The file project.xml contains some informations on the application. Some of these are important because they are used by the installer. Here is an example:

A module.xml file must be present in each directory of modules. It describes some general information, and dependencies with other modules.

<module xmlns="http://jelix.org/ns/module/1.0">
    <info id="jelix_tests@testapp.jelix.org" name="jelix_tests">
        <version>1.0</version>

        <module name="jauthdb" />

Jelix framework configuration is stored in an ini-like file. It is a file structured by sections ([section name]). Each section is a collection of parameter-name=value pairs. There is a generic section, un-named, usually at the start of such file.

Configuration files are stored in var/config.

As said before, each entry point may have its specific config file. Although in practice, many parameters can be shared between them. To prevent wasteful repeats defines a common config file : defaultconfig.ini.php. Jelix automatically read its entries in addition to each config file related to an entry point. No need to tell jelix about it in an entry point.

Then, should lay in an entry point related config file, only specific parameters or overloaded parameters already defined in defaultconfig.ini.php.

A glimpse at defaultconfig.ini.php (abstract):

locale = "fr_FR"
charset = "ISO-8859-1"
timeZone = "Europe/Paris"
theme = default

pluginsPath = lib:jelix-plugins/,app:plugins/
modulesPath = lib:jelix-modules/,app:modules/

[modules]
mymodule=2
jauth=2

[coordplugins]
;nom = nom_fichier_ini

[responses]
...

Example: a classic request with index.php as entry point should define var/config/index/config.ini.php file. Storing under an index sub-directory serves only a better organization (As each entry point may have its config file, var/config would quickly become a mess).

A specific config should only define or redefine a small amount of properties:

startModule = "testapp"
startAction = "main:index"

[coordplugins]
autolocale = index/autolocale.ini.php

[responses]
html=myHtmlResponse

take xmlrpc.php entry point, its config file could be :

  startModule = "testapp"
  startAction = "xmlrpc:index"

And so on for others entry points.

You have to know that a second defaultconfig.ini.php exists into the lib/jelix/core/ directory. It contains all possible parameters and some comments. Jelix reads it first, then it read the defaultconfig.ini.php of your application, and then it reads the configuration file of the entry point. Values of a configuration file override values of the previous configuration file.

This file contains all connections parameters of some Jelix Components: SQL and NoSQL databases, SOAP web services, cache etc. In Jelix 1.2 and lower, these parameters were stored in several files (dbProfils.ini.php, cache.ini.php...). Since Jelix 1.3, all is stored in an unique file.

This is an ini file. Each section correspond to a profile. A profile is a set of parameters of a single connection. Sections names are composed of two names, separated by a ":":

• first name is the name of the connection type, (often corresponding to the composant name)
• second name is a name of your choice. However two names have a special meaning: "default" indicates the default profile to use if the profile name is not given to the component. And "common", described below.

The content of the section content connection parameters.

Here is an example for a jDb connection (jDb allow to access to a SQL database):

[jdb:default]
driver=mysqli
host=localhost
login= mylogin
password=mypassword

Profile Alias ¶

[jdb]
jacl2_profile = default

[jdb:default]
driver=mysqli
host=localhost
login= mylogin
password=mypassword

Common parameters ¶

[jdb:__common__]
host=my.server.example.com
persistant=on

You can use a profile which is not declared in profiles.ini.php file. Then you can use a connection whose informations is known only during the execution.

A virtual profile must be created before using your component. Use createVirtualProfile method of the object jProfiles and pass it, the type name of connection, a name and an array of parameters.

Example

   $params = array(
       'driver'=>'mysqli',
       'host'=>'localhost',
       'database'=>'jelix',
       'user'=>'toto',
       'password'=>'blabla',
       'persistent'=>false,
       'force_encoding'=>true
   );
   jProfiles::createVirtualProfile('jdb', 'my_profil', $params);

   $cnx = jDb::getConnection('my_profil');
   // and play with your database

Of course, all parameters defined in a __common__ profile apply on virtual profiles.
