NAME

       LedgerSMB::Template::Elements - Template Utility Functions

SYNOPSIS

       Provides utility functions for generating elements for the user interface templates

METHODS

       LedgerSMB::Template::Elements->new()
	   Returns a blessed hashref from this namespace.

       $object->generate_hidden_elements([...]);
	   Builds data structure for hidden form fields.  Values from the $form object are run through $form->quote.

	   Sample data structure added to $form->hidden_elements():

	    $self->{form_elements}{hidden_elements} = [{ type => 'hidden', name => 'foo', value => 'bar'... } ...]

	   A reference to this structure is returned as well.

       $form->generate_radio_elements($radios);
	   Roll out a single radios hash to an array of radio elements, using the values array as index.

	   Sample data structure added to $form->generate_radio_elements($radios):

	   my $radios = {
	       name => 'radio_name',
	       class => 'radio',
	       attributes => { foo => 'bar' },
	       values => [ '1', '2', '3'],
	       labels => [ 'Label one', '', 'Label three'],
	       default_value => '2', };

       $form->generate_checkbox_elements($checkboxes);
	   Roll out a single checkboxes hash to an array of checkbox elements, using the names array as index.	Note that if no 'values' array is
	   passed, value for all checkboxes default to 1.

	   Sample data structure added to $form->generate_checkbox_elements($checkboxes):

	   my $checkboxes = {
	       names => [
		   'checkbox_name1',
		   'checkbox_name2',
		   'checkbox_name3',
	       ],
	       class => 'checkbox',
	       attributes => { foo => 'bar' },
	       values => [ '4', '', '3'],
	       labels => [ 'Label one', '', 'Label three'],
	       default_values => [ 'checkbox_name1'],

	   };

NAME

       LedgerSMB::Template - Template support module for LedgerSMB

SYNOPSIS

       This module renders templates.

METHODS

       new(user => \%myconfig, template => $string, format => $string, [locale => $locale] [language => $string], [include_path => $path],
       [no_auto_output => $bool], [method => $string], [no_escape => $bool], [debug => $bool], [output_file => $string] );
	   This command instantiates a new template:

	   template
	       The template to be processed.  This can either be a reference to the template in string form or the name of the file that is the
	       template to be processed.

	   format
	       The format to be used.  Currently HTML, PS, PDF, TXT and CSV are supported.

	   format_options (optional)
	       A hash of format-specific options.  See the appropriate LSMB::T::foo for details.

	   output_options (optional)
	       A hash of output-specific options.  See the appropriate output method for details.

	   locale (optional)
	       The locale object to use for regular gettext lookups.  Having this option adds the text function to the usable list for the
	       templates.  Has no effect on the gettext function.

	   language (optional)
	       The language for template selection.

	   include_path (optional)
	       Overrides the template directory.  Used with user interface templates.

	   no_auto_output (optional)
	       Disables the automatic output of rendered templates.

	   no_escape (optional)
	       Disables escaping on the template variables.

	   debug (optional)
	       Enables template debugging.

	       With the TT-based renderers, HTML, PS, PDF, TXT, and CSV, the portion of the template to get debugging messages is to be surrounded
	       by <?lsmb DEBUG format 'foo' ?> statements.  Example:

		   <tr><td colspan="<?lsmb columns.size ?>"></td></tr>
		   <tr class="listheading">
		 <?lsmb FOREACH column IN columns ?>
		 <?lsmb DEBUG format '$file line $line : [% $text %]' ?>
		     <th class="listtop"><?lsmb heading.$column ?></th>
		 <?lsmb DEBUG format '' ?>
		 <?lsmb END ?>
		   </tr>

	   method/media (optional)
	       The output method to use, defaults to HTTP.  Media is a synonym for method

	   output_file (optional)
	       The base name of the file for output.

       available_formats()
	   Returns a list of format names, any of the following (in order) as applicable:

	   HTML (always available)
	   TXT (includes CSV, always available))
	   PDF
	   PS
	   XLS
	   ODS
       new_UI(user => \%myconfig, locale => $locale, template => $file, ...)
	   Wrapper around the constructor that sets the path to 'UI', format to 'HTML', and leaves auto-output enabled.

       render($hashref)
	   This command renders the template.  If no_auto_output was not specified during instantiation, this also writes the result to standard
	   output and exits.  Otherwise it returns the name of the output file if a file was created.  When no output file is created, the output
	   is held in $self->{output}.

	   Currently email and server-side printing are not supported.

       output
	   This function outputs the rendered file in an appropriate manner.

       my $bool = _valid_language()
	   This command checks for valid langages.  Returns 1 if the language is valid, 0 if it is not.

       column_heading()
	   Apply locale settings to column headings and add sort urls if necessary.

       escape($string)
	   Escapes a scalar string if the format supports such escaping and returns the sanitized version.
