Question

我在PHP中使用 HTML to PDF方法来处理PDF格式。我成功地从数据库中检索了数据。我在行之间得到更多空格为什么？请建议我。这是我的代码......

require('WriteHTML.php');
include('connection.php');
$result = pg_query($db,"SELECT dvn_cd, allotment_date,allotment_no,quantity FROM ddhs_receipt_entry ");

$pdf=new PDF_HTML();

$pdf->AliasNbPages();
$pdf->SetAutoPageBreak(true, 15);

$pdf->AddPage();
$pdf->Image('logo.png',18,13,33);
$pdf->SetFont('Arial','B',14);
$pdf->WriteHTML('<para><h1>Title</h1><br>');

$pdf->SetFont('Arial','B',7); 
$htmlTable='<TABLE>
<TR>
<TD>Name</TD>
<TD>Email</TD>
<TD>URl</TD>
<TD>Comment</TD>
</TR>
</TABLE>';

$pdf->WriteHTML2("$htmlTable");
while($value = pg_fetch_array($result)) {

$htmlTable2='<TABLE>
<TR>
<TD>'.$value['dvn_cd'].'</TD>
<TD>'.$value['allotment_date'].'</TD>
<TD>'.$value['allotment_no'].'</TD>
<TD>'.$value['quantity'].'</TD>
</TR>
</TABLE>';
$pdf->WriteHTML2("$htmlTable2");
$pdf->SetFont('Arial','B',6);

 }

 $pdf->Output();

Answer 1

您正在做的事实上是输出大量单独的表，而您只需要一个表。尝试在<TABLE>循环之外移动while：

$htmlTable = '<TABLE>
    <TR>
    <TD>Name</TD>
    <TD>Email</TD>
    <TD>URl</TD>
    <TD>Comment</TD>
    </TR>';    // The table is opened at the start of this block, and headers are output

while($value = pg_fetch_array($result)) {

    $htmlTable .= '<TR>
        <TD>'.$value['dvn_cd'].'</TD>
        <TD>'.$value['allotment_date'].'</TD>
        <TD>'.$value['allotment_no'].'</TD>
        <TD>'.$value['quantity'].'</TD>
        </TR>';    // Each row of your table is added to the string here

}

$htmlTable .= '</TABLE>';    // The table is closed here

$pdf->WriteHTML2("$htmlTable");    // The table is written here

$pdf->Output();

Answer 2

试试这个：

while($value = pg_fetch_array($result)) {

$htmlTable2='<TR>
    <TD>'.$value['dvn_cd'].'</TD>
    <TD>'.$value['allotment_date'].'</TD>
    <TD>'.$value['allotment_no'].'</TD>
    <TD>'.$value['quantity'].'</TD>
    </TR>';
$pdf->WriteHTML2("$htmlTable2");
$pdf->SetFont('Arial','B',6);

 }
$htmlTable='</TABLE>';

PDF创建是可以的，但从数据库中获取行空间
