Lets take a look at all the steps
From Start to Finish Guidance
1. Make A Productive Strategy:
It is vital to ideally strategize the creation process since it helps you primarily handle the code according to the plugin's complexity. If your plugin has little association with WordPress' Core Data, less work is needed unless you foresee it growing substantially later. Conversely, comprehensive plugins with more groupable code support the classes, different style sheets, and the active code organization's script files. It definitely will credit you with plugin maintenance for a more extended period. This stage calls for a significant time.
2. Use Namespacing For WordPress Plugin:
All your files, functions, classes, and variables are required to be namespaced (prefixed) with your plugin name. Note that your plugin's functions are implemented in the global namespace with other non-namespace functions, which means it possibly clashes with the same function somewhere else. The best option to fix this problem is to make a class for your plugin, so that all methods will be namespaced under the class name, and even better, you can even now add notable names to the function like this:
3. Take Security Measures:
Many developers relegate protection as an afterthought status and end up making a mistake. Make sure your WordPress plugin is safe. WordPress ensures safety by providing an apprentice function, sanitize *() class of support functions to not allow attacks to infringe your website's protection. This feature is perfect and ensures that user inputs are thoroughly sanitized before moving to the database. Data sanitizing is important when dealing with the user entry or exposing your site to XSS (Cross-Site Scripting) and other harmful consequences. The following are some sanitize inputs and escape outputs that we’ve highlighted for you:
- ü esc_url_raw
- ü esc_url
- ü esc_textarea
- ü esc_html
- ü esc_attr
- ü wp_filter_kses
4. White Screen Death:
When a public user accesses your .php files directly via URL, you must always make White Screen Death, shortly known as WSoD, a must. Want to know why? Since it may eventually activate and lead to unpredictable actions if your file includes any I / O operations. You can prevent your vital files from being accessed (directly), ensuring that plugin directories and data are only run within the WordPress setting.
5. Extendable Plugin Development Method:
You have to follow a strategy of extendable plugin development if you periodically come up with an issue of modifying the plugin but can't seem to find any other means aside by cracking the source code? To ensure that your WordPress plugin is up to par, you can have action/filter hooks to enable other people to expand plugins' functionality according to their ability.
6. Implementation Of Ajax:
AJAX's implementation is advantageous if you want to be versatile enough to use the core WordPress CMS. Ajax is a flexible tool that helps developers to create more efficient and streamlined applications. It's not built-in support for WordPress workflow, but an amalgamation of numerous programming languages.
7. Do Not Overload:
Do not frivolously flood your plugin with code that is better called elsewhere. Your web pages and sections should load global stylesheets, html, and other files that apply across the site. If there is ever an opportunity to avoid duplicate code, those files are the ones to first look into calling for your plugin.
8. Internationalization:
Since WordPress is used globally, it's best to develop a WordPress plugin that translates easily to any language. Internationalization does not require us to provide the translations (although the multi-lingual one among us can do so quickly), only for the potential translators to take the appropriate steps. This isn't a necessary step to do, but it is always vital to reach the broadest possible audience.
