## 常見問題集

### Does this plugin work without WooCommerce?

Yes. WooCommerce is completely optional. You can manually add products/services 
to the ezy E Invoice catalogue without WooCommerce installed.

### How are PDFs generated?

PDFs are generated server-side using the FPDF library (bundled). No external service
is required.

### What email service does the plugin use?

It uses WordPress’s built-in `wp_mail()` function, so it works with any SMTP plugin(
e.g. WP Mail SMTP, FluentSMTP).

### Can I customise the invoice PDF design?

The PDF template is in `templates/invoice-pdf-html.php` and the generator class 
is in `includes/class-ezy-pdf.php`. Developers can override these to suit their 
brand.

### Where are invoices stored?

Invoices are stored in custom database tables created on activation. No post types
are used, keeping your WordPress database clean.

### Can I resend an invoice?

Yes. From **ezy E Invoice  Invoices**, click **Resend** on any invoice row to re-
email the PDF to the client.

### Is there a bulk delete option?

Bulk actions are on the roadmap for v2.2. For now, individual delete is available
on each invoice row.

### What happens if I uninstall the plugin?

The `uninstall.php` file removes all plugin options. Database tables are retained
by default to protect your data. You can manually drop them if needed.

## 變更記錄

#### 2.2.4

 * Maintenance: Version bump to 2.2.4.
 * Confirmed: All previous review fixes from v2.2.3 retained — ABSPATH guard, clean
   phpcs:ignore on PDF style block, and smart FPDF loader.

#### 2.2.3

 * Fix: Removed rogue `<style>` tag caused by a broken phpcs:ignore comment embedded
   inside the PHP docblock — the embedded `<?php ?>` tag unintentionally closed 
   PHP mode, making `<style> is required` output as literal HTML. Docblock is now
   plain text.
 * Fix: Replaced the broken inline phpcs:ignore with a clean `<?php // phpcs:ignore...?
   >` line placed immediately before the `<style>` block, correctly suppressing 
   the WPCS enqueue warning for this PDF-only template.
 * Fix: Confirmed `if ( ! defined( 'ABSPATH' ) ) exit;` guard remains at line 2 
   of `templates/invoice-pdf-html.php`.

#### 2.2.2

 * Fix: FPDF smart-load — if another plugin has already loaded FPDF, EZYEIN_FPDF
   now extends it instead of loading the library again, avoiding duplicate code 
   in memory.
 * Fix: FPDF class wrapped with class_exists( ‘EZYEIN_FPDF’ ) guard in both fpdf.
   php and class-ezy-pdf.php to prevent duplicate class definition errors.
 * Fix: Inline tag in invoice-pdf-html.php annotated with phpcs:ignore — template
   is PDF-only (ob_start capture), never served to browser.

#### 2.2.1

 * Fix: Added phpcs:ignore with justification on read-only GET parameter — no nonce
   needed on display-only admin pages.
 * Fix: Invoice view page now accessible via direct URL or bookmark (no nonce expiry
   issue).

#### 2.2.0

 * Security: Replaced deprecated utf8_decode() with mb_convert_encoding() in PDF
   generator.
 * Security: Explicit sanitization of all $_POST fields in client and product save
   handlers.
 * Security: Added wp_unslash() to json_decode() item fields in invoice handler.
 * Security: Nonce verification added to filter/pagination links on invoices list
   page.
 * Improvement: Plugin URI updated to GitHub repository.

#### 2.1.9

 * Fix: Added ABSPATH guard and phpcs:disable to all FPDF font PHP files (third-
   party library).
 * Fix: Replaced readfile() with WP_Filesystem()->get_contents() for PDF delivery.
 * Fix: Removed all error_log() debug calls from PDF class.

#### 2.1.8

 * Fix: PDF is always regenerated fresh on download — no more stale cached layout
   served.

#### 2.1.7

 * Fix: Items table no longer overlaps Bill To section when client has many address
   lines.

#### 2.1.6

 * Fix: FPDF font path now uses DIRECTORY_SEPARATOR — fixes font loading on Windows(
   Laragon/WAMP/XAMPP).

#### 2.1.5

 * Fix: All strings converted via iconv() before passing to FPDF — resolves UTF-
   8 encoding errors.
 * Fix: Logo image load wrapped in try/catch — skipped gracefully on failure.

#### 2.1.4

 * Fix: PDF download now uses secure admin_init handler with nonce — forces browser
   download instead of opening in tab.

#### 2.1.3

 * Fix: Moved phpcs:disable to line 2 in all view/template files for guaranteed 
   PHPCS coverage.

#### 2.1.2

 * Refactor: All class/constant/option/menu prefixes updated to EZYEIN_ for WordPress.
   org compliance.
 * Fix: Replaced fragile ABSPATH path detection with wp_upload_dir().
