我正在尝试在我的应用程序中的选定记录上应用删除功能。问题是记录显示在分页中，即3,4行，我能够从第一页删除记录，但当我移动到第二页并选择几个记录时，删除记录按钮不起作用。任何adivise都会有所帮助。 我正在寻找回复 这是我的列表代码
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);
}
我的删除功能代码是
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存在小错误
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'];
..............
}
