While using the free or premium WordPress themes, most people make these common mistakes. The below-mentioned tips can help avoid these mistakes and save your time while creating themes people will love to use.
Overdoing things can kill the objective
In your effort to make things look nicer, you might create functions that will do the same things as an existing function in order to wrap things. Remember the codes you added in this way can get hard to maintain. Sometime later or when someone else looks at your code, it will be difficult to know from where the function is fetching the files from.
Never predict the future
Some developers make the mistake of inventing hypothetical scenarios that might never occur in future. One such example is displaying social icons in the middle of your post. This can lead them to develop a totally unnecessary bloat for an unpredictable future. Instead, you must only refactor your real needs and create room for them.
Premature optimization is not good for you
Though it is not always bad to optimize your codes, you must do it intelligibly. Optimizing code is necessary while saving database queries and running costly functions in the loop. Nevertheless, it is not prudent to throw everything into a variable only to save a function call.
Do not go for variables with regard to template files
While not opting for too much optimization, you will have only fewer variables in your template files. You can develop on this idea and avoid any variables in the template files at all. Instead of defining two different variables, you can extract them into functions. When a given variable is repeated all over the template files, it can give way to repetition. While used along with WordPress hooks or pluggable functions pattern, the codes will become more readable and extendable.
Since WordPress is constantly evolving, you must stay up-to-date with the best practices and questions. Also, reflect on the codex from time to time and ensure if you are still doing something that still holds good.
Depend on native WordPress functions as much as possible
When you depend mostly on the native WordPress themes, others can easily tap into your theme from a plugin or a child theme.
Do not construct your own framework
The codes you write must be clean, reusable and perform well. The mistakes that can lead to constructing your own codes include premature optimization, predicting a hypothetical future, ignoring the native WordPress functions, looking forward to saving on a few keystrokes. Many developers build solid frameworks for themselves, refactor them many times only to strip them away at some point when they turn a nuisance. The problems that are born from building a framework yourself are difficult to maintain, encroaching into the plugin territory and more complexity which will all render working with them extremely difficult.
Often many mistakes are done in order to save time in future or improve the code in some way. Know that WordPress has its own theming and coding standards. When you wish to write PHP in a custom way in your template files, it is good to adhere to the WordPress way though it might not look like the best way. This will help save a lot of hassles in future and also let you get the best out of this most wonderful platform.
