This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

Post Author IP

Descripcion

This plugin records the IP address of the original post author when a post first gets created.

The admin listing of posts is amended with a new « Author IP » column that shows the IP address of the author who first saved the post.

The plugin is unable to provide IP address information for posts that were created prior to the use of this plugin.

Hooks

The plugin is further customizable via four filters. Typically, code making use of filters should ideally be put into a mu-plugin or site-specific plugin (which is beyond the scope of this readme to explain).

c2c_show_post_author_ip_column (filter)

The ‘c2c_show_post_author_ip_column’ filter allows you to determine if the post author IP column should appear in the admin post listing table. Your hooking function can be sent 1 argument:

Argument :

  • $show_column (bool) Should the column be shown? Default true.

Example:

/**
 * Don't show the post author IP column except to admins.
 *
 * @param bool $show_column Should the column be shown? Default true.
 * @return bool
 */
function post_author_ip_column_admin_only( $show ) {
    if ( ! current_user_can( 'manage_options' ) ) {
        $show = false;
    }
    return $show;
}
add_filter( 'c2c_show_post_author_ip_column', 'post_author_ip_column_admin_only' );

c2c_get_post_author_ip (filter)

The ‘c2c_get_post_author_ip’ filter allows you to customize the value stored as the post author IP address. Your hooking function can be sent 2 arguments:

Arguments :

  • $ip (string) The post author IP address.
  • $post_id (int) The post ID.

Example:

/**
 * Store all IP addresses from local subnet IP addresses as the same IP address.
 *
 * @param string $ip      The post author IP address.
 * @param int    $post_id The post ID.
 * @return string
 */
function customize_post_author_ip( $ip, $post_id ) {
    if ( 0 === strpos( $ip, '192.168.' ) ) {
        $ip = '192.168.1.1';
    }
    return $ip;
}
add_filter( 'c2c_get_post_author_ip', 'customize_post_author_ip', 10, 2 );

c2c_get_current_user_ip (filter)

The ‘c2c_get_current_user_ip’ filter allows you to customize the current user’s IP address, as used by the plugin. Your hooking function can be sent 1 argument:

Argument :

  • $ip (string) The post author IP address.

Example:

/**
 * Overrides localhost IP address.
 *
 * @param string $ip      The post author IP address.
 * @param int    $post_id The post ID.
 * @return string
 */
function customize_post_author_ip( $ip, $post_id ) {
    if ( 0 === strpos( $ip, '192.168.' ) ) {
        $ip = '192.168.1.1';
    }
    return $ip;
}
add_filter( 'c2c_get_post_author_ip', 'customize_post_author_ip', 10, 2 );

c2c_post_author_ip_allowed (filter)

The ‘c2c_post_author_ip_allowed’ filter allows you to determine on a per-post basis if the post author IP should be stored. Your hooking function can be sent 3 arguments:

Arguments :

  • $allowed (bool) Can post author IP be saved for post? Default true.
  • $post_id (int) The post ID.
  • $ip (string) The post author IP address.

Example:

/**
 * Don't bother storing localhost IP addresses.
 *
 * @param bool   $allowed Can post author IP be saved for post? Default true.
 * @param int    $post_id The post ID.
 * @param string $ip      The post author IP address.
 * @return string
 */
function disable_localhost_post_author_ips( $allowed, $post_id, $ip ) {
    if ( $allowed && 0 === strpos( $ip, '192.168.' ) ) {
        $allowed = false;
    }
    return $allowed;
}
add_filter( 'c2c_post_author_ip_allowed', 'disable_localhost_post_author_ips', 10, 3 );

Screenshots

  • A screenshot of the admin post listing showing the added « Author IP » column. It demonstrates the mix of a post where the post author IP address was recorded, and posts where it wasn’t (due to the plugin not being activated at the time).
  • A screenshot of the Publish metabox for a post showing the post author’s IP address (for versions of WordPress older than 5.0, or later if the new block editor aka Gutenberg is disabled)
  • A screenshot of the block editor sidebar panel for a post showing the post author IP address (WP 5.0 and later)

Installacion

  1. Install via the built-in WordPress plugin installer. Or download and unzip post-author-ip.zip inside the plugins directory for your site (typically wp-content/plugins/)
  2. Activate the plugin through the ‘Plugins’ admin menu in WordPress

FAQ

If a post is originally drafted at one IP address, then later worked on at another IP address, which IP address gets recorded?

The IP address in use at the time that the post is first saved (regardless of whether the post was saved as a draft, immediately published, or some other status) will be recorded.

Are other IP addresses in use during the post’s handling (such as when it is edited, published, etc) also tracked?

No, this plugin only records the IP address in use when the post was first saved.

How do I see (or hide) the « Author IP » column in an admin listing of posts?

In the upper-right of the page is a « Screen Options » link that reveals a panel of options. In the « Columns » section, check (to show) or uncheck (to hide) the « Author IP » option.

Is this plugin compatible with the new block editor (aka Gutenberg)?

Yes. This plugin is compatible with the block editor as well as the classic editor.

Is this plugin GDPR-compliant?

Yes. The IP address stored for authors on the posts they created will be exported on data export requests and deleted for data erasure requests.

Does this plugin include unit tests?

Yes.
