Restrict post to WordPress user

Over the that weekend I had been using WordPress to take notes at WordCamp Orange County and realized that WordPress’ block editor is useful as a note taking environment. But what If I don’t want these notes to be public?

Using a template to restrict access

I duplicated TwentyNineteen’s single.php template and wrapped the loop in a conditional tag is_user_logged_in().

The code

<?php
/**
 * Single post and page template for restricting the title and content unless the user is logged in
 * Sources:

 * https://codex.wordpress.org/Conditional_Tags

 * @link https://developer.wordpress.org/themes/basics/template-hierarchy/#single-post
 *
 * @package WordPress
 * @subpackage Twenty_Nineteen
 * @since 1.0.0
 *
 * License: GPL 2 or later
 *
 * Template Name: Log in Required
 * Template Post Type: post, page
 *
 */

get_header();
?>

	<div id="primary" class="content-area">
		<main id="main" class="site-main">

<?php
	if ( is_user_logged_in() ) {  // check if user is logged in

/* * 
 * Start the Loop 
 * This example  uses TwentyNineteen for the loop, if using a different theme subsitute that loop here.
 * */
		while ( have_posts() ) :
			the_post();

			get_template_part( 'template-parts/content/content', 'single' );

			if ( is_singular( 'attachment' ) ) {
				// Parent post navigation.
				the_post_navigation(
					array(
						/* translators: %s: parent post link */
						'prev_text' => sprintf( __( '<span class="meta-nav">Published in</span><span class="post-title">%s</span>', 'twentynineteen' ), '%title' ),
					)
				);
			} elseif ( is_singular( 'post' ) ) {
				// Previous/next post navigation.
				the_post_navigation(
					array(
						'next_text' => '<span class="meta-nav" aria-hidden="true">' . __( 'Next Post', 'twentynineteen' ) . '</span> ' .
							'<span class="screen-reader-text">' . __( 'Next post:', 'twentynineteen' ) . '</span> <br/>' .
							'<span class="post-title">%title</span>',
						'prev_text' => '<span class="meta-nav" aria-hidden="true">' . __( 'Previous Post', 'twentynineteen' ) . '</span> ' .
							'<span class="screen-reader-text">' . __( 'Previous post:', 'twentynineteen' ) . '</span> <br/>' .
							'<span class="post-title">%title</span>',
					)
				);
			}

			// If comments are open or we have at least one comment, load up the comment template.
			if ( comments_open() || get_comments_number() ) {
				comments_template();
			}

		endwhile; // End of the TwentyNineteen  loop.
    
	} else { // If not logged in present a link to log into the site
		echo '<p style="text-align: center;"><a href="' .  wp_login_url( get_permalink() ) . '" title="Login">Log in to view this post</a></p>';
	}
		?>

		</main><!-- #main -->
	</div><!-- #primary -->

<?php
get_footer();

How does this code work?

Simply put, is_user_logged in() will check if the user is logged before it displays the post. If not they’re presented with a link to log in.

Left, the user is logged in. Right, post content and title will not display.

What it doesn’t do?

Using this post and page template will only restrict the post page. The excerpt or content will still display on archive pages unless those loops run a similar conditional check.

Creating a custom attachment loop for images and other files in WordPress

While building an attachment.php template for a project I opted to customize the loop to properly display an image within a figure tag and the caption within figcaption to aid accessibility.

Additionally if the file is not an image it will provide a button that can be styled along with a mime type.

The following code would have to be placed within the loop.

<?php 
if ( wp_attachment_is_image() ) {

	// Set the image's ID to an array so it can be reused later
	$image_id = get_the_ID();
	$caption = wp_get_attachment_caption( $image_id );

	echo '<figure>';

		// Displays the large version of the image if available
		echo wp_get_attachment_image( $image_id, 'large' );

		// if no caption is set or the value is null do nothing and don't display the empty tags
		if (!empty($caption) ) {
			echo '<figcaption>' . $caption . '</figcaption>';
		}

	echo '</figure>';

} else {

	// If the attachment is not an image display a button and mime type.
	$attachment_id = get_the_ID();

	$attachment_url = wp_get_attachment_url( $attachment_id ); 

	echo '<button type="button"><a href="' . $attachment_url . '" target="_blank">' . get_the_title( $attachment_id ) . '</a></button> ';

	echo '<span class="mime-type">' . get_post_mime_type( $attachment_id ) . '</span>';

}
?>

Overriding Gutenberg’s default editor width and font

By default Gutenberg sets the editor width to 580px on the desktop unless the browser window is narrower. Since Kubrick’s post content area is 480px we’ll need to override the width so text wrapping occurs at the same width as the final post. for that we simply set new declarations for the wp-block class tag.

Creating smaller buttons for Gutenberg

This week I ran into a practical problem with WordPress’ default button blocks being simply too large for certain situations. Fortunately, extending Gutenberg blocks isn’t too difficult. Following the Gutenberg Handbook I’ll be adding to my existing files. These files have been enqueued previously to my theme.
