Good news!

PHP is a template language!

...from 1995

var personSlug = sanitizeName(person.name);
var string = '
';
string += '
'+person.name+'
';
string += '';
string += '
';
for (var i = 0; i < person.favoriteMovies.length; i++) {
	string += '
' + person.favoriteMovies[i] + '
';
}
string += '
';
						

The Template Language says...

• Take your markup
• Add the variables
• And Handlebars will do the rest

Death Blow
            
Chunnel
            
Cry, Cry Again
	

						

	
{{name}}
	
	

	{{#each favoriteMovies}}
  		
{{this}}
  	{{/each}}

var personSlug = sanitizeName(person.name);
var string = '
';
string += '
'+person.name+'
';
string += '';
string += '
';
for (var i = 0; i < person.favoriteMovies.length; i++) {
	string += '
' + person.favoriteMovies[i] + '
';
}
string += '
';
						

Turns out this is a lot easier

• You can do anything (it just might take a really long time)
• Oh God, Don't Change Anything!
• You run-out of time for the little extras

It's not fun

• Inject
• Meadow
• TwigPress
• Twig WordPress
• Timber

Problem: function stew

• <?php get_the_title(); ?>
• <?php get_the_content(); ?>
• <?php get_permalink(); ?>
• <?php get_post_custom($id, 'my-field', true); ?>

<?php
$thumb_id = get_post_thumbnail_id($post->ID);
$url = wp_get_attachment_url($thumb_id);
?>
<img src="<?php echo $url; ?>" 
alt="Thumbnail for <?php echo $post->post_title; ?>" />
						

Solution: object-based code

Problem: keeping templates neat

Solution: Filters!

Problem: looping

Problem: inclusion

Problem: Linear Page Construction

Solution: Template Inheritance and Extension

In conclusion...
