You can do it with php or javascript but it is not safe as some visitors surfing with js-disabled browsers. Check this <URL SNIPPED>free php contact form with field validation and captcha
Where's your code? Show us what you've got so far.
Use a simple javascript function to do this.
and you just need to invoke a method in event 'onsubmit' in form tag
While calling check whether any field is null or not
if 'null' then the function should return false
otherwise true.
also you can set focus to the null field to make it more user friendly.

It is it's code

return false;
return true;
}
</script>
</head>
