Chapter 15: Still More Forms

Hidden Fields

Yet another type of input is HIDDEN input.

<INPUT TYPE=HIDDEN NAME="FORMNAME" VALUE="Company Position Form 1">

A HIDDEN input is a name/value pair that is returned to you but does not show up anywhere on the web page. The hidden input above is needed for use with Mailto Formatter.

Let's suppose you were a company trying to generate leads for a new product. You have a standard form for gathering information... name, company, phone, products interested in, etc. The only problem is there are 6 slightly different versions of the form in 6 slightly different places. You need to know what's coming from where. What to do?

You could add a HIDDEN input to your forms like this:

<INPUT TYPE=HIDDEN NAME="FORMNAME" VALUE="Version 1">...for the first version.

<INPUT TYPE=HIDDEN NAME="FORMNAME" VALUE="Version 2">...for the second version.

<INPUT TYPE=HIDDEN NAME="FORMNAME" VALUE="Version 3">...for the third version.

It doesn't matter what the name/value pair in the hidden input is (or any input.) "FORMNAME" is used because it saves typing. This would be a perfectly legitimate HIDDEN input:

<INPUT TYPE=HIDDEN NAME="E" VALUE="Mc^2"> ...You would get back E=Mc^2

HIDDEN inputs are also useful for cgi scripts. For example, many Internet service providers have a script you can have your forms sent to. It then gives the form back to you ready for human consumption. The hidden input tells the cgi script who you are, where to send the parsed data, etc.



Submit and Reset Buttons

Last on the list are the SUBMIT and RESET buttons:

<INPUT TYPE=SUBMIT>



SUBMIT sends the data.


RESET clears the form.

<INPUT TYPE=RESET>




We can easily change what the buttons say.

<INPUT TYPE=SUBMIT VALUE="Send it away away"><BR>

<INPUT TYPE=RESET VALUE="Clear the form"><P>





The SUBMIT button can also have a NAME. You would need this if you had more than one SUBMIT button.


Next we must tell the browser where to send the data we gather and how to send it. There are two basic things you can do:

1) You can send the data to a cgi script for processing

2) You can have the data emailed to you

As for the first, whoever wrote the script can tell you how the data should be sent.

The second, or mailto form should have the following attributes in the <FORM> tag.
Note - Microsoft's Internet Explorer 3.0 does not support mailto forms. When you try to submit the information, the new mail message window pops up. Explorer does however support forms sent to a CGI script.

<FORM METHOD=POST ACTION="mailto:xxx@xxx.xxx" ENCTYPE="application/x-www-form-urlencoded">

This line is very important. The only thing you have to do is plug in your email address after mailto: The rest must be written exactly as shown. The words FORM, METHOD, POST & ACTION do not have to be capitalized but there must be a space between each attribute - between FORM & METHOD, between POST & ACTION, and between .com & ENCTYPE.

Unfortunately the data will be sent to you in this 'only useful to a computer' format:

FORMNAME=New+Entrant&NAME=R.U.+Havinfun&ADDRESS=1313+Mockingbird+Lane
&CITY=Beverly+Hills&STATE=CA

What you'll need is a program to turn it into 'useful to a human' format:

FORMNAME=New Entrant
NAME=R.U. Havinfun
ADDRESS=1313 Mockingbird Lane
CITY=Beverly Hills
STATE=CA

Mailto Formatter (1.3MB, Win 95) is an excellent utility that does this job quite nicely.

Some mail programs are capable of converting the data without resorting to a separate program. You may want to try this method first. Just remove the instruction ENCTYPE="application/x-www-form-urlencoded" and in its place use ENCTYPE="text/plain".

When you put a mailto form on your page and someone sends you information, you'll notice that it is sent with a default Subject. If your visitor was using Netscape you'd get the default Subject "Form posted from Mozilla". Other browsers might send "Form Response", etc.

You can change this by editing what's in the <FORM> tag as follows:

<FORM METHOD=POST ACTION="mailto:xxx@xxx.xxx?subject=Company feedback form" ENCTYPE="application/x-www-form-urlencoded">


Your Own HTML Page

Open the page "feedback.html" and add the following: (the red text is what to add)

<html>
<body background="bgnd.gif">

<center><h1>Feedback Form</h1></center>
<br>
<form method=post action="mailto:YOUREMAILADDRESS?subject=Feedback" enctype="text/plain">
<b>My name is: </b><input type=text name="name">
