如何在每个页面使用FPDF库显示表头? [英] How to display table header in every page using FPDF library?
问题描述
只需要你的帮助我的代码。
我的问题是如何从上一页获取表头,并在剩余的页面访问它?如果我有一个大数据,我想在每一页也指出头表。
下面是构建表的函数:
函数BuildTable($ header,$ data){
//颜色,线宽和粗体字体
$ this-> SetFillColor(255,255,255) ;
$ this-> SetTextColor(0);
$ this-> SetDrawColor(0,0,0);
$ this-> SetLineWidth(.3);
$ this-> SetFont('Arial','',7);
//标题
//为列宽设置数组
$ this-> SetFillColor(0,0,0);
$ this-> SetTextColor(255);
$ this-> SetDrawColor(0,0,0);
$ this-> SetLineWidth(.3);
$ this-> SetFont('','B');
$ w = array(15,120,30,30); // CHANGE THIS
//将标题发送到PDF文档
for($ i = 0; $ i< count($ header); $ i ++)
$ this-> Cell($ w [$ i],7,$ header [$ i],1,0,'C',1);
$ this-> Ln();
//颜色和字体恢复
$ this-> SetFillColor(255,255,230);
$ this-> SetTextColor(0);
$ this-> SetFont('');
$ this-> SetTextColor(0);
$ fill = false; //用于交替行颜色背景
//这是数据的一部分
foreach($ data as $ row){
$ this-> ; Cell($ w [0],4,$ row [0],'LR',0,'C',$ fill);
$ this-> SetFont('');
$ this-> Cell($ w [1],4,$ row [1],'LR',0,'L',$ fill);
$ this-> SetFont('');
$ this-> Cell($ w [2],4,$ row [2],'LR',0,'R',$ fill);
$ this-> SetFont('');
$ this-> Cell($ w [3],4,$ row [3],'LR',0,'R',$ fill);
$ this-> SetFont('');
$ this-> Ln();
$ fill =! $ fill;
}
$ this-> Cell(array_sum($ w),0,'','T');
$ this-> Ln(50);
$ this-> Ln(50);
}
下面是对PDF类
foreach($ result-> result_array()as $ row){
$ data [] = array
number_format($ row ['total'],2),
, 2),
);
}
$ pdf = new PDF();
$ pdf-> AliasNbPages();
$ header = array('QTY','ITEM / DESCRIPTION','UNIT PRICE','TOTAL AMOUNT');
$ pdf-> SetFont('Arial','',8);
$ pdf-> SetFillColor(255,0,0);
$ pdf-> AddPage('l');
$ pdf-> Ln();
$ pdf = new PDF();
顺便说一句,我还有一个页眉和页脚功能。
在第一行,我需要有39行,不包括表头和第二行,其余的应该是36行。
我如何计算?

根据fpdf教程。
class PDF extends FPDF
{
//页header
function Header()
{
// Logo
$ this-> Image('logo.png',10,6,30);
// Arial bold 15
$ this-> SetFont('Arial','B',15);
//向右移动
$ this-> Cell(80);
//标题
$ this-> Cell(30,10,'Title',1,0,'C');
//换行符
$ this-> Ln(20);
}
//页脚
函数Footer()
{
//位于离底部1.5厘米处
$ this-> ; SetY(-15);
// Arial italic 8
$ this-> SetFont('Arial','I',8);
//页码
$ this-> Cell(0,10,'Page'。$ this-> PageNo()。'/ {nb}',0,0,'C' );
}
}
//继承类的实例
$ pdf = new PDF();
$ pdf-> AliasNbPages();
$ pdf-> AddPage();
$ pdf-> SetFont('Times','',12);
for($ i = 1; $ i <= 40; $ i ++)
$ pdf-> Cell(0,10,'Printing line number'。$ i,0,1);
$ pdf-> Output();
just need your help with my code. My question is how can I get the table header from the previous page and access it on the remaining pages? If I have a large data I want to indicate also the header table in every page. But I don't have an idea how to do it.
Here's the function that build the table:
function BuildTable($header,$data) {
//Colors, line width and bold font
$this->SetFillColor(255,255,255);
$this->SetTextColor(0);
$this->SetDrawColor(0,0,0);
$this->SetLineWidth(.3);
$this->SetFont('Arial','',7);
//Header
// make an array for the column widths
$this->SetFillColor(0,0,0);
$this->SetTextColor(255);
$this->SetDrawColor(0,0,0);
$this->SetLineWidth(.3);
$this->SetFont('','B');
$w = array(15,120,30,30); //CHANGE THIS
// send the headers to the PDF document
for($i = 0; $i < count($header); $i++)
$this->Cell($w[$i],7,$header[$i],1,0,'C',1);
$this->Ln();
//Color and font restoration
$this->SetFillColor(255,255,230);
$this->SetTextColor(0);
$this->SetFont('');
$this->SetTextColor(0);
$fill = false; // used to alternate row color backgrounds
//HERE'S THE PART THAT LOOPS THE DATA
foreach($data as $row){
$this->Cell($w[0],4,$row[0],'LR',0,'C',$fill);
$this->SetFont('');
$this->Cell($w[1],4,$row[1],'LR',0,'L',$fill);
$this->SetFont('');
$this->Cell($w[2],4,$row[2],'LR',0,'R',$fill);
$this->SetFont('');
$this->Cell($w[3],4,$row[3],'LR',0,'R',$fill);
$this->SetFont('');
$this->Ln();
$fill =! $fill;
}
$this->Cell(array_sum($w),0,'','T');
$this->Ln(50);
$this->Ln(50);
}
Below is the call for PDF class
foreach($result->result_array() as $row){
$data[] = array($row['item_qty'],
$row['itemname'],
number_format($row['item_price'],2),
number_format($row['total'],2),
);
}
$pdf = new PDF();
$pdf->AliasNbPages();
$header = array('QTY','ITEM / DESCRIPTION' , 'UNIT PRICE', 'TOTAL AMOUNT');
$pdf->SetFont('Arial','',8);
$pdf->SetFillColor(255,0,0);
$pdf->AddPage('l');
$pdf->Ln();
$pdf = new PDF();
By the way I have also a header and footer function. In first row I need to have 39 rows excluding the table header and the second row and also the remaining should 36 rows.
How can I compute that? Where should I need a computation for that?
Please help me guys thanks.
According to fpdf tutorial.
class PDF extends FPDF
{
// Page header
function Header()
{
// Logo
$this->Image('logo.png',10,6,30);
// Arial bold 15
$this->SetFont('Arial','B',15);
// Move to the right
$this->Cell(80);
// Title
$this->Cell(30,10,'Title',1,0,'C');
// Line break
$this->Ln(20);
}
// Page footer
function Footer()
{
// Position at 1.5 cm from bottom
$this->SetY(-15);
// Arial italic 8
$this->SetFont('Arial','I',8);
// Page number
$this->Cell(0,10,'Page '.$this->PageNo().'/{nb}',0,0,'C');
}
}
// Instanciation of inherited class
$pdf = new PDF();
$pdf->AliasNbPages();
$pdf->AddPage();
$pdf->SetFont('Times','',12);
for($i=1;$i<=40;$i++)
$pdf->Cell(0,10,'Printing line number '.$i,0,1);
$pdf->Output();
