1</a> Introduction</h2>

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.

1.1</a> Overview of application writing</h3>
|
|
|
|
|
|
|
|
|
|
|
|
<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.
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
<h3><a name="tth_sEc1.2">
|
|
|
|
|
|
1.2</a> What does the phpGroupWare API provide?</h3>
|
|
|
|
|
|
|
|
|
|
|
|
<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.
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
These guidelines must be followed for any application that wants considered
|
|
|
|
|
|
for inclusion into phpGroupWare deluxe:
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
|
|
|
|
|
|
<ul><p>
|
|
|
|
|
|
<li> It must run on PHP3 and PHP4.</li>
|
|
|
|
|
|
<p>
|
|
|
|
|
|
<li> SQL statements must be compatible with both MySQL and PostgreSQL.</li>
|
|
|
|
|
|
<p>
|
|
|
|
|
|
<li> It must use our default header.inc.php include.</li>
|
|
|
|
|
|
<p>
|
|
|
|
|
|
<li> It must use our $phpgw_link($url) for all links (this is for session
|
|
|
|
|
|
support).</li>
|
|
|
|
|
|
<p>
|
|
|
|
|
|
<li> It must use ``post'' for forms.</li>
|
|
|
|
|
|
<p>
|
|
|
|
|
|
<li> It must respect phpGW group rights and phpGW user permissions.</li>
|
|
|
|
|
|
<p>
|
|
|
|
|
|
<li> It must use our directory structure, template support and lang (multi-language)
|
|
|
|
|
|
support.</li>
|
|
|
|
|
|
<p>
|
|
|
|
|
|
<li> Where possible it should run on both Unix and NT platforms.</li>
|
|
|
|
|
|
<p>
|
|
|
|
|
|
<li> For applications that do not meet these requirements, they can be
|
|
|
|
|
|
available to users via the phpGroupWare Apps project, or whatever
|
|
|
|
|
|
means the developers decide. If you need help converting your application
|
|
|
|
|
|
to templates and our lang support, we will try to connect you with
|
|
|
|
|
|
someone to help.</li>

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.

|
|
|
|
|
|

3.4</a> Making phpGroupWare aware of your application</h3>
|

|
|
|
|

<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);
|
|
|
|
|
|
|
|
|
|
|
|

3.5</a> Hooking into Administration page</h3>

|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
When a user goes to the Administration page, it starts appname/inc/hook_admin.inc.php
|
|
|
|
|
|
for each application that is enabled, in alphabetical order of application
|
|
|
|
|
|
title. If the file exists, it is include()d in the hopes it will display
|
|
|
|
|
|
a selection of links to configure that application.
|
|
|
|
|
|
|
|
|
|
|

Simple Example:
|
|
|
|
|
|
<pre>
|
|
|
|
|
|
|
|
|
|
|
|
<?php
|
|
|
|
|
|
$img = "/" . $appname . "/images/navbar.gif";
|
|

|

section_end();
|
|
|

|
?>
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|

</pre>Look at headlines/inc/hook_admin.inc.php and admin/inc/hook_admin.inc.php

Things to note:
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
|
|
|
|
|
|
<ul><p>
|
|
|
|
|
|
<li> Links are relative to the admin/index.php file, not your application's
|
|
|
|
|
|
base directory. (so use $appname in your link() calls)</li>
|
|
|
|
|
|
<p>
|
|
|
|
|
|
<li> The file is brought in with include() so be careful to not pollute
|
|
|
|
|
|
the name-space too much</li>
|
|
|
|
|
|
</ul>
|
|
|
|
|
|
The standard $phpgw and $phpgw_info variables are in-scope, as
|
|
|
|
|
|
is $appname which corresponds to the application name in the path.
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
There are 2 functions to coordinate the display of each application's
|
|
|
|
|
|
links, section_start() and section_end()
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
|
|
|
|
|
|
<h4>section_start</h4>
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
section_start($title,$icon_url) starts the section for your application.
|
|
|
|
|
|
$title is passed through lang() for you. $icon_url should be page-relative
|
|
|
|
|
|
to admin/index.php or an absolute URL.
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
|
|
|
|
|
|
<h4>section_end</h4>
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
section_end() closes the section that was started with section_start().

The mechanism to hook into the preferences page is identical to the

|
|
|
|
one used to hook into the administration page, however it looks for
|
|
|
|
|
|
appname/inc/hook_preferences.inc.php instead of appname/inc/hook_admin.inc.php.
|
|
|
|
|

The same functions and variables are defined.

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 accommodate a large number of
|
|
|
|
|
|
applications and functions.

We are completing a program called Transy, which will provide developers/translators

a nice GUI for building and updating translations.

In the mean time you will need to create a SQL script yourself and

name it lang.sql. You can copy the one in doc/lang.sql and use it

as a template.

To do this we have created a multi-dimensional class $phpgw->.
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
This allows for terrific code organization, and help developers easily
|
|
|
|
|
|
identify the file that the function is in. All the files that are
|
|
|
|
|
|
part of this class are in the inc/core directory and are named to
|
|
|
|
|
|
match the sub-class.
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
Example: $phpgw->send->msg() is in the inc/phpgwapi/phpgw_send.inc.php
|
|
|
|
|
|
file.

<p>
|
|
|

$phpgw->link($url)<br />
|
|
|
|
|
|
Add support for session management. ALL links must use this, that
|
|
|
|
|
|
includes href's form actions and header location's.
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
If you are just doing a form action back to the same page, you can
|
|
|
|
|
|
use it without any parameters.

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:

|
|
|
|
|
|
|
|
<pre>
|
|
|
|
|
|
|
|

|
|
<form name=copy method=post action="<?php echo $phpgw->link();?>">
|
|
|
|
|
|
/* If session management is done via passing url parameters */
|
|
|
|
|
|
/* The the result would be */
|
|
|
|
|
|
/* <form name=copy method=post action="somepage.php?sessionid=87687693276?kp3=kjh98u80"> */

<p>
|

|
|
|
|
phpGroupWare attempt to provide developers with as much information
|
|
|
|
|
|
about the user, group, server, and application configuration as possible.
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
To do this we provide a multi-dimensional array called '$phpgw_info[]',
|
|
|
|
|
|
which includes all the information about your environment.
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
Due to the multi-dimensional array approach. getting these values
|
|
|
|
|
|
is easy.
|
|
|
|
|
|
|
|
|

//If username first name is John and last name is Doe, prints: 'Hello John Doe'

phpGroupWare is built using a multi-language support scheme. This
|
|
|
|
|
|
means the pages can be translated to other languages very easily.
|
|
|
|
|
|
Translations of text strings are stored in the phpGroupWare database,
|
|
|
|
|
|
and can be modified by the phpGroupWare administrator.

7.2</a> How to use lang support</h3>
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
The lang() function is your application's interface to phpGroupWare's
|
|
|
|
|
|
internationalization support.
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
While developing your application, just wrap all your text output
|
|
|
|
|
|
with calls to lang(), as in the following code:
|
|
|
|
|
|
<pre>
|
|
|
|
|
|
|
|
|
|
|
|
$x = 42;
|
|
|
|
|
|
echo lang("The counter is %1",$x)."<br>";
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
</pre>This will attempt to translate ``The counter is %1'',
|
|
|
|
|
|
and return a translated version based on the current application and
|
|
|
|
|
|
language in use. Note how the position that $x will end up is controlled
|
|
|
|
|
|
by the format string, <b>not</b> by building up the string in your
|
|
|
|
|
|
code. This allows your application to be translated to languages where
|
|
|
|
|
|
the actual number is not placed at the end of the string.
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
When a translation is not found, the original text will be returned
|
|
|
|
|
|
with a * after the string. This makes it easy to develop your application,
|
|
|
|
|
|
then go back and add missing translations (identified by the *)
|
|
|
|
|
|
later.
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
Without a specific translation in the lang table, the above code will
|
|
|
|
|
|
print:
|
|
|
|
|
|
<pre>
|
|
|
|
|
|
|
|
|
|
|
|
The counter is 42*<br>
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
</pre> If the current user speaks Italian, they string returned
|
|
|
|
|
|
may instead be:
|
|
|
|
|
|
<pre>
|
|
|
|
|
|
|
|
|
|
|
|
il contatore <20> 42<br>
|
|
|
|
|
|
|
|
|

$m6="", $m7="", $m8="", $m9="", $m10="")
|

</dl>
|
|
|
|
|
|
The database is searched for rows with a lang.message_id that matches
|
|
|
|
|
|
$key. If a translation is not found, the original $key is used.
|
|
|
|
|
|
The translation engine then replaces all tokens of the form %N with
|
|
|
|
|
|
the Nth parameter (either $m1[N] or $mN).

|
|

<h4>Adding translation data</h4>
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
An application called <b>Transy</b> is being developed to make this
|
|
|
|
|
|
easier, until then you can create the translation data manually.

|
|
|
|
|

<p>
|
|
|
|

The translation class uses the lang table for all translations. We
|
|
|
|
|
|
are concerned with 4 of the columns to create a translation:

<p>
|
|
|
|
|
|
Currently all applications, and the core phpGroupWare source tree
|
|
|
|
|
|
have a lang.sql file. This is the place to add translation data. Just
|
|
|
|
|
|
add lines of the form:
|
|
|
|
|
|
<pre>
|
|
|
|
|
|
|
|
|
|
|
|
REPLACE INTO lang (message_id, app_name, lang, content)
|
|
|
|
|
|
VALUES( 'account has been deleted','common','en','Account has been deleted');
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
</pre>translating the content to reflect the message_id string
|
|
|
|
|
|
in the lang language. If the string is specific to your application,
|
|
|
|
|
|
put your application name in for app_name otherwise use the name
|
|
|
|
|
|
common. The message_id should be in lower case for a small increase
|
|
|
|
|
|
in speed.

7.3</a> Common return codes</h3>
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
If you browse through the phpGroupWare sources, you may notice a pattern
|
|
|
|
|
|
to the return codes used in the higher-level functions. The codes
|
|
|
|
|
|
used are partially documented in the doc/developers/CODES file.
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
Codes are used as a simple way to communicate common error and progress
|
|
|
|
|
|
conditions back to the user. They are mapped to a text string through
|
|
|
|
|
|
the check_code() function, which passes the strings through lang()
|
|
|
|
|
|
before returning.
|
|
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
|
For example, calling
|
|
|
|
|
|
<pre>
|
|
|
|
|
|
|
|
|
|
|
|
echo check_code(13);
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
</pre>Would print
|
|
|
|
|
|
<pre>
|
|
|
|
|
|
|
|
|
|
|
|
Your message has been sent
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
</pre> translated into the current language.

phpGroupWare is built using a templates based design. This means the
|
|
|
|
|
|
display pages, stored in tpl files, can be translated to other languages,
|
|
|
|
|
|
made to look completely different.
