PDF上的图像无法正常显示

我再次遇到PHP问题。

我正在制作PDF,我必须在网页上显示也会出现的图片。

问题是图像没有在PDF上显示。

实际上它是一种不同的图像,实际上更像是图表。

您在网页中执行的所有操作都显示在图表中,我必须将其打印在PDF中,但PDF只是忽略了打印命令。

HTML代码示例(工作得很好):

<html>
<h3>
you can take files copies in xls or Pdf format
</h3>
<br> <a href="../useful/excel.php"> Generate excel file</a> <br> <BR>
<form method="post" action=""  target="_blank">
<input type="submit" name="pdf"  value="generate PDF " />
<input type="hidden" id="hide" name="hide">
</form><br>
<center><div id="image" name="image"><img src="../useful/createchart.php"/></div>            </center>
</html>

正如您所看到的,它使用PHP文件来创建图表(这不是一个类,它只是一个带有一些方法的PHP文件)。

所以我对于我要对PDF中显示的图像做了什么无能为力。

顺便说一下,我正在使用mPDF。

在这里,我有一部分代码来打印PDF,这就是重要的部分。它可以很好地打印表格,但它根本不打印图像。

<?php // create PDF report ...

if (isset($_POST['pdf'])){
 $mpdf = new mPDF();
//foreach ($showmore as $items){
$array = explode('-', $store); 
//$Result = array();
foreach ($array as $member){
    if($member != '')
 $res= $dao->getinfobynumber ('jc', $member); 
//var_dump($res);

 foreach ($res as $jcvalue){

 $mpdf->SetHeader("Tabela");
 $mpdf->SetFooter(date('l jS \of F Y h:i:s A'));
     $htmlpdf2 .= "     
    <table  border='1'>

        <tr>
            <th width='150'>GE</th>
            <td width='200'>". $jcvalue->getsg()."</td>
            <td width='200'><strong>Nome Curto</strong></td>
            <td width='200'>". $jcvalue->getnomecurto()."</td>
        </tr>
    </table>

    <table border='1'>
        <tr>
            <th width='150'>Valor</th>
            <td width='200'>". $jcvalue->getpvalor() ."</td>
            <td width='200'><strong>FC</strong></td>
            <td width='200'>". $jcvalue->getfc() ."</td>
        </tr>
    </table>

        <table border='1'>
        <tr>
            <th width='150'> Jugular </th>
            <td width='117'>". $jcvalue->getjugular1() ."</td>
            <td width='117'>". $jcvalue->getjugular2() ."</td>
            <td width='117'>". $jcvalue->getjugular3() ."</td>
            <td width='118'>". $jcvalue->getjugular4() ."</td>
            <td width='119'>". $jcvalue->getjugular5() ."</td>

        </tr>
    </table>

    <table border='1'>
        <tr>
            <th width='150'>EXP3D</th>

            <td width='200'>". $jcvalue->getd3_2() ."</td>
            <td width='200'>". $jcvalue->getd3_3() ."</td>
        </tr>
        </table>

        <table border='1'>

        <tr>
            <th width='150'>EXP28D</th>
            <td width='200'>". $jcvalue->getd28_1() ."</td>
            <td width='200'>". $jcvalue->getd28_2() ."</td>
            <td width='200'>". $jcvalue->getd28_3() ."</td>
        </tr>
    </table>

    <table border='1'>

        <tr>
            <th width='150'>Carotida</th>
            <td width='303'>". $jcvalue->getcarotida_1() ."</td>
            <td width='303'>". $jcvalue->getcarotida_2() ."</td>
        </tr>


    </table>

        <br><br>";
   }


    }

    $PDFimage = "<center><div id='image' name='image'><img   src='../useful/createchart.php'/></div></center>";
   $mpdf->WriteHTML($htmlpdf2);
    $mpdf->WriteHTML($PDFimage);

    $mpdf->Output();

   }

这里是使用网页选择你想要看到的内容的代码,apge会根据你选择的内容和基于数据的图表来提供所有数据:

  <?php session_start();

  // will include in this file simple table contains all informations 
  // also will calling function from creat table and also will call function create       chart and export to excel
