Add Routes for Action Method in Controller - php

Question

In .NET using AttributeRouting we can add the Route for each Action Method. Something like below
[HttpGet, Route("Create-Project")]
public ActionResult CreateProject()
{
return View();
}
So, in the above code...line 1 indicates that we can mention the route for each Action Method. So url will become something like below..
http://domainname/Create-Project
Question
Is it feasible in PHP MVC CI ? and right now I will have to write the code in route.php in config folder.

Answer 1

In routes.php you can define it
Syntax
$route['short_url_name'] = 'complete/path/for/url';
Example
$route['Contact-Us'] = 'home/contact';
$route['Blog'] = 'home/blog';
$route['Our-Work'] = 'home/work';
so URL look like
http://domain.com/Contact-Us
http://domain.com/Blog
http://domain.com/Our-Work
Codeigniter.com examples

Answer 2

In Application/config/router.php you can add some config like that:
$route['Create-Project'] = 'home/welcome';
So, each time you visit http://domain.com/Create-Project, it will redirect you to http://domain.com/home/welcome

If you are looking for database driven dynamic routes you can rty this, else you can follow what #abdulla has suggested.
Table structure for Dynamic routes(Table name example: routes).
id | slug |route
---------------------------------------------
1 |Pankaj |controller/method/id of user
2 |Abdulla |controller/method/id of user
3 |Niranjan |controller/method/id of user
In controller
$this->load->helper('text');
$slug = $this->input->post("username");// example if you want the username in url as route.
$slug = url_title(convert_accented_characters($slug), 'dash', TRUE);
$slug = $this->Routes_model->validate_slug($slug);
$route['slug'] = $slug;
$route_id = $this->Routes_model->save($route);
$route_id will have the id of route in routes table, insert the route id and slug in users table(For which table you want dynamic routes)
This is the code for route model
<?php
class Routes_Model extends CI_Model {
var $file_name;
function __construct()
{
parent::__construct();
$this->file_name = APPPATH.'config/routes'.EXT;
}
function check_slug($slug, $id=false)
{
if($id)
{
$this->db->where('id !=', $id);
}
$this->db->where('slug', $slug);
return (bool) $this->db->count_all_results('routes');
}
function validate_slug($slug, $id=false, $count=false)
{
if(is_numeric($slug))
{
$slug = '';
$characters = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
for ($i = 0; $i < 3; $i++)
{
$slug .= $characters[rand(0, strlen($characters) - 1)];
}
}
if($this->check_slug($slug.$count, $id))
{
if(!$count)
{
$count = 1;
}
else
{
$count++;
}
return $this->validate_slug($slug, $id, $count);
}
else
{
return $slug.$count;
}
}
function save($route)
{
// print_r($route);exit;
if(!empty($route['id']))
{
$this->db->where('id', $route['id']);
$this->db->update('routes', $route);
return $route['id'];
}
else
{
$this->db->insert('routes', $route);
return $this->db->insert_id();
}
}
}
?>
One condition i have checked is if the username is a number, i ll generate a length of 3 characters in validate_slug().
Now add the following code in core folder by file name MY_Router.php
<?php
class My_Router extends CI_Router
{
function __construct()
{
parent::__construct();
}
// this is here to add an additional layer to the routing system.
//If a route isn't found in the routes config file. then it will scan the database for a matching route.
function _parse_routes()
{
$segments = $this->uri->segments;
$segments = array_splice($segments, -2, 2);
// Turn the segment array into a URI string
$uri = implode('/', $segments);
// Is there a literal match? If so we're done
if (isset($this->routes[$uri]))
{
return $this->_set_request(explode('/', $this->routes[$uri]));
}
// Loop through the route array looking for wild-cards
foreach ($this->routes as $key => $val)
{
// Convert wild-cards to RegEx
$key = str_replace(':any', '.+', str_replace(':num', '[0-9]+', $key));
// Does the RegEx match?
if (preg_match('#^'.$key.'$#', $uri))
{
// Do we have a back-reference?
if (strpos($val, '$') !== FALSE AND strpos($key, '(') !== FALSE)
{
$val = preg_replace('#^'.$key.'$#', $val, $uri);
}
return $this->_set_request(explode('/', $val));
}
}
//look through the database for a route that matches and apply the same logic as above :-)
//load the database connection information
require_once BASEPATH.'database/DB'.EXT;
if(count($segments) == 1)
{
$row = $this->_get_db_route($segments[0]);
if(!empty($row))
{
return $this->_set_request(explode('/', $row['route']));
}
}
else
{
$segments = array_reverse($segments);
//start with the end just to make sure we're not a multi-tiered category or category/product combo before moving to the second segment
//we could stop people from naming products or categories after numbers, but that would be limiting their use.
$row = $this->_get_db_route($segments[0]);
//set a pagination flag. If this is set true in the next if statement we'll know that the first row is segment is possibly a page number
$page_flag = false;
if($row)
{
return $this->_set_request(explode('/', $row['route']));
}
else
{
//this is the second go
$row = $this->_get_db_route($segments[1]);
$page_flag = true;
}
//we have a hit, continue down the path!
if($row)
{
if(!$page_flag)
{
return $this->_set_request(explode('/', $row['route']));
}
else
{
$key = $row['slug'].'/([0-9]+)';
//pages can only be numerical. This could end in a mighty big error!!!!
if (preg_match('#^'.$key.'$#', $uri))
{
$row['route'] = preg_replace('#^'.$key.'$#', $row['route'],$uri);
return $this->_set_request(explode('/', $row['route']));
}
}
}
}
// If we got this far it means we didn't encounter a
// matching route so we'll set the site default route
$this->_set_request($this->uri->segments);
}
function _get_db_route($slug)
{
return DB()->where('slug',$slug)->get('routes')->row_array();
}
}
The above file is very important. As codeigniter first runs files inside core folder, this will create the slug you want. No need to add any routes in routes.php file.
Now while displaying users, you shud echo the slug in your users table.
Lets say controller name is users, method name is edit_user.
your controller code will look like this,
function edit_user($id){
// fetch the data related to $id, and load the view here
}
In url if it sees Niranjan, it will automatically take the route from routes table and will enter your function, edit_user().
Yes Method Looks Lengthy, but works perfect, i use this in all my ecommerce sites.
