            </form>

your name and email inputs do not have a name attribute listed for them so will not send any data in the form submission.

you need to alter them as follows:

<input type="text" class="form-control" name="name" id="name" placeholder="Enter name" required="required" />


<input type="email" class="form-control" name="email"  id="email"  placeholder="Enter email" required="required" />

This may not be the issue that causing the error but it will cause an issue.

also it does not seem that you are opening php before your require statement. therefore the php section won't work.

You need this

<?php
require....
