  • RSS Feed.
  • BBcode, Emoji and Smiley integration (optional).
  • Easy uninstall routine for complete removal of all database changes.

… and all that integrated in the stylish WordPress look.

Import / Export

You may have another guestbook installed. That's great, because Gwolle Guestbook enables you to import entries easily.
The importer does not delete any of your data, so you can go back to your previous setup without loss of data, if you want to.
Trying Gwolle Guestbook is as easy as 1-2-3.

Import is supported from:

  • DMSGuestbook.
  • WordPress comments from a specific post, page or just all comments.
  • Gwolle Guestbook itself, with Export supported as well (CSV-file).


If you have a problem or a feature request, please post it on the plugin's support forum on I will do my best to respond as soon as possible.

If you send me an email, I will not reply. Please use the support forum.


Translations can be added very easily through GlotPress.
You can start translating strings there for your locale. They need to be validated though, so if there's no validator yet, and you want to apply for being validator (PTE), please post it on the support forum.
I will make a request on make/polyglots to have you added as validator for this plugin/locale.

צילומי מסך

  • Frontend View of the list of guestbook entries. On top the button that will show the form when clicked. Then pagination. Then the list of entries.
  • Widget with different options.

  • Settings Page. This is the first tab where you can select which parts of the form to show and use.
  • Dashboard Widget with new and unchecked entries.



  • Install the plugin through the admin page "Plugins".
  • Alternatively, unpack and upload the contents of the zipfile to your '/wp-content/plugins/' directory.
  • הפעילו את התוסף.
  • Place '[gwolle_gb]' in a page. That's it.

As an alternative for the shortcode, you can use the function show_gwolle_gb(); to show the guestbook in your templates.
It couldn't be easier.

Updating from an old version

With version 1.0 there have been some changes:

  • Gwolle Guestbook uses the Shortcode API now. Make sure your Guestbook page uses '[gwolle_gb]' instead of the old one.
  • The entries that are visible to visitors have changed. Make sure to check if you have everything visible that you want and nothing more.
  • CSS has changed somewhat. If you have custom CSS, you want to check if it still applies.


The plugin itself is released under the GNU General Public License. A copy of this license can be found at the license homepage or
in the gwolle-gb.php file at the top.

Hooks: Actions and Filters

There are many hooks available in this plugin. Documentation is included in the zip file in /docs/actions and /docs/filters. Examples are included. If you have a need for a hook, please request this in the support forum.

Add an entry with PHP code

It is not that hard to add an entry in PHP code.

    $entry = new gwolle_gb_entry();

    // Set the data in the instance, returns true
    $set_data = $entry->set_data( $args );

    // Save entry, returns the id of the entry
    $save = $entry->save();

The Array $args can have the following key/values:

  • id, int with the id, leave empty for a new entry.
  • author_name, string with the name of the autor.
  • author_id, id with the WordPress user ID of the author.
  • author_email, string with the email address of the author.
  • author_origin, string with the city of origin of the author.
  • author_website, string with the website of the author.
  • author_ip, string with the ipaddress of the author.
  • author_host, string with the hostname of that ip.
  • content, string with content of the message.
  • datetime, timestamp of the entry.
  • ischecked, bool if it is checked by a moderator.
  • checkedby, int with the WordPress ID of that moderator.
  • istrash, bool if it is in trash or not.
  • isspam, bool if it is spam or not.
  • admin_reply, string with content of the admin reply message.
  • admin_reply_uid, id with the WordPress user ID of the author of the admin_reply.
  • book_id, int with the Book ID of that entry, default is 1.

Format for importing through CSV-file

The importer expects a certain format of the CSV-file. If you need to import from a custom solution, your CSV needs to conform.
The header needs to look like this:


The next lines are made up of the content.

There are some gotchas:

  • Date needs to be a UNIX timestamp. For manually creating a timestamp, look at the timestamp generator. When using a formatted date, the plugin will try to read it correctly. If it fails it will use today's date.
  • Use commas for field separators. If you use Office software like Excel (which is hell) or LibreOffice Calc, set this correctly.
  • Use double quotes around each field. When no quotes are used the import process can break when having quotes or commas inside the content of the entry.
  • The file should be encoded as UTF-8 without BOM to correctly enter special characters.
  • Make sure you use UNIX line-endings. Any decent text-editor can transform a textdocument (CSV file) to UNIX line-endings.

With version 1.4.1 and older, the field datetime was called date.

You could make a test-entry, export that, and look to see what the importer expects from the CSV.
There is also an example CSV file included in the zipfile of the plugin under '/docs/import_example/'.

If you want to prepare a CSV file from other software, plaese be aware that Microsoft Excel is terrible in dealing with CSV files. You will not manage to create a working CSV file with this. Please use LibreOffice Calc for this.

שאלות נפוצות

How do I get people to post messages in my guestbook?

You could start by writing the first entry yourself, and invite people to leave a message.

Which entries are visible on the Frontend?

Starting with version 1.0, the following entries are listed on the Frontend:

  • מסומן
  • Not marked as Spam
  • Not in the Trash

Before that, in 0.9.7, all the 'checked' entries were visible.

I have a lot of unchecked entries. What do I do?

  • For the entries that you consider spam, but were not automatically marked as spam, you can manually mark them as spam, and they will not be visible anymore.
  • For entries that are not spam, but you still don't want them visible, you can move them to trash.
  • The entries that you want visible, set them to checked.

I want to translate this plugin

Translations can be added very easily through GlotPress.
You can start translating strings there for your locale.
They need to be validated though, so if there's no validator yet, and you want to apply for being validator (PTE), please post it on the support forum.
I will make a request on make/polyglots to have you added as validator for this plugin/locale.

What about Spam?

By default this plugin uses a Honeypot feature and a Timeout feature. If spambots try to post guestbook entries this should work sufficiently.

If you still have problems there are more options:

  • Honeypot feature: Hidden input field that only spambots would fill in.
  • Form Timeout: If the form was sent in too fast after loading the page, the entry will be marked as spam.
  • Nonce: Will verify if you really loaded the page with the form first, before posting an entry. Spambots will just submit the form without having a Nonce.
  • Akismet: Third party spamfilter by Automattic. Works really well, but not everybody likes to use a third party service.
  • Stop Forum Spam: Third party spamfilter. Again, works really well, but not everybody likes to use a third party service.
  • Custom Anti-Spam question: Use a simple quiz question to test if you are human.

I already use WP-SpamShield

WP-SpamShield is a general plugin for anti-spam that supports the general WordPress forms and many plugins.
Activating WP-SpamShield will disable the anti-spam features in Gwolle Guestbook and all anti-spam will be handled by WP-SpamShield.
If you don’t want to use WP-SpamShield’s protection for Gwolle Guestbook, then all you need to do is disable Anti-Spam for Miscellaneous Forms in WP-SpamShield settings.

How can I use Multiple Guestbooks?

You can add a parameter to the shortcode, like:

[gwolle_gb book_id="2"]

This will make that page show all the entries in Book ID 2. In case you read this on, the quotes are supposed to be standard double quotes, no backticks.

If you use the template function, you can use it like this:

show_gwolle_gb( array('book_id'=>2) );

With multiple guestbooks, how do I keep track?

There is no need to use id's that are incrementing.
If you have a lot of guestbooks on lots of pages, you can just use the id of the post as the id of the guestbook. That way you won't have double id's.
You can set the book_id automatically to the post_id with this shortcode:

[gwolle_gb book_id="post_id"]

In case you read this on, the quotes are supposed to be standard double quotes, no backticks.

I use Infinite Scroll with multiple guestbooks

This is not really supported and might result in strange issues.

I only want to show one entry.

You can use a shortcode parameter for showing just one entry:

[gwolle_gb_read entry_id="213"]

In case you read this on, the quotes are supposed to be standard double quotes, no backticks.

I don't see the labels in the form.

This plugin doesn't apply any CSS to the label elements. It is possible that your label elements have a white color on a white background.
You can check this with the Inspector in your browser. If that is the case, you have a theme or plugin that is applying that CSS to your
label elements. Please contact them.

I don't get a notification email.

First check your spambox in your mailaccount.

Second, on the settingspage you can change the From address for the email that is sent.
Sometimes there are problems sending it from the default address, so this is a good thing to change to a real address.

There are also several SMTP plugins, where you can configure a lot of settings for email.

If it still doesn't work, request the maillog at your hosting provider, or ask if they can take a look.

I want to show the form and the list on different pages

There are different shortcodes that you can use.
Instead of the '[gwolle_gb]' shortcode, you can use '[gwolle_gb_write]' for just the form, and '[gwolle_gb_read]' for the list of entries.

There is also a widget that can display the latest entries in a widget area, that has many options.
Alternatively you can use the shortcode '[gwolle_gb_widget]' to display the latest entries in widget layout. Parameters are:

  • book_id, int with an ID.
  • num_entries, int with the shown number of messages.
  • num_words, int with the shown number of words per entry.

I want to show the form immediately, without the button

The shortcodes '[gwolle_gb]' and '[gwolle_gb_write]' have a parameter for the button.
You can use them as '[gwolle_gb button="false"]' or '[gwolle_gb_write button="true"]', to deviate from the default.

Moderation is enabled, but my entry is marked as checked

If a user with capability of 'gwolle_gb_moderate_comments' posts an entry, it will be marked as checked by default, because he can mark it as checked anyway.

Moderation is disabled, but some entries are still unchecked

There is validation of the length of words in the content and author name.
If the words are too long and it looks abusive, it will be marked as unchecked. A moderator will still be needed to manually edit and check these entries.

When opening the RSS Feed, I get a Error 404

You can refresh your rewrite rules, by going to Settings / Permalinks, and save your permalinks again.
This will most likely add the rewrite rule for the RSS Feed.

I use a caching plugin, and my entries are not visible after posting

When you have moderation disabled, Gwolle Guestbook will try to refresh the cache.
If it doesn't on your setup, please let me know which caching plugin you use, and support for it might be added.

You can also refresh or delete your cache manually. Most caching plugins offer support for that.

I use a Multi-Lingual plugin

There are 2 settings that you need to pay attention to. If you saved the settings for the form tab, you should save an
empty header and notice text. It will fill in the default there after saving, but that is okay.
As long as you saved an empty option, or it is still not-saved, then it will show the translated text from your MO file.

Also, you will want to use the book_id parameter of the shortcode for multiple guestbooks.

I use a theme with AJAX

Using a theme with AJAX navigation can give issues. Only on the guestbook page is the JavaScript and CSS loaded.
So you would need to load it on every page to have it available for the guestbook. You can add the following code to functions.php of your theme:

function my_gwolle_gb_register() {
add_action('wp_enqueue_scripts', 'my_gwolle_gb_register', 20);

I don't have any experience myself with AJAX themes. If it doesn't work, please contact the theme author.

My theme has no styling for form fields

You could use this CSS. Please adapt the colors 😉
The CSS can be added in Appearance > Customizer > Custom CSS.

html body div.gwolle-gb input[type="button"],
html body div.gwolle-gb input[type="submit"] {
    color: #fff; /* white */
    background-color: #f00; /* red */
    border: 1px solid #0f0; /* green */

html body div.gwolle-gb form.gwolle-gb-write div.input input[type="text"],
html body div.gwolle-gb form.gwolle-gb-write div.input input[type="email"],
html body div.gwolle-gb form.gwolle-gb-write div.input input[type="url"],
html body div.gwolle-gb form.gwolle-gb-write div.input textarea,
html body div.gwolle-gb form.gwolle-gb-write div.input select {
    border: 1px solid #0f0; /* green */

I use the Autoptimize plugin

The frontend scripts will only be loaded on the Guestbook page, so they won't be added to autoptimize.
You can add 'gwolle_gb_frontend' to both the comma-separated JS and CSS autoptimization exclusion list. That way it will still be loaded right.
On the autoptimize settings page, you might have to click on "show advanced settings"-button top-right first. More info on troubleshooting in AO's FAQ.

What capabilities are needed?

For moderating comments you need the capability 'gwolle_gb_moderate_comments'.

For managing options you need the capability 'manage_options'.

Can I override a template?

You can look at 'frontend/gwolle_gb-entry.php', and copy it to your theme folder. Then it will be loaded by the plugin.
Make sure you keep track of changes in the default templatefile though. It is often better to use filters, that way you are more forward-compatible.

What hooks are available for customization?

There are many hooks available in this plugin. Documentation is included in the zip file in /docs/actions and /docs/filters. Examples are included.
If you have a need for an additional hook, please request this in the support forum.

I want to change the word Guestbook into something else.

First, this plugin is a guestbook. If you want to use it for a different usecase, you will need to do that in code.
Take a look at the previous question about hooks.
You are probably wanting to use these two hooks:

Also, the add-on has options for text changes.

I have a one-page design and want to use links with the right anchor.

It should be possible by using a filter.
Have a look at this example code. Make sure to use the correct anchor tag for your website.

Should I really not use WordPress comments for a guestbook?

Sure you can if you want to. In my personal opinion however it can be a good thing to keep comments and guestbook entries separated.
So if you already have a blog with comments, the guestbook entries might get lost in there, and keeping a separate guestbook can be good.
But if you don't use standard comments, you can just as easily use the comment section for a guestbook.

I love this plugin! You can create other new books by adding an ID. I thought it would be even better if you could use a shortcode in each guestbook to change the email notification destination. That way, for example, on a membership website, users will be able to have a guestbook and receive notifications.

this is the best plugin to place a guestbook on a Wordpress Website, it has everything you need. also the developer gives the best service one can imagine simply TOP

Without the best Guest Book for wordpress. So easy to install and configure and I am over the moon with it and best of all it's FREE! I also purchased The Addon not only to support the developer but the extra features that come with it are well worth the asking price so I highly recommend buying this to support the developer and for the extra features. Thank you so very much for creating this awesome plugin!
