如何使用TCPDF制作包含2D条形码的2x6张标签,而不使用列或第三方类?

标签: php mysql tcpdf labels

三个星期(我想我的速度慢了!)我已经尝试使用TCPDF自己的示例以及本网站上的一些建议来弄清楚如何使用数据库记录。当其他人询问如何使用第三方补丁(类)来解决问题时,Asuni先生已经回应了一些求助请求,只是在没有这些类的情况下可以在TCPDF中完成。无论出于何种原因(也许是我自己的误解),我都无法使用TCPDF来使用他的列方法打印标签。

我也不愿意放弃TCPDF而转而采用其他可能的解决方案(我赢得的原因)。 PHP TCPDF Export for Standard Address Labels是通过切换到fpdf17获得所需功能时在此处提出/解决的问题示例。

所以我一直坚持到今天,甚至尝试用法语写的一些精彩的代码,但我无法说服它创建我需要的结构。

因为像我上面提到的那些问题已被"击中"在这么多次(在这个网站和其他地方)没有看似解决方案我决定尽我所能,工作代码,直到我睡眼惺and,测试,重新测试和测试更多。

我终于找到了一种从数据库制作PDF的方法,该数据库将以AVERY 5164格式制作包含6个标签(2个横向,3个向下)的页面的PDF。我没有使用TCPDF或任何第三方补丁或类的列方法就能够做到这一点。

如果他们密切关注我代码中变量的含义,那么任何人都应该能够根据自己的需要改变我的解决方案。

我的积极性必须有更优雅(和正确!)的方式来获得我所做的结果,所以我非常愿意接受有关如何改进我的代码的建议。

而且,在我被烧毁之前,是的,我知道数据库调用需要是PDO。我坚持使用我的客户端允许我访问的内容。

最后,只是想知道制作不同数量记录的各种PDF需要多长时间: 12条记录(2页) - > 4秒下载激活 200条记录 - > 44秒 文件大小合理(我没有写下来,但是......对不起!)

这是我的解决方案[注意:我的数据库连接文件是由于明显原因未在下面给出的包含]:

$colname_year = "-1";
if (isset($_GET['year'])) {
  $colname_year = $_GET['year'];
}

我希望通过改变代码来消除敏感信息,我没有做任何事情。 感谢一个伟大的网站 - 我已经学到了很多东西,并希望现在可以帮助别人了!

看看我的解决方案 - 它可以打印24个标签 - 3 * 8到A4。 只需对宽度,高度和$ qty进行简单的更改,你就可以得到2 * 6.

<?php

include("dbconfig.php");

require_once('../tcpdf/tcpdf.php');
// include 1D barcode class (search for installation path)
require_once('../tcpdf/tcpdf_barcodes_1d.php');

date_default_timezone_set('Asia/Kolkata');


// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, 'mm', 'A4', true, 'UTF-8', false);

// set document information
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('Casual Creators');
$pdf->SetTitle('Bar Code Labels');
$pdf->SetSubject('');
$pdf->SetKeywords('');

//remove header and footer
$pdf->setPrintHeader(false);
$pdf->setPrintFooter(false);

// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);

// set margins
$pdf->setTopMargin(13.0);
$pdf->SetRightMargin(6.0);

$pdf->setHeaderMargin(13);
$pdf->SetFooterMargin(13.0); //13mm

// set auto page breaks
$pdf->SetAutoPageBreak(TRUE, 13.0);

// set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);



// set a barcode on the page footer
//$pdf->setBarcode(date('Y-m-d H:i:s'));

// set font
$pdf->SetFont('helvetica', '', 11);

// add a page
$pdf->AddPage();

// print a message
//$txt = "";
//$pdf->MultiCell(70, 50, $txt, 0, 'J', false, 1, 125, 30, true, 0, false, true, 0, 'T', false);
//$pdf->SetY(30);

// -----------------------------------------------------------------------------

$pdf->SetFont('helvetica', '', 10);

请看上面回答的这个问题,我认为这只是一个宽度和高度计算问题。

以下解决方案对于几乎一维TCPDF标签打印可能有用。 该示例适合4列,并支持分页符,然后调整所需的参数。

df3 = pd.merge(
    left=df1,
    right=df2,
    left_on='uniquenumber',
    right_on='uniquenum2',
    how='both' # You can also use 'left' or 'right' here. If you use 'left', all values in the first dataframe are kept. Similar with 'right' but for the second dataframe.
)
