FPDF无法从表外部显示数据库中的数据

Question

我正在表的外部和内部显示数据。当我尝试在表内部调用数据时，它可以正常工作，但是当我在表外部调用数据时，它突然不显示。这部分就在这里...

$pdf->MultiCell(194,4,"STORM SURGE INFORMATION",0,'C', false);
$pdf->Cell(191,4,"STORM SURGE: WARNING # ",0,0,'C');
$pdf->Cell(-136,4,$fetch['warning'],0,1,'C');

$pdf->Cell(172,4,"FOR: TYPHOON ",0,0,'C');
$pdf->Cell(-119,4,$fetch['typhoon'],0,1,'C');

$pdf->Cell(175,4,"ISSUED AT ",0,0,'C');
$pdf->Cell(-135,4,$fetch['date'],0,1,'C');

我的PDF当前看起来像这样。

有人可以帮我弄清楚我的代码有什么错误或遗漏吗？

<?php

require("con.php");

$sql="SELECT * FROM table ORDER BY ssh REGEXP '^[^A-Za-z0-9]' ASC, ssh DESC";

$records=mysql_query($sql);
$fetch = $records[0];

require("library/fpdf.php");

class PDF extends FPDF{
  function Header(){
  }
  function Footer(){
  }
}

$pdf = new PDF('p', 'mm', 'Legal');
$title = 'Storm Surge Warning';
$pdf->SetTitle($title);
$pdf->AliasNbPages('{pages}');
$pdf->SetAutoPageBreak(true,40);

$pdf->AddPage();
$pdf->Ln();

$pdf->SetFont('Arial', 'B', 10);

$pdf->MultiCell(194,4,"STORM SURGE INFORMATION",0,'C', false);
$pdf->Cell(191,4,"STORM SURGE: WARNING # ",0,0,'C');
$pdf->Cell(-136,4,$fetch['warning'],0,1,'C');

$pdf->Cell(172,4,"FOR: TYPHOON ",0,0,'C');
$pdf->Cell(-119,4,$fetch['typhoon'],0,1,'C');

$pdf->Cell(175,4,"ISSUED AT ",0,0,'C');
$pdf->Cell(-135,4,$fetch['date'],0,1,'C');

$pdf->Ln(1);

$pdf->SetBorders(array('LT', 'LT', 'LT', 'LT', 'TLR'));
$pdf->SetWidths(array(25, 27, 35, 54, 53));
$pdf->SetAligns(array('C', 'C', 'C', 'L', 'L'));

$pdf->SetFont('Arial', 'B', 10);

$pdf->Row(array("SS Height",
            "Provinces",
            "Low Lying Coastal Areas in the Municipalities of:",
            "IMPACTS",
            "ADVICE/Actions to Take"), 1);

$pdf->SetFont('Arial', '', 11);


while($row = mysql_fetch_array($records)){
  $pdf->Row(array($row['ssh'],
  $row['provi'],
  $row['muni'],
  $row['impact'],
  $row['advice']), 1);
  }

$pdf->SetBorders(array('T', 'T', 'T', 'T', 'T'));
$pdf->Row(array('','','','',''), 1, false, 1);

$pdf->OutPut();
?>

在代码中，您正在获取一行数据，但是在开始while循环之前，您并没有将包含该数据的行添加到PDF中。在设置字体之后，在while循环之前，立即添加如下所示的$pdf->Row位。

$pdf->MultiCell(194,4,"STORM SURGE INFORMATION",0,'C', false); 
$pdf->Cell(191,4,"STORM SURGE: WARNING # ",0,0,'C'); 
$pdf->Cell(-136,4,$fetch['warning'],0,1,'C'); 
$pdf->Cell(172,4,"FOR: TYPHOON ",0,0,'C'); 
$pdf->Cell(-119,4,$fetch['typhoon'],0,1,'C'); 
$pdf->Cell(175,4,"ISSUED AT ",0,0,'C'); 
$pdf->Cell(-135,4,$fetch['date'],0,1,'C');

$pdf->SetFont('Arial', '', 11);

$pdf->Row(array($fetch['ssh'],
    $fetch['provi'],
    $fetch['muni'],
    $fetch['impact'],
    $fetch['advice']), 1);

while($row = mysql_fetch_array($records)){
  $pdf->Row(array($row['ssh'],
  $row['provi'],
  $row['muni'],
  $row['impact'],
  $row['advice']), 1);
}
