<EM> This document explains phpGroupWare's infastructure and API, along with what is required to integrate applications into it.</EM>
<HR>
<H2><A NAME="s1">1. Introduction</A></H2>
<P>phpGroupWare is a web based groupware application framework (API), for writing applications. Integrated applications such as
email, calendar, todo list, address book, and file manager are included.
<H2>1.1 Overview of application writing</H2>
<P>We have attempted to make writing application for phpGroupWare as painless as possible.
We hope any pain and suffering is cause by making your application work, but not dealing with phpGroupWare itself.
<H2>1.2 What does the phpGroupWare API provide?</H2>
<P>The phpGroupWare API handles session management, user/group management, has support for multiple databases, using the PHPLIB database abstraction method, we support templates using the PHPLIB Templates class, a file system interface, and even a network i/o interface.<BR>
On top of these standard functions, phpgroupWare provides several functions to give you the information you need about the users environment, and to properly plug into phpgroupWare.
<H2><A NAME="s2">2. Guidelines</A></H2>
<H2>2.1 Requirements</H2>
<P>These guidelines must be followed for any application that wants considered for inclusion into phpGroupWare deluxe.
<P>It must run on PHP3 and PHP4. <BR>
SQL statements must be compatible with both MySQL and PostgreSQL.<BR>
It must use our default header.inc.php include.<BR>
It must use our <CODE>$phpgw_link($url)</CODE> for all links (this is for session support).<BR>
It must respect phpGW group rights and phpGW user permissions.<BR>
It must use our directory structure, template support and lang (multi-language) support.<BR>
Where possible it should run on both Unix and NT platforms.
<P>For applications that do not meet these requirements, they can be avalible to users via the phpGroupWare Apps project, or whatever means the developers decide.<BR>
If you need help converting your application to templates and our lang support, we will try to connect you with someone to help.
<H2>2.2 Writing/porting your application</H2>
<H3>Include files</H3>
<P>Each PHP page you write will need to include the header.inc.php along with a few variables.<BR>
This is done by putting this at the top of each PHP page.
<HR>
<PRE>
&lt;?php
$phpgw_flags["currentapp"] = "appname";
include("../header.inc.php");
?>
</PRE>
<HR>
Of course change application name to fit.<BR>
This include will provide the following things:
<UL>
<LI> The phpgwAPI - The phpGroupWare API will be loaded.</LI>
<LI> The phpGW navbar will be loaded (by default, but can be disabled until a later point.</LI>
<LI> appname/inc/functions.inc.php - This file is loaded just after the phpgwAPI and before any html code is generated. This file should include all your application specific functions.. You are welcome to include any additional files you need from within this file.</LI>
<LI> appname/inc/header.inc.php - This file is loaded just after the system header/navbar, and allows developers to use it for whatever they need to load.</LI>
<LI> appname/inc/footer.inc.php - This file is loaded just before the system footer, allowing developers to close connections and whetever else they need.</LI>
<LI> The phpGW footer will be loaded, which closes several connections.</LI>
</UL>
<P>
<H2><A NAME="s3">3. Installing your application</A></H2>
<H2>3.1 Overview</H2>
<P>It is fairly simple to add and delete applications to/from phpGroupWare.
<H2>3.2 Automatic features</H2>
<P>To make things easy for developers we go ahead and load the following files.
<UL>
<LI> appname/inc/functions.inc.php - This file should include all your application specific functions.</LI>
<LI> appname/inc/header.inc.php - This file is loaded just after the system header/navbar, and allows developers to use it for whatever they need to load.</LI>
<LI> appname/inc/footer.inc.php - This file is loaded just before the system footer, allowing developers to close connections and whetever else they need.</LI>
</UL>
<H2>3.3 Adding files, directories and icons.</H2>
<P>You will need to create the following directories for your code <BR>
(replace 'appname' with your application name)<BR>
<PRE>
`-- appname
`-- images
| `-- navbar.gif
`-- inc
| |-- functions.inc.php
| |-- header.inc.php
| `-- footer.inc.php
`-- templates
`-- default
</PRE>
<H2>3.4 Making phpGroupWare aware of your application</H2>
<P>To make the application aware of your application, add your application details to the applications table. This can be done via the GUI administration screen, or via a sql script.
<PRE>
insert into applications (app_name, app_title, app_enabled) values ('appname', 'The App name', 1);
</PRE>
<H2><A NAME="s4">4. Infastructure</A></H2>
<H2>4.1 Overview</H2>
<P>phpGroupWare attempts to provide developers with a sound directory structure to work from.<BR>
The directory layout may seem complex at first, but after some use, you will see that it is designed to accommidate a large number of applications and functions.
<H2>4.2 Directory tree</H2>

<H2>4.3 Translations</H2>
<P>The translations are now being done thru the database, and will be configurable to use other mechanism.<BR>
I will document all the new abilities during my next update of this document.
<H2><A NAME="s5">5. The API</A></H2>
<H2>5.1 Introduction</H2>
<P>phpGroupWare attempts to provide developers with a useful API to handle common tasks.<BR>
To do this we have created a multi-dimensional class $phpgw->.<BR>
This allows for terrific code organization, and help developers easily identify the file that the function is in.
All the files that are patr of this class are in the inc/core directory and are named to match the sub-class.<BR>
Example:
<CODE>$phpgw->send->msg()</CODE> is in the <CODE>inc/phpgwapi/phpgw_send.inc.php</CODE> file.
<H2>5.2 Basic functions</H2>
<H3>$phpgw->link</H3>
<P><CODE>$phpgw->link($url)</CODE><BR>
Add support for session management. ALL links must use this, that includes href's form actions and header location's.<BR>
If you are just doing a form action back to the same page, you can use it without any paramaters.<BR>
This function is right at the core of the class because it is used so often, we wanted to save developers a few keystrokes.
Example:
<HR>
<PRE>
&lt;form name=copy method=post action="&lt;?php echo $phpgw->link();?>">
/* If session management is done via passing url paramaters */
/* The the result would be */
/* &lt;form name=copy method=post action="somepage.php?sessionid=87687693276?kp3=kjh98u80"> */
</PRE>
<HR>
<H2>5.3 Application Functions</H2>
<P>
<H3>$phpgw->common->appsession</H3>
<P><CODE>$phpgw->common->appsession($data)</CODE><BR>
Store important information session information that your application needs.<BR>
<CODE>$phpgw->appsession</CODE> will return the value of your session data is you leave the paramater enmpty [i.e. <CODE>$phpgw->appsession("")</CODE>], otherwise it will store whatever data you send to it.<BR>
You can also store a comma delimited string and use <CODE>explode()</CODE> to turn it back into an array when you recieve the value back.<BR>
Example:
<HR>
<PRE>
$phpgw->common->appsession("/path/to/something");
echo "Dir: " . $phpgw->common->appsession();
</PRE>
<HR>
<H2>5.4 File functions</H2>
<H3>$phpgw->vfs->read_file</H3>
<P><CODE>$phpgw->vfs->read_file($file)</CODE><BR>
Returns the data from $file.<BR>
You must send the complete path to the file.<BR>
Example:
<HR>
<PRE>
$data = $phpgw->vfs->read_file("/some/dir/to/file.txt");

<H2>6.1 Introduction</H2>
<P>phpGroupWare attempt to provide developers with as much information about the user, group, server, and application configuration as possible.<BR>
To do this we provide a multi-dimensional array called '$phpgw_info[]', which includes all the information about your environment.<BR>
Due to the multi-dimensional array approach. getting these values is easy. <BR>
Here are some examples:
<HR>
<PRE>
&lt;?php

<H2><A NAME="s7">7. Using Language Support</A></H2>
<H2>7.1 Overview</H2>
<P>phpGroupWare is built using a multi-language support scheme. This means the pages can be translated to other languages
very easily. It is done thru a series of lang files, which can be translated and selected by the user.
<H2>7.2 How to use lang support</H2>
<P>Some instructions on using the lang files.<BR>
Under inc/lang there needs to be a sub-directory for each langague. Inside the
directory there are a number of files for each application. There is one common file
which contains a list of words that all applications use. ie, add, delete, edit, etc...<BR>
Words that are specific to a application should be stored with that applications include file.

The list of words in the left column should always be written in english. The
second column is used to return those words in that includes language. <CODE>$m1, $m2,
$m3, and $m4</CODE> are used to pass extra data to be place in the middle of a sentence.<BR>
For example:
<PRE>
You have 29 new messages!
</PRE>
The default should return a bold faced * and the word that wasn't found. This allows users to notice that something is missing in the files and make changes if
necessary.
