Adds an extensible API and some basic settings to WordPress to make standard fields on the post edit screen required before a post can be published.
Head to the Writing settings page and scroll to the bottom. There you will find boxes to check to make certain fields required when a user adds or edits a post or page.
The default options are to make the title, content, custom excerpt and category mandatory.
There is an API to add your own required fields too:
/**
* Registers a field as required for a post to be published.
* The default callback checks if the value of the post data or
* post meta field corresponding to the $name is empty or not.
*
* @param string $label Nice name for the required field
* @param string $name The post data array key or custom field key eg: 'post_title', 'my_meta_key'
* @param string $message The error message to display if validation fails
* @param function $validation_cb A callback that returns true if the field value is ok
* @param string|array $post_type The post type or post types to run the validation on
*
* @return void
