|You kinda need to be more specific. But if you are asking what I am assuming: you have a form that you want sent to your email when submitted?|
Again, I am assuming the form is already created.
Using the syntax from W3 Schools you would place your form variables (ie $password) into the body section.
Remember that the body section of an email supports HTML, therefore you can format the form data as you would like similar to how you would style a web page.
