FAQ

Is it safe?

Yes, because only administrators have access to WP Adminer. If a guest tries 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.

WP Adminer is stuck in an endless loop, constantly refreshing the page without stopping. What is the issue?

This issue maybe is due to the caching engine that your browser OR server uses!
* You can try to whitelist the WP Adminer URL, OR
* You can change the WP Adminer URL to a URL that is already whitelisted. For example:
define( ‘PEXLECHRIS_ADMINER_SLUG’, ‘wp-admin/adminer’);

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
     </script>
     <style>
        /* Place your CSS code here */
     </style>
     <?php
  });

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.

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.
Read more in this support ticket.

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.

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.

Didn’t install for me

davidforrest April 29, 2024 5 replies

Followed instructions on WP dashboard to install plugin. Adminer link installed on top menu and in the Tools menu of Dashboard. Clicking link = “The requested URL was not found on this server” Don’t know why. The linked folder for site/wp-adminer was not found with a file manager on my server. Nothing found about this in the forums. PexleChris looked at the installation and told me there was a missing .htaccess file in the public_html directory. Not sure why Wordpress didn’t put that file in there when I installed Wordpress. Thank you PexleChris! File contents say “dynamically generated” as follows …………………………………………………… BEGIN WordPress The directives (lines) between “BEGIN WordPress” and “END WordPress” are dynamically generated, and should only be modified via WordPress filters. Any changes to the directives between these markers will be overwritten. RewriteEngine On RewriteRule .* – [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}] RewriteBase / RewriteRule ^index.php$ – [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] END WordPress …………………………………………………………….

Brilliant !

I often have to change some settings in the database of my customers (website owner). Often they don’t know their cPanel access, or this cPanel require a double authentication (with SMS) and they are not around to communicate this code to me. Adminer make it a breeze to connect to the Database, and it is now seamlessly integrated within WordPress (no need to fill in login / password. Kudos guys !

Solid database admin tool that has always worked

Andrew Mead January 24, 2024

This is a solid database admin tool that has always worked for me, even on a variety of client sites running on a variety of hosting. Much appreciated.

Working as expected!

Great plugin! This is what i was looking for.

Never thought there would be a WordPress plugin for the standalone version!!

euro11 April 13, 2023

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.

Brilliant

wealthy December 30, 2022

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
