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billyear。我不想显示表中的值。
我想显示在页面的顶部。我怎样才能做到这一点？任何建议？提前致谢。干杯。

<?php 

    session_start(); 
    require('fpdf/fpdf.php');

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

    $result=mysql_query("SELECT r.hosteladmissionno,

Answer 1

添加到您的代码行$Y_Table_Position = 46和线路$pdf->Cell(15,50,'Anna University Hostels');之间，它会在你的页面的右上角显示“学期，月，年”灰色（改变学期，月，年用自己的真实的值） 。

//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); 

正如你看到的，我去X = 160，Y = 0，并创建所需的文字，自定义字体和颜色，在那之后，我改变颜色为黑色（东阳我的默认字体颜色的新细胞是白色的）并且去X = 16，Y = 8因此您的“安娜大学旅舍”在同一个位置被印刷。之后，你会像以前一样打印表格。

希望我没有提到你的问题，这就是你要找的。 （如果不发表评论:)）

Answer 2

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

Answer 3

设置你在头文件中提到的东西。

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'); 
    ... 
    ... 
}
