我正在尝试对我的应用程序中的选定记录应用删除功能。问题是记录显示在分页中，即 3,4 行，我可以从第一页删除记录，但是当我移动到第二页并选择几条记录时，删除记录按钮不起作用。任何建议都会有帮助。我在这里寻找答复是我的清单代码

public function index($offset=0)
{
    if ( $this->session->userdata('u_name') == FALSE ) 
    {
         $data['page_title']="Admin Login";
         redirect('admin/login',"refresh",$data);
    }   
    $this->load->model('candidate_model');
    $limit=4;       
    $results=$this->candidate_model->get_all_Candidate($limit,$offset);
    $data['candidates']=$results['rows'];
    $offset = $this->uri->segment(3, 0);

    $data['num_results']=$results['num_rows'];
    $this->load->library('pagination');

    $config=array();
    $config['first_url'] = 'candidateList/index';
    $config['base_url']=site_url('candidateList/index');
    $config['total_rows']=$data['num_results'];

    $config['per_page']=$limit;
    $config['uri_segment']=3;
    $config['first_link'] = '>';
    $config['first_tag_open'] = '<div>';
    $config['first_tag_close'] = '</div>';
    $this->pagination->initialize($config);

    $data['page_title']="Candidate List";



    $this->load->view('manageCandidate',$data);
}

我的删除功能代码如下

if($this->input->post('Delete')=='Delete')
        {
            for($i=0;$i<count($_POST['checkbox']);$i++)
            { 

                $candidate_id = $_POST['checkbox'][$i]; 
                $this->candidate_model->deleteCandidate($candidate_id);
                $this->session->set_flashdata('deleteSelected','Selected Candidate has been deleted.');

            }

            $data['page_title']="Candidate List";   
            redirect('candidateList',$data);


        }

删除功能在这里：

public function candidate()
    {

        if ( $this->session->userdata('u_name') == FALSE ) 
        {
             $data['page_title']="Admin Login";
             redirect('admin/login',"refresh",$data);
        }

        $checkList=$this->input->post('checkbox');
        $this->load->model('candidate_model');  

        if($checkList!=NULL)
        {

            if($this->input->post('Delete')=='Delete')
            {
                for($i=0;$i<count($_POST['checkbox']);$i++)
                { 

                    $candidate_id = $_POST['checkbox'][$i]; 
                    $this->candidate_model->deleteCandidate($candidate_id);
                    $this->session->set_flashdata('deleteSelected','Selected Candidate has been deleted.');

                }

                $data['page_title']="Candidate List";   
                redirect('candidateList',$data);


            }
            else if($this->input->post('Email')=='Email')
            {
                for($i=0;$i<count($_POST['checkbox']);$i++)
                { 

                    $admin_id = $_POST['checkbox'][$i];
                    $email_to[$i] = $_POST['checkbox'][$i];
                    $data['email_to'] = $email_to;

                }

                $data['page_title']='Send Mail';
                $this->load->view('admin/sendmail4',$data);
            }
        }
        else
        {
            $this->session->set_flashdata('deleteSelect','Please Select at-least one Candidate.');
            $data['page_title']="Candidate List";
            redirect('candidateList',$data);
        }



    }

您的分页代码偏移值中存在小错误，请更正它

public function index($offset=0)
{
    if ( $this->session->userdata('u_name') == FALSE ) 
    {
         $data['page_title']="Admin Login";
         redirect('admin/login',"refresh",$data);
    }

    $this->load->model('candidate_model');
    $limit=4;     

    //whenever you are calling this pagination  offset value you need to fetch it from URL
    $offset_url = $offset = $this->uri->segment(3, 0);

    //if it's not exist take the default value
    $offset = is_numeric($offset_url)?$offset_url:$offset;

    $results=$this->candidate_model->get_all_Candidate($limit,$offset);
    $data['candidates']=$results['rows'];


    ..............
