  • Use the same colors as Reactions: This is the default value and renders the Charts with the same colors you chose in Reactions Settings Page;
  • Use random generated colors: Generates RGB values from reactions labels, so identical labels will have identical colors;
  • Use default rainbow palette: Uses a default palette with 20 different tints, use this if the previous options does not work for you.

Enable user role restrictions [PRO]

Reactions are visible to all site visitor but you may restrict the voting functionality to specific roles.

If you enable restrictions a list of all user roles will be visible to pick one by one the roles enabled to vote.

User identification settings

According to previous settings there will be scenarios in which we need to recognize unlogged user, this is necessary to avoid duplicates and to let users change their vote (see next paragraph).

To recognize unlogged users there are two ways: via IP address, via cookie or both.

Remember that the plugin will not be able to recognize unlogged users without one of these options set to “on” and that you have to mention this on your privacy policy to fulfill privacy law requirements in some countries.

Reactions by content type is another widget for the dashboard and contains real time data about reactions grouped by content type.

Blog reaction summary [PRO]

Reactions by blog is a widget available only on Network dashboard in multisite installation. This widget shows real time statistics for all blogs in the network.


If enabled, the plugin displays reactions buttons under every content, according to saved settings.

The buttons are lazy loaded to avoid slow loading of the site, especially if several buttons should be displayed, this happens typically on comments and archives.

Under the buttons there is a number that represent the total count of every reaction for every specific item.’


On small displays the buttons are hidden ad are shown using the hamburger button navigation. This solution is compatible even with dozens of reactions buttons.

PHP Classes

This plugin is entirely written using object oriented approach with PSR0 convention. All PHP classes are under /classes/, that is PSR0 root for autoload features.

A complete documentation, autogenerated with PHPDoc is included in archive, look for /documentation/ folder.

HTML structure

Frontend markup for this plugin is very simple:

<div class="da-reactions-container-async" data-type="post" data-id="1" data-nonce="df4c50fc98"></div>

This div is the container for the asynchronous loaded buttons, in this way pages are smaller and easier to load and debug.

The lazy loading function inject inside the previous div something like this:

<div class="da-reactions-container ">
    <div class="reactions-toggle"></div>
    <div class="reactions">
        <div class="reaction reaction_1 inactive" data-id="1" data-reaction="1" data-title="Like" data-type="post">
            <img src="/wp-content/plugins/wp-plugin-da-reactions/public/img/1/like-1.png" alt="Like" width="64" height="64">
            <div class="count">2</div>
        <div class="reaction reaction_2 inactive" data-id="1" data-reaction="2" data-title="Love" data-type="post">
            <img src="/wp-content/plugins/wp-plugin-da-reactions/public/img/1/love-2.png" alt="Love" width="64" height="64">
            <div class="count">4</div>
        <div class="reaction reaction_3 inactive" data-id="1" data-reaction="3" data-title="Ah Ah" data-type="post">
            <img src="/wp-content/plugins/wp-plugin-da-reactions/public/img/1/ah-ah-3.svg" alt="Ah Ah" width="64" height="64">
            <div class="count">5</div>
        <div class="reaction reaction_4 inactive" data-id="1" data-reaction="4" data-title="Wow" data-type="post">
            <img src="/wp-content/plugins/wp-plugin-da-reactions/public/img/1/wow-4.svg" alt="Wow" width="64" height="64">
            <div class="count">6</div>
        <div class="reaction reaction_5 inactive" data-id="1" data-reaction="5" data-title="Sad" data-type="post">
            <img src="/wp-content/plugins/wp-plugin-da-reactions/public/img/1/sad-5.svg" alt="Sad" width="64" height="64">
            <div class="count">6</div>
        <div class="reaction reaction_6 inactive" data-id="1" data-reaction="6" data-title="Grrr" data-type="post">
            <img src="/wp-content/plugins/wp-plugin-da-reactions/public/img/1/grrr-6.svg" alt="Grrr" width="64" height="64">
        <div class="count">7</div>

The final markup depends on settings and may vary from site to site.

Custom tables

This plugin works with two custom tables, all database related functions are in /DaReactions/Data.

The table structure is this:

TABLE %prefix%da_r_reactions

Name       |Type      |Length    |Key    |Default           |Extra
ID         |mediumint |9         |PRI    |                  |AUTO_INCREMENT
label      |varchar   |36        |       |"Reaction"        |
file_name  |varchar   |          |       |""                |
created_at |timestamp |          |       |CURRENT_TIMESTAMP |
color      |varchar   |36        |       |"#006699"         |
active     |smallint  |1         |       |1                 |
sort_order |smallint  |3         |       |0                 |


TABLE %prefix%da_r_votes

Name          |Type       |Length |Key    |Default           |Extra
ID            |mediumint  |9      |PRI    |                  |AUTO_INCREMENT
resource_id   |mediumint  |9      |MUL    |NULL              |
resource_type |varchar    |20     |MUL    |NULL              |
emotion_id    |mediumint  |9      |       |                  |
user_id       |varchar    |32     |MUL    |NULL              |
user_token    |varchar    |32     |       |NULL              |
user_ip       |varchar    |16     |       |NULL              |
created_at    |timestamp  |       |       |CURRENT_TIMESTAMP |


The choice to use own tables for this plugin is functional to some features:

  • The queries to pick most voted reactions, most liked posts and things like those are more simple and less time-consuming for the database.
  • In multisite installations every blog has its own tables that are independent from other blogs.
  • When delete all plugin data, on deactivate or uninstall, those table are dropped and there is no garbage left in database.

Add your own SVG

This plugin comes with 250 included SVG monochromatic vector icons, those kind of icons could be colored in real time using color picker; all other image types, such as JPG, GIF or PNG, cannot be colored in real time, and are not vector.

WordPress blocks SVG upload for very important security reasons, so it is impossible to use your own SVGs, but if you are a graphic designer or a developer and you know that your SVG files are 100 percent safe and don’t contain malicious script you may add your own graphic to this plugin.

  • Inside the plugin folder find /admin/icons/svg/ and create your own folder here. This folder name should not start with a underscore _ because files and folder which names begins with this character will be ignored.
  • Inside your own folder copy all your SVG files, just like all other plugin-provided files.
  • Navigate to Reactions » Reactions manager page and click on one of the icons to change graphic.
  • You SVGs will be listed belong the others, and the colorize function should work too.

Translate plugin

This plugin is entirely written in english, but it is one hudred percent compatible with translations using the common WordPress procedure that involves the use of PO and MO files.

The main POT file can be found inside /languages/ along with a complete italian translation that can be used as model.
