I'm trying to validate user input in php. This code will check if the values are null or not. If it is null, this will require the user to input the values that are null. When all the text boxes in the html form that came before this. This code will show the submit button, and that submit button will save the inputted data into the mysql database. But the problem is that the value that is saved is zero zero and zero, what might be the cause
of this?
