\nIn order to make this clearer, a simple example is provided. First, assume we have a
\nPDF<\/a>
\nform containing the fields volume, publisher, preparer, date, comment
\nshow_publisher, show_preparer<\/tt>.
\nThe first five fields are text input fields; the last two are check boxes.
\nOur PHP script shall always display the values of the fields volume, date,
\ncomment<\/tt>, but display the value of the fields publisher and preparer<\/tt>
\nonly if the corresponding check boxes are checked. If the boxes are checked, their
\nvalue is “On” since it was preset when the form was created. And of course the
\nform also has a submit button, in our case it even has a reset button.
\nHitting the submit button runs the following script. This script evaluates the
\nfield data as described above.<\/div>\n
