Using WordPress Code Snippets

As a WordPress expert, I'm often asked what's the secret to effortless WordPress development. The answer is simple - code snippets.

WordPress code snippets can save you time and energy when developing a website. But how do you make the most of your development workflow without spending all day writing code? Let me show you the advantages of using WordPress code snippets in your project.

In this article, I'll discuss the benefits of using WordPress code snippets and how they can help make your development process easier. You'll learn how to find and utilize pre-written bits of code specifically designed for WordPress projects and how to use them to speed up your development process. I've even added a few of my own code snippets in this article for use in whatever you'd like.

Let's get started.

What Are WordPress Code Snippets?

WordPress code snippets are small pieces of code that can be used to add functionality and customize your WordPress websites. They are usually snippets of PHP, HTML, CSS, or JavaScript that can be added directly to the functions.php file or plugins. Code snippets can help you save time and effort when developing a site by allowing you to implement features quickly without having to write all the code from scratch.

Benefits Of Using Code Snippets On WordPress

Have you ever been told that long-term success in WordPress development requires a lot of hard work? I'm here to tell you it doesn't have to be so hard! With the help of code snippets, you can save time and energy while achieving great results. Code snippets are pieces of code used to add functionality or modify existing features in WordPress. They can be used as part of plugins, themes, or even in your code.

The advantages of using code snippets on WordPress are plentiful. First, they allow for more flexible customization options than those available through plugins and themes alone. By utilizing code snippets, you can make changes to your site's core files without worrying about compatibility issues or other technicalities arising from making changes directly. Additionally, code snippets can help speed up development time by doing away with tedious coding tasks such as writing out entire functions from scratch. Finally, since many developers share their snippets online for free, there's no need to reinvent the wheel when creating a feature - find a snippet that does what you need and implement it!

Using code snippets on WordPress is an effective way to streamline development processes while maintaining control over your website’s design and functionality. Not only do they provide users with more customization options, but they also save time and energy by eliminating repetitive tasks. Moreover, thanks to the abundance of freely available snippets shared online by developers, finding exactly what you need has never been easier! This makes them a perfect tool for any WordPress developer looking to simplify their workflow without sacrificing quality or control over their site's design and functionality.

How To Add Code Snippets To Your Site

Adding code snippets to your WordPress site is an effective way to get the most out of the platform. It can help you achieve certain tasks on your website faster and make developing websites easier. To add code snippets to your WordPress site, there are a few things you need to know.

The first step is to determine the best route for you to manage and add code snippets to your website. There are two ways of adding snippets to your WordPress website, utilizing the functions.php file inside your theme folder or using a plugin designed to handle code snippets directly. I've done both methods, and for ease of use, using a plugin designed to handle code snippets is generally the better choice.

The most popular code snippet plugins include Code Snippets Pro, WPCode, and WPCodeBox. Each plugin provides different features for managing and inserting code snippets into your website.

Code Snippet plugins allow you to quickly add code snippets to your site without having to copy-paste them into the source code manually. It also provides an easy way to manage existing snippets and delete or disable them when they're no longer needed.

These popular code snippet plugins efficiently integrate custom functionality into your WordPress website without worrying about entering the code incorrectly or forgetting it altogether. Most plugins allow you to revert your saved snippet if there are any errors or problems with the code. Some even have built-in checkers to let you know if there are any syntax errors with your code. Adding these plugins lets you quickly and easily add code snippets to your site with just a few clicks.

Tips For Writing Quality WordPress Code Snippets

WordPress code snippets are an essential part of developing a custom WordPress website. They allow you to add extra functionality, customize the appearance of your site, and improve its performance. However, it's essential to remember that coding mistakes can lead to unexpected results and even break your site.

To ensure your code snippets work properly and efficiently, here are some tips to keep in mind:

  • Always Double-Check Syntax Before Running Code - When you're adding a new custom code snippet to your WordPress site, always double-check its syntax before running it on your site. Syntax errors can prevent your code from working correctly and can be challenging to diagnose and fix. A small typo or a missing semicolon can cause significant issues, so check the syntax thoroughly.
  • Back Up Your Site Before Installing New Code - When adding new plugins or code snippets to your WordPress site, back up your site first. This will allow you to revert any changes if something goes wrong quickly. You can use a backup plugin or manually back up your site to ensure you have a copy of your site before making any changes.
  • Use a Development Environment - When working on code snippets for your WordPress site, it's always best to test them in a staging or development environment before adding them to your site. This will allow you to catch errors before they affect your site. You can set up a local WordPress installation or use a staging site provided by your hosting provider to test your snippet first, before applying it to your production site.

Common Mistakes When Working With WordPress Code

While working with WordPress code snippets can be challenging, avoiding common mistakes can make the process more manageable.

Here are some of the most common mistakes and how to avoid them:

  • Copying and Pasting Code Snippets - Copying and pasting code snippets from the web into your theme's functions file or a snippet plugin may seem like a quick fix. However, doing so is never advisable without first testing the code in a staging or development environment. This will help you catch any conflicts or issues before they break your site.
  • Improperly Formatted Code Snippets - When adding code snippets to your theme's functions file, ensure they are properly formatted and indented. Poorly formatted code can be challenging to read and understand, making it harder to diagnose any issues. Make sure your code is easy to read and follow.

Writing quality WordPress code snippets requires attention to detail and careful planning. By following best practices, double-checking syntax, and testing your code in a development environment, you can ensure your code snippets work smoothly and efficiently, improving the functionality and appearance of your WordPress site.

Hire An Expert When Necessary

When looking to develop a WordPress website, there are many advantages to using code snippets. It can save time and money, and you can easily add custom functionality. However, there are times when it is wise to hire an expert in WordPress development.

A WordPress expert may be able to provide more complex solutions for your project that would be difficult or impossible for the average user to do on their own. They have experience with coding and can help you understand how to integrate your code into the website properly. They also know what plugins and other tools are available to make development easier and faster. In addition, they can provide advice on best practices for developing a secure and reliable website.

Conclusion

Frequently Asked Questions

How do I troubleshoot an issue caused by a code snippet?

Troubleshooting any issue caused by a code snippet can be a complicated task. As an experienced WordPress developer, I know firsthand the challenges of deciphering code snippets and resolving their issues. Fortunately, there are some steps you can take to make troubleshooting easier.

First, it's important to understand the code snippet itself – its purpose, how it works, and what plugins or themes it may interact with. Once you have that knowledge, you should start by testing the snippet in an isolated environment to check for errors and malfunctions. If the snippet does not work properly when tested alone, you may be able to identify and fix the issue yourself.

If the problem persists even after testing in an isolated environment, it's time to do deeper detective work. Look for any other plugins or themes conflicting with your code snippet, and try removing them one at a time until you find the culprit. Additionally, search online forums or ask your peers for advice on how they would approach solving this kind of issue.

What is the best method to store and manage my code snippets?

There are a few options for storing your code snippets. The easiest method is keeping them on your website in a plugin designed to manage and handle code snippets. All code snippet plugins allow you to keep snippets in the database without activating them, so this is an easy and quick method for storing them. Be sure that website is backed up regularly so your hard work stays safe.

Another method is to use an application designed to store code on your computer. Several free and paid options are available, primarily for programmers, but anyone can use them to store their code, and most come with the added benefit of syntax error highlighting.

You can also keep it simple and store them in text files. Just be certain they are plain text, not rich text, as the rich text will add carriage returns or adjust apostrophes which can break your code.

What is the best way to keep my code snippets up-to-date?

Coding standards change over time, and the need to keep your snippets updated will also arise. The best method that I've found for keeping your snippets updated is to check for errors with your processed snippets often simply. This means enabling error reporting in WordPress to ensure that any errors coming up do not relate directly to your snippets.

It's a good practice to do this every few months, but you also want to do this anytime you update any of the daemons for your server or if your hosting provider does. For instance, if you upgrade PHP, be certain to enable error debugging because a function in your PHP snippet can no longer be supported. If it's major enough, it can break your website completely.

I would also suggest rewriting your snippets often. As you progress as a developer, you'll learn how to code more efficiently and achieve the same outcome with less code or new faster methods of processing information. By rewriting your snippets as you progress, you'll also have the added benefit of keeping the updated to current standards.

What are the best practices for debugging code snippets?

The first step in debugging is ensuring your code snippets are up-to-date. By keeping your code snippets updated, you can quickly identify any changes or additions that could cause problems down the line. Using version control systems such as Git can help you keep track of all your code snippets, so you can easily roll back to earlier versions if necessary. Additionally, ensure that any third-party libraries or plugins you use are up-to-date and compatible with your current version of WordPress.

The next step is thoroughly testing your code snippet before deploying it on a live site. This includes testing for compatibility with different browsers, devices, and operating systems; ensuring proper functionality; and fixing any existing bugs. Debugging tools such as PHPStorm can help you quickly identify and solve errors in your code snippet, while plugins like Debug Bar make troubleshooting WordPress easier by giving you an inside look at what's happening behind the scenes on your website.

Finally, it’s important to stay organized when debugging code snippets to avoid missing anything important. Keeping detailed notes of what steps you took during the debugging process will help ensure nothing gets overlooked - plus, it will make future debugging tasks much easier!

Bonus Code Snippets

Here are a few code snippets I often use in developing custom WordPress websites for my clients.

Custom Post Type Options Page - This snippet will create a menu item that can be used with the Advanced Custom Felids options page. Add this snippet first and change the items in all caps to fit your needs. Then inside ACF, select the options page, then your new custom post type.

<?php 
if( function_exists('acf_add_options_page') ) {
    acf_add_options_page(array(
        'page_title'     => 'PAGE TITLE',
        'menu_title'    => 'MENU TITLE',
        'menu_slug'     => 'SLUG',
        'capability'    => 'edit_posts',
        'redirect'        => false
    ));
}

Add SVG Support - This snippet will add SVG support directly into the WordPress media manager, which is not standard with WordPress. Plenty of plugins add this functionality, but this will do the same without all the extras of installing another plugin.

<?php 
add_filter( 'wp_check_filetype_and_ext', function($data, $file, $filename, $mimes) {
  global $wp_version;
  if ( $wp_version !== '4.7.1' ) {
     return $data;
  }
  $filetype = wp_check_filetype( $filename, $mimes );
  return [
      'ext'             => $filetype['ext'],
      'type'            => $filetype['type'],
      'proper_filename' => $data['proper_filename']
  ];
}, 10, 4 );
function cc_mime_types( $mimes ){
  $mimes['svg'] = 'image/svg+xml';
  return $mimes;
}
add_filter( 'upload_mimes', 'cc_mime_types' );
function fix_svg() {
  echo '<style type="text/css">
        .attachment-266x266, .thumbnail img {
             width: 100% !important;
             height: auto !important;
        }
        </style>';
}
add_action( 'admin_head', 'fix_svg' );

Duplicate Page & Posts - This one does exactly what it sounds like. It'll add a link under a page or post, allowing you to duplicate it. Again, plenty of plugins do this, but why add the extra bloat if it isn't needed?

<?php 
add_filter( 'post_row_actions', 'wpcode_snippet_duplicate_post_link', 10, 2 );
add_filter( 'page_row_actions', 'wpcode_snippet_duplicate_post_link', 10, 2 );
if ( ! function_exists( 'wpcode_snippet_duplicate_post_link' ) ) {
    function wpcode_snippet_duplicate_post_link( $actions, $post ) {
        $post_type_object = get_post_type_object( $post->post_type );
        if ( null === $post_type_object || ! current_user_can( $post_type_object->cap->create_posts ) ) {
            return $actions;
        }
        $url = wp_nonce_url(
            add_query_arg(
                array(
                    'action'  => 'wpcode_snippet_duplicate_post',
                    'post_id' => $post->ID,
                ),
                'admin.php'
            ),
            'wpcode_duplicate_post_' . $post->ID,
            'wpcode_duplicate_nonce'
        );
        $actions['wpcode_duplicate'] = '<a href="' . $url . '" title="Duplicate item" rel="permalink">Duplicate</a>';
        return $actions;
    }
}
add_action( 'admin_action_wpcode_snippet_duplicate_post', function () {
    if ( empty( $_GET['post_id'] ) ) {
        wp_die( 'No post id set for the duplicate action.' );
    }
    $post_id = absint( $_GET['post_id'] );
    if ( ! isset( $_GET['wpcode_duplicate_nonce'] ) || ! wp_verify_nonce( $_GET['wpcode_duplicate_nonce'], 'wpcode_duplicate_post_' . $post_id ) ) {
        wp_die( 'The link you followed has expired, please try again.' );
    }
    
    $post = get_post( $post_id );
    if ( $post ) {
        $current_user = wp_get_current_user();
        $new_post     = array(
            'comment_status' => $post->comment_status,
            'menu_order'     => $post->menu_order,
            'ping_status'    => $post->ping_status,
            'post_author'    => $current_user->ID,
            'post_content'   => $post->post_content,
            'post_excerpt'   => $post->post_excerpt,
            'post_name'      => $post->post_name,
            'post_parent'    => $post->post_parent,
            'post_password'  => $post->post_password,
            'post_status'    => 'draft',
            'post_title'     => $post->post_title . ' (copy)',
            'post_type'      => $post->post_type,
            'to_ping'        => $post->to_ping,
        );
        $duplicate_id = wp_insert_post( $new_post );
        $taxonomies = get_object_taxonomies( get_post_type( $post ) );
        if ( $taxonomies ) {
            foreach ( $taxonomies as $taxonomy ) {
                $post_terms = wp_get_object_terms( $post_id, $taxonomy, array( 'fields' => 'slugs' ) );
                wp_set_object_terms( $duplicate_id, $post_terms, $taxonomy );
            }
        }
        $post_meta = get_post_meta( $post_id );
        if ( $post_meta ) {
            foreach ( $post_meta as $meta_key => $meta_values ) {
                if ( '_wp_old_slug' === $meta_key ) {
                    continue;
                }
                foreach ( $meta_values as $meta_value ) {
                    add_post_meta( $duplicate_id, $meta_key, $meta_value );
                }
            }
        }
        wp_safe_redirect(
            add_query_arg(
                array(
                    'action' => 'edit',
                    'post'   => $duplicate_id
                ),
                admin_url( 'post.php' )
            )
        );
        exit;
    } else {
        wp_die( 'Error loading post for duplication, please try again.' );
    }
} );
