how can send variable value through pagination links? - codeigniter

Question

SOLVED
I was trying to create pagination on the home page.
my default controller :
$route['default_controller'] ="home";
problem 1:
for pagination if I write-
$config['base_url'] = base_url() . 'home/index'; // index function
$config['uri_segment'] = 3;
$config['per_page'] = 10;
$limit = array($config['per_page'] => $this->uri->segment(3));
then it works but it shows 'localhost/baseurl/home/index/10' on browser address bar.I want to show just 'localhost/baseurl/10' (while 'localhost/baseurl/' is my homepage and I want pagination on there).so I wrote
$config['base_url'] = base_url(); // index function
$config['uri_segment'] = 1;
$config['per_page'] = 10;
$limitt = array($config['per_page'] => $this->uri->segment(1));
but that doesn't work. how can I do that ?
problem 2:
how can I send a variable value through pagination link like
localhost/baseurl/home/index?search=y/10
I wrote:
$config['base_url'] = base_url() . 'home/index?search=y';
but this doesn't work. it receives search=y/10. not only y and the pagination doesn't find 10 on $this->uri->segment(3))
so whats the correct way to do that?
Edit:
my htaccess code is:-
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./mysite/index.php [L]
</IfModule>
this code shows my site address like 'localhost/mysite/'. but if I set the base url of the pagination like
$config['base_url'] = base_url();
$config['uri_segment'] = 1;
$config['per_page'] = 10;
$limitt = array($config['per_page'] => $this->uri->segment(1));
then the number shows on pagination link like 'localhost/mysite/10' but the value '10' not received by the script. if I write-
$config['base_url'] = base_url().'home/index'; // 'index' is the function in 'home' class
$config['uri_segment'] = 3;
$config['per_page'] = 10;
$limitt = array($config['per_page'] => $this->uri->segment(3));
then it works but the browser address line becomes 'localhost/mysite/home/index/10' what I don't like. whats the way to solve the first problem ?

Answer 1

For the first problem you will have to define a rewrite rule as in the first comment.
For the second problem do like this,
if($this->uri->segment(3)){
$keyword = $this->uri->segment(3);
}
else if($this->input->get('search')){
$keyword = $this->input->get('search');
}
$config['base_url'] = base_url().'home/index/'.$keyword.'/page/';
$config["uri_segment"] = 5;
