Template System

Comprehensive guide to the plugin template system - how to customize templates, use hooks, and filters.

Overview

The plugin uses the WordPressTemplates system from wpify/templates for rendering all front-end elements.

Key benefits:

• Templates can be overridden in the theme (child-theme compatible)
• Each template contains hooks for extension
• Data can be filtered before rendering
• WordPress standard API (get_template_part(), load_template())

How the Template System Works

WordPressTemplates Priority

The plugin uses the WordPressTemplates class, which looks for templates in this order:

1. Child theme - {child-theme}/wpify-woo-discount-rules/{template}.php
2. Parent theme - {theme}/wpify-woo-discount-rules/{template}.php
3. Plugin templates - {plugin}/templates/{template}.php

Example:

// The plugin calls:
$this->templates->print('info-block', null, $args);

// WordPress looks in this order:
// 1. wp-content/themes/my-child-theme/wpify-woo-discount-rules/info-block.php
// 2. wp-content/themes/my-theme/wpify-woo-discount-rules/info-block.php
// 3. wp-content/plugins/wpify-woo-discount-rules/templates/info-block.php

---

Frequently Asked Questions

Do I have to override the entire template?

No. You can use hooks to add custom HTML without overriding the template.

Example:

// Instead of overriding info-block.php:
add_action('wpify_woo_discounts_info_block_html_start', function($items, $product) {
    echo '<div class="my-custom-intro">Custom HTML here</div>';
}, 10, 2);

How do I find out what arguments a template has?

Each template has a docblock comment in the file header describing $args.

Example:

/**
 * Info Block Template
 *
 * @var array $args Template arguments
 *   - items   (array)      Array of items with 'rule', 'content', 'pricing'
 *   - product (WC_Product) Product object
 */

Can I use a child theme?

Yes. WordPressTemplates looks for templates first in the child theme, then in the parent theme, then in the plugin.

Structure:

wp-content/themes/my-child-theme/
└── wpify-woo-discount-rules/
    ├── info-block.php
    ├── pricing-table.php
    └── selection-item.php

How do I debug templates?

1. Find out which template is being used:

add_filter('wpify_templates_template_args', function($args, $slug, $name, $filename) {
    error_log("Loading template: $filename");
    error_log("Args: " . print_r($args, true));
    return $args;
}, 10, 4);

2. Output the arguments in the template:

<?php
// In the template
echo '<pre>';
print_r($args);
echo '</pre>';
?>

How do I remove a default hook?

Use remove_action() or remove_filter().

Example:

// Find the hook in the plugin code
// E.g. if the plugin adds a hook in ManualSelectMode::setup_default_template_hooks()

// Remove the hook
remove_action('wpify_woo_discounts_selection_html_item', [
    $manual_select_instance,
    'render_selection_item'
], 10);

// Add your own
add_action('wpify_woo_discounts_selection_html_item', 'my_custom_item_render', 10, 3);
