We Keep Coding

I want my discord bot to send a random message to a text room given by user [by channel id or channel name]

so what I am trying to do is when a user write a command such as
!setchannel #test or !setchannel 86xxxxxxxxxxxxxxx
then the bot will send the random messages to that channel every certain time.
Note that I did the random messages code but I still stuck on creating the !setchannel command.
I am using discord.js v12.5.3
index.js main file
require('events').EventEmitter.prototype._maxListeners = 30;
const Discord = require('discord.js')
const client = new Discord.Client()
require('discord-buttons')(client);

You'll have to use a database to achieve what you're trying to do
An example using quick.db
const db = require(`quick.db`)
const prefix = "!"
client.on("message", async message => {
if (!message.content.startsWith(prefix)) return;
const args = message.content.slice(prefix.length).trim().split(/ +/g)
const cmd = args[0]
if (cmd === "setchannel") {
let c_id = args[1]
if (!c_id) return message.reply("You need to mention a channel/provide id")
c_id = c_id.replace(/[<#>]/g, '')
if (client.channels.cache.get(c_id)) {
await db.set(`_channel_`, c_id) //Set in the database
} else {
return message.reply("Not a valid channel")
}
}
})
Changes to make in your code
client.on('ready', async () => {
let c_id = await db.get(`_channel_`)
cron.schedule('*/10 * * * * *', () => {
const zkrRandom = zkrList[Math.floor(Math.random() * zkrList.length)]
const zkrEmbed = new Discord.MessageEmbed()
.setTitle('xx')
.setDescription(zkrRandom)
.setFooter("xx")
.setColor('#447a88')
.setAuthor('xx#8752')
client.channels.cache.get(c_id).send(zkrEmbed)
})
})
The above sample of quick.db is just an example
If you're using repl.it, I recommend you to use quickreplit

(node:4044) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'cache' of undefined

I sort of need help here, honestly not sure where I went wrong, here is the full code. I am sort of new, just trying to bring back the mention user and the reason back in a message instead of doing anything with this information.
const { client, MessageEmbed } = require('discord.js');
const { prefix } = require("../config.json");
module.exports = {
name: "report",
description: "This command allows you to report a user for smurfing.",
catefory: "misc",
usage: "To report a player, do $report <discord name> <reason>",
async execute(message, client){
function getUserFromMention(mention) {
if (!mention) return;
if (mention.startsWith('<#') && mention.endsWith('>')) {
mention = mention.slice(2, -1);
if (mention.startsWith('!')) {
mention = mention.slice(1);
}
return client.users.cache.get(mention);
}
}
const args = message.content.slice(prefix.length).trim().split(/ +/);
const command = args.shift().toLowerCase();
const offender = getUserFromMention(args[0]);
if (args.length < 2) {
return message.reply('Please mention the user you want to report and specify a reason.');
}
const reason = args.slice(1).join(' ');
message.reply("You reported",offender,"for reason:", reason)
}
}
If I put no mention, I end up with this
And If I do put a mention
this
I get the above error with no response.

You don't have to create a function to get a mention from a message, you can use the Message.mentions property to get the mentions, check the docs for other info about it.
This should solve your issue.
const { prefix } = require("../config.json");
module.exports = {
name: "report",
description: "This command allows you to report a user for smurfing.",
catefory: "misc",
usage: "To report a player, do $report <discord name> <reason>",
async execute(message, client) {
const args = message.content.slice(1).trim().split(/ +/);
const offender = message.mentions.users.first();
// users is a collection, so we use the first method to get the first element
// Docs: https://discord.js.org/#/docs/collection/master/class/Collection
if (args.length < 2 || !offender.username) {
return message.reply('Please mention the user you want to report and specify a reason.');
}
const reason = args.slice(1).join(' ');
message.reply(`You reported ${offender} for reason: ${reason}`);
}
}

Why are you calling client in a command file if you already started a new instance of a client in your root file? try removing client from the top of the code. Hope that works

discord.js deleting only user messages and bot

I want to make my bot to delete only user's messages in a certain channel and not the bot's. I tried doing it using the code below but it kept on deleting the both the bot's messages and mine.
const Discord = require("discord.js");
const client = new Discord.Client();
const { MessageEmbed } = require("discord.js");
const avalibleFormats = ['png', 'gif', 'jpeg', 'jpg']
client.on("ready", () => {
console.log("I am ready!");
});
client.on("message", message => {
if (message.channel.id == '829616433985486848') {
message.delete();
}
if (message.channel.id !== '829616433985486848') {
return;
}
let image = getImage(message)
if (!image) {
return;
}
let embed = new MessageEmbed();
embed.setImage(image.url)
embed.setColor(`#2f3136`)
message.channel.send(embed)
});
const getImage = (message) => message.attachments.find(attachment => checkFormat(attachment.url))
const checkFormat = (url) => avalibleFormats.some(format => url.endsWith(format))
client.login(token);

Well, you only say that if the channel id is 829616433985486848, delete the message. you should also check if the author is a bot using the message.author.bot property:
const avalibleFormats = ['png', 'gif', 'jpeg', 'jpg'];
const checkFormat = (url) => avalibleFormats.some((format) => url.endsWith(format));
const getImage = (message) => message.attachments.find((attachment) => checkFormat(attachment.url));
client.on('message', (message) => {
const certainChannelId = '829616433985486848';
// if the channel is not 829616433985486848, return to exit
if (message.channel.id !== certainChannelId)
return;
// the rest of the code only runs if the channel is 829616433985486848
const image = getImage(message);
// if author is not a bot, delete the message
if (!message.author.bot)
message.delete();
if (!image)
return;
const embed = new MessageEmbed()
.setImage(image.url)
.setColor('#2f3136');
message.channel.send(embed);
});
Actually, if the message is posted by a bot, you don't even need to run anything in there so you can check that right at the beginning and exit early:
client.on('message', (message) => {
if (message.author.bot || message.channel.id !== '829616433985486848')
return;
const image = getImage(message);
if (image) {
const embed = new MessageEmbed()
.setImage(image.url)
.setColor('#2f3136');
message.channel.send(embed);
}
message.delete();
});
If you want it to work in multiple channels, you can create an array of channel IDs and use Array#includes() to check if the current channel ID is in that array:
client.on('message', (message) => {
const channelIDs = ['829616433985486848', '829616433985480120', '829616433985485571'];
if (message.author.bot || !channelIDs.includes(message.channel.id))
return;
const image = getImage(message);
if (image) {
const embed = new MessageEmbed()
.setImage(image.url)
.setColor('#2f3136');
message.channel.send(embed);
}
message.delete();
});

I'm having issues in Discord.js with functions like client.users.cache.size

Whenever I try to use a function like client.users.cache.size or client.guilds.size, they keep giving me an error like "TypeError: Cannot read property 'guilds' of undefined" or "TypeError: Cannot read property 'cache' of undefined".
I was also trying to use let guilds = client.guilds.cache.array().join('\n') but it also throws the same error.
Command's code:
const Discord = require('discord.js');
module.exports = {
name: 'stats',
description: 'Views the bot\'s stats',
execute(client, message) {
const embed = new Discord.MessageEmbed
.setDescription(`In ${client.guilds.size} servers`)
.setTimestamp()
.setFooter(message.member.user.tag, message.author.avatarURL());
message.channel.send(embed)
}
}
Bot's main file:
const path = require('path');
const fs = require("fs");
const { token, prefix } = require('./config.json');
const Discord = require('discord.js');
const db = require ('quick.db');
const client = new Discord.Client
client.commands = new Discord.Collection();
const isDirectory = source => fs.lstatSync(source).isDirectory();
const getDirectories = source => fs.readdirSync(source).map(name => path.join(source, name)).filter(isDirectory);
getDirectories(__dirname + '/commands').forEach(category => {
const commandFiles = fs.readdirSync(category).filter(file => file.endsWith('.js'));
for(const file of commandFiles) {
const command = require(`${category}/${file}`);
client.commands.set(command.name, command);
}
});
client.on("ready", () => {
console.log(`ready!.`);
console.log(token);
// Activities
const activities_list = [
`Serving Tacos | .help`,
`Preparing Orders | .help`
];
setInterval(() => {
const index = Math.floor(Math.random() * (activities_list.length - 1) + 1);
client.user.setActivity(activities_list[index]);
}, 10000);
});
//Joined Guild
client.on("guildCreate", (guild) => {
const EmbedJoin = new Discord.MessageEmbed()
.setColor('#FFFF33')
.setTitle(`Joined Guild: ${guild.name}!`)
.setTimestamp()
console.log(`Joined New Guild: ${guild.name}`);
client.channels.cache.get(`746423099871985755`).send(EmbedJoin)
});
//Left Guild
client.on("guildDelete", (guild) => {
const EmbedLeave = new Discord.MessageEmbed()
.setColor('#FFFF33')
.setTitle(`Left Guild: ${guild.name}.`)
.setTimestamp()
console.log(`Left Guild: ${guild.name}`);
client.channels.cache.get(`746423099871985755`).send(EmbedLeave)
});
client.on('message', message => {
if (!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).trim().split(/ +/);
const commandName = args.shift().toLowerCase();
const command = client.commands.get(commandName)
|| client.commands.find(cmd => cmd.aliases && cmd.aliases.includes(commandName));
if (!command) return;
if (command.guildOnly && message.channel.type === 'dm') {
return message.reply('I can\'t execute that command inside DMs!');
}
if (command.args && !args.length) {
let reply = `${message.author}, wrong usage`;
if (command.usage) {
reply += `\nThe proper usage would be: \`${prefix}${command.name} ${command.usage}\``;
}
return message.channel.send(reply);
}
try {
command.execute(message, args);
} catch (error) {
console.error(error);
message.reply('there was an error trying to execute that command!');
}
});
process.on("error", () => {
console.log("Oops something happened!");
});
client.login(token);

In your code, client.guilds returns a manager, so you have to use client.guilds.cache.size. The rest of the code works fine.
const Discord = require('discord.js');
module.exports = {
name: 'stats',
description: 'Views the bot\'s stats',
execute(message, args, client) {
const embed = new Discord.MessageEmbed
.setDescription(`In ${client.guilds.cache.size} servers`)
.setTimestamp()
.setFooter(message.member.user.tag, message.author.avatarURL());
message.channel.send(embed)
}
}
In your main bot file you're only passing the message and the args (in this order) to command.execute(). You can add the client too, and update the parameters in your command's code to match this order.
try {
command.execute(message, args, client);
} catch (error) {
...
}

how to separate words in arguments (discord.js)

client.on('message', message => {
if (!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).trim().split(' ');
const command = args.shift().toLowerCase();
if (command === 'say') {
if (!args.length) {
return message.channel.send(`Please tell the bot what to say, ${message.author}`);
}
const { Client, MessageEmbed } = require('discord.js');
const embed = new MessageEmbed()
.setTitle(`${args}`)
.setColor('RED')
message.channel.send(embed);
}
})
but whenever i type !say subscribe today it comes out as subscribe,today
can someone please tell me a way to separate the argument so the commas arent there and its more than one word?

if (command === 'say') {
if (!args.length) {
return message.channel.send(`Please tell the bot what to say, ${message.author}`);
}
let text = args.join(' '); //Join the array of strings with a space to create a text to send
const { Client, MessageEmbed } = require('discord.js');
const embed = new MessageEmbed()
.setTitle(text)
.setColor('RED')
message.channel.send(embed);
}
More on array.join() method here

const Discord = require('discord.js');
const client = new Discord.Client();
const prefix = '!';
client.on('message', (message) => {
let args = message.content.substring(0, prefix.length).split(' ');
let command = args.shift();
});
