1606 The form variable is a bit special because it's actually a python |
| 1142 | 1607 FieldStorage object. That means that you have two ways to access its |
| 1608 contents. For example, to look up the CGI form value for the variable | |
| 1609 "name", use the path expression:: | |
| 1610 | |
| 1611 request/form/name/value | |
| 1612 | |
| 1613 or the python expression:: | |
| 1614 | |
| 1615 python:request.form['name'].value | |
