Javascript PHP Codeigniter和Ajax中的颜色、价格和大小过滤器

第1节

我在“显示10条记录中的1-5条”中遇到问题。我有一段代码，它只在第一页工作，当我点击第二页时，它会显示相同的结果“显示10条记录中的1-5条”，而不是“显示10条记录中的10条”

控制器中的代码

 $total=$config["total_rows"];
        $per_page=$config['per_page'];
        $curpage=floor(($this->uri->segment(1)/$config['per_page']) + 1);
        $result_start = ($curpage - 1) * $per_page + 1;
        if ($result_start == 0) $result_start= 1; // *it happens only for the first run*
        $result_end = $result_start+$per_page-1;

        if ($result_end < $per_page)   // happens when records less than per page  
        { $result_end = $per_page; } 
        else if ($result_end > $total)  // happens when result end is greater than total records  
        { $result_end = $total;}
        $data['show']="displaying $result_start to $result_end of $total";

public function index($page=1)
    {
         $config = array();
         $keyword    = $this->input->post('search');
        if ($keyword === null){ $keyword = $this->session->userdata('search');}
        else{ $this->session->set_userdata('search',$keyword);}
        $config["base_url"] = base_url();
        $config["total_rows"] = $this->crt->total_items($keyword);
        $config['use_page_numbers'] =true;

        $config['cur_tag_open'] = '<a class="page-numbers current">';
        $config['cur_tag_close'] = '</a>';
        $config["per_page"] =5;
        $config["uri_segment"] = 1;
        $this->pagination->initialize($config);
        $page = ($page - 1) * $config['per_page'];
        // showing x to y of z records
        $total=$config["total_rows"];
        $per_page=$config['per_page'];
        $curpage=floor(($this->uri->segment(1)/$config['per_page']) + 1);
        $result_start = ($curpage - 1) * $per_page + 1;
        if ($result_start == 0) $result_start= 1; // *it happens only for the first run*
        $result_end = $result_start+$per_page-1;

        if ($result_end < $per_page)   // happens when records less than per page  
        { $result_end = $per_page; } 
        else if ($result_end > $total)  // happens when result end is greater than total records  
        { $result_end = $total;}
        $data['show']="displaying $result_start to $result_end of $total";
        $data['sidebar']=$this->crt->sidebar_cat();
        $data['products']=$this->crt->get_product($config["per_page"], $page,$keyword);
        $data["links"] = $this->pagination->create_links();
        $this->load->view('header');
        $this->load->view('index',$data);
        $this->load->view('footer');
    }

至

$curpage=$this->uri->segment(1);
        if ($result_start == 0 || $result_start<0) $result_start= 1; // 

$curpage=$this->uri->segment（1）；
如果（$result_start==0 | |$result_start初始化分页配置时，尝试使用
$config[base_url]
中的控制器/方法，并从
$this->uri->segment（3）获取页码
答案是，所有详细信息和代码都发布在提到的链接问题中。
但我不需要
$this->uri->segment（3）
我将其分为1段。第一段代表控制器，第二段代表方法，其他部分为参数。我将相应地设置路线，并将其分为1段，它工作正常，请重新阅读该问题。这不是我想要的，请重新阅读该问题。请提供答案的主要部分。请参阅
$curpage=floor(($this->uri->segment(1)/$config['per_page']) + 1);
        if ($result_start == 0) $result_start= 1; //

$curpage=$this->uri->segment(1);
        if ($result_start == 0 || $result_start<0) $result_start= 1; // 

function clr(){
           var selected = new Array();
           var size = new Array();
           var url="<?php echo base_url('Cart/filt_color');?>";
          // alert(url);
              $("input:checkbox[name=color]:checked").each(function() {
                  selected.push($(this).val());
                  //console.log(selected);
              });
            // Sizes 
             $("input:checkbox[name=size]:checked").each(function() {
                  size.push($(this).val());
                  //console.log(selected);
              });


              $.ajax({
                  url:url,
                  method:"post",
                  data:{'colors':selected,'sizes':size},
                  success:function(data)
          {
//            
              //console.log(data);
              $("#mdv").html(data);

          }

              });
