### 🧩 Column Types Explained  
*(In the “Edit Columns” popup for each post type)*

1. **Core Field** – Native WordPress columns (e.g., Title, Date)  
   - Only the label is editable  
   - To customize, uncheck and re-add it as a custom field

2. **Post Field** – Columns from the `wp_posts` table (e.g., post_status, post_author)  
   - Label is editable  
   - Output can be modified via filter hook only

3. **Meta Field** – Auto-detected from the `postmeta` table  
   - Label is editable  
   - Do **not** change the meta key — it must match the database exactly

4. **Custom Field** – Fully flexible  
   - Set your own key and label  
   - Use the hook to render any content  
   - Ideal for developers or integrating third-party fields

5. **Additional Field** –
   - Useful derived values like featured image, word count etc. 
   - Filter hook can be used to modify the content

== Frequently Asked Questions ==

= Does this work with custom post types? =  
Yes, all registered post types will appear. *(Some types like WooCommerce are Pro-only.)*

= Can I show ACF fields in a column? =  
Yes! In Pro plugin the ACF fields can be shown.

= How do I use a custom callback to render column content? =  
Click **“Show Hook”** on the column to see the filter hook. Copy the snippet into your theme's `functions.php` file and return your custom output.  
*(Pro version includes an inline code editor.)*

= What is the filter hook? =  
Developers can extend the `Post Type Column Editor` using WordPress filter hooks. Below is a key filter provided by the plugin:
Use this filter to control what gets displayed in custom columns:

`add_filter( "ptcm_screen_column_value_{$screen_type}_{$post_type}_{$column_key}", function( $value, $post_id , $screen_data) { ... }, 10, 3 );`

This hook allows you to customize the content displayed in your custom admin columns based on the post type and the column key.

🧪 Code Snippet:
```php
<?php
/**
*  `$`screen_type = "post" , `$`post_type = "page",  `$`column_key = "author_name"
*/
add_filter("ptcm_screen_column_value_post_page_author_name", function(`$`value, `$`post_id , `$`screen_data ) {
    return `$`value;
}, 10, 2);`
