Wikka Mail


The version 1.5 release is a major feature release for wikka mail. Apart from the increase in functionality (including a category/filter system, an urgent indicator, limits on submitted length in the messages w/ a counter, a "replied to" indicator, etc) there was also a database change (the addition of 5 fields and the removal of one). If you are upgrading from version 1.0 there are detailed instructions at the bottom of the page.

The code below implements a private messaging system in wikka. It allows messages to be sent between users, a contact list to be maintained, user-defined folders for filing the messages, forwarding & replying to messages, etc. The "in-box" and "sent" folder are paginated (because they often have a high number of entries). Most of the functionality of email, with the exception of attachments & multiple recipients, are present. Optional code is provided which can be added to the header.php file providing a visual indicator to show the presence of new, unread messages. Two mysql tables need to be added, one class file (also used in the WikkaBlog2) for pagination placed in the directory "scripts" in the wikka root, and one file (mail.php) placed in the actions directory.

The table prefixes should be set to match the prefix used in your wiki.
CREATE TABLE `wakka_mail` (
  `UserTo` tinytext NOT NULL,
  `repliedto` tinyint(1) DEFAULT '0',
  `folder` tinytext NOT NULL,
  `UserFrom` tinytext NOT NULL,
  `urgent` tinyint(1) DEFAULT NULL,
  `Subject` mediumtext NOT NULL,
  `Message` longtext NOT NULL,
  `fltr1` tinyint(1) DEFAULT '0',
  `fltr2` tinyint(1) DEFAULT '0',
  `fltr3` tinyint(1) DEFAULT '0',
  `status` text NOT NULL,
  `DateSent` datetime DEFAULT NULL,
  `viewrecipient` enum('Y','N') NOT NULL DEFAULT 'Y',
  `mail_id` INT(80) NOT NULL AUTO_INCREMENT,
  PRIMARY KEY  (`mail_id`)
) TYPE=MyISAM;

CREATE TABLE `wakka_mailinfo` (
  `owner` tinytext NOT NULL,

  `info` tinytext NOT NULL,
  `notes` tinytext,
  `id` INT(80) NOT NULL AUTO_INCREMENT,
  PRIMARY KEY  (`id`)
) TYPE=MyISAM;


This code is for mail.php and should be inserted into the actions directory.

To upgrade your mail.php from version 1.0 to 1.5 do the following.....

1) Use the following mysql statements (in your fvaourite mysql administration program, or at the command line if you know how) to update the table structure in your wikki database. Make sure you change "WAKKAPREFIX" to the prefix you use in your wikka.

ALTER TABLE `WAKKAPREFIX_mail`
ADD `repliedto` TINYINT (1) DEFAULT '0' AFTER `Message` ,
ADD `urgent` TINYINT (1) DEFAULT NULL AFTER `repliedto` ,
ADD `fltr1` TINYINT (1) DEFAULT '0' NOT NULL AFTER `urgent` ,
ADD `fltr2` TINYINT (1) DEFAULT '0' NOT NULL AFTER `fltr1` ,
ADD `fltr3` TINYINT (1) DEFAULT '0' NOT NULL AFTER `fltr2` ,
ADD `DateSent` DATETIME NOT NULL AFTER `fltr3`

2) THEN RUN THE PHP SCRIPT mailupdate.php as an ACTION (you can only do this as a designated administrator). Save the php code below as mailupdate.php, insert on a page, and then click on the visible link. This will alter the date code from a text string to a mysql DATETIME string (makes it easier to display date & time).

if ($this->IsAdmin()) {
$link = $this->config["base_url"].$this->MiniHref($method, $tag);
echo "<a href=".$link."&amp;action=update>Update database for mail.php from version 1.0 to version 1.5</a>";
$action=$_GET['action'];
  if($action==update){
  $query="SELECT SentDate,DateSent FROM ".$this->config["table_prefix"]."mail";
  $result=mysql_query($query) or die ("cant do it");
    while ($row=mysql_fetch_array($result)) {
        $newdate=$row[SentDate];
         mysql_query("UPDATE ".$this->config["table_prefix"]."mail SET DateSent=$newdate WHERE SentDate=$newdate");
    }
  if ($_GET['action']) {echo "Database update complete.";}
  }
}


Erase the update file from you actions directory.

3) Then install the new mail.php file. (erase the old one, replace with the new one.) You may or may want to put your wiki into "administrative mode" so that others cannot use it while you do this. (See these notes for upgrading wikka.)

4) Finally, remove the SentDate field from the mysql table WAKKAPREFIX_mail using the following command. (Make sure you change "WAKKAPREFIX" to the prefix you use in your wikka.)

ALTER TABLE `WAKKAPREFIX_mail` DROP `SentDate`

That's it. This upgrade sequence has been tested on two sites and worked without a problem.


Action to display number of new messages waiting


<?php
// This newmail.php (Version 0.1a) is an addon to mail.php. Released under GPL.
// Use: {{newmail}} (no parameters). Needs: Needs: MySQL database tables (2).
$pagename = $this->MiniHref($method, $tag);
$link = $this->config["base_url"].$this->MiniHref($method, $tag);
$username = $this->GetUserName();
$query="SELECT * FROM ".$this->config["table_prefix"]."mail where UserTo='".$username."' and status='unread'";
$result=mysql_query($query) or die ("cant do it");
$num_rows = mysql_num_rows($result);
echo "(".$num_rows.")";
?>


I've then put this action in my wikka.config.php on the logged_in_navigation_links;

:: {{image alt="Private Messages" title="Private Messages" url="images/email.gif" link="PrivateMessages"}} {{newmail}} ::
