Question

我在生成PDF的项目上使用CodeIgniter。它在单个PDF中工作一次，但现在我尝试了另一个错误。这是代码：

class Checkout extends CI_Controller {
    public function __construct(){
        parent::__construct();
        $this->load->model('PurchaserModel', 'purchaser');
            .... 
        $this->load->library('M_pdf');
    }

    public function save(){
        ..... 
        $data['orders'] = $this->order->get_order_details($logged_in_id);
        if($data['orders']){
            $details = $this->purchaser->get_purchaser_details($this->session->userdata['logged_in']['username']);
            $data['details'] = convertvalue($details);
            $order_id = $data['orders'][0]['order_id'];
            $data['order_id'] = $order_id;
        }
        // 1st PDF work fine if the other generate PDF is commented out
        $purchaser_sheet_html = $this->load->view('pdf/purchaser_sheet', $data, true);
        $purchaser_sheet_html2 = $this->load->view('pdf/purchaser_sheet_page_2', $data, true);
        $pdf1 = $this->m_pdf->load();
        $pdfFilePath1 = uniqid(rand(), true);
        $pdfFilePath = "purchase-order-summary-".date('Ymdhis')."-".$pdfFilePath1.".pdf";
        $pdf1->WriteHTML($purchaser_sheet_html);
        $pdf1->AddPage();
        $pdf1->WriteHTML($purchaser_sheet_html2);
        $pdf1->Output("./uploads/".$pdfFilePath, "F"); // this is line 425 and got error 

        // 2nd PDF when this code is up, it got an error
        $construction_sheet_summary = $this->load->view('pdf/construction_sheet_summary', $data, true);
        $pdf2 = $this->m_pdf->load();
        $pdfFilePath2 = uniqid(rand(), true);
        $pdfFilePath_2 = "construction-sheet-summary-".date('Ymdhis')."-".$pdfFilePath2.".pdf";
        $pdf2->WriteHTML($construction_sheet_summary); // this is line 433 and got error 
        $pdf2->Output("./uploads/".$pdfFilePath_2, "F");

        $this->db->update($this->db->dbprefix('order'), array('purchaser_sheet' => $pdfFilePath, 'construction_sheet' => $pdfFilePath_2), array('ID' => $insert_id));
        $email_settings = $this->settings->email_settings();

    }

这是完整的错误消息：

我尝试调试代码，发现这一行出现了isseu

$construction_sheet_summary = $this->load->view('pdf/construction_sheet_summary', $data, true);

我construction_sheet_summary.php存在，我试图删除该文件上的所有php代码，但遇到相同的错误。

有人知道我的案子吗？

Answer 1

按照@Viney在评论中的建议，使用composer升级到（最好是）mPDF的最新版本-这将解决依赖关系和each()弃用警告。

找不到类“ MpdfException”
