我使用默认的codeiginter分页库。我尝试在之前创建的页面中实现此功能,该页面显示了所有空缺,但由于我们在网站上获得了很多空间,因此性能非常糟糕。这就是我在这个页面上需要分页的原因。请注意,这不是最干净的解决方案,有一条新的轨道可以检修整个页面并从头开始。这是一个快速的&肮脏的解决方案,因为我们需要让它在我们的实时环境中工作,直到返工完成。
这是我的控制器代码:
public function overviewVacancies($city = null)
{
$this->is_logged_in();
// Load Models
$this->load->model('vacancy/vacancies_model');
$this->load->model('perk/interests_model');
$this->load->model('perk/engagement_model');
$this->load->model('user/userSavedVacancies_model');
// Passing Variables
$data['title'] = lang("page_title_activities_overview");
$data['description'] = lang('meta_desc_activities');
$data['class'] = 'vacancy';
$data['engagements'] = $this->engagement_model->getAll();
$data['interests'] = $this->interests_model->getAllInterests();
$data['bread'] = $this->breadcrumbmanager->getDashboardBreadcrumb($this->namemanager->getDashboardBreadName("0"), $this->namemanager->getDashboardBreadName("1"));
$data['tasks'] = $this->interests_model->getAllTasks();
// Set session data
$this->session->set_userdata('previous',"http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]");
$this->session->set_userdata('previous-title', "1");
$filterdata = array(
'interests' => $this->input->post('interests'),
'skills' => $this->input->post('skills'),
'fulldate' => $this->input->post('daterange'),
'location' => $this->input->post('location'),
'city' => $this->input->post('sublocality_level_1'),
'capital' => $this->input->post('locality')
);
if (!empty($filterdata['interests'])) {
$filterdata['interests'] = rtrim($filterdata['interests'], ";");
$filterdata['interests'] = str_replace(' ', '', $filterdata['interests']);
$filterdata['interests'] = str_replace(';', ',', $filterdata['interests']);
}
if (!empty($filterdata['skills'])) {
$filterdata['skills'] = str_replace(' ', '', $filterdata['skills']);
$filterdata['skills'] = explode(",", $filterdata['skills']);
}
//Manually clear the commune and city variables if the location was empty
if (empty($filterdata['location'])) {
$filterdata['city'] = '';
$filterdata['capital'] = '';
}
if($city == null){
$orgId = $this->organization_model->getOrgIdByName(LOCATION);
}
else{
$orgId = $this->organization_model->getOrgIdByName($city);
$data['bread'] = $this->breadcrumbmanager->getLocalBreadcrumb($this->namemanager->getDashboardBreadName("0"), $city, $data['title'], $data['vacancydetails']);
}
//Set the location to the subdomain automatically (e.g. when the link is clicked) so the activities of that subdomain only show up
if (!empty(LOCATION)) {
$data['title'] = sprintf(lang('page_title_local_activities'), ucwords(LOCATION));
$data['description'] = sprintf(lang('meta_desc_local_activities'), ucwords(LOCATION));
$filterdata['location'] = LOCATION;
$data['bgcolor'] = $this->localSettings_model->getBgColorHexValueForOrgId($orgId->org_id);
}
if (!empty($filterdata['fulldate'])) {
$splitfromandto = explode(" - ", $filterdata['fulldate']);
$filterdata['datefrom'] = $splitfromandto[0];
$filterdata['dateto'] = $splitfromandto[1];
} else {
$filterdata['datefrom'] = null;
$filterdata['dateto'] = null;
}
//Put these variables in the data variable so we can prefill our filters again with the previous values
//This is necessary because we don't use AJAX yet
$data['filterdata'] = $filterdata;
//Pagination : We do it here so we can re-use the filter query to count all our results
$this->load->library('pagination');
$data['all_vacancies'] = $this->vacancies_model->getFilteredVacancies($filterdata);
$pagconfig['base_url'] = base_url().VACANCY_OVERVIEW;
$pagconfig['total_rows'] = count($data['all_vacancies']);
$pagconfig['per_page'] = 1;
$pagconfig['uri_segment'] = 2;
$pagconfig['use_page_numbers'] = TRUE;
$this->pagination->initialize($pagconfig);
$data['links'] = $this->pagination->create_links();
$start = max(0, ( $this->uri->segment(2) -1 ) * $pagconfig['per_page']);
//This variable contains all the data necessary for a vacancy to be displayed on the vacancy overview page
$data['vacancies'] = $this->vacancies_model->getFilteredVacancies($filterdata, false, null, false, null, false, false, $pagconfig['per_page'], $start);
// Template declaration
$partials = array('head' => '_master/header/head', 'navigation' => '_master/header/navigation_dashboard', 'content' => 'dashboard/vacancy/overview', 'footer' => '_master/footer/footer');
$data['vacancygrid'] = $this->load->view('dashboard/vacancy/vacancygrid', $data, TRUE);
$this->template->load('_master/master', $partials, $data);
}
正如您在代码中看到的,我保留了一个名为$ filterdata的变量,它包含了我们过滤器中使用的所有数据,因为我们在这个版本中没有使用AJAX,我们需要每次都将它传递给视图再次填写并呈现给访客。 但是,使用分页会中断,因为它只是重新加载我的控制器方法,因此$ filterdata中的值会丢失。
我该如何解决这个问题?
注意:它不一定是一个干净的解决方案,它只需要工作,因为无论如何这个页面将在几周后离线。
提前多多感谢!
