header'] = "templates/header.php";
$data['footer'] = "templates/footer.php";
}
$this->load->view('template.php',$data);
}
}
and you'll have to make sure your controllers extends MY_Controller class, and add a load_page method to whom you'll pass the argument:
class Custom_page extends MY_Controller {
function __construct()
{
parent::__construct();
}
function index()
{
$this->load_page( 'dashboard_pages/dashboard_view' );
}
}
I think with that you'll have exactly what you look for, that way you only have to write in one place the logic for the header and footer: In MY_Controller, and just use it in any part.
I have a question which regards to controllers. Let's get it started:
I have a main controller named "admin.php", it has a menu for company, user management, etc. Each item on the menu has separate PHP file to hold different kinds data [I seems to be lengthy to combine them all in one php.
So for this example:
I have 3 controllers: admin.php , company.php, usermanagement.php
What I want is, link the company and management controllers as a child of admin. So if enter the address on the browser, it may look: localhost/admin/company and localhost/admin/usermanagement
I configured the routes and it's good but when I enter "localhost/company" it loads the company page which i didn't want to. i wanted to link them all as a child of an admin page.
How would I achieve this?
by the way here's a snippet of my code:
admin.php - Controller
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Admin extends CI_Controller {
function __construct(){
parent::__construct();
session_start();
}
public function index() {
$this->load->view('view_admin');
}
}
Company - Same as the admin
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Company extends CI_Controller {
function __construct(){
parent::__construct();
session_start();
}
public function index() {
$this->load->view('view_company');
}
}
Thanks,
James
EDIT: I have tried adding functions on the admin.php like:
function company() {}
function usermanagement() {}
but I guess it wasn't that effective since it will include lots of functions later on as I try to migrate my native php codes into this MVC architecture framework.
If your issue is that you like the way routes work but don't want people to be able to visit index.php/company/ and rather prefer that they visit admin/company you can always do:
class Company extends CI_Controller {
public function __construct() {
parent::__construct();
if ( $this->uri->segment(1) != "admin" ) {
redirect('admin/company/'.$this->uri->segment(3));
}
}
...
Although bear in mind that you would probably need a more complete URL forming method than just adding $this->uri->segment(3) but the general pattern is there.
You can add more functions in your 'admin' controller, so, default page is:
public function index() {
$this->load->view('view_admin');
}
'Subpage' is:
public function company() {
$this->load->view('view_company');
}
etc, etc...
I have various static pages and I dont want to create independent controller for them all.
Say I want to create a controller named page and have all of the static pages as functions.
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Page extends Frontend_Controller {
public function index()
{
}
public function store(){
$this->load->view('public/store');
}
public function contact(){
$this->load->view('public/contact');
}
public function about(){
$this->load->view('public/about');
}
}
Is there anyway to modify the URI routes so that I wouldnt have to type mydomain.com/page/contact but I could type mydomain.com/contact to view the page
In your application/config/routes.php
You can add as:
$route['contact'] = "page/contacts";
$route['store'] = "page/store";
...
In my application/config/routes.php I use the following regex to do that. Most sites I work on are relatively small so I list all of the controllers in the following snippet (because it's easier than listing all of the static pages)
$route['^(?!controller1|controller2).*'] = "page/$1";
The logic basically says that If the path does not start with controller1 or controller2 then use page as the controller for urls like http://domain.tld/page
For not having to create 10+ static routes for all my static pages it keeps it pretty simple.
I'm going to do my first site in code ignitor, a fairly basic site like this:
home
login / register
members area
protected page 1
protected page 2
protected page 3
general info section
page 1
page 2
page 3 (dynamic table of reports)
about section
page 1
page 2
blog section
listing
article page
I've gone through a couple of basic tuts and have read some of the documentation but still feel unsure on what would be the best way to structure this. Could anyone that is experienced with CI show me an example of how they' do it?
some specific Qs are:
header with nav panel will be the same on all pages. normally i'd code that as an include with if/else to show highlighted current section. I guess I'd just keep this as an include (view) and either load it first via the controller or include it in every view?
I'd envisage having a model called 'user' which will handle the login and registration, a model called 'blog' and a model called 'reports'. Does that sound right?
for static sections like about, I guess there'd be no model and i'd just have a controller with a function for each static page? i.e. about.php with page1(), page2() and all they do is load static views?
1 -> To fix this problem, I decided to use my own controller like this
Using CI 2.x, create a file under app/core called MY_Controller.php like so :
<?php
class MY_Controller extends CI_Controller {
function __construct() {
parent::__construct();
}
public function loadView($view) {
$this->load->view('header');
$this->load->view($view);
$this->load->view('footer');
}
}
And then I extend this controller instead of the CI one. Be sure that your $config['subclass_prefix'] = 'MY_'; in the config.php file.
2-> yes
3-> thats about it :D
I'm a newbie here (codeigniter) but:
For headers/footers I adopted the template strategy from here (first alternative). Worked nice.
Before models, I'd plan the controllers -roughly one per each section. I made all them inherit from a MY_controller here I place common funcionalilty. And yours models seems about right to me. I think them rathar as DAOs, or "service objects" that provide access to the database and not much more. GEneral intelligence of the site (if needed) should be in a custom library, or inside the controllers.
Yes.
You should use an CI library to handle your user registration and per page authorisation.
Here's a very simple example on how you could do it. Keep in mind that CI uses the MVC pattern
class Reports extends CI_Controller {
public function __construct() {
parent::__construct();
// load database if needed
// load a model if needed
}
public function page() {
//get the page requested
$page_id = $this->uri->segments(2);
// based on the page_id do something.
$data['somedata'] = 'About us data here';
// this is an actual file loaded from the template view
$data['maincontent'] = 'my_page';
$this->load->view('template',$data);
}
}
class About extends CI_Controller {
public function __construct() {
parent::__construct();
// load database if needed for this page
}
public function page() {
// same here
//get the page requested
$page_id = $this->uri->segments(2);
// based on the page_id do something.
$data['somedata'] = 'About us data here';
// this is an actual file loaded from the template view
$data['main_content'] = 'my_about_page';
$this->load->view('template',$data);
}
}
in the template file
$this->load->view('template/header');
$this->load->view('template/nav');
$this->load->view($main_content);
$this->load->view('template/footer');
