Question about Fopen/fread - jasperschellekens - 13.12.2017
Hello there,
I am stuck at something.
I managed to save /report succesfully.
But how to make it load?
And more important, how to make it only show latest 10 reports?
code
Код:
new File:log = fopen("Logs/playerreports.txt", io_append);
if(log)
{
getdate(Year, Month, Day);
gettime(hours, minutes, seconds);
format(string,sizeof(string),"[%d/%d/%d][%d:%d:%d]%s reported %s (Reason: %s)'\n\n",Day,Month,Year,hours,minutes,seconds,PlayerName(ID),PlayerName(playerid),reason);
fwrite(log, string);
fclose(log);
}
else
{
print("Failed to open file \"playerreports.txt\".");
}
I know about https://sampwiki.blast.hk/wiki/Fread
But i just don't get how to show them:
Код:
if(handle)
{
// Success
// Read the whole file
while(fread(handle, buf)) print(buf);
// Close the file
fclose(handle);
}

I did this but it does not show any text.
PHP код:
[CODE]CMD:lastreports(playerid,params[])
{
new str[1024],string2[1024],buf[1024];
if(AdminLevel[playerid] >=2)
{
for(new i; i < MAX_REPORTS; ++i)
{
new File:handle = fopen("Logs/playerreports.txt", io_read);
while(fread(handle, str))
if(handle)
{
format(str,sizeof(str),"%s\n\n",buf);
strcat(string2,str);
ShowPlayerDialog(playerid, DIALOG_NONE, DIALOG_STYLE_MSGBOX, "Latest reports", string2, "OK", "");
fclose(handle);
}
else
{
print("Failed to open file \"playerreports.txt\".");
}
}
}
return 1;
}[/CODE]

So i have this now, but it shows like really messed up.
These are the reports in the file:
[14/12/2017][14:14:39]Jasper_Corleone has been reported by Jasper_Corleone. Reason: '1 testreport'
[14/12/2017][14:14:44]Jasper_Corleone has been reported by Jasper_Corleone. Reason: '1 testreport2'
[14/12/2017][14:16:12]Jasper_Corleone has been reported by Jasper_Corleone. Reason: '1 testreport3'
[14/12/2017][14:16:41]Jasper_Corleone has been reported by Jasper_Corleone. Reason: '1 testreport4'
It shows this:
How to fix this?
PHP код:
CMD:lastreports(playerid,params[])
{
new str[1024],string2[1024],buf[128];
if(AdminLevel[playerid] >=2)
{
for(new i; i < MAX_REPORTS; ++i)
{
new File:handle = fopen("Logs/playerreports.txt", io_read);
if(handle)
{
while(fread(handle, buf))
{
format(str, sizeof(str), "%s%s\n", str, buf);
strins(string2, str, strlen(str));
ShowPlayerDialog(playerid, 0, DIALOG_STYLE_MSGBOX, "Last reports", string2, "OK", "");
fclose(handle);
}
}
else
{
print("Failed to open file \"playerreports.txt\".");
}
}
}
return 1;
}

Better to go with SQLite or MySQL because most people use it for saving logs too and its much more easier to work with.

I know it is possible on this way.
Anyone who knows how to fix it?

Not everyone uses mysql, and most certainly, not everyone is gonna use mysql
Re: Question about Fopen/fread - Logic_ - 14.12.2017
Use SQLite then, doesn't require a separate online database, saves database in .db format in scriptfiles folder, gives almost all the features of MySQL. However, Are you using file saving system for your account (register/ login system) script?

You'd have to read the file twice though. Few examples:
pawn Код:
// Reading 10 last reports in ascending order:
new File: fhandle = fopen("Logs/playerreports.txt", io_read), buf[256];
if (fhandle)
{
new lines, at, index, offset;
while (fread(fhandle, buf)) lines++;
at = lines - 10;
lines = 0;
fseek(fhandle);
while ((offset = fread(fhandle, buf)))
{
if (++lines <= at) continue;
if (buf[offset - 2] == '\r') buf[offset - 2] = EOS;
else if (buf[offset - 1] == '\n') buf[offset - 2] = EOS;
printf("%i. \"%s\"", ++index, buf);
}
fclose(fhandle);
}
pawn Код:
// Reading 10 last reports in descending order:
new File: fhandle = fopen("Logs/playerreports.txt", io_read), buf[256];
if (fhandle)
{
new lines, at, index = -1, offset, buf_reports[10][256];
while (fread(fhandle, buf)) lines++;
at = lines - 10;
lines = 0;
fseek(fhandle);
while ((offset = fread(fhandle, buf)))
{
if (++lines <= at) continue;
strcat(buf_reports[++index], buf);
if (buf_reports[index][offset - 2] == '\r') buf_reports[index][offset - 2] = EOS;
else if (buf_reports[index][offset - 1] == '\n') buf_reports[index][offset - 2] = EOS;
}
for (new i = 9; i > -1; i--)
{
printf("%i. \"%s\"", 10 - i, buf_reports[i]);
}
fclose(fhandle);
}
pawn Код:
"[%d/%d/%d][%d:%d:%d]%s reported %s (Reason: %s)\r\n"
