我使用fpdf在php（codeigniter）中创建pdf文档。要打印的数据已出现在谷歌浏览器的pdf预览中。但是当数据以pdf文档格式保存时，数据不会出现

pdf preview in google chrome

in adobe reader this is my code: 

public function laporan()
{
    $bulan1 = $this->input->post('bulan1');
    $bulan2 = $this->input->post('bulan2');
    $tanggal = array(
        'tanggal1'=>$bulan1,
        'tanggal2'=>$bulan2
    );

    $query  = "SELECT costumers.nama AS costumer, alats.nama AS alat, DATE(transaksis.tanggal_ambil) AS tanggal_ambil,DATE(transaksis.tanggal_kembali) AS tanggal_kembali FROM costumers,transaksis,alats WHERE costumers.id=transaksis.costumer_id AND transaksis.alat_id=alats.id AND DATE(transaksis.created_at) BETWEEN '$bulan1' AND '$bulan2' ORDER BY transaksis.created_at DESC";
    $data   = $this->UserModel->query_umum($query)->result();
    $header = array(
        array("label"=>"No", "length"=>8, "align"=>"L"),
        array("label"=>"Peminjam", "length"=>50, "align"=>"L"),
        array("label"=>"Nama Alat", "length"=>60, "align"=>"L"),
        array("label"=>"Tanggal Kirim", "length"=>30, "align"=>"L"),
        array("label"=>"Tanggal Pengembalian", "length"=>40, "align"=>"L")
    );

    $this->cetak_laporan($header,$data,$tanggal);
}

public function cetak_laporan($header,$data,$tanggal)
{
    $laporan = new FPDF();
    $laporan->AddPage();
    $laporan->SetFont('Arial','B',12);
    $laporan->Image(base_url('asset/img/logo-dewiratih.png'),5,4,30,10);

            $i++;

我检查了你的一切都很好:)（google chrome，adobbe reader，foxit reader）。

检查我的代码：

public function laporan()
    {
        $bulan1  = $this->input->post('bulan1');
        $bulan2  = $this->input->post('bulan2');
        $tanggal = array(
            'tanggal1' => '1111',
            'tanggal2' => '2222',
        );

        $data = [];
        for ($i = 0; $i <= 3; $i++) {
            for ($i2 = 0; $i2 <= 3; $i2++) {
                $data[$i][$i2] = random_string('alnum', 5);
            }
        }

        $header = array(
            array("label" => "No", "length" => 8, "align" => "L"),
            array("label" => "Peminjam", "length" => 50, "align" => "L"),
            array("label" => "Nama Alat", "length" => 60, "align" => "L"),
            array("label" => "Tanggal Kirim", "length" => 30, "align" => "L"),
            array("label" => "Tanggal Pengembalian", "length" => 40, "align" => "L"),
        );

        $this->cetak_laporan($header, $data, $tanggal);
    }

    public function cetak_laporan($header, $data, $tanggal)
    {
        $laporan = new FPDF();
        $laporan->AddPage();
        $laporan->SetFont('Arial', 'B', 12);

        $laporan->Output("Laporan Peminjaman.pdf", "I");
    }

答案 1 :(得分：1)

如果您希望在用户可以选择下载文档之前先显示该文档，那么您应该考虑使用GET作为查询字符串而不是POST方法$bulan1＆amp; $bulan2。

当您从上一页预览pdf文档时，它实际上会发送您的POST变量（$bulan1＆amp; $bulan2），但是当您保存它时，浏览器只是如果请求中没有POST数据，则可以在保存的文档中看到它遗漏了$bulan1＆amp; $bulan2值。
