I am new to web dev with WP. I just realized that I made my front page (it has a form to be filled out by a user) by putting the code for it in a php file (through CPanel) and using <?php include() ?> to use that php file in my index.php. However, I just noticed that WP has a Pages section where I can add code by simply surrounding it with <code></code>. What is the best practice here? Am I under-using the CMS that is Wordpress by not using this Pages section? Or is it ok to not use it?
you can use some pulgins to use php code in pages like "allow-php-in-posts-and-pages" . and if you want some php file then you have create a template for that and that temmplate should be add in wp-page .
