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.
This tutorial focuses on the process of sending a form to a Web server. 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. Any field may be both used for data entry and later populated by new data after submission to the Web server. To accomplish this, the CGI script must send data back as a FDF file.
