CI分页参数不断追加到base_url

Question

I am implementing a list of rows with pagination using CodeIgniter. The problem is it keeps appending &page=n everytime I click on next page.

for example, initially if my URL is like

http://example.com/search/?a=1&b=2&page=1

and when I click on page two, it becomes

http://example.com/search/?a=1&b=2&page=1&page=2

I tried playing with configs but doesn't seem to be working properly. Is that something to do with base_url ? should I dynamically create base_url string without last parameter &page=n ? I thought it would automatically re-write it.

pagination configs are as follows.

$page_config['base_url'] = $this->config->item('app_root') . $_SERVER['REQUEST_URI'];
$page_config['total_rows'] = $result['total'];
$page_config['per_page'] = 10;
$page_config['page_query_string'] = TRUE;
$page_config['query_string_segment'] = 'page';
$page_config['use_page_numbers'] = TRUE;

Thoughts?

Answer 1

Please Add base_url this type

http://example.com/search/?a=1&b=2
$page_config['base_url'] = http://example.com/search/?a=1&b=2;

Answer 2

This is incorrect

$page_config['base_url'] = $this->config->item('app_root') . $_SERVER['REQUEST_URI'];

Codeigniter pagination add &page=n with the config['base_url']
But your base_url change each time at different page

$page_config['base_url']='http://example.com/search/?a=1&b=2';//for first time and codeigniter added $page=1
$page_config['base_url']='http://example.com/search/?a=1&b=2&page=1';//for 2nd time and codeigniter added $page=2
$page_config['base_url']='http://example.com/search/?a=1&b=2&page=1&page=2';//for 3rd time and codeigniter added $page=3

Your base url should be fixed and not be dynamic. It should be

$page_config['base_url']='http://example.com/search/?a=1&b=2';

you can do it like this but its bad

$page_config['base_url'] = $this->config->item('app_root') . str_replace("&page=".$_GET['page'],"",$_SERVER['REQUEST_URI']);
