I'd just like to start by saying this isn't a homework assignment. I'm building a webpage for this business my brother and I are starting. I have a part of the website where people can submit a request. My PHP script works, but the problem is, people can submit a blank request, which in turn gets emailed to us all blank. So I want to make it so that their email address is required, but I can't figure out how. Below is the FORM section of my HTML. If anyone can help, i'd seriously appreciate it. I'm sure it's something very easy, but i've been searching for two days on the internet, and nothing I'm finding seems to work. Thanks!!!! <form action="parts_request.php" method="post"> <h3>Submit a parts request</h3> Year:<br> <input type="text" name="year" size="20"> <br> Part:<br> <input type="text" name="part" size="20"> <br> Description: <br> <textarea name="description" rows="5" cols="64"></textarea> <br> Your Email: <br> <input type="text" name="email" size="25"> <br><br> <input type="submit" value="Send"> <input type="reset" value="Reset"> </form> Yea I know it's not the best, like the year field shouldn't be allowed to have 20 characters, i'm working on the small things. Email address being required is one of them. Thanks again.
