 Posted: Mon Jan 05, 2004 9:37 pm Post subject: Thumbnail Uploads |
 |
|
Here's another nice mod (although it is definitely more like a hack) for your b2 blog. This hack modifies the uploads popup so that you can do two files at a time if you want to have a thumbnail point to a larger main image. The nice thing about the hack is instead of uploading two files and then hand-writing HTML to do the popup, it does it all for you! We use this hack to do thumbnail popups at DIY Games and it seems to work well.
We got rid of the old b2upload.php file and made an entirely new one. Also we don't have alot of duplicate images, so I removed the part of the file upload where it confirms that you want to rename duplicate files. Instead, this script renames them by default.
| Code: | <?php
/* b2 File Upload - original hack by shockingbird.com */
/* modified by VOLTMAN! to do thumbnails */
$standalone="1";
require_once("./b2header.php");
if ($user_level < 3) //Checks to see if user has logged in
die ("Cheatin' uh ?");
if (!$use_fileupload) //Checks if file upload is enabled in the config
die ("The admin disabled this function");

To use this is simple. If you have an image that is NOT a thumbnail link, only fill in the top filename and description. If you have an image that IS a thumbnail link, fill in the top filename with the thumbnail image, fill in a description, then fill in the bottom filename with the main/large image. Nice!

hi just a litte problem with this...
| Code: | Warning: move_uploaded_file(/home/csbbshf/public_html/b2/images/mon.jpg): failed to open stream: Permission denied in /home/csbbshf/public_html/b2/b2upload.php on line 183
Warning: move_uploaded_file(): Unable to move '/tmp/phpOmpoI2' to '/home/csbbshf/public_html/b2/images/mon.jpg' in /home/csbbshf/public_html/b2/b2upload.php on line 183
1: Couldn't Upload Your File to /home/csbbshf/public_html/b2/images/mon.jpg. |
Any suggestions? Thanks...
I had the line | Code: | # accepted file types, you can add to that list if you want
# note: add a space before and after each file type
# example: $fileupload_allowedtypes = ' jpg gif png ';
$fileupload_allowedtypes = ' jpg gif png mpg mov '; |
in my b2 config and i changed it to delet the mpg and mov filetypes... didnt do anything. |
