If the form contains non-ASCII characters, use the encoding keyword parameter set to the value of the encoding defined for the document. This reads the form contents from the standard input or the environment depending on the value of various environment variables set according to the CGI standard. Since it may consume standard input, it should be instantiated only once.
The FieldStorage instance can be indexed like a Python dictionary. It allows membership testing with the in operator, and also supports the standard dictionary method keys and the built-in function len. For instance, the following code which assumes that the Content-Type header and blank line have already been printed checks that the fields name and addr are both set to a non-empty string:.
Here the fields, accessed through form[key] , are themselves instances of FieldStorage or MiniFieldStorage , depending on the form encoding. The value attribute of the instance yields the string value of the field. The getvalue method returns this string value directly; it also accepts an optional second argument as a default to return if the requested key is not present. If the submitted form data contains more than one field with the same name, the object retrieved by form[key] is not a FieldStorage or MiniFieldStorage instance but a list of such instances.
Similarly, in this situation, form. If you expect this possibility when your HTML form contains multiple fields with the same name , use the getlist method, which always returns a list of values so that you do not need to special-case the single item case. For example, this code concatenates any number of username fields, separated by commas:. If a field represents an uploaded file, accessing the value via the value attribute or the getvalue method reads the entire file in memory as bytes.
This may not be what you want. You can test for an uploaded file by testing either the filename attribute or the file attribute. You can then read the data from the file attribute before it is automatically closed as part of the garbage collection of the FieldStorage instance the read and readline methods will return bytes :.
FieldStorage objects also support being used in a with statement, which will automatically close them when done. If an error is encountered when obtaining the contents of an uploaded file for example, when the user interrupts the form submission by clicking on a Back or Cancel button the done attribute of the object for the field will be set to the value When this occurs, the item will be a dictionary-like FieldStorage item.
In this case, it can be iterated over recursively just like the top-level form object. In this case, the list , file , and filename attributes are always None.
Changed in version 3. This section describes a higher level interface which was added to this class to allow one to do it in a more readable and intuitive way.
