Question

我正在尝试上传图片并使用数据库显示它我设法上传并连接到数据库，但它没有显示它有人可以看看我的代码，告诉我我做错了什么：

db.php：

    <?php   
 $host = "localhost";
 $username = "root";
 $password = "";
 $db_name  = "db_php_school";

  mysql_connect($host,$username,$password) or die("Database not connect");
 mysql_select_db($db_name) or die ("could not connect databse");
 error_reporting("E_ERROR_WORKING");
 echo "Database connecet success";


?>

这是index.php：

<?php 


include './classes/image_class.php';

$obj_image = new Image();

if(@$_POST['Submit'])
{
 $obj_image->image_name=str_replace("'", "''", $_POST['txt_image_name']);
 $obj_image->image=str_replace("'", "''", $_POST['txt_image']);

  $obj_image->Insert_into_image();

  $data_image=$obj_image->get_all_image_list();
 $row=mysql_num_rows($data_image);
}

?>

  <form method="post" enctype="multipart/form-data">

    <tr>
     <th width="50%">Image NAme</th>
     <td width="50%"><input type="text" name="txt_image_name"></input></td>

     <td width="50%"><input type="submit" name="Submit" value="Submit"></input></td>
    </tr>
   </table>
  </form>

  <?php 
  if($row!=0)
  {
  ?>
  <center>
   <table width="80%" border="1"> 
   <?php
    $icount = 1;
    while($data= mysql_fetch_assoc($data_image))
    {
     ?>
     <tr>
      <td style="text-align:center" style="width:10%;"><?php echo $icount; ?></td>
      <td style="text-align:center" style="width:20%;"><?php echo $data['image_name']?></td>
      <td style="text-align:center" style="width:50%;><img src="images/<?php echo $data['image']; ?>" width="400px" height="200px"></td>
     </tr>
     <?php
     $icount++;
     }
     ?>
   </table>
  </center>
  <?php
 }

  ?>
</body>
</html>

这是image_class.php

<?php
 include 'db/db.php' ;

  class Image{

   var 
   $image_id,
   $image_name,
   $image;

  function Insert_into_image(){
   if(isset($_FILES['txt_image']))
   {
        $tempname = $_FILES['txt_image']['tmp_name'];
        $originalname =$_FILES['txt_image']['name'];
        $size =($_FILES['txt_image']['size']/5242888). "MB<br>";
        $type=$_FILES['txt_image']['type'];
        $image=$_FILES['txt_image']['name'];
        move_uploaded_file($_FILES['txt_image']['tmp_name'],"images/".$_FILES['txt_image']['name']);
      }


    $query = "Insert into t_image_upload
    (
     image_name,
     image
    )
    values
    (
     '$this->image_name',
     '$image'
    )";
    if(mysql_query($query)){
     echo "Insert success";
    }
    else
    {
     echo "Insert not success";
    }
  }

   function get_all_image_list(){
   $query = "select *from t_image_upload";
   $result = mysql_query($query);
   return $result;
  }

}
?>

但问题可能在第63行的index.php中列出

 <td style="text-align:center" style="width:50%;><img src="images/<?php echo $data['image']; ?>" width="400px" height="200px"></td>
     </tr>

这里有一些屏幕截图：

Answer 1

首先，检查图像上传到文件夹，然后尝试给出像

这样的绝对路径

<tr>
<td style="text-align:center" style="width:50%;>
<img src="http://localhost/project/images/<?php echo $data['image']; ?>" width="400px" height="200px">
</td>
</tr>

php上传图片并显示数据库（错误）
