How to make my next button to submit form?

Question

I am creating a student information form in html as in the image:

My next button is an image and the code for it is as follows:

<input type="image" id="registersubmit6" name="registersubmit6" src="images/arrow-right.png"  title="finish" onclick=""/>

When user clicks on next button, I want to submit this form and move to next page.How I can do both at the moment?

Should I use javascript or PHP? and if yes then how?

Answer 1

<input type="image" id="registersubmit6" name="registersubmit6" src="images/arrow-right.png"  title="finish" onclick="submitForm()"/>
function submitForm(){
document.getElementById('id of your form').submit();
}
