Multiple usage - Ahmed21 - 06.08.2016

Hello, I want to make a command with more than one usage (syntax).

Example: if someone types "/h", a usage cmd is sent: /h [BUY/SELL/CONFIG/SELLPLAYER]

If he types "/h buy or sell or config" it shows him a dialog.

But if he types "/h sellplayer" he gets another usage message: /h sellplayer [player id] [Price]

How?

PHP Code:
CMD:h(playerid, params[])
{
    if (!strcmp(params, "buy", true)) ShowPlayerDialog(...);
    else if (!strcmp(params, "sell", true)) ShowPlayerDialog(...);
    else if (!strcmp(params, "config", true)) ShowPlayerDialog(...);
    else if (!strcmp(params, "sellplayer ", true, 10))
    {
        new id, price;
        if (sscanf(params[10], "ri", id, price)) return SendClientMessage(playerid, -1, "/h sellplayer [player id] [Price]");
      
        // code..
    }
    else SendClientMessage(playerid, -1, "/h [BUY/SELL/CONFIG/SELLPLAYER]");
    return 1;
}

PHP Code:
CMD:h(playerid, params[])
{
    new tmp[50]
     if(sscanf(params, "s[5]", tmp)) return SendClientMessage(playerid, -1, "{0008F7}USAGE: {FFFFFF}/H [BUY/SELL]");
    if(strcmp(tmp, "BUY") && strcmp(tmp, "SELL")) return SendClientMessage(playerid, -1, "{0008F7}USAGE: {FFFFFF}/H [BUY/SELL]");
    if(!strcmp(tmp, "BUY"))
    {
        //buy
    }
    if(!strcmp(tmp, "SELL"))
    {
        //sell
    }
    return 1;
}

Thanks both so much but Konstantinos one is more simple for me :P

Re: Multiple usage - Ahmed21 - 06.08.2016

Question: At the "if strcmp params("sellplayer ", true)

I can see a space between the sellplayer and the ", is it needed?

Re: Multiple usage - Konstantinos - 06.08.2016

Yes, it is needed so it can separate the "option" with its parameters.
