Question

我有一个页面，我用它来检索一些用php写的excel数据...通过使用phpexcel ...这部分为我提供公司信息

echo '<form action="final.php" method="post">';
            echo "<table border='1'>";



            for ($rowcount = $rowCompanyInfoStart; $rowcount <= $rowCompanyInfoEnd; $rowcount++)
            { 

            //$data = $objWorksheet->rangeToArray('A1:' . $maxCell['column'] . $maxCell['row']);
            $rangeCoordinates = $colCompanyInfoStart . $rowcount . ':' . $colCompanyInfoEnd . $rowcount;
            $rowData = $sheet->rangeToArray($rangeCoordinates, NULL, TRUE, FALSE);
                    echo "<tr>";

              $companyname=$worksheet->getCell($column.$row)->getValue();
            //  echo $companyname;

                foreach($rowData[0] as $result) 
                                                {

            echo "<td>".$result." </td>";

                            }


                    echo "</tr>";
            }
                echo "</table>";

            echo "<br />";
        echo    '<input type="submit" name="sub" value="Convert into PDF" />';
    //  echo '<input type="text" name="resName" value="$result">';

        function getdatan() 
{ 
   global $result; // declare as global
   return $result;    
} 


    echo '</form>';

这部分是我获取公司信息的地方......它看起来像下方的表格区域......

enter image description here

我检索信息并能够显示为＆＃34; $ result＆＃34;变量和名为＆＃34的提交按钮;将其转换为pdf＆＃34;我把它发送到我使用TCPDF的其他php页面....

通常，第二页的这一部分

 $pdf->SetFont('times', 'BI', 12);

    // add a page
    $pdf->AddPage('L', 'A4');

    if(isset($_POST['submit']))
            {
    $result = $_GET['resName'];
    $pdf->Write(20, $result, '', 0, 'C', true, 0, false, false, 0);
          }

          // set some text to print
    $txt = <<<EOD
    TCPDF Example 003
    Custom page header and footer are defined by extending the TCPDF class and overriding the Header() and Footer() methods.
    EOD;

    // print a block of text using Write()

   // $pdf->Write(20, $resultt, '', 0, 'C', true, 0, false, false, 0);
    // ---------------------------------------------------------
     ob_end_clean();
    //Close and output PDF document
    $pdf->Output('example.pdf', 'I');

但是，我无法打印＆＃34; $ result＆＃34;在第二页......你能帮我讲解如何在pdf上打印这张表......

PS：请澄清你的帮助......

Answer 1

试试这个

更改： echo '<input type="submit" name="sub" value="Convert into PDF" />';

要：

echo    '<input type="submit" name="resName" value="Convert into PDF" />';

修改

将它放在第二页的开头：

var_dump($_POST);

只是检查您从第一页接收的内容。

同样改变：

$result = $_GET['resName'];

到此：

$result = $_POST['resName'];

Answer 2

好吧，因为我独自一人......我自己找到了解决方案.... 在PHP的第一页......

session_start();
//rest of your code and then...
    if($_SERVER['REQUEST_METHOD'] == 'POST') {
                echo '<form action="final.php" method="POST">';
                $tablo="<br />";
                $tablo = $tablo."<table border=\"1\" cellpadding=\"2\" cellspacing=\"2\" align='center'>";
                for ($rowcount = $rowCompanyInfoStart; $rowcount <= $rowCompanyInfoEnd; $rowcount++)
                { 
                    //$data = $objWorksheet->rangeToArray('A1:' . $maxCell['column'] . $maxCell['row']);
                    $rangeCoordinates = $colCompanyInfoStart . $rowcount . ':' . $colCompanyInfoEnd . $rowcount;
                    $rowData = $sheet->rangeToArray($rangeCoordinates, NULL, TRUE, FALSE);
                    //fazla bosluk olursa bunları aç ya da hucre bos mu kontrol et (cellExists ile) 
                    //rowData = array_map('array_filter', $rowData);
                    //$rowData = array_filter($rowData);    
                    $tablo= $tablo."<tr >";
                    $companyname=$worksheet->getCell($column.$row)->getValue();
                    //  echo $companyname;              
                    foreach($rowData[0] as $result) 
                    {
                        $tablo= $tablo. "<td>".$result. " </td>";
                    }
                    $tablo= $tablo. "</tr>";
                }
                $tablo= $tablo. "</table>";
                echo $tablo;
                echo "<br />";

                if($_SERVER['REQUEST_METHOD'] != 'POST') {
                    echo "SESSION Not AVAIL. first run.";
                }


                else{   
                    $_SESSION['varname'] = $tablo;
                    }

                echo    '<input type="submit" name="resName" value="Convert into PDF" />';

            }

所以我在这里使用了＆＃34; POST请求＆＃34;而不只是＆＃34; POST＆＃34;。它发送＆＃34; REQUEST＆＃34;没有任何＆＃34; POST DATA＆＃34; ...然后为了发送数据，我创建了一个名为＆＃34; $ table＆＃34;的变量。我将所有行和单元格信息放入其中并创建了一个会话，以便第二个PHP可以检索它....

在第二个PHP页面上，我回答＆＃34;请求＆＃34;并打开＆＃34;会话＆＃34;就像那样

session_start();

//rest of your code and then...

   if($_SERVER['REQUEST_METHOD'] != 'POST') {
            echo "SESSION Not AVAIL. first run.";
            $tablo = $_SESSION['varname'];
            echo "SESSION now set.";
        }
        else{   
            $tablo = $_SESSION['varname'];
            //echo "SESSION SET, value: " .$_SESSION['varname']. " and ". $_SESSION['color'];
        }
        if (isset($_SESSION['varname'])){
            $tablo = $_SESSION['varname'];
            // print_r($_SESSION);
            //echo "Session Set: <br/>" . $tablo;
        }
        else{
            echo "Session not set. Tablo is empty";
        //  echo "Session Set: <br/>" . $tablo;
        }

这样就可以了！
