Menu items – featured images / thumbnails / image placeholder (if any)

Note: many display options are also available by simply using the relevant shortcode attributes or setting options in WPPizza -> Layout instead of using filters

CSS Targeting

• element ID: #wppizza-article-img-[post_id]
• element class: .wppizza-article-image
• Use your browsers element inspector to identify all classes and id’s

if you simply want to edit some styles/layout (text-sizes, color, margins, paddings etc etc ) it is strongly recommended to use css instead of filters/actions. Please refer to Modify Styles/Layout

Structure

/* featured images */
 <div>
	<img src='path/to/image' />
 </div>

/* placeholder image (uses css to display placeholder) */
 <div>
	<div>[empty]</div> 
 </div>

Filters available

apply filters by adding them to your child-theme’s functions.php (notes regarding functions.php).

• filter name: wppizza_filter_post_thumbnail_class
  purpose: modify classes used

  @param: $classes array (array of classes used in wrapper div)
  @param: $post_data array (array of post_data)

  @return: array

  examples:

  
  add_filter('wppizza_filter_post_thumbnail_class', 'prefix_filter_post_thumbnail_class', 10 ,2);
  function prefix_filter_post_thumbnail_class($classes, $post_data){
  	/* adding your own class name */
  	$classes[] ='my-class';
  return $classes;
  }
  		

• filter name: wppizza_filter_post_title_markup
  purpose: modify output of element

  @param: $markup array (array of markup elements)
  @param: $style string (style used – default|responsive|grid)
  @param: $has_thumbnail bool (true|false)
  @param: $has_placeholder bool (true|false)
  @return: array

  examples:

  
  
  add_filter('wppizza_filter_post_thumbnail_markup', 'prefix_filter_post_thumbnail_markup', 10 ,4);
  function prefix_filter_post_thumbnail_markup($markup, $style, $has_thumbnail, $has_placeholder){
  
  	/* 
  		notes: 
  		use print_r($markup) to view markup array keys with their respective markup
  		use print_r($style) to view style used ( default|responsive|grid )
  		use print_r($has_thumbnail) to find out if post should display thumbnail
  		use print_r($has_placeholder) to find out if post should display placeholder
  		use global $wppizza_options; to access all options/settings/localization strings etc set in the plugin

  	$markup['my_new_markup'] = '<p>more text after</p>'; 
  
  	/* example: adding a paragraph BEFORE all elements */
  	$new_markup = array();
