These things make up the I in which the script runs. This module takes care of setting up the context for a script: figuring out which configuration file to load, and loading it, opening a connection to the right database, and so forth. Most scripts will only use one context. They can simply have use C4::Context; at the top. Other scripts may need to use several contexts. For instance, if a library has two databases, one for a certain collection, and the other for everything else, it might be necessary for a script to use two different contexts to search both databases. Such scripts should use the C<&set_context> and C<&restore_context> functions, below. By default, C4::Context reads the configuration from F. This may be overridden by setting the C<$KOHA_CONF> environment variable to the pathname of a configuration file to use. =head1 METHODS =over 2 =cut #' # In addition to what is said in the POD above, a Context object is a # reference-to-hash with the following fields: # # config # A reference-to-hash whose keys and values are the # configuration variables and values specified in the config # file (/etc/koha.xml). # dbh # A handle to the appropriate database for this context. # dbh_stack # Used by &set_dbh and &restore_dbh to hold other database # handles for this context. # Zconn # A connection object for the Zebra server use constant CONFIG_FNAME => "/etc/koha.xml"; # Default config file, if none is specified $context = undef; # Initially, no context is set @context_stack = (); # Initially, no saved contexts =item KOHAVERSION returns the kohaversion stored in kohaversion.pl file =cut sub KOHAVERSION { my $cgidir = C4::Context->intranetdir ."/cgi-bin"; unless (opendir(DIR, "$cgidir/cataloguing/value_builder")) { $cgidir = C4::Context->intranetdir; } do $cgidir."/kohaversion.pl" || die "NO $cgidir/kohaversion.pl"; return kohaversion(); } =item read_config_file =over 4 Reads the specified Koha config file. Returns an object containing the configuration variables. The object's structure is a bit complex to the uninitiated ... take a look at the koha.xml file as well as the XML::Simple documentation for details. Or, here are a few examples that may give you what you need: The simple elements nested within the element: my $pass = $koha->{'config'}->{'pass'}; The elements: my $listen = $koha->{'listen'}->{'biblioserver'}->{'content'}; The elements nested within the element: my $ccl2rpn = $koha->{'server'}->{'biblioserver'}->{'cql2rpn'}; Returns undef in case of error. =back =cut sub read_config_file { my $fname = shift; # Config file to read my $retval = {}; # Return value: ref-to-hash holding the configuration my $koha = XMLin($fname, keyattr => ['id'],forcearray => ['listen', 'server', 'serverinfo']); return $koha; } # db_scheme2dbi # Translates the full text name of a database into de appropiate dbi name # sub db_scheme2dbi { my $name = shift; for ($name) { # FIXME - Should have other databases. if (/mysql/i) { return("mysql"); } if (/Postgres|Pg|PostgresSQL/) { return("Pg"); } if (/oracle/i) { return("Oracle"); } } return undef; # Just in case } sub import { my $package = shift; my $conf_fname = shift; # Config file name my $context; # Create a new context from the given config file name, if # any, then set it as the current context. $context = new C4::Context($conf_fname); return undef if !defined($context); $context->set_context; } =item new $context = new C4::Context; $context = new C4::Context("/path/to/koha.xml"); Allocates a new context.
