在 FPDF 中显示值

Question

这是我在 php 中使用 FPDF 生成 pdf 的代码。我想在 PDF 文件中显示学期、账单月份和账单年份。我不想显示表中的值。
我想显示在页面顶部。我该怎么做？有什么建议吗？提前致谢。干杯。

<?php

    session_start();

    //Connect to your database

    $r1=$_SESSION['sem1'];

    if(!$con)
    {
    die('Unable to connect'.mysql_error());
    }
    mysql_select_db('hostel',$con);

    $result=mysql_query("SELECT r.hosteladmissionno,
           r.student_name,
           r.semester,

Answer 1

为什么不使用 FPDF 的标准“header()”扩展函数？
http://fpdf.org/en/doc/header.htm

Answer 2

将其添加到行 $Y_Table_Position = 46 和行 $pdf->Cell(15,50,'Anna University Hostels'); 之间的代码中，它将显示“学期、月、年”页面右上角的灰色（将学期、月、年更改为其实际值）。

    //Fields Name position
    $Y_Fields_Name_position = 40;
    //Table position, under Fields Name
    $Y_Table_Position = 46;
// ABOVE IS YOUR ORIGINAL CODE, ADD The FOLOWING LINES

    $pdf->SetXY(160,0);
    $pdf->SetFont('Times','B',6);
    $pdf->SetTextColor('139','140','142');
    $pdf->Cell(5,15,'Semester,Month,Year',0,0,'L');

    $pdf->SetTextColor('0','0','0');
    $pdf->SetXY(16,8);

// CONTINUE WITH ORIGINAL CODE
    $pdf->Cell(15,50,'Anna University Hostels');
    //First create each Field Name
    //Gray color filling each Field Name box
    $pdf->SetFillColor(232,232,232);

如您所见，我转到 X=160，Y=0 并使用所需的文本、自定义字体和颜色创建一个新单元格，之后，我将颜色更改为黑色（因为我的默认字体颜色是白色）并转到 X =16,Y=8 所以你的“Anna University Hostels”打印在相同的位置。之后，您的表格将像以前一样被打印。

希望我理解你的问题，这就是你正在寻找的。 （如果没有留下评论:)）

Answer 3

在标题函数中设置您谈到的内容。

function header()
{
     $this->SetFont('whatever the font u like','B',23)//I just randomly set fonts
     $this->Cell(30,10,'$_POST['user_id']',0,0,'C');
     ...
     ...
}
