Celestial Waves One-Shot Collection What is the Celestial Waves AU?

The Celestial Waves AU is a TSAMS AU where the cast are mermaids, blog posts are written in a arg style by employees of the Celestial Waves Project, a group lead by The Creator and his husband, Dr. Newton, that observes the Decidit Astrum (the merr) and you (some rando who has made direct contact with them) by extension.

Basically, tsams au where the creator is a fucked up marine biologist and the Decidit Astrum is a man made species created by him

Subject References

|| Sun || Moon || Earth || Lunar || Eclipse || Solar || KrillCode || BloodMoon || 'Frank' || SolarFlare || Jack || Gemini ||Your Boat || You ||

Misc

|| The Creator|| Dr.Newton || Relationship chart || The Newton Star || Star Fragments || Decidit Astrum Origins ||The CelestialFall||

Feel free to send asks about the AU or questions directed to the AU characters themselves (stares at you with my big round eyes)! You can also send requests for future one-shots

More info below cut

Notes

Alternate dimention characters do exist but in seperate shoals, they are treated as different members of the same species by the characters instead of alternate versions (e.g. Eclipse and Solar do not see each other as alternate versions of each other, just that they look really similar)

I have the curse of a somewhat cute artstyle, almost all of the characters are considered to be both terrifing and etherial even though I make them little guys.

Everyone is alive or otherwise present

Dr. Newton is NOT the trashcan man or whatever his name is

In character posts are tagged with #Celestial Waves Project and out of character posts are tagged with #Celestial Waves Overseer

I will also occasionally post/reblog non au stuff for world building/atmostphere tagged with _posting or [charactername]core if a specific post reminds me of one of the characters

(I do not know the first thing about fish biology or boat living I am sorry)

Rules and Boundaries

Suggestive asks are okay but straight up NSFW asks are not (I am 17), the same applies to art and writing requests

SQL Injection

perhaps, the direct association with the SQLi is:

' OR 1=1 -- -

but what does it mean?

Imagine, you have a login form with a username and a password. Of course, it has a database connected to it. When you wish a login and submit your credentials, the app sends a request to the database in order to check whether your data is correct and is it possible to let you in.

the following PHP code demonstrates a dynamic SQL query in a login from. The user and password variables from the POST request is concatenated directly into the SQL statement.

$query ="SELECT * FROM users WHERE username='" +$_POST["user"] + "' AND password= '" + $_POST["password"]$ + '";"

"In a world of locked rooms, the man with the key is king",

and there is definitely one key as a SQL statement:

' OR 1=1-- -

supplying this value  inside the name parameter, the query might return more than one user.

most applications will process the first user returned, meaning that the attacker can exploit this and log in as the first user the query returned

the double-dash (--) sequence is a comment indicator in SQL and causes the rest of the query to be commented out

in SQL, a string is enclosed within either a single quote (') or a double quote ("). The single quote (') in the input is used to close the string literal.

If the attacker enters ' OR 1=1-- - in the name parameter and leaves the password blank, the query above will result in the following SQL statement:

SELECT * FROM users WHERE username = '' OR 1=1-- -' AND password = ''

executing the SQL statement above, all the users in the users table are returned -> the attacker bypasses the application's authentication mechanism and is logged in as the first user returned by the query. 

The reason for using  -- - instead of -- is primarily because of how MySQL handles the double-dash comment style: comment style requires the second dash to be followed by at least one whitespace or control character (such as a space, tab, newline, and so on). The safest solution for inline SQL comment is to use --<space><any character> such as -- - because if it is URL-encoded into  --%20- it will still be decoded as -- -.

Semi-related if you ever used a Carrd and bumped into the 50 element limit: do yourself a favour, fork a minimalist Jekyll repository on GitHub and pick up Markdown. Quite a few of them work as soon as you fork it without any further tinkering, you just add your .md files in the _posts directory or in the main directory with the layout stuff. It uses Liquid templating which can be advanced but again, there's plenty of inserts other people have written for you to use.

Wenn der WebViewer plötzlich leer bleibt: Daten lieber per Session-ID statt über WebViewer.SetHTML

Nach etlichen Projekten mit WebViewer-Integration in FileMaker kennt man das: Eine aufwendig generierte HTML-Darstellung wird in eine Variable geschrieben und mit WebViewer.SetHTML in das Layout eingebunden. Doch irgendwann, meist nach einem Update, einer Layoutänderung oder schlicht durch zu große Datenmengen, bleibt der WebViewer plötzlich leer. Keine Fehlermeldung, kein Hinweis. Die Lösung, die sich in meinem Fall bewährt hat. Statt den HTML-Inhalt direkt aus FileMaker in eine Variable zu übergeben, wird dieser über ein PHP-Skript auf dem Server dynamisch aufgebaut. FileMaker überträgt die Inhalte per POST, der Server speichert sie mit einer eindeutigen Session-ID in einer temporären Datei. Anschließend ruft FileMaker einfach https://meinserver.de/tour.php?session=ava_65df75dca14f8 auf und der WebViewer lädt die fertige Darstellung wie jede andere Webseite auch. Vorteile dieser Methode: – Kein Zeichenlimit oder Kodierungsproblem in FileMaker-Variablen – HTML, CSS und JavaScript können deutlich umfangreicher sein – Die Darstellung ist im Browser direkt testbar (z. B. mit ?debug=1) – Die Daten sind temporär gespeichert und nach Ablauf automatisch gelöscht Vorgangsweise: Daten werden per POST an den Server gesendet, dort in einer temporären JSON-Datei abgelegt und über eine Session-ID abrufbar gemacht. Der WebViewer muss dann nur noch die Session-ID in der URL übergeben. Der Server liefert die fertige Darstellung. Also eigentlich wie mit dem Browser. Dieser Code-Bereich ist das Herzstück für den POST-Empfang. Er übernimmt Daten aus FileMaker, speichert sie temporär als JSON-Datei und gibt eine eindeutige Session-ID zurück. Wenn sonst nach dem FileMaker Befehl -Aus URL einfügen- eine ganze HTML-Strucktur zurückkommt, bekommen wir nur noch die Session-ID zurück. Diese wird dann nur noch an die eigentliche URL der PHP-Datei gehangen. Z.B. so: https://deinserver.de/tour_post_neu.php?session=id123456.7654321.

// POST: Daten speichern und Session-ID zurückgeben if ($_SERVER['REQUEST_METHOD'] === 'POST') { $postData = array_map('trim', $_POST); $sessionId = uniqid('ava_', true); $sessionDir = __DIR__ . '/sessions/'; if (!file_exists($sessionDir)) mkdir($sessionDir, 0755, true); file_put_contents($sessionDir . $sessionId . '.json', json_encode([ 'data' => $postData, 'created' => time() ])); echo $sessionId; exit; }

Nun wird diese URL (https://deinserver.de/tour_post_neu.php?session=id123456.7654321) im WebViewer aufgerufen. Für die Verarbeitung ist dieser Teil zuständig.

if (isset($_GET['session'])) { $sessionFile = __DIR__ . '/sessions/' . $_GET['session'] . '.json'; if (file_exists($sessionFile)) { $sessionData = json_decode(file_get_contents($sessionFile), true); if (time() - $sessionData['created'] > 3600) { unlink($sessionFile); echo "Session abgelaufen"; exit; } $postData = $sessionData['data']; // hier folgt die HTML-Ausgabe } }

Discuz! 发帖回复字数设置

在 Discuz! 论坛中，设置发帖或回复的字数限制主要涉及帖子内容的最大字数和标题的字数限制。以下是具体设置方法，适用于大多数 Discuz! 版本（如 X3.2、X3.4 等）。请注意，修改前建议备份相关文件和数据库，以防出现问题。 一、设置帖子内容最大字数 Discuz! 允许通过后台设置帖子内容的字节数限制（1 汉字 ≈ 3 字节，UTF-8 编码）。 进入后台： 登录 Discuz! 论坛后台。 导航到：全局 → 用户权限。 修改最大字数： 找到 帖子最大字数(字节) 设置项。 默认值通常为 10000 字节（约 3333 汉字）。可根据需要修改，例如改为 64000 字节（约 21333 汉字）。 修改后点击 提交 保存。 效果： 此设置适用于所有版块的帖子内容（包括主题和回复），限制用户输入的最大字节数。 参考来源：, 二、设置帖子标题字数限制 Discuz! 默认帖子标题限制为 80 个字符（UTF-8 编码下，1 汉字 ≈ 3 字符），但可以通过修改代码调整最大或最小字数。

设置标题最大字数 要增加标题的最大字符限制（例如从 80 字符改为 180 字符），需修改数据库和前端代码： 修改数据库： 登录 MySQL 数据库（建议先备份数据库）。 执行以下 SQL 语句，将相关表的标题字段长度改为 180 字符： sql ALTER TABLE pre_forum_post CHANGE subject subject VARCHAR(180) NOT NULL; ALTER TABLE pre_forum_rsscache CHANGE subject subject CHAR(180) NOT NULL; ALTER TABLE pre_forum_thread CHANGE subject subject CHAR(180) NOT NULL; 注意：pre_ 是 Discuz! 数据库表前缀，需根据实际配置调整。 修改前端代码： 打开文件：static/js/forum_post.js。 查找以下代码： javascript } else if(mb_strlen(theform.subject.value) > 80) { showError('您的标题超过 80 个字符的限制'); return false; } 将 80 改为需要的数值，例如 180： javascript } else if(mb_strlen(theform.subject.value) > 180) { showError('您的标题超过 180 个字符的限制'); return false; } 保存文件并上传到服务器。 可选：修改模板文件： 备份并打开文件：template/default/forum/post_editor_extra.htm。 查找类似 mb_strlen(theform.subject.value) > 80 的代码，将 80 改为 180。 保存并上传。 参考来源：,,

设置标题最小字数 若需限制标题的最小字数（例如至少 10 个汉字 ≈ 20 字节），可修改前端代码： 打开文件：static/js/forum_post.js。 找到以下代码： javascript } else if(mb_strlen(theform.subject.value) > 80) { showError('您的标题超过 80 个字符的限制'); return false; } 在其下方添加以下代码： javascript else if(mb_strlen(theform.subject.value) < 20 && mb_strlen(theform.subject.value) > 0) { showError('您的标题不足10个汉字的字符数，请您将您要表达的主题表述清楚，然后再提交！'); return false; } 说明：20 表示 20 字节（约 10 汉字），可根据需要调整。 保存文件并上传。 参考来源： 三、设置回帖字数限制 Discuz! 原生系统中没有直接设置回帖（回复）字数限制的后台选项，但可以通过以下方式实现：

利用插件 安装第三方插件，如“帖子标签后台快速添加插件”或“限制重复发帖和回帖插件”，部分插件可能支持自定义回帖字数限制。 插件安装方法： 下载插件并解压到 source/plugin/ 目录。 进入后台 → 插件 → 安装并启用。 根据插件说明配置字数限制。 参考来源：,

自定义代码修改 若无合适插件，可通过修改发帖逻辑实现回帖字数限制： 打开文件：source/module/forum/forum_post.php。 查找处理回复提交的代码段（通常包含 message 字段的处理逻辑）。 添加字数检查逻辑，例如： php if (mb_strlen($_POST['message']) < 30) { // 最小 30 字节，约 10 汉字 showmessage('您的回复内容少于10个汉字，请输入更多内容！'); } 说明：具体代码位置和实现方式可能因版本不同而异，建议由熟悉 PHP 的开发者操作。 保存并上传文件。 参考来源：, 四、其他注意事项 用户组权限： 在 用户 → 用户组 → 编辑 中，检查是否启用了“允许编辑帖子”或“允许使用 HTML 代码”等权限，这些可能影响字数限制的实际效果。 可为不同用户组设置不同的发帖/回帖权限，但字数限制通常全局生效。 版块设置： 在 论坛 → 版块管理 → 编辑 → 帖子选项 中，检查是否启用了“发帖审核”或“允许编辑帖子”，这些设置可能间接影响内容长度管理。 SEO 和用户体验： 设置最小字数限制（如标题或回复）有助于防止灌水和提高 SEO 效果，但过高的限制可能影响用户体验，建议权衡设置。 测试与备份： 修改代码或数据库后，务必在测试环境中验证效果。 确保每次修改前备份数据库和相关文件，避免因错误导致论坛不可用。 参考来源：, 五、常见问题解答 如何取消字数限制？ 对于帖子内容，可在后台将“帖子最大字数”设为 0（表示无限制，但不推荐，可能会导致性能问题）。 对于标题，需修改 forum_post.js 和数据库，将最大字符数设为更大值（如 255）。 不同用户组能否设置不同字数限制？ 原生 Discuz! 不支持为不同用户组设置独立的字数限制，需通过自定义插件或修改 forum_post.php 实现。 修改后不生效怎么办？ 检查是否清除了论坛缓存（后台 → 工具 → 更新缓存）。 确认修改的文件已正确上传到服务器。 检查是否因模板或插件冲突导致设置失效。 六、总结 帖子内容最大字数：通过后台“全局 → 用户权限”直接设置。 标题字数：修改数据库和 forum_post.js 文件，支持最大/最小字数限制。 回帖字数：需借助插件或自定义代码实现。 操作建议：备份文件和数据库，谨慎修改代码，必要时咨询专业开发者。 如果您有具体版本（如 X3.2 或 X3.4）或更详细的需求（如特定版块设置），请提供更多信息，我可以进一步优化答案！

How to Develop a Website Using PHP

How to Develop a Website Using PHP

In today's digital era, websites play a crucial role in business growth and online presence. One of the most widely used server-side scripting languages for web development is PHP (Hypertext Preprocessor). It is open-source, easy to learn, and widely supported by web servers and databases. This guide will walk you through the step-by-step process of developing a website using PHP.

Why Choose PHP for Web Development?

Before diving into the development process, let’s explore some key reasons why PHP is a great choice for website development:

1. Open-Source: PHP is free to use, making it cost-effective for developers.

2. Cross-Platform Compatibility: Runs on Windows, Linux, and macOS without compatibility issues.

3. Database Support: Easily integrates with MySQL, PostgreSQL, and other databases.

4. Scalability: Suitable for both small websites and large-scale web applications.

5. Large Community Support: Extensive documentation and active developer communities for troubleshooting and learning.

Prerequisites for PHP Web Development

To develop a website using PHP, you need the following tools:

1. Text Editor or IDE: VS Code, Sublime Text, or PHPStorm.

2. Local Server: XAMPP, WAMP, or MAMP for running PHP scripts.

3. Database System: MySQL or PostgreSQL for data storage.

4. Web Browser: Chrome, Firefox, or Edge for testing the website.

Step-by-Step Guide to Developing a Website Using PHP

1. Setting Up Your Development Environment

To begin developing a PHP website, follow these steps:

· Install XAMPP (or WAMP/MAMP) to create a local server.

· Using the XAMPP Control Panel, launch Apache and MySQL.

· Navigate to htdocs in the XAMPP directory to store PHP project files.

2. Creating the Project Structure

Organizing your files properly enhances maintainability. A typical PHP project structure:

project-folder/

│-- index.php

│-- config.php

│-- assets/

│   ├── css/

│   ├── js/

│   ├── images/

│-- includes/

│   ├── header.php

│   ├── footer.php

│-- pages/

│   ├── about.php

│   ├── contact.php

│-- database/

│   ├── db_connect.php

3. Writing Your First PHP Script

Create an index.php file and add the following code:

<?php

  echo "Welcome to My PHP Website!";

?>

Save the file and access it in the browser by navigating to http://localhost/project-folder/.

4. Connecting PHP with MySQL Database

To manage dynamic content, connect PHP with a MySQL database.

Create a Database

1. Open phpMyAdmin from XAMPP.

2. Create a new database, e.g., my_website.

3. Add a users table with fields id, name, email, and password.

Database Connection Code (db_connect.php)

<?php

$servername = "localhost";

$username = "root";

$password = "";

dbname = "my_website";

$conn = new mysqli($servername, $username, $password, $dbname);

if ($conn->connect_error) {

    die("Connection failed: " . $conn->connect_error);

}

?>

5. Creating a User Registration System

A simple user registration form using PHP and MySQL.

Registration Form (register.php)

<form method="POST" action="register.php">

  <input type="text" name="name" placeholder="Full Name" required>

  <input type="email" name="email" placeholder="Email" required>

  <input type="password" name="password" placeholder="Password" required>

  <button type="submit" name="register">Register</button>

</form>

Handling User Registration (register.php)

<?php

include 'database/db_connect.php';

if(isset($_POST['register'])) {

    $name = $_POST['name'];

    $email = $_POST['email'];

    $password = password_hash($_POST['password'], PASSWORD_BCRYPT);

    $sql = "INSERT INTO users (name, email, password) VALUES ('$name', '$email', '$password')";

    if ($conn->query($sql) === TRUE) {

        echo "Registration successful!";

    } else {

        echo "Error: " . $conn->error;

    }

}

?>

6. Implementing User Login System

Login Form (login.php)

<form method="POST" action="login.php">

  <input type="email" name="email" placeholder="Email" required>

  <input type="password" name="password" placeholder="Password" required>

  <button type="submit" name="login">Login</button>

</form>

Handling Login Authentication (login.php)

<?php

session_start();

include 'database/db_connect.php';

if(isset($_POST['login'])) {

    $email = $_POST['email'];

    $password = $_POST['password'];

    $result = $conn->query("SELECT * FROM users WHERE email='$email'");

    $user = $result->fetch_assoc();

    if(password_verify($password, $user['password'])) {

        $_SESSION['user'] = $user;

        echo "Login successful!";

    } else {

        echo "Invalid credentials!";

    }

}

?>

7. Adding Navigation and Styling

· Use Bootstrap or CSS frameworks to improve UI.

· Include a header.php and footer.php for better navigation.

8. Deploying the PHP Website

Once development is complete, deploy your PHP website using:

· Shared Hosting with cPanel for easy management.

· Cloud Hosting (AWS, DigitalOcean) for high performance.

· Domain & SSL Certificate for a secure and professional website.

Conclusion

Developing a website using PHP is an efficient way to create dynamic and interactive websites. By following this step-by-step guide, you can build a PHP-based website from scratch, implement database interactions, user authentication, and deploy your project successfully. Start your PHP development journey today and create powerful web applications!

SQL Injection Risks & Protection for OpenCart Sites 🚨

Protecting Your OpenCart Store from SQL Injection Attacks

SQL Injection (SQLi) attacks can seriously compromise an eCommerce store. OpenCart users, take note! In this quick guide, we’ll look at what SQL injection is, see some vulnerable code examples, and share coding techniques to keep your store secure.

What’s an SQL Injection (SQLi)?

SQL injection occurs when a hacker manipulates SQL code within a form field, URL, or other input method, often bypassing authentication or accessing sensitive data. An SQLi attack can trick OpenCart into sharing sensitive user data, including passwords and order details.

Here’s an example of vulnerable code in PHP:

php

// Unsafe SQL query example $user = $_POST['username']; $pass = $_POST['password']; $query = "SELECT * FROM users WHERE username = '$user' AND password = '$pass'";

Hackers can easily manipulate this by entering something like ‘ OR 1=1 -- into the username field, granting them access without a password.

Secure Coding Practices: How to Protect Against SQL Injection

Use Prepared Statements: A powerful way to protect against SQLi is to use prepared statements with bound parameters. This stops SQL commands from being injected into your code.

Example of Safe Code:

php

// Using prepared statements $stmt = $db->prepare("SELECT * FROM users WHERE username = ? AND password = ?"); $stmt->bind_param("ss", $user, $pass); $stmt->execute();

This code uses placeholders (?) to avoid direct injection, ensuring only validated data is processed.

Advanced Tips:

Sanitize Inputs: Check all user input to filter out malicious code.

Use ORM Libraries: Object Relational Mapping libraries, like Doctrine, help limit SQLi risks.

Restrict Database Permissions: Set minimal access rights for database users.

Tools for Securing Your Site

Using vulnerability scanners can give you insight into potential weaknesses on your OpenCart store.
