Depending Upon what it's developed to do, a plugin can be composed of a solitary PHP documents or numerous documents. The major PHP documents, which is the matching of index.php as well as index.html for WordPress styles as well as HTML styles, is one of the most essential documents.

It's advised that designers of WordPress call their major plugin documents by the convention after their plugin. The major plugin declare a plugin called WP WordReplace plugin, as an example, would certainly be wp-wordreplace. php Usage just hyphens (-) in between words rather than highlights (_) when including a separator to your name.

Summary: This plugin changes words with your chosen words.
Variation: 1.0.

Each specification in the above header is obvious, so I'm not mosting likely to enter into the information. Simply ensure that when creating your Plugin as well as Writer URIs, or the web links will certainly not function, you consist of the pertinent http:// or https://.

If you make use of a GPL2 certificate or a permit suitable with GPL2, follow your header with the complying with certificate details:
