Question

我要做的是使用FPDF创建并通过电子邮件发送多个PDF文件。我已经将所有内容都发送到单个文件，但是当我尝试将所有内容都放到循环中时，脚本最终只输出PDF的第一个实例，然后退出到空白屏幕。当我只处理一条记录时，这运行得很好，但是当你添加多条记录时，它只运行一次。我真的无法弄清楚这里要做的是我的代码。任何协助或指示都表示赞赏。

while ($data = mysql_fetch_row($query)) // under normal circumstances working properly
    {
        $clientid = $data['0'];
        if($clientid)
        {
            require("generatepdf.php"); //styles the pdf and is working properly
            $savepath = 'c:/ledgers/'.$cname.' Cash Ledger.pdf';
            $pdf->Output($savepath,'F');
            require("ledgeremail.php"); //runs query to get email address and emails the outputted file 
        }
    }

以下是我的pdf生成代码的要点，遗漏了这一代的具体细节。

<?php

require("includes/pdf/fpdf.php");


{

$pdf = new FPDF( );
$pdf->AddPage();
$pdf->SetFont('Arial','',16);

    //Run Query to get Ledger information for the $clientid variable
            //Pass information from query into the different variables throughout script



            //Print Document Title
            $pdf->Cell(0,10,$cname.' Petty Cash Ledger', 0,1,'L');
            //Print First Month Grouping
            $pdf->SetFont('Arial','',10);
            $pdf->Line($linestart,$pdf->GetY(),$lineend,$pdf->GetY());
            $pdf->Cell(10,5,$startmonth.", ".$startyear, 0,0,'L');
            $pdf->SetX(175);

您的方法是正确的，但您可能需要重新构建逻辑。

在您包含的每个文件中，您可能希望编写与生成PDF和发送电子邮件相关的功能。然后你的循环可以重做，看起来像这样：

require("generatepdf.php"); 
require("ledgeremail.php");

while ($data = mysql_fetch_row($query)) // under normal circumstances working properly
{
    $clientid = $data['0'];
    if($clientid)
    {
        $cname = generate_pdf_for_client( $clientid ); // calls a function in generatepdf.php
        $savepath = 'c:/ledgers/'.$cname.' Cash Ledger.pdf';
        $pdf->Output($savepath,'F');
        send_email_to_client(some appropriate parameters); // calls a function in ledgeremail.php
    }
}

因此，在您的文件中，您需要为建议的generate_pdf_for_client和send_email_to_client函数实现逻辑。
