在所有FPDF页面中添加子标题

好了，我的问题解决了。对于任何正在寻找类似东西的人，以下是我所做的:GetY()函数返回该行的Y位置，因此当它是页面的第一行时，此值将为0(或常数，取决于您的布局)。我刚刚做了:

foreach ($sql as $key => $value) 
{
    if ($pdf->GetY() == 0)
    {
        $pdf->SetFont('Arial', 'B', $font_size);
        $pdf->Ln(2 * $line_height);
        $pdf->Cell(20, $line_height, 'Number', '', '', 'L');
        $pdf->Cell(120, $line_height, 'Product', '', '', 'L');
        $pdf->Cell(40, $line_height, 'Ammount', '', '', 'L');
        $pdf->Cell(40, $line_height, 'Value ($)', '', '', 'L');
    }
    $pdf->SetFont('Arial', 'B', $font_size);
    $pdf->Ln(2 * $line_height);
    $pdf->Cell(20, $line_height, $value['sale_id'], '', '', 'L');
    $pdf->Cell(120, $line_height, $value['product'], '', '', 'L');
    $pdf->Cell(40, $line_height, $value['ammount'], '', '', 'L');
    $pdf->Cell(40, $line_height, $value['value'], '', '', 'L');
}

谢谢大家!

在你的类中重写FPDF的header()方法。

class PDF extends FPDF
{
    public function Header() {
        $this->Cell(0, 8, "HEADER TEXT", 0, 0, 'R');
    }
}

在添加新页面时，FPDF将自动调用。

我在试图为每个页面添加标题时遇到了同样的问题。这也连接到MySql数据库。以下是我最终成功的方法。
