When a user types in the text box, symbols, rather than the characters appear. The form submits the entered text, not the symbols. A text field is a single line long. This allows the user to enter more than one line of text. If the number of text lines is greater than the size of the form field, the user can scroll through the text field.
Text automatically wraps according to the dimensions of the text field.
Submitting the form data. This tutorial focuses on the process of sending a form to a Web server. See RFC 1866 for more information on this data type. Some or all of a PDF form fields may be submitted. This allows a PDF form to have some fields for user the user to enter data, and others for feedback.
