在 Codeigniter 上生成多页 TCPDF

Question

我有一个 table 用于显示数据并根据每一行生成报告。 table 会是这样的：

-----------------------------------------------------------------------------------------
|   employee_name  |   division   |   period   |   allowance  |  download   |  checkbox   |
|       tony       | advertising  | august 2018|    15.00     |(downloadbtn)|(checkboxbtn)|
|       lola       | advertising  | august 2018|    20.00     |(downloadbtn)|(checkboxbtn)|
-----------------------------------------------------------------------------------------

到目前为止，这是我生成 pdf 的控制器：

<?php
class AllowanceReport extends CI_Controller{
    function __construct(){
        parent::__construct();
        $this->load->model('allowance_m');
    }

    public function index(){
        $this->load->view('allowance_v');
    }

    public function reportpdf($id){
        ob_start();
            $allowance= $this->allowance_m->get_allowance_byid($id);
            $this->load->library('pdf_surat');
            $pdf = new
            PDF_SURAT('P','mm','A4',true,'UTF-8',false);
            $pdf->AddPage();

            $pdf->setXY(12,40);
            $txt_pembuka = 'Allowance Report';
            //$pdf->SetFontSize(16);
            $pdf->SetFont('times', 'B', 16, '', 'false');
            $pdf->MultiCell(0, 5, $txt_pembuka, 0, 'C', 0, 2, '', '', true);

            $pdf->setXY(20,$pdf->getY()+7);
            $pdf->SetFont('times', '', 12, '', 'false');
            $pdf->cell(35,5,"Nama");
            $pdf->cell(0,5,":   ".$allowance->employee_name);

            $pdf->setXY(20,$pdf->getY()+7);
            $pdf->cell(35,5,"Periode");
            $periode = strtotime($allowance->periode);
            $formatperiode = date('F Y',$periode);
            $pdf->cell(0,5,":   ".$formatperiode);

            $pdf->setXY(20,$pdf->getY()+7);
            $pdf->cell(35,5,"Uang Makan");
            $pdf->cell(0,5,":   Rp.".$allowance->allowance);
            $pdf->Output();

        ob_end_flush();
        }

    }
?>

这是视图：

<div class="table">
        <table class="table table-striped table-bordered table-hover">
                <thead>
                    <tr>
                        <th><center>Employee Name</center></th>
                        <th><center>Division</center></th>
                        <th><center>Period</center></th>
                        <th><center>Allowance</center></th>
                        <th><center>Download</center></th>
                        <th><center><input type="checkbox" class="checkAll" /></center></th>
                        <?php } ?>
                    </tr>
                </thead>

                <?php 
                    $no = 1;
                    if(is_array($query)){
                    foreach($query as $row):
                    ?>
                    <tr>
                        <td><?php echo $row->employee_name ?></td>
                        <td><?php echo $row->division ?></td>
                        <td><?php echo date("F-Y", strtotime($row->period)) ?></td>
                        <td><?php echo $row->allowance ?></td>
                        <td>
                            <center>
                                <a href="<?php echo base_url(). "index.php/allowancereport/reportpdf/".$row->idallowance;?>" class="btn btn-success" id="cetaksurat_"><b><span class="glyphicon glyphicon-download"></span></b></a>
                            </center>
                        </td>
                        <td>
                            <center>
                                <input type="checkbox" class="checkitem" value="<?php echo $row->idmakan; ?>"/>
                            </center>
                        </td>
                        <td>
                            <center>
                                <a href="<?php echo base_url();?>absengaji/edit/<?php echo $row->idmakan;?>" class="btn btn-primary btn-xs edit" data-toggle="modal" id="edit_">
                                <span class="glyphicon glyphicon-pencil"></span></a>
                            </center>
                        </td>
                    <?php } ?>
                    </tr>
                <?php endforeach ; } ?>         
                </table>
        </div>
        </div>
    </div>
</div>

这是我的模型

        public function get_allowance_byid($id)
    {
        $sql = "SELECT * FROM allowance WHERE idallowance='".$id."'";
        return $this->db->query($sql)->row();
    }

我设法为每一行生成了一个 pdf。但是是否可以根据选中的复选框生成包含多个页面的文件？ pdf文件是否可以生成每个数据，并在文件中的不同页面进行检查？

Answer 1

你可以像下面那样做

前端

在table标签前后添加表单标签，将表单目标设置为新方法（allreportpdf），同时添加提交按钮触发全部保存report inside the form (maybe before the form close tag) :

<form action="<?php echo base_url() . "index.php/allowancereport/allreportpdf" ?>" method="POST" role="form">
    <table class="table table-striped table-bordered table-hover">
    ...
    ...
    ...
    </table>
    <button type="submit" class="btn btn-primary">Get All Report</button>
</form>

在复选框输入上添加一个名称（可能是 eid），它将用作新方法（allreportpdf）上的 post 数据。

<center>
    <input type="checkbox" class="checkitem" name="eid[]" value="<?php echo $row->idmakan; ?>"/>
</center>

后端

由于这个页面使用不同的布局，你应该在AllowanceReportclass上创建一个新方法，使用之前设置的post名称（eid），你可以在 foreach() 循环中使用它，并修改 pdf 设置，使每个 id 在每个页面上分开：

public function allreportpdf(){
    ob_start();
    $this->load->library('pdf_surat');
    $pdf = new
    PDF_SURAT('P','mm','A4',true,'UTF-8',false);
    foreach ($this->input->post('eid') as $id) {
        $allowance= $this->allowance_m->get_allowance_byid($id);
        $pdf->AddPage();

        $pdf->setXY(12,40);
        $txt_pembuka = 'Allowance Report';
        //$pdf->SetFontSize(16);
        $pdf->SetFont('times', 'B', 16, '', 'false');
        $pdf->MultiCell(0, 5, $txt_pembuka, 0, 'C', 0, 2, '', '', true);

        $pdf->setXY(20,$pdf->getY()+7);
        $pdf->SetFont('times', '', 12, '', 'false');
        $pdf->cell(35,5,"Nama");
        $pdf->cell(0,5,":   ".$allowance->employee_name);

        $pdf->setXY(20,$pdf->getY()+7);
        $pdf->cell(35,5,"Periode");
        $periode = strtotime($allowance->periode);
        $formatperiode = date('F Y',$periode);
        $pdf->cell(0,5,":   ".$formatperiode);

        $pdf->setXY(20,$pdf->getY()+7);
        $pdf->cell(35,5,"Uang Makan");
        $pdf->cell(0,5,":   Rp.".$allowance->allowance);
    }
    $pdf->output();

    ob_end_flush();
}
