我使用wkhtmltopdf包将我的html页面转换为.pdf文件。我想使用这个,所以顾客可以在3 x 7的标签纸上打印内容。标签的确切尺寸是70 x 42,3mm。问题是,我似乎无法正确调整尺寸。
我使用右侧浮点数和33%宽度来获得3列,现在我试图获得7行。我认为将它除以14.2%(7行)就可以了。但是它只会打印1个标签。当我删除高度时,它将打印所有标签,但每页超过7。有人帮我弄清楚如何获得标签的3x7 a4格式吗?
{% set labels = 1 %}
{% block body %}
{% for sale in webstore.getSales %}
{% for orderItem in sale.getOrderItems %}
{% if labels == 21 %}
<div style="page-break-after: before;" class="newPage"></div>
{% set labels = 1 %}
<br>
</div>
{%endif%}
<div class="stickerWidth" id="stickerWidth" >
<div class="text">
<div >{{sale.getWebstoreOrderId}} : <span style="float:right; margin-right:5px; font-size:20px" > {{sale.getDate.date | date("d/m/Y")}}</span> </div> <br><br>
<div style=" text-align:center;font-size: 24px;">{{orderItem.getAmount}} x {{orderItem.getItemName}}</div> <br>
<div>
{% if webstore.name %}
<span style="font-size:20px">
{{webstore.id}}<br>
{{webstore.name}}</span>
{% endif %}
</div>
</div>
</div>
{% set labels = labels + 1 %}
{% endfor %}
{% endfor %}
{% endblock %}
{% block styleSheets%}
<link rel="stylesheet" href="{{ base_dir ~ asset('css/main.css') }}">
<style>
.newPage {
page-break-after: always;
page-break-inside: avoid;
}
.stickerWidth{
height: 180px;
width: 33%;
float: left;
background-color: green;
}
.text{
background-color: red;
margin-right: 5px;
margin-top: 5px;
margin-top: 5px;
}
</style>
{% endblock %}
编辑:添加了最新的代码,如果我达到21,则使用标签计算新页面
答案 0 :(得分:1)
这里的快速解决方案: 要每21个标签创建一个新页面:
{% for orderItem in sale.getOrderItems %}
{% if (loop.index % (7*3) == 0) %}
<div class="newPage"></div>
{% endif %}
{# ... #}
的CSS:
.newPage {
page-break-before:always
}
我自己的实施: 控制器:
public function export() {
$html = $this->get('yourPDFservice')->getHtml($someParams);
//echo $html;exit; // use that to debug your html
$snappyPdf = $this->getLibExportPDF();
return new Response(
$snappyPdf->getOutputFromHtml($html),
200,
array(
'Content-Type' => 'application/pdf',
'Content-Disposition' => 'attachment; filename="filename.pdf"'
)
);
private function getLibExportPDF() {
$snappyPdf = $this->get('knp_snappy.pdf');
$snappyPdf->setOption('page-size', 'A4');// 21x29.7 cm
$snappyPdf->setOption('zoom', 1 );
$snappyPdf->setOption('dpi', 300 );// 21x29.7 (300dpi)
return $snappyPdf;
}
html:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<style>
.nobreak {
page-break-inside:avoid;
}
.newPage {
page-break-before:always;
}
</style>
</head>
<body>
{# Your html code here #}
</body>
</html>
