将variables二传递给控制器

这是我的控制器代码：

public function search_records() { if($this->session->userdata('logged_in')) { $data = array ( 'employeeName' => $this->input->post('employeeName'), 'userID' => $this->input->post('userID'), 'date' => $this->input->post('date'), 'timeSelect' => $this->input->post('timeSelect'), 'error_message' => 'Sorry there is no record !' ); if($data['employeeName'] !== '' OR $data['userID'] !== '') { if(isset($data['date'])) { if($data['timeSelect'] == 1) { $data['time1'] = '00:00:00'; $data['time2'] = '23:59:00'; $result_from_db= $this->mrecord->search_by_id_or_name_with_date($data); if($result_from_db == false) { $data['show_search_error_message'] = 'Sorry, there is no record !'; $this->load->view('vhome', $data); }else { $data['result_display'] = $result_from_db->result(); $data['row_count'] = count($result_from_db->result()); $this->session->set_userdata("excel_data", $result_from_db->result()); $this->pagi($data); } }else { $data['time1'] = '12:30:00'; $data['time2'] = '15:30:00'; $result_from_db = $this->mrecord->search_by_id_or_name_with_date($data); if($result_from_db == false) { $data['show_search_error_message'] = 'Sorry, there is no record !'; $this->load->view('vhome', $data); }else { $data['result_display'] = $result_from_db->result(); $data['row_count'] = count($result_from_db->result()); $this->session->set_userdata("excel_data", $result_from_db->result()); $this->pagi($data); } } }else { $data['error_message'] = 'Something is wrong ! Please check your date .'; $this->load->view('vhome', $data); } }else if(isset($data['date'])) { if($data['timeSelect'] == 1) { $data['time1'] = '07:00:00'; $data['time2'] = '19:00:00'; $result_from_db = $this->mrecord->search_by_date($data); if($result_from_db == false) { $data['error_message'] = 'Sorry, there is no record !'; $this->load->view('vhome', $data); }else { $data['result_display'] = $result_from_db->result(); $data['row_count'] = count($result_from_db->result()); $this->session->set_userdata("excel_data", $result_from_db->result()); $this->pagi($data); } }else { $data['time1'] = '12:30:00'; $data['time2'] = '15:30:00'; $result_from_db = $this->mrecord->search_by_date($data); if($result_from_db == false) { $data['error_message'] = 'Sorry, there is no record !'; $this->load->view('vhome', $data); }else { $data['result_display'] = $result_from_db->result(); $data['row_count'] = count($result_from_db->result()); $this->session->set_userdata("excel_data", $result_from_db->result()); $this->pagi($data); } } } else { $data['error_message'] = 'Oops ... you can not search without input !'; $this->load->view('vhome', $data); } }else { redirect ('welcome', 'refresh'); } 

这是我的模型：

 public function search_by_id_or_name_with_date($data) { if($data['userID'] == '') { $condition = "employeeName =" . "'" . $data['employeeName'] . "'"; }else { $condition = "employeeID =" . "'" . $data['userID'] . "'"; } $condition2 = "date =" . "'" . $data['date'] . "'"; $condition1 = "time BETWEEN " . "'" . $data['time1'] . "'" . "AND" . "'" . $data['time2'] . "'"; $this->db->select('employeeID, employeeName, departmentName, date, time, tb_inout.doorStatus'); $this->db->from('tb_access_logs'); $this->db->join('tb_inout', 'tb_access_logs.doorID = tb_inout.doorID'); $this->db->where($condition); $this->db->where($condition1); $this->db->where($condition2); $query = $this->db->get(); if ($query->num_rows() > 0) { return $query; } else { return false; } } public function search_by_date($data) { $condition = "date =" . "'" . $data['date'] . "'"; $condition1 = "time BETWEEN " . "'" . $data['time1'] . "'" . "AND" . "'" . $data['time2'] . "'"; $this->db->select('employeeID, employeeName, departmentName, date, time, tb_inout.doorStatus'); $this->db->from('tb_access_logs'); $this->db->join('tb_inout', 'tb_access_logs.doorID = tb_inout.doorID'); $this->db->where($condition); $this->db->where($condition1); $query = $this->db->get(); if($query->num_rows() > 0) { return $query; }else { return false; } } 

这是我的看法：

 <div class="jumbotron"> <?php $this->load->helper('array'); if (isset($result_display)) { echo "<div class=container>"; echo "<h2>Result</h2>"; echo "<p>All result was generated from BioStar Database</p>"; echo "<table class='table table-hover' data-toggle='table' data-show-export='true' data-pagination='true' data-click-to-select='true' data-toolbar='#toolbar' data-url='../json/data1.json'>"; echo "<thead>"; echo "<tr><th>Employee ID</th><th>Employee Name</th><th>Department Name</th><th>Date</th><th>Time</th><th>State</th></tr>"; echo "</thead>"; echo "<tbody>"; foreach ($result_display as $value) { echo '<tr>' . '<td>' . $value->employeeID . '</td>' . '<td>' . $value->employeeName . '</td>' . '<td>' . $value->departmentName . '</td>' . '<td>' . $value->date . '</td>' . '<td>' . $value->time . '</td>' . '<td>' . $value->doorStatus . '</td>' . '</tr>'; } echo "</tbody>"; echo "</table>"; }else { echo '<div class="row">'; echo '<center>' . $error_message . '</center>'; echo '</div>'; $this->output->set_header('refresh:3; url='. base_url("crecord")); } ?> 

这是我的Excel导出控制器：

 class Excel extends CI_Controller { public function index() { $this->load->library('session'); if($this->session->userdata('logged_in')) { redirect('crecord', 'refresh'); }else { redirect('welcome', 'refresh'); } } public function report() { $this->load->helper('download'); $this->load->model('mrecord'); $result_data = $this->session->userdata("excel_data"); $headers = ''; // just creating the var for field headers to append to below $data = ''; // just creating the var for field data to append to below $fields = array('Employee ID', 'Employee Name', 'Department Name', 'Date', 'Time', 'State'); if ($result_data == 0) { echo '<p>The table appears to have no data.</p>'; } else { foreach ($fields as $field) { $headers .= $field . "\t"; } foreach ($result_data as $row) { $line = ''; foreach($row as $value) { if (( ! isset($value)) OR ($value == "")) { $value = "\t"; } else { $value = str_replace('"', '""', $value); $value = '"' . $value . '"' . "\t"; } $line .= $value; } $data .= trim($line)."\n"; } $data = str_replace("\r","",$data); force_download("Report.xls", $headers . "\n" . $data); } 

}}

当我尝试通过select第一个选项导出到Excel时，它是可以的。 但是，当我试图导出第二个选项（仅限date）它不起作用。
