Hi.
I've got a table for commands, and fields "id(small int), text(varchar), info(varchar), enable(bool)". Let's say I have this text in field info: "line\nline2\nline3\line4". Unfortunately, there are no new lines in the dialog and it appears exactly like it's in the table, no mater what escape sequence there is. Is there a workaround for this? Because I'd really love to have this feature, since it's very dynamic.
Thanks.

Could you please show the code where you format the message to show to the player (and any variables associated with it)?

pawn Code:

CMD:help(playerid, params[])
{
    mysql_query("SELECT `caption`, `info` FROM `cmd_help` WHERE `enable` = '1'", -1, -1, ssys);
    mysql_store_result(ssys);
    if (mysql_num_rows(ssys)) {
        new data[348], caption[64], help[256];
        mysql_fetch_row_format(data, "|", ssys);
        sscanf(data, "p<|>s[64]s[256]", caption, help);
        ShowPlayerDialog(extraid, DIALOG_CMD_HELP_S, DIALOG_STYLE_MSGBOX, caption, help, "Close", "");
        mysql_free_result(ssys);
    }
    else {
        ShowPlayerDialog(extraid, DIALOG_CMD_HELP_F, DIALOG_STYLE_MSGBOX, "Help", "We're sorry, this command is currently unavailable", "Cancel", "");
        mysql_free_result(ssys);
    }
}

That's it. I'm not formatting it, never thought of doing it.

Does the string that you send to the dialog contain the escape characters in it?

Yes, it does.

Interesting, they must be escaped by one of the plugins. Try this code in order to re-insert them:

pawn Code:

// Not tested (couldn't think of a decent name >.>)
Fix( string[ ] )
{
   for( new i = 0, j = strlen( string ); i < j; i++ )
   {
      if( string[ i ] == '\n' )
      {
         strdel( string, i, i + 1 );
         strins( string, "\n", i );
      }
   }
   return string;
}

It threw a warning,

Code:

warning 224: indeterminate array size in "sizeof" expression (symbol "maxlength")

at the line where strins is, so I've modified it to

pawn Code:

strins( string, "\n", i, strlen(string));

but it didn't work unfortunately .

Interesting, I got it working when I tested with this code:

pawn Code:

new str[ 128 ];
    strins( str, "hello\nthere", 0 );
    Fix( str );
    printf( "STRING: %s", str );

However, but not when using the shortcut

pawn Code:

printf( Fix( "hello\nthere" ) );

So using, in your code, Fix(caption), it should work correctly. Try printing that in the console too, when you put it into the dialog, and see if it shows a line in the console.

Here is the stock function I tested with:

pawn Code:

Fix( string[ ] )
{   
    for( new i = 0, j = strlen( string ); i < j; i++ )   
    {      
        if( string[ i ] == '\n' )      
        {        
            strdel( string, i, i + 1 ); 
            strins( string, "\n", i, 1 ); 
        }   
    }
    return string;
}

I've tested with this version too, but it didn't work. It printed in the console:

Code:

STRING: /givecash <id> <amout>\n/pm <id> <message> ; no new line
