我想以表格形式显示来自MySQL数据库的数据。当数据超过第一页时,下一行将在下一页正确写入。但是之后的每一行都被写入新页面。这意味着第一页看起来很好,但第二页和更高页只包含一行。我怎么能阻止这个?以下是我的代码:
<?php
require('fpdf17/fpdf.php');
require('db.php');
//create a FPDF object
$pdf=new FPDF();
//set font for the entire document
$pdf->SetFont('Times','B',20); //set font for the whole page (font family, style, size)
$pdf->SetTextColor(0,0,0); //using RGB value
//set up a page
$pdf->AddPage('P'); //potrait orientation
$pdf->SetDisplayMode('default'); //using 100 percent zoom and the viewer's default layout
//insert an image
$icon = "files/icon.png";
$pdf->Cell (10);
$pdf->Cell(60, 60, $pdf->Image($icon, $pdf->GetX(), $pdf->GetY(), 33.78), 0, 0, 'L', false);
$pdf->SetFillColor(0,0,0);
$pdf->SetFont('Times', '', 12);
$pdf->SetXY(10, 30);
$pdf->Cell(10);
$pdf->Cell(30, 6, 'Retrieval Date' , 0, 0, '', 0);
date_default_timezone_set("Asia/Kuala_Lumpur"); //set default time zone
$pdf->Cell(30, 6, ': '.date("d/m/Y"), 0, 2, 'B', 0);
//Set x and y position for the main text, reduce font size and write content
$pdf->SetXY(20,40); //setting the position
$pdf->SetFont('Times', 'BU', 14);
$pdf->Write(12,'Absenteeism record for:');
$fac = addslashes( filter_input( INPUT_GET,'fac',FILTER_SANITIZE_STRING ) );
$data = "SELECT * FROM faculty WHERE fac_code LIKE '$_GET[fac]'";
$result = $conn->query($data) or die("Error: ".mysqli_error($conn));
while($ser=mysqli_fetch_array($result)){
$fac_name = $ser['fac_name'];
$pdf->SetFillColor(0,0,0);
$pdf->SetFont('Times', '', 12);
$pdf->SetY(50);
$pdf->Cell(10);
$pdf->SetX(20);
$pdf->Cell(30, 6, 'FACULTY' , 0, 0, '', 0);
$pdf->Cell(30, 6, ': '.$fac.'-'.' '.$fac_name, 0, 2, 'B', 0);
}
//start first table
$pdf->SetFillColor(255,255,255);
$pdf->SetFont('Times', 'B', 12);
$pdf->SetXY(21,58);
$pdf->Cell(10, 6, 'No.', 1, 0, 'L', 1);

$pdf->Cell(20, 6, 'Course', 1, 0, 'L', 1);
$pdf->Cell(35, 6, 'Absenteeism %', 1, 0, 'L', 1);
$row_height = 6;
$y1_axis = 58;
$y1_axis = $y1_axis + $row_height;
$counter = 1;
$fac = addslashes( filter_input( INPUT_GET,'fac',FILTER_SANITIZE_STRING ) );
$data = "

答案 0 :(得分:1)
我怀疑原因是你的$y1_axis
变得太大了;可能最简单的解决方案是添加到数据库循环的底部:
$y1_axis = $y1_axis + $row_height;
$counter++;
if ($counter % 35 === 0) {
$pdf->AddPage();
$y1_axis = 20;
}
并确保在创建PDF时使用$pdf->SetAutoPageBreak(false)
禁用自动分页符。
