Database Management tool – Adminer

FAQ

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
  </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.
