There are total fourteen field in my code. All are text and numeric fields.Below code is the form validation code using php. I have checked where each field is empty, or wrongly filled(invalid data). But it is not validating the form. After clicking on submit button an empty page is appearing but the url i.e.,http://localhost/index.php remains same. I am unable to find any error. Please help me. I am new to coding.My code is a bit longer.
