Complete Guide to Using Code Snippets with WordPress

 

If you are a WordPress user, you may have found yourself needing to add custom code to your website. Code snippets can be a great solution for this. Code snippets are small pieces of code that can be added to your WordPress website to add new functionality or modify existing functionality. In this blog post, we will explain how to use the plugin Code Snippets with WordPress.

Code Snippets is a popular WordPress plugin that makes it easy to add custom code to your WordPress website. It provides a user-friendly interface for managing and organizing your code snippets. With Code Snippets, you can easily add, modify, and remove code snippets without ever having to edit your theme or plugin files.

Here’s how to use Code Snippets with WordPress:

Step 1: Install the Code Snippets Plugin First, you need to install and activate the Code Snippets plugin. To do this, go to Plugins > Add New in your WordPress dashboard. Search for Code Snippets and click the Install Now button. Once the installation is complete, click the Activate button.

Step 2: Add a New Code Snippet To add a new code snippet, go to Snippets > Add New in your WordPress dashboard. Give your snippet a name and paste your code into the code box. You can also add a description to help you remember what the code does.

For example, let’s say you want to add a custom header to your website. You can use the following code snippet:

				
					
add_action( 'wp_head', 'custom_header' );
function custom_header() {
   echo '<header><h1>Welcome to my website</h1></header>';
}


				
			

Step 3: Assign the Code Snippet to a Website Area Next, choose where you want to apply the code snippet. You can choose to run the code on the entire website or on specific pages, posts, or custom post types. You can also choose to run the code only on certain days or at certain times.

For example, if you only want to display the custom header on the homepage, you can use the following code snippet:

				
					add_action( 'wp_head', 'custom_header' );
function custom_header() {
   if( is_front_page() ) {
      echo '<header><h1>Welcome to my website</h1></header>';
   }
}


				
			

Step 4: Activate the Code Snippet Once you have configured the snippet settings, click the Save Changes and Activate button. Your code snippet is now active on your website.

Step 5: Modify or Delete a Code Snippet To modify or delete a code snippet, go to Snippets > All Snippets in your WordPress dashboard. Find the snippet you want to modify or delete and click on the corresponding button.

For example, if you want to modify the custom header code snippet to change the color of the header text, you can use the following code snippet:

				
					add_action( 'wp_head', 'custom_header' );
function custom_header() {
   if( is_front_page() ) {
      echo '<header><h1 style="color: blue;">Welcome to my website</h1></header>';
   }
}


				
			

Code Snippets is a powerful tool for WordPress users who need to add custom code to their websites. With Code Snippets, you can easily manage and organize your code snippets, making it easier to add, modify, and remove code snippets as needed.

One example of how Code Snippets can be used is to add custom post types to your website. Custom post types allow you to create new content types that are not available by default in WordPress, such as portfolios, events, or recipes. To add a custom post type using Code Snippets, you can use the following code snippet:

				
					add_action( 'init', 'custom_post_type' );
    function custom_post_type() {
    $labels = array(
    'name' => __( 'Portfolio' ),
    'singular_name' => __( 'Portfolio' ),
    'menu_name' => __( 'Portfolio' ),
    'all_items' => __( 'All Portfolios' ),
    'add_new' => __( 'Add New' ),
    'add_new_item' => __( 'Add New Portfolio Item' ),
    'edit_item' => __( 'Edit Portfolio Item' ),
    'new_item' => __( 'New Portfolio Item' ),
    'view_item' => __( 'View Portfolio Item' ),
    'search_items' => __( 'Search Portfolio Items' ),
    'not_found' => __( 'No Portfolio Items Found' ),
    'not_found_in_trash' => __( 'No Portfolio Items found in Trash' ),
    'parent_item_colon' => ''
    );
    
    $args = array(
    'labels' => $labels,
    'public' => true,
    'has_archive' => true,
    'publicly_queryable' => true,
    'query_var' => true,
    'rewrite' => true,
    'capability_type' => 'post',
    'hierarchical' => false,
    'menu_position' => null,
    'supports' => array(
    'title',
    'editor',
    'thumbnail',
    'excerpt',
    'custom-fields'
    )
    );
    register_post_type( 'portfolio', $args );
}
				
			

This code will create a new custom post type called “Portfolio” with a menu icon in the WordPress dashboard, and it will have custom labels and support for the title, editor, thumbnail, excerpt, and custom fields. You can easily modify or delete this code snippet using Code Snippets.

In addition to adding custom post types, Code Snippets can also be used to add custom functions to your WordPress website. For example, you can use Code Snippets to add a function that disables comments on your website. Here’s the code snippet:

				
					function disable_comments_post_types_support() {
$post_types = get_post_types();
    foreach ($post_types as $post_type) {
        if(post_type_supports($post_type, 'comments')) {
        remove_post_type_support($post_type, 'comments');
        remove_post_type_support($post_type, 'trackbacks');
        }
    }
}
add_action('admin_init', 'disable_comments_post_types_support');
				
			

This code will disable comments and trackbacks on all post types on your website, including posts, pages, and custom post types. You can easily modify or delete this code snippet using Code Snippets.
