 Maybe Can I fix your code? I pagnation  
 admin code  
  public restaurant_listing () {$ restaurant = $ this- & gt; Uri-> Segment (4); I use this code for; $ Limit_ti = 20; If (! $ Restaurant): offset_ti = 0; Other: $ offset_ti = $ restaurant; end if; $ This- & gt; Load-> Model ('restaurant_model'); // call model $ - this-> Load-> Library ('pagination'); // call library $ query = $ this- & gt; Restaurant_model- & gt; Logical ($ limit_ti, $ offset_ti); // An article $ total_page = $ this- & gt; Restaurant_model- & gt; Record_count (); // Calculation line / ** endorsement ** / $ config ['base_url'] = base_url (). 'Admin / restaurant / restaurant_listing'; $ Config ['total_rows'] = $ total_page- & gt; Num_rows (); $ Config ['per_page'] = 20; $ Config ['uri_segment'] = 4; $ Config ['num_links'] = 10; $ Config ['use_page_numbers'] = true; $ Config ['cur_tag_open'] = '& lt; B & gt; '; $ Config ['cur_tag_close'] = '& lt; / B & gt; '; $ This- & gt; Pagination-> Start ($ config); $ Data = array ('query' = & gt; $ query, 'page' = & gt; $ restaurant); $ Data ['content'] = 'admin / restaurant_listing'; $ This- & gt; Load-> View ('template', $ data); }   
 Model code  
  restlisting function ($ border, $ offset) {$ query = $ this- & gt; Db- & gt; Query ($ offset from $ name * * $ ID limit to ID ASC, $ limit "); Return $ query; } Function record_count () {$ query = $ this- & gt; Db- & gt; Query ("name * to * name *"); Return $ query; }
