Question

我试图在我的pdf中添加一个自动递增的序列号列。我试图从数据库中获取它，但由于检索的数据是随机的，因此pdf上打印的序列号也是随机的。我想开始像1,2,3 ......

$sql2 = "SELECT * FROM `" . $DB->pre . "order_detail` 
        WHERE orderID= '$orderID'"; 
$rows2 = $DB->dbRows($sql2);

if ($DB->numRows > 0){

    $pdf->SetLineWidth(0);
    $pdf->SetFont('Arial','',10);
    $newL=110;         ////fixed cell spaced in y-axis for quantity
    $cnt=0;
    foreach ($rows2 as $d2) {
        $rows2++;
        $pdf->SetXY(11,$newL);
        $pdf->Cell(11,7, ,1,0,'L',0); /////SERIAL NUMBER COLUMN/////
        $pdf->SetXY(22,$newL);
        $pdf->Cell(22,7,$d2['materialDesc'],1,0,'L',0);
        $pdf->SetXY(44,$newL);
        $pdf->Cell(15,7,$d2['chart'],1,0,'L',0);
        $pdf->SetXY(59,$newL);
        $pdf->Cell(25,7,$d2['shade'],1,0,'L',0);
        $pdf->SetXY(84,$newL);
        $pdf->Cell(18,7,$d2['materialSize'],1,0,'L',0);
        $pdf->SetXY(102,$newL);
        $pdf->Cell(25,7,$d2['quantity'],1,0,'L',0);
        $pdf->SetXY(127,$newL);
        $pdf->Cell(15,7,'ROL',1,0,'L',0);
        $pdf->SetXY(142,$newL);
        $pdf->Cell(18,7,'OPEN',1,0,'L',0);
        $pdf->SetXY(160,$newL);
        $pdf->Cell(35,7,$d2['remarks'],1,0,'L',0);
        $newL += 7;  
    }     
}
$pdf-> Ln();

然后你只需要一个柜台。

$sql2 = "SELECT * FROM `" . $DB->pre . "order_detail` 
        WHERE orderID= '$orderID'"; 
$rows2 = $DB->dbRows($sql2);

if ($DB->numRows > 0){

    $pdf->SetLineWidth(0);
    $pdf->SetFont('Arial','',10);
    $newL=110;         ////fixed cell spaced in y-axis for quantity

    // you already had a counter so I am reusing it
    $cnt=1;

    foreach ($rows2 as $d2) {
        $rows2++;
        $pdf->SetXY(11,$newL);

        // place counter in column
        $pdf->Cell(11,7, $cnt,1,0,'L',0); /////SERIAL NUMBER COLUMN/////
        $pdf->SetXY(22,$newL);
        $pdf->Cell(22,7,$d2['materialDesc'],1,0,'L',0);
        $pdf->SetXY(44,$newL);
        $pdf->Cell(15,7,$d2['chart'],1,0,'L',0);
        $pdf->SetXY(59,$newL);
        $pdf->Cell(25,7,$d2['shade'],1,0,'L',0);
        $pdf->SetXY(84,$newL);
        $pdf->Cell(18,7,$d2['materialSize'],1,0,'L',0);
        $pdf->SetXY(102,$newL);
        $pdf->Cell(25,7,$d2['quantity'],1,0,'L',0);
        $pdf->SetXY(127,$newL);
        $pdf->Cell(15,7,'ROL',1,0,'L',0);
        $pdf->SetXY(142,$newL);
        $pdf->Cell(18,7,'OPEN',1,0,'L',0);
        $pdf->SetXY(160,$newL);
        $pdf->Cell(35,7,$d2['remarks'],1,0,'L',0);
        $newL += 7;  
        // add 1 to the counter
        $cnt++;
    }     
}
$pdf-> Ln();
