Question

我有一组按来源分类的表格，例如： “客户”，“股票”，“Floorstock”。它们看起来像这样：

每个都包含价格清单，需要在表格的最后一行加起来并总计。

我在将“totals”数组链接到“tables”数组时遇到问题 - 特别是在每个表的末尾显示每个总数

到目前为止，每个表的总数是在另一个函数中生成的，其中sourceTotals是一个实例数组：

public function setSourceTotalsArray($data)
{
    $this->sourceTotals = $data["source_totals"];
    return $this->sourceTotals;
}

这将返回一个如下所示的数组：

array(4) { ["Floorstock"]=> int(0) ["Stock"]=> int(0) ["Client"]=> float(32.18)  }

这是我定义$pdf对象的地方：

if($_SERVER["REQUEST_METHOD"] == "POST"){
$data = json_decode($_POST["printData"],true);
$pdf = new PDF();
// Column headings
$month = $pdf->getMonth($data['month']);
$year = $data['year'];
$pdf->SetFont('Arial','',10);
$pdf->AddPage();
$pdf>title(array('month'=>$month,'year'=>$year,'showroom'=>ucfirst($data['showroom_name'])));
$pdf->tableBody($data);

if(!empty($data["order_detail"])){
    $customerOrders = array();
    $stockOrders = array();
    $floorstockOrders = array();
    $otherOrders = array();

    foreach($data["order_detail"] as $o){
        switch($o["orderSource"]){
            case 'Client':
                $customerOrders[] = $o;
                break;
            case 'Stock':
                $stockOrders[] = $o;
                break;
            case 'Floorstock':
                $floorstockOrders[] = $o;
                break;

            default:
                $otherOrders[] = $o;
                break;
        }
    }

    if (!empty($customerOrders)) {
        $pdf->orderDetail($customerOrders, $data['currency'], 'Client');
    }

    if (!empty($stockOrders)) {
        $pdf->orderDetail($stockOrders, $data['currency'], 'Stock');
    }

    if (!empty($floorstockOrders)) {
        $pdf->orderDetail($floorstockOrders, $data['currency'], 'Floor Stock');
    }

    if (!empty($otherOrders)) {
        $pdf->orderDetail($otherOrders, $data['currency'], 'Client');
    }
}
$pdf->Output();

orderDetail函数是$pdf对象中表的结构，以便表中包含与正确列名对应的单元格：

function orderDetail($data,$currencyShortCode, $type){
    $this->orderType = $type;
    list($currencySymbol, $w_symbol, $cellHight) = $this->getOrderDetailHeader($currencyShortCode, $type);

    foreach ($data as $d){
        $commaValue = $this->addComma((float)$d['value']);
        $this->Cell(15,$cellHight,$d['order_no'],'LTB',0,'L');
        $this->Cell(20,$cellHight,substr($d['customer'],0,13),'TB',0,'L');
        $this->Cell(20,$cellHight,substr($d['company'],0,13),'TB',0,'L');
        $this->Cell(20,$cellHight,substr($d['ref'],0,13),'TB',0,'L');           
        $this->Cell(2,$cellHight,'','TB',0,'R');
        $this->Cell($w_symbol,$cellHight,$currencySymbol,'TB',0,'R');
        $this->Cell(16-$w_symbol,$cellHight,$commaValue,'TB',0,'R');
        $this->Cell(2,$cellHight,'','TB',0,'R');
        $this->Cell(10,$cellHight,$d['cat'],'TB',0,'L');
        $this->Cell(84,$cellHight,$d['description'],'RTB',0,'L');
        $this->Ln($cellHight);
    }
    //BOTTOM TOTAL
    $this->Cell(13,$cellHight,'TOTAL','LRTB',0,'L');
    $this->Cell(22,$cellHight,'','TB',0,'L');
    $this->Cell(20,$cellHight,'','TB',0,'L');
    $this->Cell(20,$cellHight,'','TB',0,'L');
    $this->Cell(4,$cellHight,$currencySymbol,'TB',0,'R');
    $this->Cell(14,$cellHight,$this->setSourceTotalsArray($data),'TB',0,'R'); //HERE
    $this->Cell(2,$cellHight,'','TB',0,'R');
    $this->Cell(10,$cellHight,'','TB',0,'L');
    $this->Cell(84,$cellHight,'','RTB',0,'L');
}

我只是不确定如何将setSourceTotalsArray传递给orderDetail，因为我当前的尝试只返回null。

Answer 1

您的setSourceTotalsArray方法实际上并没有做任何事情，因此如果它返回null，则表示$data没有source_totals节点。（建议/旁注：将error reporting设置为E_ALL，以便PHP向您发出警告;然后在实时环境中关闭display_errors并启用log_errors，这样您就会看到错误在日志中，但访问者不会在屏幕上看到它们。） source_totals中不存在$data的原因是完整脚本中的$ data variable inside orderDetail is only a subset of $ data`。

我要做的是向$total添加orderDetail参数。你得到这样的东西：

function orderDetail($data,$currencyShortCode, $type, $total) {
    ...
    $this->Cell(14,$cellHight, $total,'TB',0,'R'); //HERE
    ...
}

和

if (!empty($customerOrders)) {
    $pdf->orderDetail($customerOrders, $data['currency'], 'Client', $data['source_totals']['Client']);
}
// Also add the 4th argument for stock orders, floor orders and others.

另一种生成PDF的好方法就是使用wkhtmltopdf二进制文件。

如果您已经有一个生成html的报告，您可以使用输出缓冲生成html，然后转换为pdf，它可以在大多数环境中运行，您可以精确控制所需的输出，就像WebKit（Chrome， Safari等，使用熟悉的语言（HTML）来做。

HTH。
