我想要做的是,准备PHP生成的结果用于强大规则的打印。
尝试使用css + html的所有可能方法:以px,mm,cm设置尺寸。 什么都没有帮助。每个浏览器,甚至每台打印机都打印出完全不同的纸张结果(尝试使用& w / o border print。也没有得到结果)。经过长时间的研究,发现CSS不是用于此目的的最佳方式和更好的方式 - 使用PHP的pdf创建功能。所以,安装了TCPDF。但是无法使用我为HTML输出创建的逻辑部分。
$id
)以下是有关图片的更详细说明:
表单提交后,php端的处理时间过长 - 大约分钟并打开空白页而不是PDF结果。
(代码不是很大,评论看起来像这样:)

这是一个html / css到pdf转换器库http://www.mpdf1.com/mpdf/
这有它自己的html / css解析器,因此会在所有浏览器中产生相同的结果。
<?php
$html = '

我认为,如果你根本没有得到结果,你可能会以某种方式压制错误,你不能用脚本获取错误。此外,您使用HTML的方法不是它的工作原理;您不能使用HTML交错TCPDF本机单元调用;他们不是“输出”标记。因此,您将混合两种不同的,不兼容的格式,这两种格式将转移到两个不同的缓冲区。
但是,您的代码仍应生成PDF。
请注意最后一页,其中包含标记生成的内容。
我所做的唯一更改是将其设置为无法访问您的数据而无法运行的地方:
$i = 0;
//$item = new item($db);
//foreach ($_POST['checkbox'] as $id) {
for ($id = 0; $id < 1; $id++) {
//$details = $item->getDetails($id);
//$qt = (isset($_POST['qt'])) ? $_POST['qt'] : $details['qt'];
$details = array('These are details');
$qt = 50;
for ($cnt = 1; $cnt <= $qt; $cnt++) {
// check if it's the beginning of a new table
if ($i % 65 == 0)
echo '<table>';
// check if it's the beginning of a new row
if ($i % 5 == 0)
echo '<tr>';
echo '<td><div class="cell">www.fety.fr<br/>';
$pdf->Cell(0, 0, 'CODE 39 - ANSI MH10.8M-1983 - USD-3 - 3 of 9', 0, 1);
$pdf->write1DBarcode($id, 'C39', '', '', '', 18, 0.4, $style, 'N');
$pdf->Ln();
echo '<br/>' . $details['hcode'] . '</div></td>';
// check if it's the end of a row
if (($i + 1) % 5 == 0)
echo '</tr>';
// check if it's the end of a table
if (($i + 1) % 65 == 0)
echo '</tr></table>';
$i++;
}
}
我收到了PDF。它看起来与图像中的内容完全不同,但它确实产生了PDF。我看到你的代码与TDPDF网站上的这个例子大约有90%相似:
http://www.tcpdf.org/examples/example_027.phps
当我进入并做出我自己的榜样时,我能够获得一个通常模仿你在照片中显示的内容的PDF。正如您在下面的代码中所看到的,您有使用本机TCPDF单元格方法来使条形码生成起作用。这并不难;我花了大约30分钟来弄清楚如何制作PDF格式。
我唯一想不到的是顶部的黑线来自哪里;它以某种方式与标题相关联,但我无法找到将其关闭的位置。第二个PDF背后的代码:
<?php
require_once('tcpdf/config/lang/eng.php');
require_once('tcpdf/tcpdf.php');
// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
//set auto page breaks
$pdf->SetAutoPageBreak(TRUE);
//set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
//set some language-dependent strings
$pdf->setLanguageArray($l);
$pdf->SetFont('helvetica', '', 10);
// define barcode style
$style = array(
'position' => '',

);
for ($o = 0; $o < 5; $o++) {
$pdf->AddPage();
$y = 10;
for ($i = 0; $i < 13; $i++) {
$x = 10;
for ($p = 0; $p < 5; $p++) {
// UPC-E
$pdf->write1DBarcode('04210000526', 'UPCE', $x, $y, 37, 20, 0.4, $style);
$x = $x + 38;
}
$y = $y + 21;
