Helper Functions

Array argument validation is_arg() and get_arg()

This is great to help you pass functions between template parts.

e.g. get_template_part('template-parts/component','animals', $animals_args);

Template Part - section-zoo.php

/*------------------------------------*\
	# EXAMPLE ARRAY
\*------------------------------------*/

$animal_args = array(
	'animals' => array('dog', 'deer', 'cat'),
	'title' => get_field('title'),
	'sub_title' => 'Animals'
);

get_template_part('template-parts/component','animals', $animals_args);

Template Part - component-animals.php

/*------------------------------------*\
	# EXAMPLE OUTPUT
\*------------------------------------*/

$is_title     = is_arg('title', $args); // This will return false because get_field('title') doesn't exist.
$is_nothing   = is_arg('something', $args); // This will return false.
$is_animals   = is_arg('animals', $args); // This will return truthy as an array.

$sub_title = get_arg('sub_title', $args); // This will return 'Animals'.

$animals = get_arg('animals', $args);

if($animals && is_array($animals) ) {
	foreach( $animals as $animal ) {
		echo $animal;
	}
}

Attribute output from associative array get_attributes()

This is used in component_button() to add more attributes that don't have specific arguments.

$attributes = array(
	'data-url' => 'http://lateralaspect.com.au',
	'data-id' => 'latasp',
);

get_attributes( $attributes );

Returns: data-url="http://lateralaspect.com.au" data-id="latasp"
