define template in seperate file

Assistant
To define the email template in a separate file for better maintainability and reusability, follow these steps:

### 1. Create a Separate Email Template File
Create a new file, e.g., `email-template.php`, in a suitable directory of your WordPress theme or plugin. For example, in your theme directory:

`wp-content/themes/your-theme/templates/email-template.php`

Add the following content:

<?php
// email-template.php

if (!defined('ABSPATH')) {
    exit; // Prevent direct access
}

?>
<p>Dear <?php echo esc_html($first_name); ?>,</p>

<p>Thanks for applying to list your services with the <strong>National Aphasia Association</strong>! We're reviewing your application and will notify you if it's approved.</p>

<p>Best regards,</p>
<p>The National Aphasia Association</p>

### 2. Update Your Code to Use the Template
Replace your inline template logic with code that loads and uses the external template.

<?php
// Define the subject
$subject = 'Thank You for Applying';

// Define variables
$first_name = sanitize_text_field($_POST['first_name']);
$email = sanitize_email($_POST['email']);

// Start output buffering to capture the template content
ob_start();

// Load the email template
$template_path = get_template_directory() . '/templates/email-template.php';
if (file_exists($template_path)) {
    include $template_path;
} else {
    wp_die('Email template not found.');
}

// Get the template content
$message_content = ob_get_clean();

// Send the email
$headers = array('Content-Type: text/html; charset=UTF-8');
wp_mail($email, $subject, $message_content, $headers);
?>

### 3. Benefits of This Approach
– **Separation of Concerns**: Keeps HTML templates outside of PHP logic for better readability and maintainability.
– **Reusable Templates**: You can reuse the same template for different use cases by passing different variables.
– **Easy Updates**: Updating the template is easier without modifying the main PHP logic.

first echo in the screen
Assistant
If you want to first display the email content on the screen for debugging or testing purposes before sending it, you can output the `$message_content` variable. Here's how you can modify the script to include an echo statement:

<?php
// Define the subject
$subject = 'Thank You for Applying';

// Define variables
$first_name = sanitize_text_field($_POST['first_name']);
$email = sanitize_email($_POST['email']);

// Start output buffering to capture the template content
ob_start();

// Load the email template
$template_path = get_template_directory() . '/templates/email-template.php';
if (file_exists($template_path)) {
    include $template_path;
} else {
    wp_die('Email template not found.');
}

// Get the template content
$message_content = ob_get_clean();

// Echo the message content to the screen for testing
echo $message_content;

// Stop execution after displaying the message if you only want to test
// exit;

// Send the email
$headers = array('Content-Type: text/html; charset=UTF-8');
wp_mail($email, $subject, $message_content, $headers);
?>

### Key Notes:
1. **`echo $message_content;`**:
This will output the email's HTML content directly to the browser.

2. **`exit;` (Optional)**:
Add `exit;` right after the `echo` statement if you only want to see the message on the screen and prevent the email from being sent.

3. **Production Mode**:
Remove the `echo` and `exit;` statements when moving to production to avoid exposing sensitive information.
