使用< img src ="">图片显示>不工作 [英] Image display with <img src=""> not working

问题描述

:我发现我有一个权限错误。无论出于何种原因，我没有许可从图像文件夹中获取图像...... * b

几天前，我问了关于上传图像的这个问题，满意的。我将它集成到我的网站，它没有任何问题。

图片 - 上传没有响应，无法访问$ _FILES

我现在遇到的问题是我无法以任何形式或形式检索图像。我试图打开它们，并设置它们阅读，与fopen（$ image，r）。我尝试了更复杂的东西，比如将图像加载回数据库......然后它让我感觉到anwser很简单。

我可以在我的图片文件夹中看到图片，所以应该没问题。但它不= =（$ / b>

---

这是PHP脚本的一次，

  if（isset（$ _ FILES ['fupload']））
 {
 
 $ max_size = mysql_real_escape_string（strip_tags（$ _ POST [ 'MAX_FILE_SIZE']））; 
 $ file = $ _FILES ['fupload'] ['name']; 
 
 if（isset（$ max_size）&&！empty（$ （$ file））{
 $ file_type = $ _FILES ['fupload'] ['type']; 
 $ tmp = $ _FILES ['fupload'] ['' tmp_name']; 
 $ file_size = $ _FILES ['fupload'] ['size']; 
 
 $ allowed_type = array（'image / png'，'image / jpg'，' （$ file_type，$ allowed_type））{
 if（$ file_size< $ max_size）{
 $ path ='images /'.$ file; 
 
 $ move = move_uploaded_file（$ tmp，$ path）; 
 $ sql =UPDATE info.profile SET Profile_pic ='。$移动。'，pic_name ='。$ file。'WHERE Nick ='。$ _ SESSION ['Nick']。'; 
 mysql_query（$ sql）或者死（Error：.mysql_error（））; 
 $ _SESSION ['pic'] = $ path; 
 
 echo图片添加成功:) :) :); 
} 
  

我忽略了所有其他语句，因为它们不相关。以下是应该显示图像的示例。

 < td rowspan = 2 align = center width = 100px> < img src =<？php $ _SESSION ['pic'];？> 
 alt =这是图片，如果它工作正常!!> < / TD> 
  

当然，alt是一个小挑逗，但我已经尝试了一切，获取替代文字显示。有时会显示一个坏图片图标（例如，当您在允许图片显示之前在电子邮件中打开图片时）

当我回显路径时，它显示正确路径，就像我在手动输入时输入的内容一样。我在DB和会话中存储路径的原因是因为图像是配置文件图像，应该只显示该用户...不希望其他用户拥有其他用户图像作为他们的个人资料图=

解决方案

相对于当前目录，路径应该是。你有没有检查过它？

试试在 Rohit 评论中给出的答案。

 < img src ='<？php echo $ _SESSION ['pic']; >'/> 
  

EDIT :: I found out that i am having a permission error. For whatever reason i dont have "permission" to grab the image from the images folder ... *

a few days ago i asked this question about uploading images and was very satisfied with the anwser. I integrated it into my site and it works no problem.

Image - Upload not responding, no access to $_FILES

The problem i am having now is i cannot retrieve the images in any way shape or form. I have tried opening them and setting them to read, with fopen($image, r). I tried even more complicated things like loading the image back into a database ... then it hit me that the anwser is simple.

I CAN see the image in my images folder, so should work no problem. But it doesnt =(

Here is the PHP script one more time,

if (isset($_FILES['fupload'] ))
{

$max_size = mysql_real_escape_string(strip_tags($_POST['MAX_FILE_SIZE']));
$file = $_FILES['fupload']['name'];

if(isset($max_size) && !empty($max_size) && !empty($file)) {
    $file_type = $_FILES['fupload']['type'];
    $tmp = $_FILES['fupload']['tmp_name'];
    $file_size = $_FILES['fupload']['size'];

    $allowed_type = array('image/png', 'image/jpg', 'image/jpeg', 'image/gif');

    if(in_array($file_type, $allowed_type)) {
        if($file_size < $max_size) {
            $path ='images/'.$file;

         $move = move_uploaded_file($tmp, $path);
         $sql = "UPDATE info.profile SET Profile_pic='".$move."', pic_name='".$file."' WHERE Nick='".$_SESSION['Nick']."'"; 
         mysql_query($sql) or die ("Error: " .mysql_error());
         $_SESSION['pic'] = $path;

        echo "image added successfully :) :) :) ";
        }

I left out all the else statements, since they are not relevent. The folowing is an example of where the image should be displayed.

<td rowspan=2 align=center width=100px> <img src="<?php $_SESSION['pic']; ?>"
 alt="Here would be the picture, if it was working !!"> </td>

The alt is a small teaser of course, but i have tried everything and with the current script i managed to get the alt text to display. Sometimes a "bad image" icon displayes (like when you open images in an email before allowing images to be displayed)

When i echo the path it shows the "right" path, just like i would enter when manualy giving it in. The reason i store the path in DB and in a session is because the image is a profile image and should only be displayed for THAT user ... wouldnt want other users having other images as their profile pic. =)

解决方案

The path should be relative to the current directory. Have u checked it ?

Try the answer given in comment by Rohit.

<img src='<?php echo $_SESSION['pic']; ?>' />
