FAQ

Does this work with the Block Editor (Gutenberg)?: Yes. A native sidebar panel appears in the Document Settings for both Classic Editor and Block Editor.
Can I use it on WooCommerce product pages?: Not by default, but you can easily add any custom post type using the smart_rtl_supported_post_types filter (see Description).
Will this slow down my site?: No. The CSS file is only loaded on pages where RTL direction is actually enabled.
Which fonts are available?: Noto Nastaliq Urdu, Scheherazade New, Amiri, Lateef, and a System Serif (no Google Fonts) option.
Does changing direction break my site navigation?: No. Since v1.3.0 the RTL direction is scoped to post content areas only. Your header, navigation menus, and footer are not affected.
What happens when I delete the plugin?: All options and post meta are automatically removed from the database.

I was looking for a simple way to switch my blog posts to right-to-left, and this plugin does exactly that. No extra setup, no confusion — just one click and everything aligns perfectly for RTL languages. It works great for Urdu and Arabic content. The plugin is lightweight and doesn’t slow down the site. Highly recommended for anyone managing RTL content! Thanks to the developer for this helpful tool.

This plugin is a game-changer!With just one click, it perfectly switches the post layout to RTL for languages like Urdu, Arabic, and Pashto. I’ve tested it on both the Gutenberg and Classic editors, and it works flawlessly on both. I especially appreciate how clean and lightweight it is — no unnecessary settings, no complications. Just activate, click, and done. Simple and effective! If you’re running a multilingual or RTL-focused site, this plugin is a must-have. Kudos to the developer!

Changelog

Fixed: WordPress.org submission zip now uses correct folder name ‘smart-rtl-post’ (no version suffix)
Confirmed: WP_UNINSTALL_PLUGIN check present in uninstall.php
Confirmed: Plugin slug, Text Domain, and load_plugin_textdomain are all ‘smart-rtl-post’ — consistent

Confirmed: CSS loads conditionally — only on RTL posts or when [rtl] shortcode detected

1.4.2

Fixed: transition_post_status condition tightened — now only fires when status changes exactly TO publish FROM non-publish (avoids publishdraft, publishtrash edge cases)

1.4.1

Fixed: Default direction now saved to database on first publish (was only shown in UI before)

Fixed: Shortcode CSS now loads even in LTR posts (has_shortcode() detection added)
Fixed: Google Fonts now properly enqueued via wp_enqueue_style (font was named but never loaded)
Fixed: Shortcode [rtl] inline styles replaced with CSS class for better SEO and performance

1.3.1
