Perl Template Toolkit (PTT) is a powerful and versatile templating engine that can help you create complex and dynamic web pages. PTT is fast, scalable, and easy to use, making it a great choice for web developers of all levels.

This comprehensive guide will teach you everything you need to know to get started with Perl Template Toolkit, from installation to advanced techniques. By the end of this guide, you'll be able to create complex and dynamic web pages with ease.

Installation

PTT is available for a variety of platforms, including Windows, Mac OS X, and Linux. You can download the latest version of PTT from the official website.

Once you have downloaded PTT, you need to install it. The installation process is simple and straightforward. For detailed instructions, please refer to the official PTT documentation.

Getting Started

Once you have PTT installed, you can start creating templates. A template is a text file that contains HTML code and PTT tags. PTT tags are used to insert dynamic content into your web pages.

To create a new template, simply create a new text file and save it with a .tt extension. For example, you could create a template called "hello.tt" that contains the following code:

You can then use PTT to render your template. To do this, you need to create a Perl script that includes the following code:

use Template::Toolkit;

my $template = Template::Toolkit->new();

my $output = $template->render('hello.tt');

print $output;

This script will render the "hello.tt" template and print the output to the console.

Advanced Techniques

PTT is a powerful templating engine that can be used to create complex and dynamic web pages. In this section, we will cover some of the more advanced techniques that you can use with PTT.

Filters

Filters are used to modify the output of PTT tags. For example, you can use a filter to convert a string to uppercase or lowercase, or to remove HTML tags from a string.

To use a filter, you simply specify the filter name after the PTT tag. For example, the following code will convert the output of the "name" tag to uppercase:

Macros

Macros are used to define reusable blocks of code. This can be useful for creating complex or repetitive content.

To define a macro, you use the `% macro` directive. For example, the following code defines a macro called "header":

% macro header($title) {

}

You can then use the "header" macro in your templates. For example, the following code will print the title of the page in an `h1` tag:

% header("My Page")

Plugins

Plugins are used to extend the functionality of PTT. There are a wide variety of plugins available, including plugins for database access, image manipulation, and caching.

To use a plugin, you need to install it and then load it into your PTT object. For example, the following code loads the "DBI" plugin:

use Template::Toolkit;

my $template = Template::Toolkit->new();

$template->load_plugin('DBI');

You can then use the plugin in your templates. For example, the following code uses the "DBI" plugin to connect to a database and retrieve a list of products:

% DBI::connect('database.sqlite');

% foreach ($product in $dbh->selectall_arrayref('SELECT * FROM products')){{name}%> }

PTT is a powerful and versatile templating engine that can help you create complex and dynamic web pages. This guide has covered the basics of PTT, including installation, getting started, and advanced techniques. By following the tips in this guide, you'll be able to create beautiful and efficient web pages with ease.
