我的第一个 php 问题...

我正在使用 fpdf 生成 pdf 文件。我正在做的网站的原始版本在打印输出上使用了通用图像。我想将其更改为基于 id 的图像。

我的问题是在检索 ID 的查询运行之前声明了带有图像的标题。这可能很容易解决，但不是零 php-exp...

这是我的代码：

<?php
require('fpdf.php');
import_request_variables("GP", "rvar_");

$prn_con = mysql_connect('localhost', 'root', '');
mysql_select_db('db');

class PDF extends FPDF{
    function Header(){
        $this->Image('../../images/logo_generic.gif',170,8,30);
        }
    }

$pdf=new PDF();
$pdf->Open();
$tok = strtok($rvar_bestellkeys,",");

while ($tok){
    $result = mysql_query('SELECT * FROM bk WHERE bestellkey = "'.$tok.'"');
    $i = 0; 
    $fCount = mysql_num_fields($result);
    while($row=mysql_fetch_row($result)){
        while ($i < $fCount){
            $fName = mysql_field_name($result, $i); 
            $$fName = trim($row[$i]);
            $i++; 
            $strcont = strlen ($$fName);
            }
            $i=0; 
    }

查询结果之一是我要包含在 header() 徽标路径中的 ID。

问题：
如何从我的内部设置 header() 路径while-loop？循环打印出文档（单页/多页），每个页面的右上角都应该有徽标。

感谢帮助！

编辑：
这是整个 php 脚本：

<?php
require('fpdf.php');
import_request_variables("GP", "rvar_");

$prn_con = mysql_connect('localhost', 'root', '');
mysql_select_db('db');

$resultsprache = mysql_query("SELECT * FROM sprachen WHERE sprache = '".$rvar_sprache."'");
while($row=mysql_fetch_row($resultsprache)){
    $fName = trim($row[2]);
    $$fName = trim($row[3]);
    }

$FileN = $tx_bestellung. '_'.date("YmdHis").'.pdf';
$title = $tx_bestellung;

class PDF extends FPDF{
    function Header(){
        $this->Image('../../images/logo_klein.gif',170,8,30);
        }
    }

 $pdf=new PDF();
 $pdf->Open();

 $pdf->SetFont('Arial','',8);

 $tok = strtok($rvar_bestellkeys,",");

    $result = mysql_query('SELECT * FROM bK WHERE bestellkey = "'.$tok.'"');
    $i = 0; 
    $fCount = mysql_num_fields($result);
    while($row=mysql_fetch_row($result)){

            $$fName = trim($row[$i]);
            $i++; 
            $strcont = strlen ($$fName);
            }
        $i=0; 
    }

if($tok != ""){

快速且很脏，但应该可以：

    <?php
    require('fpdf.php');
    import_request_variables("GP", "rvar_");

    $prn_con = mysql_connect('localhost', 'root', '');
    mysql_select_db('db');

    $resultsprache = mysql_query("SELECT * FROM sprachen WHERE sprache = '".$rvar_sprache."'");
    while($row=mysql_fetch_row($resultsprache)){
        $fName = trim($row[2]);
        $$fName = trim($row[3]);
        }

    $FileN = $tx_bestellung. '_'.date("YmdHis").'.pdf';
    $title = $tx_bestellung;

    $tok = strtok($rvar_bestellkeys,",");

    while ($tok){
        $result = mysql_query('SELECT * FROM bK WHERE bestellkey = "'.$tok.'"');
        $i = 0; 
        $fCount = mysql_num_fields($result);
        while($row=mysql_fetch_row($result)){

            if ($something === true) {
                $my_magic_id = $row['my_magic_id_column'];
            }

            if (isset($my_magic_id) && !class_exists('PDF')) {
                class PDF extends FPDF{
