## ຄຳອະທິບາຍ
LeTDK helps you manage your site’s TDK (Title, Description, Keywords) from a simple
settings screen—no heavy SEO suite required.
**Features**
* **Homepage TDK** — Custom homepage title, description, keywords, and title separator
* **Category TDK** — SEO fields on category add/edit screens; falls back to the
category name or description when empty
* **Post TDK** — SEO meta box on posts; falls back to the post title or trimmed
content when empty
* **Document title** — Uses `pre_get_document_title` for front-end `` output
* **Meta tags** — Outputs `description` and optional `keywords`
* **Social sharing (Open Graph)** — Optional Open Graph and Twitter Card tags with
a default share image
* **Robots meta** — Optional control for archive indexing and robots directives
* **Master switch** — Disable all front-end SEO output from this plugin when needed
**Highlights**
* Settings live under **Settings LeTDK**
* Dependent fields hide when the master switch is off
* Keyword input converts Chinese commas to English commas
* Homepage title (60) and description (160) length checks support UTF-8 when mbstring
is available
* Uninstall removes plugin options via `uninstall.php`
**Note**
If you already use a full SEO plugin, avoid duplicate meta tags—enable only one
plugin to control titles and meta output.
This plugin is developed by **Lezaiyun Studio** and maintained by LaoJiang.

## ການຕິດຕັ້ງ
#### Automatic installation
1. In your WordPress admin, go to **Plugins Add New**
2. Search for **LeTDK**
3. Click **Install Now**, then **Activate**
#### Manual installation
1. Upload the `letdk` folder to `/wp-content/plugins/`
2. Activate the plugin on the **Plugins** screen
3. Open **Settings LeTDK**
#### Initial setup
1. Enable **TDK optimization**
2. Set homepage title, description, and keywords (use commas between keywords)
3. Optionally enable category TDK, post TDK, social meta tags, and robots meta
4. Click **Save Changes**
## ຄຳຖາມທີ່ພົບເລື້ອຍ
### The page title does not change after I enable LeTDK
Make sure **TDK optimization** is checked. If another SEO plugin also controls titles,
disable one of them to avoid conflicts.
### I do not see SEO fields on categories or posts
Enable **Category TDK** and/or **Post TDK** on the LeTDK settings page. Category
fields appear on **Posts Categories**; post fields appear in the **SEO settings**
meta box when editing a post.
### What keyword format should I use?
Use comma-separated keywords, for example: `WordPress,SEO,plugin`. Chinese commas
entered in the admin are converted to English commas automatically.
### How does the default social share image work?
After you enable **Social sharing tags (OG Meta)**, single posts use the featured
image when available; otherwise the default image from settings is used.
### Does uninstalling remove all data?
Uninstalling deletes the `letdk_options` site option. Custom SEO post meta and term
meta are kept so your content data is not lost.
### What PHP version is required?
PHP 7.4 or newer.
