ACF Repeater Email Templates

—

## ✅ Step-by-Step Guide

### 1. **Create the ACF Repeater Field Group**

Go to **ACF → Field Groups** and click **Add New**.

#### Set Location Rules:
– Show this field group if: **Options Page** is equal to **Email Templates** (we’ll create this options page next).

#### Add a **Repeater Field**:
– **Field Label:** Email Templates
– **Field Name:** `email_templates`
– **Field Type:** Repeater

Inside the repeater, add fields like:

| Label | Name | Type |
|——————–|——————–|—————|
| Template Name | `template_name` | Text |
| Email Subject | `email_subject` | Text |
| Email Body | `email_body` | WYSIWYG Editor |

Save the field group.

### 2. **Register the ACF Options Page**

Add this to your `functions.php`:

if (function_exists('acf_add_options_page')) {
    acf_add_options_page([
        'page_title'  => 'Email Templates',
        'menu_title'  => 'Email Templates',
        'menu_slug'   => 'email-templates',
        'capability'  => 'edit_posts',
        'redirect'    => false
    ]);
}

### 3. **Use Email Templates in Code**

To fetch the templates dynamically:

$email_templates = get_field('email_templates', 'option');

if ($email_templates) {
    foreach ($email_templates as $template) {
        echo '<h3>' . esc_html($template['template_name']) . '</h3>';
        echo '<p><strong>Subject:</strong> ' . esc_html($template['email_subject']) . '</p>';
        echo '<div>' . wp_kses_post($template['email_body']) . '</div>';
    }
}

### 4. **Optional: Fetch by Template Name**

Create a helper function to get a template by name:

function get_email_template_by_name($name) {
    $templates = get_field('email_templates', 'option');
    foreach ($templates as $template) {
        if ($template['template_name'] === $name) {
            return $template;
        }
    }
    return null;
}

Usage:

$template = get_email_template_by_name('welcome_email');
if ($template) {
    $subject = $template['email_subject'];
    $body = $template['email_body'];
    // use in wp_mail() or other logic
}

## 🔧 Goal:
Let admins select one of the **email templates (from ACF Repeater on Options Page)** **when editing a product** in WooCommerce.

## ✅ Step-by-Step Integration

### 1. **Add ACF Select Field to Product Page**

Go to **ACF → Field Groups** and click **Add New Field Group**.

#### Settings:
– **Location Rules**:
– Post Type **is equal to** **Product**

#### Add a New Field:
– **Label**: Email Template
– **Name**: `product_email_template`
– **Type**: Select
– **Choices**: Leave **blank** — we’ll populate it dynamically.
– **Return Format**: `Value` or `Label` (recommended: **Value**)

#### Under “Advanced” → set:
– **Allow Null**: Yes (optional)
– **UI**: Yes (makes it a nice dropdown)

Save the field group.

### 2. **Populate Select Field Choices Dynamically (via PHP)**

Add this to your `functions.php` or custom plugin:

add_filter('acf/load_field/name=product_email_template', 'populate_email_template_choices');
function populate_email_template_choices($field) {
    $templates = get_field('email_templates', 'option');

    $choices = [];

    if (!empty($templates)) {
        foreach ($templates as $template) {
            $name = $template['template_name'] ?? '';
            if ($name) {
                $choices[$name] = $name; // key and value both as template name
            }
        }
    }

    $field['choices'] = $choices;
    return $field;
}

> This will dynamically fill the select dropdown on the **WooCommerce product edit page** with email template names from your repeater field.

### 3. **Usage in Code (Front or Backend)**

To fetch the selected email template for a product:

$template_name = get_field('product_email_template', get_the_ID());
$template = get_email_template_by_name($template_name);

if ($template) {
    $subject = $template['email_subject'];
    $body = $template['email_body'];
    // You can use this in emails or custom logic
}

Make sure `get_email_template_by_name()` is defined as shown in the earlier message.

## 🧪 Optional Ideas
– ✅ Trigger this email on product purchase
– ✉️ Send to customer/admin after checkout
– 👀 Add preview feature or show template content in admin

Would you like help with triggering the selected template **after a WooCommerce order is placed** or showing a **preview of the selected template** on the product page?
