| 1029 The form variable | |
| 1030 ::::::::::::::::: | |
| 1031 | |
| 1032 The form variable is a little special because it's actually a python | |
| 1033 FieldStorage object. That means that you have two ways to access its | |
| 1034 contents. For example, to look up the CGI form value for the variable | |
| 1035 "name", use the path expression:: | |
| 1036 | |
| 1037 request/form/name/value | |
| 1038 | |
| 1039 or the python expression:: | |
| 1040 | |
| 1041 python:request.form['name'].value | |
| 1042 | |
| 1043 Note the "item" access used in the python case, and also note the explicit | |
| 1044 "value" attribute we have to access. That's because the form variables are | |
| 1045 stored as MiniFieldStorages. If there's more than one "name" value in | |
| 1046 the form, then the above will break since ``request/form/name`` is actually a | |
| 1047 *list* of MiniFieldStorages. So it's best to know beforehand what you're | |
| 1048 dealing with. | |
