Add Open Graph Support to WordPress Page Headers Easily
Explanation
To make your WordPress site look great when shared on social media, you can add Open Graph meta tags. These tags help platforms like Facebook and Twitter display your content with a nice preview.
Here's what the code does:
- It hooks into the wp_head action, which means it adds extra information to the head section of your site's pages.
- It checks if the current page is a single post or page using is_singular(). This ensures Open Graph tags are only added to individual posts or pages, not archives or the homepage.
- It grabs the post's title, description, URL, and featured image. These are the key elements that will show up in the social media preview.
- It outputs these details as Open Graph meta tags, which social media platforms use to generate previews.
If your post has a featured image, it includes that too, making your shared links more visually appealing. The type is set to "article," which is suitable for blog posts and pages.
By adding this code, you enhance how your content appears when shared, potentially attracting more clicks and engagement.
Code
<?php
// Hook into 'wp_head' to add Open Graph meta tags
add_action('wp_head', 'wp_dudecom_add_open_graph_meta_tags');
/**
* Adds Open Graph meta tags to the head section of WordPress pages.
*/
function wp_dudecom_add_open_graph_meta_tags() {
if (is_singular()) {
global $post;
// Ensure the post object is available
if (!isset($post)) {
return;
}
// Get the post title
$og_title = get_the_title($post->ID);
// Get the post description
$og_description = get_the_excerpt($post->ID);
// Get the post URL
$og_url = get_permalink($post->ID);
// Get the post featured image
$og_image = '';
if (has_post_thumbnail($post->ID)) {
$og_image_array = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), 'full');
$og_image = $og_image_array[0];
}
// Output Open Graph meta tags
echo '<meta property="og:title" content="' . esc_attr($og_title) . '" />' . "\n";
echo '<meta property="og:description" content="' . esc_attr($og_description) . '" />' . "\n";
echo '<meta property="og:url" content="' . esc_url($og_url) . '" />' . "\n";
if ($og_image) {
echo '<meta property="og:image" content="' . esc_url($og_image) . '" />' . "\n";
}
echo '<meta property="og:type" content="article" />' . "\n";
echo '<meta property="og:site_name" content="' . esc_attr(get_bloginfo('name')) . '" />' . "\n";
}
}
?>Instructions
File Location: Add the code to your theme's functions.php file or a custom plugin file.
Prerequisites:
- Ensure you have access to your WordPress theme files or a custom plugin file.
- Backup your site before making changes to the code.
Implementation Steps:
- Access your WordPress dashboard and navigate to Appearance > Theme Editor if you are editing the
functions.phpfile. Alternatively, use an FTP client or your hosting file manager to access the file directly. - Locate the
functions.phpfile in your active theme's directory or open your custom plugin file. - Copy the provided code snippet.
- Paste the code at the end of the
functions.phpfile or your custom plugin file. - Save the changes to the file.
- Visit a single post or page on your site and view the page source to ensure the Open Graph meta tags are correctly added in the
<head>section.
