I've a simple question about plugins. I want to use an external php library for a plugin that I want to use to manage custom forms in wordpress. In my experience with wordpress, I've learned that I need to submit all my forms to admin-post-php and that every form need to have a nonce to validate the post or get requests. So, if I write my own plugin that will take care to validate and submit the form data, how I can display a front-end page that is linked with the plugin? I'm not talking about the admin or options pages of a plugin. Thanks in advance for your answers.
