Are you trying to find some WordPress code snippets to enhance your website?
Using code snippets on your WordPress site allows you to create unique designs and functionalities that themes and plugins might not offer. These snippets can also boost security and make the admin dashboard easier to use.
In this article, we’ll show you a list of the best WordPress code snippets for beginners.
Why Use Code Snippets in WordPress?
Adding code snippets to your WordPress site can help you customize your website in many ways. For example, you can change the color of text selection with a simple CSS snippet. Snippets can also improve your site’s performance and speed by reducing the need for multiple plugins. They also help you learn coding and use the vast number of free code snippets shared by the WordPress community.
Here are some useful WordPress code snippets for beginners:
- Allow SVG File Upload
SVG (Scalable Vector Graphics) files are smaller and lighter than JPEG or PNG files, improving your site’s speed. However, WordPress doesn’t allow SVG uploads by default due to security concerns. To upload SVG files, add this code snippet to your site:
if (!current_user_can(‘administrator’)) {
return $upload_mimes;
}
$upload_mimes[‘svg’] = ‘image/svg+xml’;
$upload_mimes[‘svgz’] = ‘image/svg+xml’;
return $upload_mimes;
});
add_filter(‘wp_check_filetype_and_ext’, function ($wp_check_filetype_and_ext, $file, $filename, $mimes, $real_mime) {
if (!$wp_check_filetype_and_ext[‘type’]) {
$check_filetype = wp_check_filetype($filename, $mimes);
$ext = $check_filetype[‘ext’];
$type = $check_filetype[‘type’];
$proper_filename = $filename;
if ($type && 0 === strpos($type, ‘image/’) && ‘svg’ !== $ext) {
$ext = false;
$type = false;
}
$wp_check_filetype_and_ext = compact(‘ext’, ‘type’, ‘proper_filename’);
}
return $wp_check_filetype_and_ext;
}, 10, 5);
Add this code to your theme’s functions.php file or use a code snippets plugin like WPCode.

$content = ‘<p>’ . get_the_post_thumbnail($post->ID) . ‘</p>’ . $content;
}
return $content;
}
add_filter(‘the_excerpt_rss’, ‘wpcode_snippet_rss_post_thumbnail’);
add_filter(‘the_content_feed’, ‘wpcode_snippet_rss_post_thumbnail’);

$wp_admin_bar->add_node(array(
‘id’ => ‘my-account’,
‘title’ => str_replace(‘Howdy,’, $new_howdy, $my_account->title),
));
