This is my bootstrap contact form code which is simple and works fine but when i try to use it for wordpress am getting error i tried many things by changing action field .can anyone tell me what real modification i have to do with this contactfrm so this works fine in wordpress.pleasse share the solution

Error: i dont know what possible changes i have to make and how to link those pages in php and where to place the php code.i tried placing contactprocess code in cotact.php before get_header(); and in action i added (action="php the_permalink(); ") . in that its displaying message at the top (Thank you for getting in touch..! We will get back you as soon as we review your message.) without submitting form.and when i try to submit the form it direct to the same link which is domianname/contact/ with home page content and getting mail without content
