Code Snippets

Here are various Beans code snippets that I find useful. Place these into the child theme functions file.

// Remove site header - https://community.getbeans.io/discussion/remove-header-from-cpt/
beans_remove_action( 'beans_header_partial_template' ); 

//Remove site title
 beans_remove_action( 'beans_site_branding' );

//Remove title tagline 
beans_remove_action( 'beans_site_title_tag' );

// Remove beans editor styling
beans_remove_action( 'beans_add_editor_assets' );

// Remove breadcrumbs.
beans_remove_action( 'beans_breadcrumb' );

// Include when using style.css. Added filemtime to right away force CSS changes.
// Version CSS file in a theme
 wp_enqueue_style( 'theme-styles', get_stylesheet_directory_uri() . '/style.css', array(), filemtime( get_stylesheet_directory() . '/style.css' ) );

/* ----- Remove all page titles, but do not remove post titles.
 https://community.getbeans.io/discussion/remov-title-and-change-archive-h1/ ----*/
 add_action( 'wp', 'setup_document_remove_pagetitle' );
 function setup_document_remove_pagetitle() {
 if ( false === is_single() and !is_home() ) {
 beans_remove_action( 'beans_post_title' );
 }
 }


/* An alternative approach to removing page titles suggested by Tonya: https://community.getbeans.io/discussion/remove-page-titles-but-not-post-titles/ */
beans_add_smart_action('beans_before_posts_loop', 'remove_page_title_on_pages_only' );
function remove_page_title_on_pages_only() {
  if ( is_singular() && is_page() ) {
   remove_all_actions( 'beans_post_header' );
  }
}

// Removes featured image from all pages (posts and pages) except the blog page.
add_action( 'wp', 'beans_child_setup_document' );
function beans_child_setup_document() {
 if ( is_single() or is_page() ) { 
 beans_remove_action( 'beans_post_image' );
 }
}

/* Resize featured images seen on the blog page: 
https://community.getbeans.io/discussion/default-featured-image-size/ --- */
add_filter( 'beans_edit_post_image_args', 'example_post_image_edit_args' );
function example_post_image_edit_args( $args ) {
 return array_merge( $args, array(
 'resize' => array( 300, true ),
 ) );
}

// Blog page Excerpt - 
//THE FOLLOWING CODE needs to be added into an index.php file to work correctly.
//
// https://community.getbeans.io/discussion/how-to-show-post-excerpts/#post-4764
add_filter( 'the_content', 'beans_child_modify_post_content' );
function beans_child_modify_post_content( $content ) {
// Stop here if we are on a single view.
if ( is_singular() )
return $content;
}

// Return the excerpt() if it exists other truncate.
if ( has_excerpt() )
$content = '<p>' . get_the_excerpt() . '</p>';
else
$content = '<p>' . wp_trim_words( get_the_content(), 40, '...' ) . '</p>';

// Return content and readmore.
return $content . '<p>' . beans_post_more_link() . '</p>';
}

I commented out if ( is_singular() || is_admin() ) { as it gave me auto save 
problems in Gutenberg. 
if (!is_archive() ) { or if ( is_singular() ) will hopefully work instead.

/* Modify Continue reading text link to Read more.
https://community.getbeans.io/discussion/modify-wordpress-language/ */
add_filter( 'beans_post_more_link_text_output', 'example_modify_read_more' );
function example_modify_read_more() {
 return 'Read more..';
}

/* Modify >> to ... (dots).
https://community.getbeans.io/discussion/modify-wordpress-language/ */
beans_remove_markup('beans_next_icon[_more_link]');
beans_add_filter('beans_post_more_link_text_output', 'add_dots_after_continue_reading' );

function add_dots_after_continue_reading($continue_reading_text) {
   return $continue_reading_text . '...';
}

An alternative to the above code for adjusting the >> to …

Additional code snippets will be added along the way.
