Code Snippets in WordPress: What You Should Have Known

Code snippets are unique in WordPress. Small code chunks, called Code Snippets, help users repeat WordPress tasks without learning how to code.

Let’s consider an example.

Without changing a Theme’s core in WordPress by using code snippets – you have the option:

To change the color scheme with CSS code snippets.
To integrate 3rd party tools with WordPress, such as Google Search Console and Analytics.
To help users define SEO stats, such as a document’s Type.
To turn off specific functionality in WordPress, such as the admin bar.
To help users automatically redirect HTTP traffic to HTTPs.

Let’s describe code snippets in more detail.

Introduction to Code Snippets

In WordPress, only some users can write source codes.

If users with no knowledge of coding proceed to change WordPress, code snippets are the way to go. In this case, users pick a code snippet, embed it in WordPress, and save changes. Without learning to code or going through complex infrastructure, WordPress adopts the expected changes.

So, as WordPress supports code snippets, users can perform various tasks with code chunks. The WordPress customizer interface helps users place code snippets. After you’ve put a snippet, saving changes will affect your site’s attributes according to the code snippet. WordPress overrides its default behavior with the snippet’s characteristics in this case.

Use Cases of Code Snippets in WordPress

Designing

Code snippets can help users change WordPress design elements. For example, every theme supports changes to the Functions.PHP file. A code snippet that helps users change a Theme’s design options can help you shift Functions.PHP without learning how to change the theme’s core interface or complex infrastructure.

Changing default options

If you don’t like your Theme’s Header or Footer, placing a code chunk can help you hide. Be aware that if you need to learn how to proceed, don’t change WordPress.

Security purposes

Did you want to hide your site’s login page? Code snippets can help.

Once a code chunk helps you hide your site’s login page, you can avoid brute-force attacks on WordPress. The entire process takes little time.

WordPress maintenance

Simple code snippets can help users stop WordPress’ automatic updates. Such maneuvers prevent WordPress conflicts, errors, and maintenance issues.

Errors handling in WordPress

WordPress errors are shown on the front-end interface. For example, if a White Screen of Death occurs, WordPress can start showing errors on the screen.

Sometimes, the errors are more deadly for security reasons. An error can tell attackers how to proceed with exploiting a WordPress website. To strengthen WordPress’ security, code snippets can help admins stop showing errors on the front-end screen.

How to use Code Snippets in WordPress?

Using code snippets in WordPress is simple. All you’ve to do is to find the relevant place.

In WordPress, there are various steps to proceed using code chunks. Let’s explain in more detail.

Use the WordPress default option

Users can quickly use code chunks by using the WordPress default interface. This option, called WordPress Advanced CSS, is available on the Appearance tab.

In this case, access the required page at Appearance -> Customize. The option below helps users place code chunks. Once they’re done, don’t forget to save changes. Be aware that syntax errors in codes can destroy WordPress.

Use a Child Theme

A child Theme inherits basic functionality from a Parent Theme. In WordPress, the concept of using child Themes is old school. It helps users avoid errors.

Another way to use code chunks in WordPress is to create a child theme using code snippet (s). To proceed, it would help if you created a Child Theme using code snippet(s).

Use a WordPress Plugin

Using plugins to use Code Snippets in WordPress is beginner-friendly. You’re ready to proceed once you install a plugin like Code Snippets.

The plugin provides input areas for code chunks. For example, using code areas for Headers and placing code snippets modifies Header information.

Using code snippets manually

Using code snippets manually is an advanced option.

In this scenario, if you know how to proceed, you can modify a Theme’s files, WordPress core infrastructure, or PHP source codes to place chunks. However, repeating the changes is always required, and every time WordPress, your site’s theme, or manual files are updated.

Using code chunks manually is risky, too. A syntax error can make WordPress pointless, down, or inaccessible. Be aware.

Example of Code Snippets

Let’s describe sample code snippets.

Disable Admin Bar in WordPress

Place the following Code in Functions.PHP to turn off the WordPress admin bar. Remember to save changes at the end.

// Code Snippet: Let’s hide the WordPress admin Bar

add_filter( ‘show_admin_bar’, ‘__return_false’ );

Changing WordPress Colors

To change colors in WordPress, such as paragraph or Text colors – place the following code snippet in the Advanced CSS option.

p {

color: red;

}

As you can see, the above Code changes the paragraph’s color.
