Database Management tool – Adminer


The best database management tool for the best CMS.

This plugin uses the tool Adminer 4.8.1 in order to give database access to administrators directly from the Dashboard.
As simple as the previous sentence!

Compatible also with WordPress Multisite installations

  • Gift Wrapping for WooCommerce: This plugin allows customers to select a gift wrapper for their orders, via a checkbox in the checkout page.


  • The WP Adminer opened from Admin Bar


  1. Download the plugin from Official WP Plugin Repository
  2. Upload Plugin from your WP Dashboard ( Plugins > Add New > Upload Plugin ) the file.
  3. Activate the plugin through the ‘Plugins’ menu in WordPress Dashboard


Is it safe?

Yes, because only administrators have access to WP Adminer. If a guest try to access the WP Adminer URL, a 404 page will be shown up.

Who have access in WP Adminer?


  • In the case of single site WordPress installations, only Administrators have access in WP Adminer, because by default only administrator have the manage_options capability.
  • In the case of WordPress Multisite installations, only Super Admins have access in WP Adminer, because by default only Super Admins have the manage_network_options capability.

How to allow other capabilities or roles to have access to WP Adminer?

Just use the filter pexlechris_adminer_access_capabilities and return the array of desired capabilities that you want to have access to WP Adminer.
For roles, just use the corresponding capabilities, while checking against particular roles in place of a capability is supported in part, this practice is discouraged as it may produce unreliable results.

How can I access other databases in the same server and same database user?

By default, you haven’t access to any database other than the site’s database. In order to enable access, you need to add the following line code define('PEXLECHRIS_ADMINER_HAVE_ACCESS_ONLY_IN_WP_DB', false); in the wp-config.php file.

How to add my own JS and/or CSS in adminer head?

You need to use action pexlechris_adminer_head as follows:

  add_action('pexlechris_adminer_head', function(){
  <script nonce="<?php echo esc_attr( get_nonce() )?>"> // get_nonce is an adminer function
     // Place your JS code here
     /* Place your CSS code here */

How can I add other Adminer plugins or Adminer extensions?

In Adminer’s website there is documentation about Adminer plugins and Adminer extensions.
In order to define function adminer_object() before this plugin define it, you need to define it inside the hook pexlechris_adminer_before_adminer_loads.
More in the phpDoc below:

  * adminer_object can be overridden, in WP action pexlechris_adminer_before_adminer_loads.
  * If a developer want to make his/her own changes (adding plugins, extensions or customizations),
  * it is strongly recommended to include_once the class Pexlechris_Adminer and extend it and
  * make adminer_object function return his/her new class.
  * It is strongly recommended, because Pexlechris_Adminer class contains WordPress/Adminer integration (auto login with WordPress credentials)
  * If a developer want to add just JS and/or CSS in head, he/she can just use the action pexlechris_adminer_head.
  * See plugin's FAQs, for more.
  * @since 2.1.0
  * @link Documentation URL.
  * @link Adminer' plugins Documentation URL.
  * @link Adminer' extensions Documentation URL.

Can I limit access to some table/DB ?

The answer in this question is complicated.
The best solution is to create a Database User with the appropriate privileges.
Maybe you can do it also with WordPress actions.

Why is Adminer better than phpMyAdmin?

Replace phpMyAdmin with Adminer and you will get a tidier user interface, better support for MySQL features, higher performance and more security. See detailed comparison.
Adminer development priorities are: 1. Security, 2. User experience, 3. Performance, 4. Feature set, 5. Size.

I remember MySQLDumper was one of the best standalone Backup softwares back then and since they stopped supporting it I was lucky to find Adminer as an equivalent and even better than MySQLDumper. I never thought there would be a Wordpress plugin for it. the plugin just made it way easier to use and also safer comparing to the standalone version.

I had to change the Administration Email Address within the database because the email NEVER gets sent when you use the WP option.I didnt have access to cPanel so this saved the day and made it easy.Will be using this from now on

I've tried other Adminer solutions over the years - always having various connectivity issues, often being unable to connect to the DB. This one always seems to connect correctly - great job!

This comes in very handy when working on a client site where you do not directly have access to the database and need to query, inspect, or alter any data or structures. Adminer has been my client of choice for yonks so I can not thank you enough for making it easy to set it up through a plugin! :8
