How can I make each board have different banners?

[Beijingvinc]

I tried in a pretty dumb way — I modified the HTML of the boards, but of course, that gets updated when a thread is created. I really hope you can help me, because I really don't want the entire site to have the same banners

ask grok.com or chatgpt.com for simple things like that, either should be able to instantly make a couple lines of code for your customized version. It is silly to ask questions in places like here and be ignored for weeks, when Ai can give you instant answers and follow up answers to follow up questions.

I tried that and it doesn't give a real solution.

it codes entire boards in Rust for me, so it should be able to answer a simple question for you. You have to ask the right questions, sometimes you have to feed it a file to look at- best of luck. Not sure why you would want to tinker with vichan. Ai can make a php board that runs off php 8.4.8 , while vichan has been struggling to barely keep up with non deprecated versions of php, which is inept and silly and dangerous for security. Php was cool in about 1990. Today a node js board like lynxchan or js chan is a step above php, a golang board like siracha or usagi riesen is above node js, and a well coded ib in Rust is objectively superior to them all. Ai can make you a very tiny codebase full featured ib - customized to how you want to do things...while a bloated ib like vichan is laughable by comparison. And also, while you claim you asked ai how to do it, if you did not feed it b.php to look at, you did not even try. Each board can have its own b.php, so each board has its own banners.

1990? bro imgboards are 2000 shit no 1990

the first hotwheels meme appeared in ancient times, on a pyramid writing in egypt. I think that was technically the first imageboard meme.

??? stop trolling

With the current b.php is not possible.

Edit: Custom code I run
each board has their own folder inside static/banners/ and a sub priority which gets shown every X on all boards.

<?php

namespace Vichan\Service;

use Vichan\Data\Driver\CacheDriver;

class BannersService {
	private const BANNERS_DIR = 'static/banners/%s/';
	private const PRIORITY_DIR = 'static/banners_priority/';
    private const ALLOWED_EXT = ['jpg', 'jpeg', 'png', 'gif', 'webp'];
	private const UKKO = 'overboard';

	public function __construct(private readonly CacheDriver $cache) {
	}

	private function getFilesInDirectory(string $dir): array {
		if (!\is_dir($dir)) {
			$dir = self::PRIORITY_DIR;
		}

		$cacheKey = "files_{$dir}";
		$listFiles = $this->cache->get($cacheKey);

		if (!$listFiles) {
			$listFiles = \array_diff(\scandir($dir, SCANDIR_SORT_NONE), ['.', '..']);
			$listFiles = \array_filter($listFiles, fn ($file) => \is_file($dir . $file) && $this->isImage($file));
			$this->cache->set($cacheKey, $listFiles, 10800);
		}

		return $listFiles;
	}

	private function isImage(string $fileName): bool {
		$extension = \strtolower(\pathinfo($fileName, PATHINFO_EXTENSION));
		return \in_array($extension, self::ALLOWED_EXT, true);
	}

	private function serveRandomBanner(string $dir, array $files): void {
		if ($files === []) {
			\http_response_code(404);
			exit;
		}

		$name = $files[\array_rand($files)];
		$filePath = $dir . $name;

		if (!\is_file($filePath) || !\is_readable($filePath)) {
			\http_response_code(404);
			exit;
		}

		$ext = \pathinfo((string) $name, PATHINFO_EXTENSION);
		$lastModified = \filemtime($filePath);
		$etag = \md5_file($filePath);

		\header("Content-Type: image/{$ext}");
		\header("Content-Length: " . \filesize($filePath));
		\header("Cache-Control: public, max-age=" . (60 * 60 * 24 * 30 * 6)); // 6 months
		\header("ETag: \"$etag\"");
		\header("Last-Modified: " . \gmdate('D, d M Y H:i:s', $lastModified) . ' GMT');
		\header("X-Content-Type-Options: nosniff");

		$ifModifiedSince = $_SERVER['HTTP_IF_MODIFIED_SINCE'] ?? '';
		$ifNoneMatch = $_SERVER['HTTP_IF_NONE_MATCH'] ?? '';

		if (
			(!empty($ifModifiedSince) && \strtotime((string) $ifModifiedSince) === $lastModified) ||
			(!empty($ifNoneMatch) && \trim((string) $ifNoneMatch) === $etag)
		) {
			\header("HTTP/1.1 304 Not Modified");
			exit;
		}

		\readfile($filePath);
		exit;
	}

	public function serve(string $board): void {
		if (!\getBoardInfo($board)) {
			$board = self::UKKO;
		}

		$priorityFiles = $this->getFilesInDirectory(self::PRIORITY_DIR);
		$bannerDir = \sprintf(self::BANNERS_DIR, $board);
		$bannerFiles = $this->getFilesInDirectory($bannerDir);

		$usePriority = $priorityFiles !== [] && (\mt_rand(0, 3) === 0 || $bannerFiles === [] || $board === self::UKKO);

		if ($usePriority) {
			$this->serveRandomBanner(self::PRIORITY_DIR, $priorityFiles);
		} else {
			$this->serveRandomBanner($bannerDir, $bannerFiles);
		}
	}
}

@perdedora yes, i would imagine feeding b.php to ai could do a lot, since the app already calls b.php , all ai would have to do is modify b.php . These dam newbs don't listen tho. :)

how i make that works

What I did is really easy.

simply add configs like

$config[bannerlist_board]

add an array for each board there like
'bb' => 'boobsbanner.png' etc

then go to b.php I think?

<?php
require 'inc/bootstrap.php';
$dir = "static/banners/";
$files = scandir($dir, SCANDIR_SORT_NONE);
$images = array_diff($files, ['.', '..']);
 
$board = $_GET['board'] ?? null;

if ($board && !empty($config['bannerlists']) && isset($config['bannerlist_board'][$board])) {
    $allowed_banners = $config['bannerlist_board'][$board];
    $images = array_values(array_intersect($images, $allowed_banners));
}

 
if (empty($images)) {
    exit;
}

 
$name = $images[array_rand($images)];

 
$fp = fopen($dir . $name, 'rb');
header('Cache-Control: no-cache, no-store, must-revalidate');
header('Pragma: no-cache');
header('Expires: 0');
$fstat = fstat($fp);
header('Content-Type: ' . mime_content_type($dir . $name));
header('Content-Length: ' . $fstat['size']);
// dump the picture and stop the script
fpassthru($fp);
exit;
?>

copypaste it

in config its like this

$config['bannerlists'] = true;
$config['bannerlist_board'] = [
    'bb' => ['bbb.jpg'], 
    'qa' => ['default.png'],
  'pol' => $ban1,
  'int' => $ban1,
];

Hope this helps, i only today got my github account back. forgot its email for like months

Create a file as inc/Service/BannersService.php, edit inc/context.php to include the service like the rest of them, and edit b.php to this:

<?php

use Vichan\Service\BannersService;

require_once 'inc/bootstrap.php';
use function Vichan\build_context;

try {
	$board = htmlspecialchars($_GET['board'], ENT_QUOTES, 'UTF-8');
	$ctx = build_context($config);
	$banners = $ctx->get(BannersService::class);
	$banners->serve($board);
} catch (InvalidArgumentException) {
	http_response_code(400);
	exit;
}

for every single board, how bout the devs have every board call a php file that does nothing - and then anyone can use that extra php file to customize. Especially since Ai is here, ai can poop out any script someone needs! That way it would be leveraging the modern times of ai with vichan.

I don’t know if I’m just dumb, but honestly, I don’t understand a damn thing. I did what the first quoted post says, but it doesn’t work well because it shows everything as global instead of displaying the banners on different boards. And as for the second quoted post, honestly, I don’t understand it at all
