问题描述

嗨，大家好，我正在尝试修改pdf文件并将其存储在我的服务器中，但是我一直收到此错误： FPDF error: Some data has already been output, can't send PDF file ，我无法设法确定原因。

这是PHP脚本： 

<?php
ob_start();

$ANNEE = date('Y');
$TIME = date("h:i:s");

db_connect.php 

<?php
include_once 'sql-config.php'; // file contening db credentials
$mysqli = new mysqli(HOST, USER, PASSWORD, DATABASE);
$mysqli->query("SET CHARACTER SET utf8");

//message d'erreur en cas d'échec

}

有人知道这是从哪里来的吗？

再次查看脚本后，您似乎可能在创建多个PDF文件，但仅输出最后一个。

我认为include和FPDF实例应该在foreach之外，例如： 

require_once('../fpdf17/fpdf.php');
require_once('../FPDI/fpdi.php');

$pdf = new FPDI();

foreach($destinataireFR as $destinataireFR) { 
    $mail->Body = "<p style='font-family:Calibri'>Bonjour,<br/><br/><a href='$destinataireFR[lien]' style='font-size:1.1em'>Cliquez ici</a> pour ouvrir le fichier <b>$rapportFR</b>.<br/><br/>Cordialement,<br/><br/><b style='color:#4271BE'>L'Equipe Horizon Soft Commodities</b><br/>01.49.89.46.16<br/><a href='mailto:analyse@horizon-sc.fr'>analyse@horizon-sc.fr</a><br/><br/><br/><p style='font-size:0.8em'>Si vous souhaitez vous d&eacute;sinscrire et ne plus recevoir ces messages, <a href='mailto:analyse@horizon-sc.fr &subject=Desinscription'>cliquez ici</a>.</p><br/>$messageAdditionel</p>";
    $mail->Subject = "$rapportFR";
    $mail->AddAddress("$destinataireFR[mail]");
    if($categ == 27)
    {
        // add a page
        $pdf->AddPage();
        // set the source file
        $pdf->setSourceFile($dirFR . "/" . $pdfFR);
        // import page 1
        $tplIdx = $pdf->importPage(1);
        // use the imported page and place it at point 0,0 with a width of 300 mm(pour un centrage comme reel)
        $pdf->useTemplate($tplIdx, 0, 0, 300);
        $pdf->SetXY(70, 70);
        $pdf->Write(0, "test");
        $pdf->SetXY(100, 80);
        $pdf->Write(0, "test");  
    }
if ($mail->Send()){
    // echo "success<br/>"; 
}else{
    // echo "fail : ". $mail->ErrorInfo . "<br/>";
}
$mail->ClearAddresses();
}
$pdf->Output();

在打开和关闭php标签后立即添加这些功能。 

<?php 
ob_start();
// php code here
ob_end_flush(); 
?>
