Top 7 Mistakes To Avoid During WordPress Plugin Development Featured Image

WordPress is the first and one of the most popular choices of global giants like Sony Music, BBC America, MTV News, The New Yorker, and so many other names for the purpose of website development. WordPress is a solid CMS platform that marks the release of about more than thousands of blogs, almost every day.

However, during the task of its development, it is not a surprise to encounter mistakes. Any developer has to accept the fact that mistakes are a part of the development process because it proves your gut to risk on new ideas.

We are making a list of seven common possibilities that lands you in a troublesome situation. Let us discuss them to avoid the blunders that the developers face more often while designing WordPress tools and plugins.

Code Compatibility Missing

The compatibility of PHP and WordPress version is the foremost thing to be taken into consideration even before writing the first line of coding. It must be ensured that the designed code supports the latest updates as well as recent versions so that it is always useful.

Thus, it becomes a necessity to have a clear understanding of your potential market and compatibility before stepping into the world of plugin development.

Switching Off The Debug Mode While Development

When the debug mode is turned ‘on’, it alerts about the code errors and easily enables the task of finding warnings. After developing the WordPress plugin locally with the help of the following lines, do not forget to disable it again.

define( 'WP_DEBUG', true ); 
define( 'WP_DEBUG_LOG', true )

Most developers forget about the debugging tools of WordPress and fail, as they overlook this particular step.

Wrong Choice of Function Names

Takeaway- If your mind feeds on only using a short and simple name for the functions, it might lead your code to a poor naming convention scenario which must be avoided. Trust to prefix your functions with PHP classes and you are good to go.

Ignoring WordPress Nonces

It is quite a common mistake that most of the developers make by focusing only on the plugin functionality and not its safety. The issue can be resolved by nonce utilization in your code.

Nonces are generally, security tokens, that avoid the misuse of your URL’s and forms. Each user possesses a distinct nonce which makes the task of identifying the user’s request for a certain action, easier. Nonces are advantageous as they help to prevent SQL injections and CSRF attacks.

Not Reviewing With The Official WordPress Guidelines

If your plugin includes any amount of errors, the Review Team will send you an email to fix it and resubmit the code. If they suspect any malicious intent behind the plugin development, they won’t approve it and ban it from the WordPress repository too.

The acceptance of following these standards and guidelines not only helps in raising your probability of acceptance in the WordPress community but also enables others to expand your work and use it.

No Strategy For Wiping Off The Risk of SQL Injection

The plugin developers must agree with the experts and use the prepare() function of the WordPress core that sanitizes the SQL queries’ parameters.

No Coding

Always try to focus on maintaining clean plugin codes from the very beginning.
