Pagination Class Changes

[eluser]imn.codeartist[/eluser]
If you have enabled Query string at the config and still you want to use the NON Enabled Query string parameters for the pagination then here you need to do some alteration in the Pagination class at system/libraries/Pagination

Find below code in function create_links()

Code:

// Determine the current page number.        
$CI =& get_instance();

Code:

/* Comment here

if ($CI->config->item('enable_query_strings') === TRUE OR $this->page_query_string === TRUE)
        {
            if ($CI->input->get($this->query_string_segment) != 0)
            {
                $this->cur_page = $CI->input->get($this->query_string_segment);
                
                // Prep the current page - no funny business!
                $this->cur_page = (int) $this->cur_page;
            }
        }
        else
        {
to here
*/
            if ($CI->uri->segment($this->uri_segment) != 0)
            {
                $this->cur_page = $CI->uri->segment($this->uri_segment);
                
                // Prep the current page - no funny business!
                $this->cur_page = (int) $this->cur_page;
            }
/* comment here*///}

        $this->num_links = (int)$this->num_links;

again find

Code:

// Calculate the start and end numbers. These determine
        // which number to start and end the digit links with
        $start = (($this->cur_page - $this->num_links) > 0) ? $this->cur_page - ($this->num_links - 1) : 1;
        $end   = (($this->cur_page + $this->num_links) < $num_pages) ? $this->cur_page + $this->num_links : $num_pages;

        // Is pagination being used over GET or POST?  If get, add a per_page query
        // string. If post, add a trailing slash to the base URL if needed

Code:

/*
Comment Here
if ($CI->config->item('enable_query_strings') === TRUE OR $this->page_query_string === TRUE)
        {
            $this->base_url = rtrim($this->base_url).'&'.$this->query_string_segment.'=';
        }
        else
        { to here */
            $this->base_url = rtrim($this->base_url, '/') .'/';
/* and here */    //}

Now you are done.

Thanks!

Dixanta, this is great. It works as expected.

Please keep in mind tho that it's never a good idea to edit the core files. What I've done here is simply create a library file called MY_Pagination.php inside the /application/libraries folder.

Inside that file, I put this code - which is your modified version of the code (minus the commented areas).

Code:

<?php
class MY_Pagination extends CI_Pagination {

    function MY_Pagination()
    {
        parent::CI_Pagination();
    }
    
    function create_links()
    {
        // If our item count or per-page total is zero there is no need to continue.
        if ($this->total_rows == 0 OR $this->per_page == 0)
        {
            return '';
        }

        // Calculate the total number of pages
        $num_pages = ceil($this->total_rows / $this->per_page);

        // Is there only one page? Hm... nothing more to do here then.
        if ($num_pages == 1)
        {
            return '';
        }

        // Determine the current page number.
        $CI =& get_instance();

            if ($CI->uri->segment($this->uri_segment) != 0)
            {
                $this->cur_page = $CI->uri->segment($this->uri_segment);

                // Prep the current page - no funny business!
                $this->cur_page = (int) $this->cur_page;
            }
    
        $this->num_links = (int)$this->num_links;

        if ($this->num_links < 1)
        {
            show_error('Your number of links must be a positive number.');
        }

        if ( ! is_numeric($this->cur_page))
        {
            $this->cur_page = 0;
        }

        // Is the page number beyond the result range?
        // If so we show the last page
        if ($this->cur_page > $this->total_rows)
        {
            $this->cur_page = ($num_pages - 1) * $this->per_page;
        }

        $uri_page_number = $this->cur_page;
        $this->cur_page = floor(($this->cur_page/$this->per_page) + 1);

        // Calculate the start and end numbers. These determine
        // which number to start and end the digit links with
        $start = (($this->cur_page - $this->num_links) > 0) ? $this->cur_page - ($this->num_links - 1) : 1;
        $end   = (($this->cur_page + $this->num_links) < $num_pages) ? $this->cur_page + $this->num_links : $num_pages;

        // Is pagination being used over GET or POST?  If get, add a per_page query
        // string. If post, add a trailing slash to the base URL if needed
            $this->base_url = rtrim($this->base_url, '/') .'/';

          // And here we go...
        $output = '';

        // Render the "First" link
        if  ($this->cur_page > ($this->num_links + 1))
        {
            $output .= $this->first_tag_open.'<a >base_url.'">'.$this->first_link.'</a>'.$this->first_tag_close;
        }

        // Render the "previous" link
        if  ($this->cur_page != 1)
        {
            $i = $uri_page_number - $this->per_page;
            if ($i == 0) $i = '';
            $output .= $this->prev_tag_open.'<a >base_url.$i.'">'.$this->prev_link.'</a>'.$this->prev_tag_close;
        }

        // Write the digit links
        for ($loop = $start -1; $loop <= $end; $loop++)
        {
            $i = ($loop * $this->per_page) - $this->per_page;

            if ($i >= 0)
            {
                if ($this->cur_page == $loop)
                {
                    $output .= $this->cur_tag_open.$loop.$this->cur_tag_close; // Current page
                }
                else
                {
                    $n = ($i == 0) ? '' : $i;
                    $output .= $this->num_tag_open.'<a >base_url.$n.'">'.$loop.'</a>'.$this->num_tag_close;
                }
            }
        }

        // Render the "next" link
        if ($this->cur_page < $num_pages)
        {
            $output .= $this->next_tag_open.'<a >base_url.($this->cur_page * $this->per_page).'">'.$this->next_link.'</a>'.$this->next_tag_close;
        }

        // Render the "Last" link
        if (($this->cur_page + $this->num_links) < $num_pages)
        {
            $i = (($num_pages * $this->per_page) - $this->per_page);
            $output .= $this->last_tag_open.'<a >base_url.$i.'">'.$this->last_link.'</a>'.$this->last_tag_close;
        }

        // Kill double slashes.  Note: Sometimes we can end up with a double slash
        // in the penultimate link so we'll kill all double slashes.
        $output = preg_replace("#([^:])//+#", "\\1/", $output);

        // Add the wrapper HTML if exists
        $output = $this->full_tag_open.$output.$this->full_tag_close;

        return $output;
    }
}

As noted here in the User Guide, the function create_links() will override the core pagination create_links() function. Should you upgrade the core files in the future, your sites pagination won't break.
