  • php email form - min. characters required?

    I am using the well-known sendit.php file to email an online form. My goal is to obtain a person's full name. This form is used by existing clients and I would like to prevent them from entering initials in the name fields. I am aware nothing can prevent a client from typing random characters but thought setting a minimum of characters would persuade them to fill it out accurately.

    I have already set the first and last name fields as "required." Now I want to ensure that more than 3 characters are entered by the viewer. Any tips on how to do this?

    Thanks in advance!

    I am not sure how to do this... but not sure you would want to.
    I actually know people whose legal name is only two letters... might be frustrating for them if they can't enter their name...

      I've never heard of sendit.php, but you know how to work with PHP you can use the strlen() function to check the length of a given string:

      PHP Code:
      $fname strlen($_POST['fname']);

      if (
      $fname 4)
      //Code telling PHP what to do if the first name is less than 4 characters...

      I agree with Audentia that someone named Al or Sue would probably be very frustrated at not being able to enter their name (I have a friend whose legal name is Kim).

      The world is divided into people who think they are right.

        empty() is a more user friendly option. I wouldn't recommend a minimum length because as others have said it is possible to have a 2 or 3 character name. I don't think it would be bad though to check for more then 1 using strlen().

            I work with someone whose last name is Ng. He'd be unable to fill out your form properly.

              Lots of people wouldn't be able to use it.
