 <?php

 include 'connection.php';

 if(isset($_POST['val'])){
 $a = $_POST['val'];

 $sql = "SELECT * FROM car_details where id= '".$a."'";
    $retval = mysql_query( $sql, $con );
  if(! $retval ) {
   die('Could not get data: ' . mysql_error());
  }

 while($row = mysql_fetch_array($retval, MYSQL_ASSOC)) {

     $ID = $row['ID'];
     $Name = $row['Car_Name'];
     $Category = $row['Category'];
     $Transmision = $row['Transmision'];
     $Seats = $row['seats'];
     $EnginePower = $row['EnginePower'];
     $EngineCapacity = $row['EngineCapacity'];
     $MaxSpeed = $row['MaxSpeed'];
     $TankCapacity = $row['TankCapacity'];
     $Car_Details = $row['Car_Details'];
     $img = $row['image_path'];

 }

    }
  ?>

它的php脚本从db获取数据，但它没有设置为html标记

<body>

    <table id="car-tbl">
<div id="name"><center><h3><?php echo $Name; ?></h3></center></div><br />
<tr><td>Category</td><td>&nbsp;</td><td>Sport Car</td></tr>
<tr><td>Transmission</td><td>&nbsp;</td> <td>Automatic</td></tr>
<tr><td>Seats</td> <td>&nbsp;</td><td>2</td></tr>
<tr><td>Engine Power</td><td>&nbsp;</td> <td>420 hp</td></tr>
<tr><td>Engine Capacity</td> <td>&nbsp;</td><td>4200cc</td></tr>
<tr><td>Max Speed</td> <td>&nbsp;</td><td>301 km/h</td></tr>
<tr><td>Tank Capacity</td><td>&nbsp;</td><td>75 lt</td></tr>
<tr><td>GPS</td><td>&nbsp;</td><td>Yes</td></tr>
</table>

</body>

php脚本在html体外，我想在html表中添加这些PHP数据变量，因为你可以看到我已经在标签中实现了一些php代码，但它不起作用，但是它生成了它是未定义的变量

帮帮我

请尝试以下代码

  include 'connection.php';

  if(isset($_POST['val'])){
   $a = $_POST['val'];

    $sql = "SELECT * FROM car_details where id= '".$a."'";
    $retval = mysql_query( $sql, $con );
    if(! $retval ) {
      die('Could not get data: ' . mysql_error());
    }

    while($row = mysql_fetch_array($retval, MYSQL_ASSOC)) {

     echo "<html><body><table id='car-tbl'><div id='name'><center><h3>";
     echo $Name = $row['Car_Name'];
     echo "</h3></center></div><br />";
     echo "<tr><td>Category</td><td>&nbsp;</td>";
     echo $Category = $row['Category'];
     echo "</tr>";
     echo "</table></body></html>";

    }

 }
