NAME

CGI::okTemplate - Perl extension for easy creating websites with using templates

SYNOPSIS

  use CGI::okTemplate;
  my $tmp = new CGI::okTemplate();
  $tmp->read_template('t/test.tpl');
  print $tmp->parse($data);

or

  use CGI::okTemplate;
  my $tmp = new CGI::okTemplate(File=>'t/test.tpl');
  print $tmp->parse($data);

DESCRIPTION

This is an object oriented template module which parses template files and puts data instead of macros.

Template document can have 3 types of special TAGs:

<% {macroname} %>

        {macroname} - name of variable which will be changed to its value

        if {macroname} undefined in currect block
        it will be changed in outer block.
        if {macroname} undefined in outer block also 
        then this tag will be erased from document 
        if function 'new' not receives parameter 'NoClean' 
        or leave as is if parameter 'NoClean' not used

        you can put spaces between '<%' and '{macroname}' and '%>'

<!--Include {filename}-->

        this tag includes file named {filename} into current
        template file.

        {filename} can be relative (to current template path) 
        or absolute path to the file

<!--{BlockTag} {blockname}-->...<!--/{BlockTag} {blockname}-->

        this tag defines the start and end of the block
        {BlockTag} can be defined in function 'new' by parameter 'BlockTag'
        default {BlockTag} is 'TemplateBlock'

        {blockname} is the name of block.

FUNCTIONS

new

        creates new template object

        use CGI::okTemplate;
        my $tmp = new CGI::okTemplate();

        Possible parameters:
                BlockTag - defines the key work for block tags
                File - path to template file (relative or absolute)
                RootDir - dir where all templates have to be under (default is current dir)
                NoClean - says to not clean tags for undefined variables
                Debug - says to put an info into parsed document

OBJECT FUNCTIONS

read_template($filename)

        defines template file named $filename to he template object
        this function will overwrite the template data defined in 'new' function
        if that function received 'File' parameter

parse($data)

        parses template with data sctructure $data

        $data is the hash reference (see the section DATA STRUCTURE)

DATA STRUCTURE

Data for template is the hash reference.

Hash can have 2 types of value for each key.

        1) string value - it means that this element
has value for {macroname} of current (or inner) block;

        2) array reference - it means that this element
has array of data for block named my key name;

Example :

 Perl Code (example1.pl): 
 -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
 #!/usr/bin/perl
 use CGI::okTemplate;
 my $tmpl = new CGI::Template(  File=>'templates/example1.tpl',
                                BlockTag=>'Block');

 $data = {
        header => 'value for "header" macro',
        footer => 'value for "footer" macro',
        row => [
                {value => 'value1',},
                {value => 'value2',},
                {value => 'value3',},
        ],
 };
 -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

Template File (templates/example1.tpl): -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- <%header%> <!--Block row--><%value%><!--/Block row--> <%footer%> -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

The result have to be: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- value for "header" macro value1 value2 value3 value for "footer" macro -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

As we can see row has reference to the array of simple data structures for block named 'row' This array has 3 elemens. So this block will be parsed 3 times.

See example folder for examples.

EXPORT

None by default.
