Telegram Filter Scripting for Advanced Users

Introduction to Telegram Filter Scripting

Telegram's filter system is a powerful tool for managing the vast amounts of information that can flood your chat groups and channels. For advanced users, the filter command can be scripted to automatically handle messages based on predefined criteria. This guide will walk you through how to set up filters that can automatically respond to specific types of messages, making your Telegram experience more efficient and enjoyable.

Basic Concepts

Filters in Telegram are essentially rules that you set up to automatically respond to messages in your channels and groups. These rules can be based on keywords, patterns, or even specific users. Once set up, filters can automatically delete inappropriate messages, send pre-defined replies, or even forward messages to another group or channel.

Creating a Filter

To create a filter, you first need to set up a basic structure. Here’s a simple example of how you might do this:

bot.on('message', function(msg) {
    if (msg.text.toLowerCase().includes('keyword')) {
        bot.sendMessage(msg.chat.id, 'Response to the keyword');
    }
});

In this script, the bot listens for any message and checks if the message text includes the keyword. If it does, the bot sends a response message.

Adding Conditions

Filters can become more complex by adding conditions. You can specify multiple keywords, use regular expressions, or even check the time of the message. Here’s an example:

bot.on('message', function(msg) {
    if (msg.text.toLowerCase().includes('keyword1') && (msg.text.toLowerCase().includes('keyword2'))) {
        bot.sendMessage(msg.chat.id, 'Response if both keywords are found');
    } else if (msg.text.toLowerCase().includes('keyword3')) {
        bot.sendMessage(msg.chat.id, 'Response if the third keyword is found');
    }
});

Using Filters to Forward Messages

Filters can also be used to automatically forward messages to another chat. This is useful for managing multiple groups or channels. Here’s how to do it:

bot.on('message', function(msg) {
    if (msg.text.toLowerCase().includes('forwardme')) {
        bot.forwardMessage(groupID, msg.chat.id, msg.message_id);
    }
});

In this example, any message containing the word “forwardme” will be forwarded to the chat with the ID groupID.

Deleting Messages with Filters

Filters can also be used to automatically delete inappropriate or irrelevant messages. Here’s an example:

bot.on('message', function(msg) {
    if (msg.text.toLowerCase().includes('spam')) {
        bot.deleteMessage(msg.chat.id, msg.message_id);
    }
});

This script will automatically delete any message containing the word “spam”.

Personalizing Filters

For a more personalized experience, you can create filters that respond to specific users or messages from specific users. Here’s an example:

bot.on('message', function(msg) {
    if (msg.from.id === userID && msg.text.toLowerCase().includes('hello')) {
        bot.sendMessage(msg.chat.id, 'Hello there, how are you today?');
    }
});

In this example, the bot will only respond to the user with the ID userID if they send a message containing the word “hello”.

Conclusion

Telegram’s filter system is a versatile tool that can greatly enhance your experience by automating repetitive tasks and handling messages according to your needs. Whether you’re managing a busy channel or simply trying to keep your personal conversations organized, filters can be incredibly useful. Experiment with different conditions and responses to find the setup that works best for you.
