/**
|
|
|
|
* Base class for all forms.
|
2012-03-24 04:38:57 +01:00
|
|
|
* The form class is an extensible base for all forms on a SilverStripe application. It can be used
|
2007-07-19 12:40:28 +02:00
|
|
|
* either by extending it, and creating processor methods on the subclass, or by creating instances
|
|
|
|
* of form whose actions are handled by the parent controller.
|
2007-09-16 03:52:35 +02:00
|
|
|
*
|
|
|
|
* In either case, if you want to get a form to do anything, it must be inextricably tied to a
|
2007-07-19 12:40:28 +02:00
|
|
|
* controller. The constructor is passed a controller and a method on that controller. This method
|
|
|
|
* should return the form object, and it shouldn't require any arguments. Parameters, if necessary,
|
|
|
|
* can be passed using the URL or get variables. These restrictions are in place so that we can
|
|
|
|
* recreate the form object upon form submission, without the use of a session, which would be too
|
|
|
|
* resource-intensive.
|
2015-06-12 00:28:32 +02:00
|
|
|
*
|
2008-10-01 20:32:10 +02:00
|
|
|
* You will need to create at least one method for processing the submission (through {@link FormAction}).
|
|
|
|
* This method will be passed two parameters: the raw request data, and the form object.
|
|
|
|
* Usually you want to save data into a {@link DataObject} by using {@link saveInto()}.
|
|
|
|
* If you want to process the submitted data in any way, please use {@link getData()} rather than
|
|
|
|
* the raw request data.
|

2009-07-07 00:06:42 +02:00
|
|
|
* <h2>Validation</h2>
|
2009-01-08 00:00:54 +01:00
|
|
|
* Each form needs some form of {@link Validator} to trigger the {@link FormField->validate()} methods for each field.
|
2012-09-26 23:34:00 +02:00
|
|
|
* You can't disable validator for security reasons, because crucial behaviour like extension checks for file uploads
|
|
|
|
* depend on it.
|
2009-01-08 00:00:54 +01:00
|
|
|
* The default validator is an instance of {@link RequiredFields}.
|
|
|
|
* If you want to enforce serverside-validation to be ignored for a specific {@link FormField},
|
|
|
|
* you need to subclass it.
|
2007-07-19 12:40:28 +02:00
|
|
|
*
|
2009-07-07 00:06:42 +02:00
|
|
|
* <h2>URL Handling</h2>
|
|
|
|
* The form class extends {@link RequestHandler}, which means it can
|
|
|
|
* be accessed directly through a URL. This can be handy for refreshing
|
|
|
|
* a form by ajax, or even just displaying a single form field.
|
|
|
|
* You can find out the base URL for your form by looking at the
|
|
|
|
* <form action="..."> value. For example, the edit form in the CMS would be located at
|
|
|
|
* "admin/EditForm". This URL will render the form without its surrounding
|
2015-06-12 00:28:32 +02:00
|
|
|
* template when called through GET instead of POST.
|
|
|
|
*
|
|
|
|
* By appending to this URL, you can render individual form elements
|
2009-07-07 00:06:42 +02:00
|
|
|
* through the {@link FormField->FieldHolder()} method.
|
|
|
|
* For example, the "URLSegment" field in a standard CMS form would be
|
|
|
|
* accessible through "admin/EditForm/field/URLSegment/FieldHolder".
|

API CHANGE: Renamed conflicting classes to have an "SS_" namespace, and renamed existing "SS" namespace to "SS_". The affected classes are: HTTPRequest, HTTPResponse, Query, Database, SSBacktrace, SSCli, SSDatetime, SSDatetimeTest, SSLog, SSLogTest, SSLogEmailWriter, SSLogErrorEmailFormatter, SSLogErrorFileFormatter, SSLogFileWriter and SSZendLog.
MINOR: Replaced usage of renamed classes with the new namespaced name.
