This tag says simply, "when visitor presses submit button, send all of data that was entered to senddata.php file". The senddata.php file contains special code which performs necessary magic to send data to you.

Now you need to include some special "hidden" values to tell forms processor what to do. Hidden values do not cause any entry to be done - they merely set up data to be used by forms processing routine.

These two lines inform Bravenet processor of user number of form. This is created when you create a new form. Each form has it's own unique number. Other forms processing systems may use similar identifiers, or they may do something completely different.

It's important to understand this concept - these values are completely defined by forms processing routine. Different names and values will be used by different forms systems.

Once you have set up required and optional hidden values for your forms processor, you need to define form fields and input values. The three lines below show how to do this.

What is your name?

Where are you from?

E-mail address?

These three lines ask your visitors for their name, location and email address. As you can see, prompts and formatting are included directly in your form. The tags are used to define fields that actually get data. The word "size" is used to indicate how many characters to retrieve.

Now it's time to give your visitors a way to submit form.

These two lines define "submit" and "reset" buttons. The reset button is optional, but submit button is required (otherwise how would data actually get sent to form?)

Now you need to end form. This is done as shown below.
