It uses filters for customization, allowing developers to modify the output.

Here is a list of all possible gwolle_gb_widget shortcode parameters and attributes:

  • book_id – Identifier for the specific guestbook to display entries from.

[gwolle_gb_widget book_id="post_id" /]

Display the latest 7 entries from the guestbook with a maximum of 20 words per entry. Here, the book_id is set to its default value (0), which means that entries from all guestbooks will be shown.

Gwolle Guestbook [gwolle_gb_write] Shortcode

The ‘gwolle_gb_write’ shortcode from the Gwolle Guestbook plugin allows users to add a guestbook entry form to a post or page. It accepts parameters for ‘book_id’, ‘entry_id’, and ‘button’. It dynamically sets the ‘book_id’ to the current post ID if ‘post_id’ is provided. The shortcode also updates the post meta with the ‘book_id’ if it’s the main query on a singular page. The frontend CSS and JavaScript are enqueued for the form, which is appended to the output wrapped in a ‘gwolle-gb’ div.

Shortcode: [gwolle_gb_write]

Parameters

Here is a list of all possible gwolle_gb_write shortcode parameters and attributes:

  • book_id – Identifier of the guestbook, default is 1
  • entry_id – Identifier of the guestbook entry, default is 0
  • button – Determines if button is shown, default is ‘false’

Examples and Usage

Basic example – A simple implementation of the gwolle_gb_write shortcode. The book_id is set to 1 and the button attribute is set to false, meaning the button won’t be displayed.

[gwolle_gb_write book_id=1 button=false /]

Advanced examples

Here, we’re using the shortcode to display a specific guestbook entry by referencing its ID. The book_id is set to 1 and the entry_id is set to the specific ID of the entry we want to display.

[gwolle_gb_write book_id=1 entry_id=15 /]

In this example, we’re using the shortcode to display a guestbook form for a specific post. The book_id is set to ‘post_id’, which means the form will be associated with the ID of the current post.

[gwolle_gb_write book_id=post_id /]

This is an advanced usage of the shortcode where we display a guestbook form for a specific post and also display the button. The book_id is set to ‘post_id’ and the button attribute is set to true.

[gwolle_gb_write book_id=post_id button=true /]

		'button'   => 'false', // default when only the write shortcode is used.
	), $atts );

	if ( $shortcode_atts['book_id'] === 'post_id' ) {
