nneonneo's Shoutbox

[Sruc]

What happens when they press del or ban?

The log disappear, and when they update the page, appear already, but it doesn't work.

[nneonneo]

Hmm, I think it may be due to character encodings -- post, send or attach the file and I'll see what I can do.

Functions
Command Implementation:
doMsg(string $msg)
Causes the shoutbox to be replaced with $msg until they
use /return (useful for making error messages, etc.)
processCommand(string $text)
Process an admin command. If this function fails to find
a match, it defaults to the user commands.
processUserCommand(string $text)
Process a user command. This function attempts to match
against all known commands. If a valid command match
isn't found, the function will return false and the
shout ("command") will be displayed as a regular shout.
makeShout(string $text)
Produce a shout as if it was from the current user, but
having only a datestamp (and no profile link, etc)
help(string $command - default '')
Allows users to get help on a command. Use <arg> to
denote required arguments and [arg] to denote optional
ones. Note that all <> must be entered as < and >
or they will not work.
Make sure to add an entry in this function for any new
commands.
Shouting:
checkDir(string $logDir)
Check the target directory to make sure it exists.
checkName(string $chatFile)
Check the filename for invalidities.
readChat(string $chatFile,string $logDir)
Dump the contents of the chat file to the client. If the
client is viewing a special message or command, then
readChat simply executes that command or prints the
message back on screen (this command/message is stored
in $_SESSION['readingCmd'])
truncateChat(string $chatFile,string $logDir,integer $max_lines)
Move the first line of a file from the chat file to the
history as long as the chat file exceeds the set
maximum.
writeLine(string $chatFile, string $logDir, string $newText, array $user)
Write a shout to the chat file. $user is an SMF user
session array which determines the username and rank of
the poster.
writeBanList()
Write the current ban list to _banlist.php which is
require'd by this script at the beginning. This allows
for "dynamic" ban lists.
history()
Show the history file in a neat, formatted HTML style.
preg_timeformat(array $matches)
Function used to replace matched <timeval=[UNIX time offset]> with formatted times
as per SMF's timeformat function. Called through preg_replace_callback.
Important Globals
$_SESSION
readingCmd
The command (if it starts with /) or the message to be
read back to the user instead of the normal shoutbox
stuff.
$_GET
n
Used by the history() function to determine the # of
history lines to output.
help
If this is set, the shoutbox will output a full HTML
help message (using help()). Use as a standalone page.
history
If this is set, the shoutbox will output a full HTML
history page (with history()). Use as a standalone page.
banid
For the administrator's ban link: this is passed as the user
ID of the member to be banned.
delete
For deleting shouts; this is a string in the form
datecode | ip (this is the format used in the <em title>
unban
Username/identifier to unban (used by /banlist)
file
File to read for history and delete functions (will be checked)
$_POST
file
Chat file to use. Will be checked for bad characters.
reqtype
What function to carry out (shout, refresh, init)
shout
If reqtype is shout, then this is the shout to be made.
$_SERVER
REMOTE_ADDR
Used for $ip to determine their IP address.
Global Variables
$ban_ips_readpost,$ban_ips_post,$ban_names_readpost,$ban_names_post
Ban variables. _ips or _names is the ban criteria (IP
address or username) while _readpost or _post is the ban
severity (banned from reading+posting or just posting)
$chatFile,$logDir
These determine the location of the chat file.
$chatFile comes from $_POST['file'] while $logDir is hardcoded.
$user
SMF user data array, gleaned from ssi_welcome as a hack.
This determines a lot of things about the user (like the username and status)
$max_lines
Maximum number of lines to have in the shoutbox. Used by truncateChat.
$ip
User's IP address. Gathered from $_SERVER['REMOTE_ADDR'].
$reqType
Request type; see $_POST['reqtype'].
Super-Duper Command Implementation
To add a command, first decide whether this command is *user* or
*admin/mod* level.
The general format of a command is "/command <reqargs>
[optargs]".
Commands are processed in processCommand or processUserCommand.
The former is for admin/mod commands, and the latter is for users.
Processing begins by parsing the args and then running through a
long switch/case block. In this block, you will add your command code.
Your code should begin with a "case '/commandname':"  and end with a
return true; statement.
The two things you will have access to locally are $args and
$cmd. $args is a string containing all the arguments passed, and $cmd is
the exact command used. For example, with the command "/foo bar baz",
$cmd will be "/foo" and $args will be "bar baz". This will be handled by
the "case '/foo':" statement.
Globally, any of the superglobals are available, plus any
globals. All globals are declared already so there is no need to declare
them on your own.
To make a message appear on the client's shoutbox, set the
variable $_SESSION['readingCmd'] to $text (which is the main argument
for the processing function). This causes the exact text of the command
to be reparsed every time the user requests the shoutbox data, and your
information will be returned instead of the regular shouts.
Alternately, the doMsg function allows you to automatically set
a message that will stay up until they use /return.
Remember that whenever your function needs to exit, it must do
so with "return true;" so that the calling function will know not to
"shout" the command.

Thank you

[nneonneo]

Hmm? I meant the Modifications.portuguese.php file, sorry about the confusion.

[adventurer]

@adventurer: Hmm, odd. Have you checked the server error log?

nothing wrong ....
?

[nneonneo]

Hum? Nothing in the server error log, yet moderators can't ban or delete?

Anything in the forum error logs?

[Sruc]

I find this error in forum error logs:

Code Select Expand

8: Undefined index: yshout_loading
Archivo: /homepages/11/d219923774/htdocs/Foro/Themes/Black22/BoardIndex.template.php (main_above sub template - eval?)
Línea: 288

I have searched the line 288:
               return;

Only this.

[nneonneo]

Oh dear, my apologies (to everyone!). I missed a post, and now I've posted wrong advice >.<


Here:

@Sruc: Banning should work, but deletion doesn't work because you've modified this line:

Code Select Expand

if ($user['is_admin'] || $user['is_Moderador Global'])
This should read

Code Select Expand

if ($user['is_admin'] || $user['is_mod'])

As for the yshout_loading error, copy Themes/default/languages/Modifications.english.php to Themes/default/languages/Modifications.<yourlanguage>.php to fix that.

@adventurer: Yet, history will not show? Give me a URL to your forum and I will check it out.

@okidokiss: It's probably due to character encodings (the failure of the special characters to show). Post, PM or attach your Modifications.language.php file, and I'll see what I can do.

[Sruc]

OMFG I'm a newbie >.<'

Excuse me already for the inconveniences and thank you very much.

[trekkie2444]

How do I place the shoutbox directly below my boards and right before the info center?

[exxocet]

Very effective shotbox, Unfortunately yshout.php is restricted by many shared server hosts, they say it uses too much resources on refresh.

[nneonneo]

@trekkie2444: For the default theme, everything you need to do is in Themes/default.
Edit index.template.php and do these three steps:
1) Change

Code Select Expand

',empty($options['collapse_header']) ? 'loadChat();':'','
to

Code Select Expand

loadChat();
2) Remove

Code Select Expand

// YSHOUT HERE
document.getElementById("yshout").style.display = mode ? "none" : "";
if(!mode)
{
loadChat();
}
// YSHOUT END
3) Remove

Code Select Expand

// YSHOUT HERE
echo '
<br /><b>Shout Box</b><br /><br />
<div id="yshout"', empty($options['collapse_header']) ? '>' : ' style="display: none;">',$txt['yshout_loading'],'<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /></div>';
// YSHOUT END
This may appear twice.

The rest depends on where you want it exactly and how it should appear. You have many options:
1) as the first block in the info center
2) as a separate block styled like the info center
3) as a separate block styled like the blocks in the info center (e.g. Users Online block)
Also, it will only appear on the board index, and nowhere else, if this is what you want.

@exxocet: Hmm, I would suppose this is primarily due to my earlier versions being poor at efficiency. The new versions check for new shouts every 20 seconds, which is on par with most autorefresh shoutboxes, but more live because new shouts are near-instantly shown and the 20-second timer reset, instead of waiting for the shoutbox to refresh.

[jossanaijr]

The rest depends on where you want it exactly and how it should appear.

Is it difficult to change to a separete block style before my boards?

[nneonneo]

Nope. Follow the three steps outlined from before (these prevent the box from getting hit by strange collapse bugs).

Now, you have two options, because of where you want it.

a) On every page (this requires an edit to index.template.php)
b) On only the board index (this requires an edit to BoardIndex.template.php).

These two options produce vastly different locations in the code, but should result in approximately the same appearance. Let me know which one you want.

[jossanaijr]

Only the board index.

[nneonneo]

By the way, the code which should be inserted looks like the following:

Code Select Expand

// YSHOUT HERE
echo '
<div class="tborder" style="margin-top: 0;' , $context['browser']['needs_size_fix'] && !$context['browser']['is_ie6'] ? 'width: 100%;' : '', '">
<div class="catbg" style="padding: 5px 5px 5px 10px;">',$txt['yshout_shoutbox'],'
</div>
<table border="0" width="100%" cellspacing="1" cellpadding="5" class="bordercolor" style="margin-top: 1px;">
<tr><td class="windowbg2"><div id="yshout">',$txt['yshout_loading'],'<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /></div></td></tr></table>
</div><br />';
// YSHOUT END

This gets placed wherever you wish the shoutbox to appear. It will wrap the shoutbox with a category-like box, with the words Shout Box over the top.

For "only on the board index, before the first board", place this before

Code Select Expand

/* Each category in categories is made up of:
id, href, link, name, is_collapsed (is it collapsed?), can_collapse (is it okay if it is?),
new (is it new?), collapse_href (href to collapse/expand), collapse_image (up/down image),
and boards. (see below.) */
in BoardIndex.template.php.

For "on every page, after the tabs", put it after

Code Select Expand

// The end of tab section.
echo '
<td class="maintab_' , $last , '">&nbsp;</td>
</tr>
</table>';

For "before the info center", put it before

Code Select Expand

// Here's where the "Info Center" starts... in BoardIndex.template.php.

EDIT: Yeah, I think I've answered your recent post there jossanaijr, let me know if there is a problem.

[jossanaijr]

Worked.  Thanks AGAIN!!!!

[iyeru42]

I tried doing the ...loading shoutbox fix, but it still shows that problem.

[nneonneo]

@jossanaijr: Good to hear.

@iyeru42: Odd. If you give me a URL to your forum, I'll check it out.

[iyeru42]

@jossanaijr: Good to hear.

@iyeru42: Odd. If you give me a URL to your forum, I'll check it out.

I can't seem to find your fix anymore, but here it is for the newest version:

Code Select Expand

var board_url = "'; $boardurlparsed = parse_url($boardurl); echo $boardurlparsed['path'], '";

change to

Code Select Expand

var board_url = "/home2/iyeru42/public_html/board";

Link to the Board

I use the Scribbles theme, and PHP4... because my host's hoster won't upgrade to PHP5.
