The problem with CodeIgniter URI routing and _remap (dynamic)

PHP
1

hello all
Question about CodeIgniter:
to routes for change url of http://localhost/blog/index?id=16/ to http://localhost/blog/16/ add $route[‘blog’] = “index?id=”; but not work address http://localhost/blog/16 and have error:
404 Page Not Found
The page you requested was not found.

why?

2

You cannot use the query string by default in CodeIgniter; check this manual page for more.

thanks
i checked URI Class but don’t understand.
Please tell me where is the problem to post #1?

You need to understand how the controllers work, unless you configure it differently, you will normally have a 2 segment URI.

So, your URI to view a blog post would be /blog/view/16 for example. Blog being the controller and view being a method inside the Blog controller.

i want remowe


?id=

of this url:


http://localhost/blog?id=16

this change to:


http://localhost/blog/16

my .htaccess is:

RewriteEngine on
RewriteCond $1 !^(index\\.php|resources|robots\\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

did must use of routes or .htaccess? what do i do?

6

Read the section called “Enabling Query Strings” in the first link I posted.

7

Stop using the .htaccess altogether for now, then enable query string support in CodeIgniter.

Once you have ?c=blog&id=16 routing to your Blog controller, you can look to tweak your .htaccess to suit.

thanks, i test _remap and work.


function _remap( $method )
	    {
	        // $method contains the second segment of your URI
	        switch( $method )
	        {
	            case 'hello':
	                $this->index();
	                break;
	        }
	    }

with this code, change url

http://localhost/blog

to

http://localhost/blog/hello

how change this code for any dynamic id? and replace $row->subject with hello?

my CI_Controller is:


<?php
class Blog extends CI_Controller {
    function __construct()
	{
		parent::__construct();                
	}
    
    function _remap( $method )
	    {
	        // $method contains the second segment of your URI
	        switch( $method )
	        {
	            case 'hello':
	                $this->index();
	                break;
	        }
	    }
    /**/
	function index()
	{
	    
			    $g_subject = $this->input->get('id', TRUE);		     
			    $query = $this->db->get_where('miniblog', array('id' => $g_subject));
			    foreach ($query->result() as $row)
			    {
				$data = array(
				    'subject' => $row->subject,
				    'title' => $row->title,                
				    'image_path' => $row->image_path,
				    'alt' => $row->alt,
				    'text' => $row->text,
				    'date' => $row->date,
				);
			    }
			     
			     $this->load->view('miniblog/blog', $data);
			     //add customer size to databe on customer
			     
			     //$this->customer_size_model->show();
              
	}
	function ipv6()
	{
	    $this->load->view('miniblog/ipv6');
	}
}
?>
