Question

修改代码

<?php
            require_once("dompdf/dompdf_config.inc.php");

               $date=date("m/d/Y");
               echo "Today Date Is = ";
               echo "$date";
               echo "<h1><center>order status </center></h3>";

            include("../../../../../../../inetpub/wwwroot/dbcon/connection.php");

             $content="";

            if(isset($_POST['submit']))
            {
              include("../../../../../../../inetpub/wwwroot/dbcon/connection.php");
              $content .=  "<h3>Customer order</h3>";
              $search=htmlspecialchars($_POST['search']);
              $selectcondition = "SELECT * FROM customer.order where DATE='".$search."'"; 
              $check=mysql_query($selectcondition,$con);
              $fetch=mysql_fetch_row($check); 

               if(!$fetch)                          
               {

                  $content .=   "<font color='red'>";
                  $content .=    "<br>";
              $content .=  "No order Found In The Database"; 
              $content .=  "<br>";
                  $content .=   "</font>";
              return $content;

            }

             else //if the above condition is flase !
                 {

               $sql= "select * from customer.order  where DATE='".$_POST['search']."'";
                   $mydata=mysql_query($sql,$con);

 $content .=  "<table class='mytable' width='100%' height='10%' border='1' cellspacing='0'>

                             <tr>
                              <th>DATE</th>
                              <th>ORDER</th>
                              <th>CUSTNAME</th>
                              <th>COMMENTS</th>

                             </tr>";

                while($records = mysql_fetch_array($mydata))

                {

                            $content .= "<tr>";
                            $content .="<td>" . $records['TIMESTAMPS'] . "&nbsp;</td>";
                            $content .= "<td>" . $records['ORDER']. "&nbsp;</td>";
                            $content .= "<td>" . $records['CUSTNAME'] . "&nbsp;</td>";
                            $content .="<td align='center'>";
                            $content .= '<textarea  name="textarea" cols="100"  >'.$records['COMMENTS'].'</textarea><br>'; 

                            $content .=  "</td>";

                }

                     "</table>";

            }
        }

          $html= $content;
          $dompdf = new DOMPDF();
          $dompdf->load_html($html);
          $dompdf->render();
          $dompdf->stream("order.php");

          ?>

我已根据最近的更改修改了我的代码，我删除了内容功能并将所有内容都包含在 $ content 变量中。

之后生成损坏的PDF。请帮我解决这个问题。

再次感谢您的回复。

Answer 1

你错了

$dompdf->load_html($html);

根据docs

$html =
  '<html><body>'.
  '<p>Put your html here, or generate it with your favourite '.
  'templating system.</p>'.
  '</body></html>';

并且您始终使用echo来输出内容。尝试首先创建对象，然后return，所以它确实存在于变量:)中，没有回声，它们应该可以工作。

所以你的代码看起来像这个fx ::

if(isset($_POST['submit'])){
    include("../../../../../../../inetpub/wwwroot/dbcon/connection.php");

     $content = "<h3>Turnover For Apria</h3>";

     $search=htmlspecialchars($_POST['search']);
     $selectcondition = "SELECT * FROM customer.order where DATE='".$search."'"; //Select Query Which check the whether the TURNOVER for the given INCIDENT is exit or not.

     $check=mysql_query($selectcondition,$con);
     $fetch=mysql_fetch_row($check); 

    if(!$fetch)                         //If checklist for the given date is not exit execute if condition 
    {

        $content .= "<font color='red'>";
        $content .= "<br>";
        $content .= "No records Found In The Database"; 
        $content .= "<br>";
        $content .= "</font>";
        return $content;

    }

所以创建一个变量，将html附加到它并在每次需要时将其返回。应该工作

我想这会做，测试并让我知道::::

<?php
require_once("dompdf/dompdf_config.inc.php");

   $date=date("m/d/Y");
   echo "Today Date Is = ";
   echo "$date";
   echo "<h1><center>Midrange, Turnover For All The Accounts </center></h3>";


    //include("../../../../../../../inetpub/wwwroot/dbcon/connection.php");
    //WHY DO YOU NEED THIS TO BE TWICE?

function content()
{   

    //init the content variable
    $content = null;

    if(isset($_POST['submit']))
    {
         include("../../../../../../../inetpub/wwwroot/dbcon/connection.php");

         $content .= "<h3>Turnover For Apria</h3>";

         $search=htmlspecialchars($_POST['search']);
         $selectcondition = "SELECT * FROM customer.order where DATE='".$search."'"; //Select Query Which check the whether the TURNOVER for the given INCIDENT is exit or not.

         $check=mysql_query($selectcondition,$con);
         $fetch=mysql_fetch_row($check); 

    if(!$fetch)                         //If checklist for the given date is not exit execute if condition 
    {

        $content .= "<font color='red'>";
        $content .= "<br>";
        $content .= "No records Found In The Database"; 
        $content .= "<br>";
        $content .= "</font>";

        return $content;

    }

     else //if the above condition is flase !

     {

        $sql= "select * from customer.order where DATE='".$_POST['search']."'";


        $mydata=mysql_query($sql,$con);
        //$fetch_rows=mysql_fetch_row($mydata);

         $content .= "<table class='mytable' width='100%' height='10%' border='1' cellspacing='0'>

                     <tr>
                      <th>DATE</th>
                      <th>ORDER</th>
                      <th>SUTNAME</th>
                      <th> COMMENTS</th>

                     </tr>";

        while($records = mysql_fetch_array($mydata))

        {

            $content .= "<tr>";
                    $content .= "<td>" . $records['TIMESTAMPS'] . "&nbsp;</td>";
                    $content .= "<td>" . $records['ORDER']. "&nbsp;</td>";
                    $content .= "<td>" . $records['CUSTNAME'] . "&nbsp;</td>";
                    $content .= "<td align='center'>";
                    $content .= '<textarea  name="textarea" cols="100"  >'.$records['COMMENTS'].'</textarea><br>'; 
            $content .= "</td>";

        }

    }

          $content .= "</table>";

          return $content;
    }


  $html=content();
  if($html){
      $dompdf = new DOMPDF();
      $dompdf->load_html($html);
      $dompdf->render();
      $dompdf->stream("order.pdf");
  }else{
    echo "Look like something is wrong here .";
  }


?>

第二次更新

此示例正常运行，请确保您已包含所有正确的文件并修复所有语法错误，例如一个额外的}也请更改为mysqli_*

<?php
$html=content();
if($html){
  require_once("dompdf_config.inc.php");
  $dompdf = new DOMPDF();
  $dompdf->load_html($html);
  $dompdf->render();
  $dompdf->stream("order.pdf");
}else{

  echo "Look like something is wrong here .";
}
function content(){
    $content = null;
    $content .= "<table class='mytable' width='100%' height='10%' border='1' cellspacing='0'>

                     <tr>
                      <th>DATE</th>
                      <th>ORDER</th>
                      <th>SUTNAME</th>
                      <th> COMMENTS</th>

                     </tr>";

  $content .= "</table>";

  return $content;
}
$date=date("m/d/Y");
echo "Today Date Is = ";
echo "$date";
echo "<h1><center>Midrange, Turnover For All The Accounts </center></h3>";
?>

它必须按此顺序处理，因为它必须尊重php中的标题，此示例将生成可以打开的正确pdf，只需要填充正确的数据

无法使用DOMPDF导出pdf
