在PHP中使用PDF

时间:2012-02-12 11:46:10

标签: php pdf printing tcpdf

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。

我想得到什么

  • 表格的顶部和底部两侧的第一行和最后一行的边距必须 11 mm
  • 行之间的边距'0 mm
  • 表格的行必须位于 4 mm <纸张的左右
  • 每列之间
  • 2 mm
  • 38 mm宽x 21.2 mm高每个细胞
  • 13行,5 x列,13x5 = 65个单元
  • 新页面中的每个表格。换句话说 - 在每个表分页
  • 之后
  • 在每个单元格中Code 39条形码(值必须为$id
  • 只有PDF格式的表格 - 没有标题,没有页脚,没有标题......等等。

以下是有关图片的更详细说明:

我得到了什么

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:

(代码不是很大,评论看起来像这样:)

脚本的工作原理如下:

  1. 用户选择项目复选框
  2. 表单提交后,PHP通过Ajax获取已选中复选框的值
  3. 在foreach循环中,PHP从数据库中获取每个项目的数量。
  4. 生成表

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 = '
    <html>
    <head>
    <style>
        table {
        width: 100%;
            border-collapse: collapse;
        }       
        tr {

        }
        td {
            width: 38mm;
            height: 21.2mm;
            margin: 0 1mm;
            text-align: center;
            vertical-align:middle; 
        }
    </style>
    </head>
    <body>
    <table>';

    for ($i = 0; $i < 13; $i++)
    {
        $html .= '<tr>';
        for($j = 0; $j < 5; $j++)
        {
            $html .= '<td><barcode code="TEC-IT" type="C39" class="barcode" /></td>';
        }
        $html .= '</tr>';
    }       

$html .= '</table>
    </body>
    </html>';

    include("MPDF53/mpdf.php");

    $mpdf = new mPDF('c', 'A4', '', '', 4, 4, 10.7, 10.7, 0, 0);

    $mpdf->SetDisplayMode('fullpage');

    $mpdf->list_indent_first_level = 0;

    $mpdf->WriteHTML($html,0);

    $mpdf->Output('test.pdf','I');
    exit;

?>

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' => '',
    'align' => 'L',
    'stretch' => true,
    'fitwidth' => false,
    'cellfitalign' => '',
    'border' => true,
    'hpadding' => 'auto',
    'vpadding' => 'auto',
    'fgcolor' => array(0,0,0),
    'bgcolor' => false, //array(255,255,255),
    'text' => true,
    'font' => 'helvetica',
    'fontsize' => 8,
    'stretchtext' => 4
);

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;

        $pdf->Ln();
    }
}

//Close and output PDF document
$pdf->Output('example_027.pdf', 'I');

以下链接指向与您的图片完全相同的pdf:

Link to embrasse-moi.com barcode label file

这是创建它的函数。我用tcpdf。我创建了3行文本,id,描述,价格,我从子id中查找,以便您必须替换代码。我还传入行/列偏移量以便与avery5167一起使用,因此我们可以使用所有贴纸。

    function printProductLabelsAvery5167($product_sub_ids, $quantities, $row_offset, $column_offset, $filename)
