What am i missing? ‘tag’ may be a valid argument for get_posts() via WP_Query, but requires the tag slug in that case. Try using ‘tag_id’ instead. get_posts() apparently enables ‘category’, but expects the the ID, even though in WP_Query the same argument is ‘cat’ (vs. ‘category_name’, et al). A little confusing, perhaps, altogether. I know … Read more
While you might believe that you have an error in WordPress, the actual problem actually is on facebooks end. When they already have an image, you need to force a rescrape (iirc) via their Open Graph Debugger(?). facebook caches images of various sizes by Url. Meaning that if you already served an image, they already … Read more
Use the following CSS to target only the banner image on single posts: body.sinlge .size-banner-image { width:100%; } This will only work if your <div class=”container”> element is not restricted in its width, else the banner will only stretch to the container width.
As you are storing posts IDs in meta fields of another post (let’s call this post “the main post”), you can get that meta field and if it is empty, just avoid the use of get_the_post_thumbnail(). (For the next examples, I suppose that you are stroing one post ID in one meta field of the … Read more
the_post_thumbnail() echos a complete HTML <img> tag, not just the URL of the image. So, just use: <?php the_post_thumbnail ()?> rather than <img src=”https://wordpress.stackexchange.com/questions/259813/<?php the_post_thumbnail () ?>”>
In your case, you need to add custom fields to the metabox. The full reference code of the filter is here: ‘admin_post_thumbnail_html’ – https://developer.wordpress.org/reference/hooks/admin_post_thumbnail_html/. Let’s add an image title: <?php add_filter(‘admin_post_thumbnail_html’, ‘custom_featured_image_field’, 10, 2); function custom_featured_image_field($content, $post_id) { $custom_name = ‘custom_featured_image_title’; $custom_value = esc_attr(get_post_meta($post_id, $custom_name, true)); $output = sprintf( ‘<br><input type=“text” id=”%1$s” name=”%1$s” value=”%2$s”>’, $custom_name, … Read more
Make sure to use echo with get_the_post_thumbnail(): echo get_the_post_thumbnail(64 , ‘post-thumbnail’, array( ‘class’ => ‘img-format-big’ ) ); In WordPress, a rule of thumb (no pun intended) is to use echo with functions prefixed with get_. Functions prefixed with the_ on the other hand, display their output immediately (e.g. the_post_thumbnail() ).
As @belinus mentioned, you can assign multiple categories to a post, so you have to decide which one to pass to the_post_thumbnail(). One approach would be to use get_the_category(), which returns an array, then grabbing the first result from that function as your thumbnail size: $categories = get_the_category(); $thumbnail_cat = ! empty( $categories[0]->slug ) ? … Read more
I can’t speak for the size of the image, but I assume small images that have a dimension about 50px should have the size around 5 or 10kb. You can add your own custom size to your theme: add_image_size( ‘tiny-thumbnails’, 50, 50, true ); Setting the fourth parameter to true will force the WordPress to … Read more
You have to echo it out: echo get_the_post_thumbnail(); Perhaps you meant to use the_post_thumbnail(); https://developer.wordpress.org/reference/functions/the_post_thumbnail/
