I have like a contact us form, and basically what I want is for the user to click the submit button and then for this data to be stored on a remote database on a server. Problem is I don't know how to link the javascript and php stuff to the button.
This is my code:
<html>
<head>
<title>Contact Us</title>

action="contactus.php"should be in your form tag, not your button tag. – devlin carnate Commented Mar 18, 2016 at 22:25

Reset to default 2You have action on the wrong tag. Remove it from here:
<button type="button" action="contactus.php" class="btn btn-success">Submit</button>
Put it here:
<form action="contactus.php">
Also, change your button from type "button" to "submit"
<button type="submit" class="btn btn-success">Submit</button>
And this is just semantics, but perhaps an important distinction: the button is not a bootstrap button. It's an HTML button. You're styling it using bootstrap css.
Update: OP has asked how to get the "JavaScript stuff" working. Here's one way:
I like id's, so add an id to your form tag. I also like to be explicit about the form submit method, so add that to your form tag, too:
<form id="myForm" action="contactus.php" method="post">
Magical JavaScript Stuff
var form = document.forms.myForm
form.onsubmit = function() {
var forename = document.getElementById("forename").value;
var surname = document.getElementById("surname").value;
var ments = document.getElementById("ments").value;
if (forename == null || forename == "") {
alert("Forename is empty");
return false;
} else if (surname == null || surname == "") {
alert("Surname is empty");
return false;
} else if (ments == null || ments == "") {
alert("Comments is empty");
return false;
}
document.register.submit();
}
Here is a Fiddle Demo. Note: I removed the action from the form tag in the demo because it doesn't know what "contactus.php" is.
One other note: If you're only intention with the JavaScript function is to verify that the form fields have been filled out, you may be better off using the HTML input attribute required.
For example:
<input type="text" class="form-control" id="forename" placeholder="Forename" required>
Here's a Fiddle Demo showing how it works.
use method in your form POST or GET and add action with the name of php file which handles the submit. Sample code
<form action="example.php" method="post" >
<input type="text" name="user_name" placeholder="Name">
<input type="text" name="user_surname" placeholder="Surname">
<input type="email" name="user_email" placeholder="Email">
<input type="password" name="user_pass" placeholder="Password">
<input type="submit" name="submit">
</form>

and html submit here
As a beginner, I first suggest you use jQuery rather than pure javascript. For one thing, it's much less typing and (imho) far easier to master. You code in jQuery, and behind the scenes jQuery turns that into javascript at runtime.
Since you are using bootstrap, you already have the jQuery library loaded (or you are supposed to have it -- your code was missing it). Press Ctrl+U to see page code in linked example. Anyway, since it's included on the page, you might as well use it.
Your sample code, fixed:

Since you are new to jQuery, here are some free beginner-level tutorials to get you started. (It's where I learned myself, and they're free)
