显示来自数据库的图像时出现问题

时间：2018-09-25 06:30:51

标签： php html

我需要有关我的源代码的帮助，以在我的用户的个人资料上载和显示他们的个人资料图片。 上载顺利，但显示不顺利。用户图片的显示仅显示在图片图标中，而不显示在真实图片中。像这样：

enter image description here

存储图片的文件在这里 enter image description here

这是我的源代码

edit-profile.php 

<div class="author">
<a href="#">
<img class="avatar border-gray" src="../uploads/candidate/<?php echo $row['photo']; ?>" alt="..."/>
 <h4 class="title"><?php echo $_SESSION['name']; ?><br /> </h4>
 </a>
</div>

编辑：

我将在此处提供userindex.php和edit-profile.php的完整源代码，以便你们中的任何人都可以指出我做错的地方。

您的$_SESSION数组userindex.php文件中有问题。您已经错过了会话​​密钥' 

$sql = "SELECT * FROM users WHERE id_user='$_SESSION[id_user]'";

因此，首先将其分配给变量，然后将该变量放入sql查询中

$id_user = $_SESSION['id_user'];// single quotes for session key
$sql = "SELECT * FROM users WHERE id_user='$id_user'";

注意：  您的代码对sql注入开放。尝试use PDO或准备好的语句

检查您的update-profile.php

那里发生了混乱，因为您为图像和简历的文件类型都输入了相同的“文件名”。您应该改为这样

  header("Location: ../index.php");
  exit();

//Including Database Connection From db.php file to avoid rewriting in all files

我已经尝试过您以前的代码，导致该图像以pdf格式存储，这就是为什么当您要求显示该图像时，它却显示为残破的图像图标。希望这对您有帮助，祝您好运！

答案 2 :(得分：0)

尝试此代码

<img src="uploads/candidate/.'<?php echo row['photo']; ?>'"/>

答案 3 :(得分：0)

您需要确保$row值确实有价值。 试试看，看看是否有任何结果：

 die(var_dump("../uploads/candidate/".$row['photo'] ));

您将获得代码所引用的路径，如果没有给出结果，请再次检查您的查询（检查行是否有值）

答案 4 :(得分：0)

您可以执行此操作，引入一个外部php文件，例如get.php，然后从此get.php请求照片。 请参见下面两个文件的示例。

display.php文件

<?php
$id = row['id'];

<img class="avatar" src=get.php?id=$id alt="profile photo" />
 ?>

get.php文件

<?php
 // make connections with database here
$id = $_REQUEST['id'];

$image = ("SELECT * FROM table WHERE id = '$id'");
$image = $image->fetch_assoc();
$image = $image['photo'];

 echo $image;
 ?>
