PHP+TCPD foreach 故障

Question

我是 PHP 新手。我的目标是使用 TCPDF 库将用户在表单字段中插入的数据传输到 PDF。在 Windows XP 上它工作正常，一切正常，但如果我尝试在 Windows 7 上生成 PDF，它会给我以下报告。

Notice: Undefined index: startcolumn in C:\xampp\htdocs\tcpdf\tcpdf.php on line 19345
Notice: Undefined index: startx in C:\xampp\htdocs\tcpdf\tcpdf.php on line 19346

TCPDF ERROR: Some data has already been output, can't send PDF file

这是有问题的代码：

foreach( $_POST['mat_tit'] as $key => $_POST['mat_tit'] ) {
    $mat_list_data = '
    <table cellpadding="1" cellspacing="0">
        <tr>
            <td width="100%">'.$_POST['mat_tit'].'</td>
        </tr>
    </table>
    <table cellpadding="2" cellspacing="2">
        <tr>
            <td width="13%">'.$mat_up[$key].'</td>
            <td width="5%">Kč</td>
            <td width="12%">'.$mat_q[$key].'</td>
            <td width="5%">'.$mat_ut[$key].'</td>
            <td width="5%">'.$mat_c[$key].'</td>
            <td width="13%">'.$mat_isum[$key].'</td>
            <td width="5%">Kč</td>
            <td width="6%">'.$mat_vv[$key].'</td>
            <td width="13%">'.$mat_vs[$key].'</td>
            <td width="5%">Kč</td>
            <td width="13%">'.$mat_itot[$key].'</td>
            <th width="5%">Kč</th>
        </tr>
    </table>';
}

// print $mat_list_data
$pdf->writeHTML($mat_list_data, true, true, false, false, '');

有没有人可以帮我解决这个问题？非常感谢大家

您需要删除代码中的双引号并在表格中使用单引号；

$mat_list_data = "
<table cellpadding='1' cellspacing='0'>
....
....        
....
";
