【问题描述】:
好吧,首先要做的事情:
我已经在这个网站上搜索了 6 个多小时,并且一直得到相同的结果。我不断得到的主要答案是:How to Generate Barcode using PHP and Display it as an Image on the same page
但这对我不起作用。即使该页面上被接受的答案也以“添加所有代码后,您将得到这种方式:”结尾,这太模糊了,我觉得我应该已经是理解它的专家了。我对这个问题感到沮丧,因为我似乎找不到任何“白痴方向”来帮助我理解这个库中的一切是如何工作的,用于 php 的条形码生成器。
这是我所拥有的:
我正在使用 fpdf 打印一个效果很好的 pdf 文件!
页面名称:PrintMyPDF.php
<?php
//error_reporting(E_ALL);
//ini_set('display_errors', 1);
$thisorderID = $_GET['Xort'];
require ('UFunctions.php');
if (trim($thisorderID) == ""){
$value = '0';
}
if (!is_digit($thisorderID) || $thisorderID < 0)
{
header('Location:ErrorInt.php');
exit;
}
//Database connection established
require_once('DBASEConnector.php');
$sql2 = "SELECT users.name, users.storenum, users.storename, Orders.OrderID, Orders.name
FROM users, Orders
WHERE Orders.name = users.name
AND Orders.OrderID = '$thisorderID'";
$result = $db->query($sql2);
$row = $result->fetch_assoc();
$ThisStoreNum = $row['storenum'];
$ThisStoreName = $row['storename'];
require('fpdf.php');
$pdf = new FPDF();
//$fpdf->SetMargins(0, 0, 0);
//$fpdf->SetAutoPageBreak(true, 0);
$pdf->SetAuthor('Walter Ballsbig');
$pdf->SetTitle('Order Form');
$pdf->SetFont('Helvetica','B',16);
$pdf->SetTextColor(0,0,0);
$pdf->AddPage('P');
$pdf->SetDisplayMode(real,'default');
$pdf->SetXY(50,20);
$pdf->SetDrawColor(0,0,0);
$pdf->Cell(100,10,'Order Form',1,1,'C',0);
$pdf->SetFontSize(10);
$pdf->SetX(50);
$pdf->Cell(100,10, 'Order: '.$thisorderID.' | Store: '.$ThisStoreNum.'-'.$ThisStoreName,1,1,'C',0);
$pdf->SetXY(10,50);
$pdf->SetFontSize(12);
$pdf->Cell(6,6,'X',1,0,'C',0);
$pdf->Cell(14,6,'QTY',1,0,'C',0);
$pdf->Cell(130,6, 'ITEM',1,0,'C',0);
$pdf->Cell(30,6, 'UNIT',1,1,'C',0);
$query = "SELECT Inventory.ProductI, Inventory.ProductName, Inventory.CurrentQty, Inventory.Pull, Inventory.Unit, OrderItems.ProductI, OrderItems.QtyO, OrderItems.OrderI
FROM Inventory, OrderItems
WHERE OrderItems.OrderI = '$thisorderID'
AND OrderItems.ProductI = Inventory.ProductI
ORDER BY Inventory.Pull, Inventory.ProductName";
$result = $db->query($query);
$num_results = $result->num_rows;
for ($i=0; $i <$num_results; $i++)
{
$row = $result->fetch_assoc();
$pdf->SetFontSize(12);
IF ($row['CurrentQty'] <=0)
{
$pdf->SetFontSize(10);
$pdf->Cell(6,6,'BO',1,0,'C',0);
$pdf->SetFontSize(12);
}else{
$pdf->Cell(6,6,' ',1,0,'C',0);
}
$pdf->Cell(14,6, $row['QtyO'],1,0,'C',0);
$pdf->Cell(130,6, $row['ProductName'],1,0,'L',0);
$pdf->Cell(30,6, $row['Unit'],1,1,'C',0);
}
$pdf->Output();
$db->close();
?>
这将我的 pdf 打印得很漂亮!现在我想在页面上添加一个条形码,代表订单号以供扫描。
现在这是我的代码,其中包含条形码...代码。
条码页面名称:BarCodeIt.php
<?php
function BarCodeIt($MyID) {
// Including all required classes
require_once('./class/BCGFontFile.php');
require_once('./class/BCGColor.php');
require_once('./class/BCGDrawing.php');
// Including the barcode technology
require_once('./class/BCGcode39.barcode.php');
// Loading Font
$font = new BCGFontFile('./font/Arial.ttf', 18);
// Don't forget to sanitize user inputs
$text = isset($_GET['text']) ? $_GET['text'] : $MyID;
// The arguments are R, G, B for color.
$color_black = new BCGColor(0, 0, 0);
$color_white = new BCGColor(255, 255, 255);
$drawException = null;
try {
$code = new BCGcode39();
$code->setScale(2); // Resolution
$code->setThickness(30); // Thickness
$code->setForegroundColor($color_black); // Color of bars
$code->setBackgroundColor($color_white); // Color of spaces
$code->setFont($font); // Font (or 0)
$code->parse($text); // Text
} catch(Exception $exception) {
$drawException = $exception;
}
/* Here is the list of the arguments
1 - Filename (empty : display on screen)
2 - Background color */
$drawing = new BCGDrawing('', $color_white);
if($drawException) {
$drawing->drawException($drawException);
} else {
$drawing->setBarcode($code);
$drawing->draw();
}
//Header that says it is an image (remove it if you save the barcode to a file)
header('Content-Type: image/png');
header('Content-Disposition: inline; filename="barcode.png"');
// Draw (or save) the image into PNG format.
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);
}
?>
现在在我的 PDF 文件中,就在这一行之前:
$pdf->Output();
我已经添加了这个:
$pdf->AddPage('P');
$pdf->SetDisplayMode(real,'default');
require('/BarCodeIt.php');
$MyBarCode = BarCodeIt($thisorderID);
echo $MyBarCode;
但它所做的是我所有的其他 pdf 元素都消失了,我只剩下一个大条形码(右边的那个!那部分有效),但这就是屏幕上的全部内容。就像条形码部分运行时它会否定其他所有内容并仅打印条形码。我只想在 PDF 上我想要的地方打印条形码,但我不够聪明,无法弄清楚我做错了什么。对此的任何帮助将不胜感激。
