Disable Gutenberg

by ·

Two years ago, WordPress introduced Gutenberg block editor together with the release of WordPress version 5.0. Gutenberg essentially became the default editor starting with WordPress version 5.0. While many people love the Gutenberg editor, some people hate it. If you’re one of the many people who hate the Gutenberg editor, you can simply disable it by installing a plugin called Disable Gutenberg. This plugin will revert back to the classic editor.

Once installed, you should be able to see the Classic editor.

After working with Gutenberg for so long, I forgot the speed and agility of the classic editor. It’s much faster.

WordPress Read Only

by ·

Here’s how to create a WordPress site that’s read only. You will not be able to create, update and delete posts.

  1. Login to MySQL or MariaDB.
  2. Choose mysql database.
  3. Create a new user called ‘wpro’ for WordPress read only.
  4. Grant select permissions to all tables in ‘wordpress’ database.
  5. Flush privileges to commit your changes.
mariadb -u root -p
use mysql;
create user 'wpro'@'localhost' identified by 'yourpassword';
grant select on wordpress.* to 'wpro'@'localhost';
flush privileges;

In MySQL or MariaDB, you have to terminate all commands with a semicolon.

Now edit your WordPress wp-config.php file. vim /var/www/wordpress/wp-config.php.

/** MySQL database username */
define('DB_USER', 'wpro');
 
/** MySQL database password */
define('DB_PASSWORD', 'yourpassword');

After saving the wp-config.php file, everything should work just like before, except that you will not be able to save, publish or delete posts, pages, or add or delete media files to your WordPress site. It’s working as intended.

Custom Breadcrumbs

by ·

I’ve customized my breadcrumbs. Add code to functions.php.

add_filter('genesis_breadcrumb_args', 'customize_breadcrumbs');
function customize_breadcrumbs($args) {
    $args['labels']['prefix'] = 'Home';
    $args['home'] = '';
    $args['sep'] = '/';
    return $args;
}

Now it doesn’t say Home/Home on the front page.

Center Search Widget

by ·

Here’s how to center the Search widget in a WordPress Page or a post. This applies only if you’re using the default Search Widget. Div classes may vary based on theme being used. The CSS example below may not work for your theme. Check your theme’s source code to be sure.

.entry-content .wp-block-search {
  display:block;
  margin-left:auto;
  margin-right:auto;
  text-align: center;
}
.entry-content .wp-block-search label {
  display:none;
}
.entry-content .wp-block-search input {
  width:250px;
}

The CSS above centers the search block. It suppresses the search label, and finally sets the form’s input to a fixed width of 250px.

Revolution Theme

by ·

I’m now using the Revolution theme from StudioPress. It’s a minimal design with lots of whitespace. The default font is Playfair Display which highlights headlines and blockquotes. The Playfair Display is available from Google Fonts if you’re interested. I think it’s a perfect theme for a photography blog. Although the theme seems to invite you to write more, something I haven’t been doing lately. And before I sign off, let’s take a look at what a blockquote looks like. Not bad at all. A beautiful theme.

It’s a minimal design with lots of whitespace.

Here’s how to display Copyright years in the footer section if you’re using the Genesis theme.

[footer_copyright first="2002"]

Result:

Copyright © 2002–2020

The current year is dynamic. It will display 2021 a year from now. The first year is always fixed.

WordPress Posts Revision

How to turn on post revisions in WordPress. Edit wp-config.php.

/** WordPress Revisions */
define('WP_POST_REVISIONS', false);

Change to:

/** WordPress Revisions */
define('WP_POST_REVISIONS', 10);

10 is the number of revisions you want to keep.
