render_template_part()

An alternative to the native WordPress function get_template_part() that can pass arguments to the local scope.

Installation

• Using composer : composer require freshflesh/wp-render-template-part
• Or manually download and include the src/wp-render-template-part.php file

##Parameters

• $slug: (string) (Required) The slug name for the generic template.
• $name: (string) (Optional) The name of the specialised template. Default value: null
• $args: (array) (Optional) An associative array containing arguments to pass to the template. Default empty array.
• $echo: (boolean) (Optional) Wether to echo or return the rendered template. Default is true.

Usage

To pass arguments to a template partial, use the render_template_part() function.

Simple example

Parent template:

<?php
    $args =  array(
                'title'   => 'Hello there.',
                'content' => 'Lorem ipsum sid amet'
             );
             
    render_template_part( 'block', 'widget', $args );

Child template:

<div class="widget">
    <h2><?php echo $title; // will output 'Hello there.' ?></h2>
    <p><?php echo $content;  // will output 'Lorem ipsum sid amet' ?></p>
</div>

Returning value example

Useful when returning templates through AJAX for instance:

<?php
    // get rendered template
    $html = render_template_part( 'partials/sidebar', 'article', array(
                 'post_id' => $post->ID
            ) );
    // send in json response 
    wp_send_json_success( array( $html );

Features

WP_Query autoloading

Passing a WP_Query instance as a query argument will automatically set it as the current loop.

WP_Post autoloading

Passing a WP_Post instance as a post_object argument will automatically call setup_post_data() so you can start using the_title(), the_content().

Note: query and post_object are therefore reserved argument names

Extendable

2 hooks are provided to extend its behavior:

Action: do_action( "render_template_part_{$slug}", $slug, $name, $args, $echo );

Filter: $args = apply_filters( "render_template_part_{$slug}_args", $args, $slug, $name, $echo );
