## WordPress.org Compliance (Zero Tolerance)

### Security - MANDATORY

#### Output Escaping - ALWAYS Required

```php
// CORRECT - Every output MUST be escaped
echo esc_html($text);              // Plain text
echo esc_attr($value);             // HTML attributes
echo esc_url($url);                // URLs
echo wp_kses_post($html);          // HTML with allowed tags
echo esc_textarea($content);       // Textarea content
echo esc_js($string);              // JavaScript strings

// In HTML context
<h1><?php echo esc_html($title); ?></h1>
<a href="<?php echo esc_url($link); ?>">
<input value="<?php echo esc_attr($value); ?>">

// WRONG - Will cause plugin rejection
echo $text;                        // NEVER - XSS vulnerability
<?php echo $title; ?>              // NEVER - must escape
```

#### Input Sanitization - ALWAYS Required

```php
// GET/POST data - ALWAYS sanitize + unslash
$text = sanitize_text_field(wp_unslash($_POST['field']));
$content = wp_kses_post(wp_unslash($_POST['content']));
$id = absint($_GET['id']);
$slug = sanitize_key($_GET['slug']);
$url = esc_url_raw(wp_unslash($_POST['url']));
$email = sanitize_email(wp_unslash($_POST['email']));

// Query vars (already sanitized by WordPress)
$route = get_query_var('presszone_forum_route');
$page = max(1, (int) get_query_var('presszone_forum_page'));

// WRONG
$text = $_POST['field'];           // NEVER - must sanitize
```

#### Nonce Verification - ALWAYS Required

```php
// In forms
<?php wp_nonce_field('presszone_forum_action', 'presszone_forum_nonce'); ?>

// In handlers
if (!wp_verify_nonce(
    sanitize_text_field(wp_unslash($_POST['presszone_forum_nonce'] ?? '')),
    'presszone_forum_action'
)) {
    wp_die(esc_html__('Security check failed.', 'forum-press-zone'));
}

// URL-based nonces
$url = wp_nonce_url($url, 'presszone_forum_action', 'presszone_forum_nonce');
check_admin_referer('presszone_forum_action', 'presszone_forum_nonce');
```

#### Permission Checks

```php
// Admin check
if (!current_user_can('manage_options')) {
    wp_die(esc_html__('Unauthorized', 'forum-press-zone'));
}

// Moderator check
if (!\\PresszoneForumPlugin\\Roles::canModerate()) {
    wp_die(esc_html__('Unauthorized', 'forum-press-zone'));
}

// Logged-in check
if (!is_user_logged_in()) {
    wp_safe_redirect(wp_login_url(get_permalink()));
    exit;
}

// Owner check (e.g., can edit own post)
$userId = get_current_user_id();
if ((int) $post['user_id'] !== $userId && !current_user_can('edit_others_posts')) {
    wp_die(esc_html__('Unauthorized', 'forum-press-zone'));
}
```

---

## Critical Rules

### Required File Header

```php
<?php
declare(strict_types=1);

namespace PresszoneForumPlugin;

if (!defined('ABSPATH')) {
    exit;
}
```

### Template File Header (No Namespace)

```php
<?php
declare(strict_types=1);

if (!defined('ABSPATH')) {
    exit;
}

/**
 * Template: Template Name
 *
 * Brief description of what this template displays.
 *
 * @package     ForumPressZone
 * @subpackage  Templates/Presszone
 * @version     4.1.9
 *
 * @var object $fpz Template context with helper methods.
 */
```

### Namespace Usage

```php
// CORRECT
namespace PresszoneForumPlugin;
namespace PresszoneForumPlugin\\Api;

// WRONG - NEVER USE
namespace FPZ;  // Deprecated!
```

### Function Prefix - 4+ Characters

```php
// CORRECT - Functions in global scope must use full prefix
function presszone_forum_get_avatar(array $post, int $size = 40): string
function presszone_forum_empty_state(array $args): void
function presszone_forum_render_nested_post(array $post, int $depth): void

// WRONG - Will cause plugin rejection
function fpz_get_avatar()    // TOO SHORT
function pz_helper()         // TOO SHORT
```

### Text Domain - ALWAYS Required

```php
// CORRECT - All user-facing strings
__('Hello', 'forum-press-zone')
esc_html__('Hello', 'forum-press-zone')
esc_attr__('Hello', 'forum-press-zone')
_e('Hello', 'forum-press-zone')
esc_html_e('Hello', 'forum-press-zone')
sprintf(__('Hello %s', 'forum-press-zone'), $name)

// Translators comment for placeholders
/* translators: %s: user display name */
printf(esc_html__('Welcome, %s!', 'forum-press-zone'), esc_html($name));

// WRONG
__('Hello')                    // Missing text domain
__('Hello', 'other-domain')    // Wrong text domain
```

## Router System

### Query Variables

```php
private const QUERY_VARS = [
    'presszone_forum_route',           // Route identifier: index, node, thread, etc.
    'presszone_forum_node_slug',       // Forum/category slug
    'presszone_forum_thread_slug',     // Thread slug
    'presszone_forum_page',            // Pagination page number
    'presszone_forum_action',          // Account action: profile, preferences, etc.
    'presszone_forum_user_id',         // User ID for profiles
    'presszone_forum_user_slug',       // Username slug
    'presszone_forum_post_id',         // Post ID for editing
    'presszone_forum_conversation_id', // Conversation ID
    'presszone_forum_embed_thread_id', // Embedded thread ID
];
```

### URL Patterns

| Pattern | Route | Template |
|---------|-------|----------|
| `/forums/` | `index` | `index.php` |
| `/forums/{slug}/` | `node` | `thread-list.php` |
| `/forums/{node}/{thread}/` | `thread` | `single-thread.php` |
| `/forums/{node}/{thread}/page/{n}/` | `thread` | `single-thread.php` |
| `/forums/{node}/new-thread/` | `new-thread` | `new-thread.php` |
| `/forums/edit-post/{id}/` | `edit-post` | `edit-post.php` |
| `/forums/member/{id}/` | `member` | `member.php` |
| `/forums/account/` | `account` | `account.php` |
| `/forums/account/{action}/` | `account` | `account.php` |
| `/forums/inbox/` | `inbox` | `inbox.php` |
| `/forums/conversation/{id}/` | `conversation` | `conversation.php` |
| `/forums/search/` | `search` | `search.php` |
| `/forums/user/{slug}/posts/` | `user-posts` | `user-posts.php` |

### Accessing Route Data

```php
// Get route type
$route = get_query_var('presszone_forum_route');

// Get slugs
$nodeSlug = get_query_var('presszone_forum_node_slug');
$threadSlug = get_query_var('presszone_forum_thread_slug');

// Get pagination
$page = max(1, (int) get_query_var('presszone_forum_page'));

// Get IDs
$postId = (int) get_query_var('presszone_forum_post_id');
$userId = (int) get_query_var('presszone_forum_user_id');
```

### Router Helper Methods

```php
$router = new \\PresszoneForumPlugin\\Router();

// Get URLs
$baseUrl = $router->getBaseUrl();                           // /forums/
$nodeUrl = $router->getNodeUrl('general-discussion');       // /forums/general-discussion/
$nodeUrl = $router->getNodeUrl('general-discussion', 2);    // /forums/general-discussion/page/2/
$threadUrl = $router->getThreadUrl('general', 'my-thread'); // /forums/general/my-thread/
$profileUrl = $router->getProfileUrl(123);                  // /forums/member/123/
```

---

## Template Loader

### Loading Templates

```php
$templateLoader = new \\PresszoneForumPlugin\\TemplateLoader();

// Load a template
$templateLoader->load('presszone-forum-single-thread');

// Load with arguments
$templateLoader->load('presszone-forum-member', ['user' => $user]);

// Locate a template file (returns path or null)
$path = $templateLoader->locate('presszone-forum-single-thread');
$partPath = $templateLoader->locate('parts/navbar');
```

### Template Context Object ($fpz)

All templates receive a `$fpz` context object with helper methods:

```php
// URL helpers
$forumUrl = $fpz->url('inbox/');                    // /forums/inbox/
$assetUrl = $fpz->asset('js/frontend.js');          // /plugins/forum-press-zone/assets/js/frontend.js
$themeAsset = $fpz->themeAsset('style.css');        // /plugins/forum-press-zone/templates/presszone/assets/style.css

// Settings
$value = $fpz->setting('board_title', 'Forums');    // get_option('presszone_forum_board_title', 'Forums')

// User helpers
$isLoggedIn = $fpz->isLoggedIn();                   // is_user_logged_in()
$user = $fpz->currentUser();                        // wp_get_current_user() or null

// Escaping shortcuts
$safe = $fpz->esc($text);                           // esc_html()
$safe = $fpz->attr($text);                          // esc_attr()
$fpz->e($text);                                     // echo esc_html()

// Theme info
$theme = $fpz->theme();                             // 'presszone'
```

### Template Search Order

1. Child theme: `/forum-press-zone/{theme}/{template}.php`
2. Parent theme: `/forum-press-zone/{theme}/{template}.php`
3. Plugin: `/templates/{theme}/{template}.php`
4. Fallback to default theme if active theme missing template

## Template Helper Functions

### Avatar Helper

```php
// Render user avatar with custom upload support
echo presszone_forum_get_avatar([
    'user_id' => $post['user_id'],
    'avatar_type' => $post['avatar_type'] ?? 'gravatar',
    'avatar_path' => $post['avatar_path'] ?? ''
], 40); // size in pixels

// Supports:
// - 'gravatar' - WordPress/Gravatar avatar
// - 'upload' - Custom uploaded avatar
// - 'default' - Mystery person
```

### Time Diff Helper

```php
// Custom human time diff with singular week handling
echo presszone_human_time_diff(strtotime($post['post_date']), time());
// Output: "5 minutes", "1 week", "3 months"

// In template context
printf(
    esc_html__('%s ago', 'forum-press-zone'),
    presszone_human_time_diff(strtotime($date), time())
);
```

### Empty State Component

```php
presszone_forum_empty_state([
    'title' => __('No threads found', 'forum-press-zone'),
    'message' => __('Be the first to start a conversation!', 'forum-press-zone'),
    'cta_text' => __('Create Thread', 'forum-press-zone'),
    'cta_url' => home_url('/forums/general/new-thread/'),
    'icon' => '🕵️', // optional, default is 🕵️
]);
```

---

## Reusable PHP Components

### Core Classes - USE THESE

| Class | Purpose |
|-------|---------|
| `Cache` | Caching layer (Redis/Memcached/WP transients) |
| `Query` | Database queries with automatic caching |
| `PostCreator` | Thread/post creation, content validation, BBCode parsing |
| `RestBase` | Extend for REST API endpoints |
| `Roles` | Permission and capability checking |
| `Editor` | TinyMCE editor rendering |

### PostCreator Methods - REUSE THESE

| Method | Purpose | Throws |
|--------|---------|--------|
| `checkExternalLinks($content)` | Block external URLs if setting disabled | `InvalidArgumentException` |
| `checkWordFilter($content)` | Block banned words/phrases | `InvalidArgumentException` |
| `sanitizeMessage($content)` | HTML→BBCode conversion, sanitization | - |
| `parseMessage($content)` | BBCode→HTML for display | - |
| `htmlQuotesToBBCode($html)` | Convert nested blockquotes to BBCode (DOMDocument) | - |

```php
// Usage pattern
$creator = new PostCreator();
try {
    $creator->checkExternalLinks($message);
    $creator->checkWordFilter($message);
    $sanitized = $creator->sanitizeMessage($message);
} catch (\\InvalidArgumentException $e) {
    // Handle validation error
}
```

---

### User Role Class Helper

```php
// Get CSS class for role-based styling
$roleClass = \\PresszoneForumPlugin\\UserRanks::getUserRoleClass((int) $post['user_id']);
// Returns: 'presszone-forum-role--admin', 'presszone-forum-role--moderator', etc.

// Usage in template
<a class="<?php echo esc_attr($roleClass); ?>">
    <?php echo esc_html($username); ?>
</a>
```

---

## Breadcrumbs

### Rendering Breadcrumbs

```php
$breadcrumbs = new \\PresszoneForumPlugin\\Breadcrumbs();

// For a node page
$breadcrumbs->render((int) $node['node_id']);

// For a thread page (includes thread title)
$threadUrl = home_url($slugBase . '/' . $nodeSlug . '/' . $threadSlug . '/');
$breadcrumbs->render((int) $thread['node_id'], $thread['title'], $threadUrl);
```

### Output Structure

```html
<nav class="presszone-forum-breadcrumbs" aria-label="Breadcrumb">
    <ol class="presszone-forum-breadcrumbs__list">
        <li class="presszone-forum-breadcrumbs__item">
            <a href="https://example.com/">Home</a>
        </li>
        <li class="presszone-forum-breadcrumbs__item">
            <a href="https://example.com/forums/">Forums</a>
        </li>
        <li class="presszone-forum-breadcrumbs__item presszone-forum-breadcrumbs__item--current">
            <span>General Discussion</span>
        </li>
    </ol>
</nav>
<script type="application/ld+json" class="presszone-forum-schema">
    {"@context":"https://schema.org","@type":"BreadcrumbList",...}
</script>
```

---

## Pagination

### Using Pagination Helper

```php
use PresszoneForumPlugin\\Pagination;

// Get current page
$page = Pagination::getCurrentPage();

// Get items per page
$perPage = Pagination::getPerPage();

// Calculate total pages
$totalPages = Pagination::getPageCount($totalItems);

// Render navigation
echo Pagination::renderNav($page, $totalPages, $baseUrl);

// Render compact page indicators (for thread listings)
echo Pagination::renderCompact($pageCount, $threadUrl);
```

---

## Template Patterns

### Basic Template Structure

```php
<?php
declare(strict_types=1);

if (!defined('ABSPATH')) {
    exit;
}

/**
 * Template: Template Name
 *
 * @package ForumPressZone
 * @var object $fpz Template context.
 */

use PresszoneForumPlugin\\Query;
use PresszoneForumPlugin\\Breadcrumbs;

$query = new Query();
$breadcrumbs = new Breadcrumbs();
$slugBase = get_option('presszone_forum_seo_slug_base', PRESSZONE_FORUM_DEFAULT_SLUG_BASE);

// Get route data
$nodeSlug = get_query_var('presszone_forum_node_slug');

// Fetch data
$node = $query->getNodeBySlug($nodeSlug);

// Handle not found
if (!$node) {
    status_header(404);
    echo '<div class="presszone-forum-error">';
    echo '<span class="presszone-forum-error__icon">💭</span>';
    echo '<p>' . esc_html__('Not found', 'forum-press-zone') . '</p>';
    echo '</div>';
    return;
}
?>
<div class="presszone-forum-container">
    <?php $breadcrumbs->render((int) $node['node_id']); ?>

    <header class="presszone-forum-page-header">
        <h1><?php echo esc_html($node['title']); ?></h1>
    </header>

    <!-- Template content here -->
</div>
```

### Form Pattern

```php
<form action="<?php echo esc_url(admin_url('admin-post.php')); ?>"
      method="post"
      class="presszone-forum-form"
      enctype="multipart/form-data">

    <?php wp_nonce_field('presszone_forum_action', 'presszone_forum_nonce'); ?>
    <input type="hidden" name="action" value="presszone_forum_action">

    <div class="presszone-forum-form-group">
        <label for="title" class="presszone-forum-label">
            <?php esc_html_e('Title', 'forum-press-zone'); ?>
        </label>
        <input type="text"
               id="title"
               name="title"
               class="presszone-forum-input"
               value="<?php echo esc_attr($existing_value ?? ''); ?>"
               required>
    </div>

    <div class="presszone-forum-form-actions">
        <button type="submit" class="presszone-forum-btn presszone-forum-btn--primary">
            <?php esc_html_e('Submit', 'forum-press-zone'); ?>
        </button>
    </div>
</form>
```

### Moderation Actions Pattern

```php
<?php if (current_user_can('manage_options')
       || current_user_can('presszone_forum_moderate_all')
       || current_user_can('presszone_forum_moderate')): ?>
    <div class="presszone-forum-actions-dropdown">
        <button type="button"
                class="presszone-forum-actions-dropdown__trigger"
                title="<?php esc_attr_e('Actions', 'forum-press-zone'); ?>">
            ⋮
        </button>
        <div class="presszone-forum-actions-dropdown__menu">
            <a href="<?php echo esc_url(home_url($slugBase . '/edit-post/' . $post_id . '/')); ?>"
               class="presszone-forum-actions-dropdown__item">
                ✏️ <?php esc_html_e('Edit', 'forum-press-zone'); ?>
            </a>

            <a href="<?php echo esc_url(wp_nonce_url(
                admin_url('admin-post.php?action=presszone_forum_delete&id=' . $post_id),
                'presszone_forum_delete',
                'presszone_forum_nonce'
            )); ?>"
               class="presszone-forum-actions-dropdown__item presszone-forum-actions-dropdown__item--danger"
               onclick="return confirm('<?php esc_attr_e('Are you sure?', 'forum-press-zone'); ?>');">
                🗑️ <?php esc_html_e('Delete', 'forum-press-zone'); ?>
            </a>
        </div>
    </div>
<?php endif; ?>
```

### Recursive Template (Nested Posts)

```php
// In template file - define function with existence check
if (!function_exists('presszone_forum_render_nested_post')) {
    function presszone_forum_render_nested_post(
        array $post,
        int $depth,
        object $fpz,
        Query $query,
        array $thread,
        bool $enableReactions,
        int $userId
    ): void {
        $maxDepth = 6;

        ?>
        <article class="presszone-forum-post"
                 id="post-<?php echo esc_attr((string) $post['post_id']); ?>"
                 data-depth="<?php echo esc_attr((string) $depth); ?>">

            <!-- Post content -->

            <?php
            // Render children recursively
            if (!empty($post['children']) && $depth < $maxDepth):
                foreach ($post['children'] as $child):
                    presszone_forum_render_nested_post(
                        $child,
                        $depth + 1,
                        $fpz,
                        $query,
                        $thread,
                        $enableReactions,

## Common Mistakes to Avoid

| Mistake | Fix |
|---------|-----|
| Missing `defined('ABSPATH')` check | Add `if (!defined('ABSPATH')) exit;` |
| Echo without escaping | Always use `esc_html()`, `esc_attr()`, etc. |
| Missing text domain | Add `'forum-press-zone'` to all strings |
| `$_POST` without sanitization | Use `sanitize_text_field(wp_unslash())` |
| Missing nonce in forms | Add `wp_nonce_field()` |
| Short function prefix | Use `presszone_forum_*` (4+ chars) |
| Using `FPZ\\` namespace | Use `PresszoneForumPlugin` |
| Hardcoded URLs | Use `home_url()`, `admin_url()` |
| Raw database queries | Use `$wpdb->prepare()` |
| Missing permission checks | Check `current_user_can()` before actions |
| Trusting query vars | Validate and sanitize all input |
| Not using `wp_safe_redirect()` | Always use for redirects |
| Missing `exit` after redirect | Always `exit` after `wp_redirect` |
| Using `echo` for JS in templates | Use `wp_json_encode()` + `esc_js()` |
| Inline `onclick` with user data | Escape with `esc_attr()` or use data attributes |

## Schema.org Integration

### Thread Schema

```php
// Generate and set thread schema
$schemaData = \\PresszoneForumPlugin\\Schema::generateForThread(
    $thread,     // Thread data
    $opPost,     // Original post
    $replies,    // Reply array
    $threadUrl   // Full thread URL
);
\\PresszoneForumPlugin\\Schema::set($schemaData);
```

### Forum Schema

```php
$nodeUrl = home_url($slugBase . '/' . $node['slug'] . '/');
$schemaData = \\PresszoneForumPlugin\\Schema::generateForForum($node, $nodeUrl);
\\PresszoneForumPlugin\\Schema::set($schemaData);
```

## CSS Class Conventions

### BEM Naming

```php
// Block
<div class="presszone-forum-card">

// Element
<div class="presszone-forum-card__header">
<div class="presszone-forum-card__body">

// Modifier
<div class="presszone-forum-card presszone-forum-card--featured">
<div class="presszone-forum-btn presszone-forum-btn--primary">
```

### Common Classes

| Class | Purpose |
|-------|---------|
| `presszone-forum-container` | Main content wrapper |
| `presszone-forum-page-header` | Page header with title |
| `presszone-forum-form` | Form wrapper |
| `presszone-forum-form-group` | Form field wrapper |
| `presszone-forum-input` | Text input |
| `presszone-forum-btn` | Button base |
| `presszone-forum-btn--primary` | Primary action button |
| `presszone-forum-btn--secondary` | Secondary action button |
| `presszone-forum-btn--ghost` | Ghost/transparent button |
| `presszone-forum-error` | Error message container |
| `presszone-forum-empty` | Empty state container |

## Quick Reference - Prefixes & Naming

| Context | Prefix/Pattern | Example |
|---------|----------------|---------|
| **PHP Namespace** | `PresszoneForumPlugin` | `namespace PresszoneForumPlugin;` |
| **Global Functions** | `presszone_forum_` | `presszone_forum_get_avatar()` |
| **Query Vars** | `presszone_forum_` | `presszone_forum_route` |
| **Text Domain** | `forum-press-zone` | `__('Text', 'forum-press-zone')` |
| **CSS Classes** | `presszone-forum-` | `.presszone-forum-btn` |
| **Nonce Action** | `presszone_forum_` | `presszone_forum_create_post` |
| **Option Keys** | `presszone_forum_` | `presszone_forum_board_title` |
| **DB Tables** | `wp_presszone_forum_` | `wp_presszone_forum_posts` |

**NEVER USE:** `FPZ`, `pz_`, `fpz_` - Short prefixes cause WordPress.org rejection
