I have a command which allows users to make the bot to say a message, but I would like it to be able to check whether the user is able to send messages in that channel before it sends it. Currently, I just have it locked to the Manage Messages permission.
Here is the code:
if (message.member.hasPermission("MANAGE_MESSAGES")) {
let msg;
let textChannel = message.mentions.channels.first();
message.delete();
if (textChannel) {
msg = args.slice(1).join(" ");
if (msg === "") {
message.channel.send("Please input a valid sentence/word.")
} else {
textChannel.send(`**Message from ${message.author.tag}:** ${msg}`)
}
} else {
msg = args.join(" ");
if (msg === "") {
message.channel.send("Please input a valid sentence/word.")
} else {
message.channel.send(`**Message from ${message.author.tag}:** ${msg}`)
}
}
} else {
message.reply('You lack the required permissions to do that. (Required Permissions: ``MANAGE_MESSAGES``)')
}
I have searched and couldn't find much on this, any help is appreciated
I'm not sure if I understand your question correctly. You can check if the member has permission in a certain channel using channel.permissionFor(member).has('PERMISSION_NAME'). I'm not sure if you really wanted the user to have MANAGE_MESSAGES permission, I think SEND_MESSAGES should be enough, so I used that in my code below. I also made it a bit cleaner and added some comments:
const mentionedChannel = message.mentions.channels.first();
// if there is no mentioned channel, channel will be the current one
const channel = mentionedChannel || message.channel;
message.delete();
// returns true if the message author has SEND_MESSAGES permission
// in the channel (the mentioned channel if they mentioned one)
const hasPermissionInChannel = channel
.permissionsFor(message.member)
.has('SEND_MESSAGES', false);
// if the user has no permission, just send an error message and return
// so the rest of the code is ignored
if (!hasPermissionInChannel) {
return message.reply(
`You can't send messages in ${mentionedChannel}. You don't have the required permission: \`SEND_MESSAGES\``,
);
}
const msg = mentionedChannel ? args.slice(1).join(' ') : args.join(' ');
if (!msg) {
// send an error message in the same channel the command was coming
// from and return
return message.reply('Please input a valid sentence/word.');
}
// if the user has permission and has a message to post send it to the
// mentioned or current channel
channel.send(`**Message from ${message.author.tag}:** ${msg}`);
