[PHP/OOP] 4chan image downloader V2 - RaGEZONE

Pieman · 01-24-2009

This is the next version of 4chan Image downloader I've added a gallery which let's you select which images you want to download. So you don't accidentally download 20 furry porn wallpapers to your server.

Requirements:

PHP 4.0 or higher (5.0 or higher recommended)
A web server which let's you edit ini settings.

Screenshots:

http://forum.ragezone.com/attachment...v2-gallery.jpg

How to use:

Put the script anywhere on your web server, call it "4chan_images.php" then create a directory called "images" (This can be changed). Then run the script and everything should be self-explanatory.

Script:

PHP Code:

  <?php
error_reporting(0);

class image_downloader { 

    public $url;
    
    protected function get_source() {
    
        if(($source = @file_get_contents($this->url)) == false) {
        
            die("Could not open thread.");
        
        }
    
        return $source;

If you encounter any bugs, please post them here and I'll try to fix them.

10-10-09: Updated the script, it now works again with all boards. It now also downloads the first image of every thread. Something the previous script didn't. Sorry it took so long.

Thank you, kind sir!

Horizon · 02-01-2009

Yay. Now I can has my CP without going to 4chan!

RastaLulz · 02-25-2009

EDIT:
I get this error (cut most of it out, as it just keeps going):

Spoiler:

I've tried it on localhost, and my webhost, neither work.

Mr.Lucifer · 02-26-2009

It's very nice.

I got the same error as you, Rasta. I can't remember exactly how I fixed it but it had something to do with PHP permissions... Either that or I installed another webserver software, WAMP that is.

It seems php can't open the folder where the images are saved in. Try to chmod the folder to 777. If that doesn't work change

PHP Code:

  while(($handle_internal = fopen("http://forum.ragezone.com/images/".rand(0000000000001,9999999999999).".$extension", "x+"))== false)

on line 74 to

PHP Code:

  while(($handle_internal = fopen("".rand(0000000000001,9999999999999).".$extension", "x+"))== false)

This will save all the images in the same folder as the script is located.

As Mr. Lucifer said, it has to do something with permissions. I'm unsure how to fix it though, other than the methods I named above.

Thanks, it now works perfectly.

Also, when I tried to chmod it to 777 yesterday, it gave me the 500 error.

But anyways, that fix worked.

This is probably a small problem I keep getting.

Code:

Notice: Undefined variable: i in C:\wamp\www\IMAGES\4chan_images.php on line 23

Notice: Undefined variable: images_array in C:\wamp\www\IMAGES\4chan_images.php on line 31
0 image(s) not saved.

Whats that mean?
Theres no images? o.O

It's just an empty variable. Just add error_reporting(1); add the top of the file and it should be fixed.

Or better yet, add

PHP Code:

   $i = 0;

under

PHP Code:

  $source = $this->get_source();

On line 19.

Like a script that downloads all images from a CSS file? That does sound useful indeed... Maybe an idea for my next project.

Actually it's because it says http://forum.ragezone.com/images/ instead of ./images.

If you just replaced the http://forum.ragezone.com part with a [.] it should be fine.

Ragezone glitch hurts sometimes

That glitch is dreadfully annoying yes, though I believe the poster was aware of this.

Rasta your script works fine :)

I've edited everything i need to but check it out:

http://rapidwind.net/4chan/4chan.php

When you enter the URL of the thread it doesn't show any pictures it only shows the download button.

here is what I have in the script:

That's weird lol, when i go on yours it works for me..

I think 4chan changed it's source code around a bit because the script doesn't seem to work anymore. I'll try to fix it as soon as possible.

That would be very much appreciated, as it's alot easier than saving every image one by one.

Horizon · 08-12-2009

Yea, I noticed this didn't work a while ago. I'll probably try fixing it later.

Pieman · 10-10-2009

Updated the first post with the new script. Everything is working as it should now.

I keep getting 0 image(s) was downloaded even though it displays the images and I check them and everything.

The image link is correct and I have tried everything from an abolute path, to a local path.

Okay scratch that I got it working, any way for this to work after you close the window? That way I don't have to wait indefinitely?

Perhaps integrate http://www.phpclasses.org/browse/package/1277.html a process queue?

After you press submit, you can close the window and the script will keep running on your web server.
