I run a simple image host Mr Image host.com

When a user uploads an image a thumbnail is automatically generated in the folder /thumbs and the main image is in the folder /uploads.

My site runs on a simple CMS, and I was wondering how I could view from my admin panel all the images in these folders at one time, and delete any if necessary.

Thanks for your help :)

it's basic, not very secure, and i'm sure you would be able to style it yourself...

ok... if you want the image as well...

Code: [ Select ]

  echo "<font color=\"blue\">".$_GET['delete']." was deleted</font><br>\n";
 } else {
  echo "<font color=\"red\">".$_GET['delete']." could not be deleted</font><br>\n";

  echo "<tr><td align=\"center\"><img src=\""$baseDir.$slash.$data."\"><br>".$data."</td><td><a href=\"".$base_file."?delete=".$data."\">Delete</a></td></tr>\n";
 }
}

  14. );
  16. // Delete File
  17. $pathinfo = pathinfo($baseDir.$slash.$_GET['delete']);
  18. if($_GET['delete'] && array_search($pathinfo['extension'], $ext)) {
  19.  if(unlink($baseDir.$slash.$_GET['delete'])) {
  20.   echo "<font color=\"blue\">".$_GET['delete']." was deleted</font><br>\n";
  21.  } else {
  22.   echo "<font color=\"red\">".$_GET['delete']." could not be deleted</font><br>\n";
  23.  }
  24. }
  26. // Get Directory
  27. $dir = dir($baseDir);
  29. // Start Table
  30. echo "<table>\n";
  32. // Start Array
  33. while(false !== ($data = $dir->read())) {
  34.  $pathinfo = pathinfo($baseDir.$slash.$data);
  35.  if(array_search($pathinfo['extension'], $ext) && !is_dir($baseDir.$slash.$data)) {
  36.   echo "<tr><td align=\"center\"><img src=\""$baseDir.$slash.$data."\"><br>".$data."</td><td><a href=\"".$base_file."?delete=".$data."\">Delete</a></td></tr>\n";
  37.  }
  38. }
  40. // End Table
  41. echo "</table>\n";


and again, the styling of this whole thing is up to you...

OK two errors:

It seems to work, there are image placeholders, but no images. When I view the 'location' of the image, i get folders added like this:
Quote:
http://www.mrimagehost.com/home/mrimageh/public_html/uploads/%5C3001green_3Q4C1t.gif


Also, when deleting an image, this is the error I recieve:
Quote:
Warning: unlink(/home/mrimageh/public_html/uploads/\3001green_3Q4C1t.gif): No such file or directory in /home/mrimageh/public_html/test.php on line 20


Another note: I replaced \\images\\ with /uploads/ is that OK?

the only reason that the slashes can be differed is because of the difference between how windows and linux works. In this case it looks ok to me... except for the second example - uploads/\3001green_3Q4C1t.gif - the variable $slash needs to be changed to "/"

OK fixed that problem.

but the images still dont display. For example, the script thinks an image is stored here:
Quote:
http://www.mrimagehost.com/home/mrimageh/public_html//uploads////3001green_3Q4C1t.gif


When its actually stored:
Quote:
http://www.mrimagehost.com/uploads/3001green_3Q4C1t.gif


:(

for your case, replace the existing part of the code with this:-
Code: [ Select ]
// Start Array
while(false !== ($data = $dir->read())) {
 $pathinfo = pathinfo($baseDir.$slash.$data);
 if(array_search($pathinfo['extension'], $ext) && !is_dir($baseDir.$slash.$data)) {
  echo "<tr><td align=\"center\"><img src=\"/upload/".$data."\"><br>".$data."</td><td><a href=\"".$base_file."?delete=".$data."\">Delete</a></td></tr>\n";
 }
}
  1. // Start Array
  2. while(false !== ($data = $dir->read())) {
  3.  $pathinfo = pathinfo($baseDir.$slash.$data);
  4.  if(array_search($pathinfo['extension'], $ext) && !is_dir($baseDir.$slash.$data)) {
  5.   echo "<tr><td align=\"center\"><img src=\"/upload/".$data."\"><br>".$data."</td><td><a href=\"".$base_file."?delete=".$data."\">Delete</a></td></tr>\n";
  6.  }
  7. }

That works great :)

One more question - how would I restrict the size of the images?

Thanks so much for your help Vincent.

Hello,

I am having problems with this script.

It does not display the images.

Do you have any solutions please.

the code i have is:
PHP Code: [ Select ]
<?php

 3 => "gif",
 4 => "bmp",
 5 => "png"
);
 
// Delete File
$pathinfo = pathinfo($baseDir.$slash.$_GET['delete']);
if($_GET['delete'] && array_search($pathinfo['extension'], $ext)) {
 if(unlink($baseDir.$slash.$_GET['delete'])) {
  echo "<font color=\"blue\">".$_GET['delete']." was deleted</font><br>\n";
 } else {
  echo "<font color=\"red\">".$_GET['delete']." could not be deleted</font><br>\n";
