Php 在Codeigniter上生成多页TCPDF

我有一个表，用于显示数据并基于每一行生成报告。该表如下所示：

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

这是我目前生成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();
        }

    }
?>

我设法为每一行生成一个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文件能否生成一个文件中使用不同页面检查的每个数据？

您可以像下面这样做

前端

在表标记之前和之后添加表单标记，将表单目标设置为新方法（

allreportpdf

），并添加submit按钮以触发表单内部的save all report（可能在表单关闭标记之前）：

后端

由于此页面使用不同的布局，您应该在

AllowanceReport

类上使用以前设置的帖子名称（

eid

）创建一个新方法，您可以在

foreach（）

循环中使用它，并修改pdf设置，以便在每个页面上分离每个id：

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();
}

已经试过了，但是上面写着：

Message:foreach（）提供的参数无效

？确实需要您的帮助尝试在foreach之前添加这一行：

print\r（$this->input->post（'eid'）；模具（），那么输出是什么？它给了我26，最后一个选中行的id号我想我犯了一个错误，尝试在每个复选框输入名称后加上大括号，从
name=“eid”
到
name=“eid[]”
        public function get_allowance_byid($id)
    {
        $sql = "SELECT * FROM allowance WHERE idallowance='".$id."'";
        return $this->db->query($sql)->row();
    }

<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>

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

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();
}
