Chapter: jForms: automatic forms
| « Classic forms | ^ Jelix components | jDb : database access » |
jForms is a form system which facilitate the creating of forms. Forms are described in an XML file, and an API with template-plugins allow you automatically:
- to generate the HTML form,
- to generate javascript validation script,
- to validate input with verbose error-reporting,
- to display labels in an accessible manner,
- to display the form in a flexible manner,
- managing several instances of a form at the same time - allowing to edit several records at the same time,
- initializing a form from one or several DAO's data (with inputs, listbox, radios etc …),
- save data inputed in DAOs,
- save uploaded files.
And, in the future :
- support other types of forms (with ajax, XUL, XForms etc …) using other template-plugins,
- native captcha-fields support,
- native WYSIWYG fields,
- etc …
jForms includes three distinct parts :
- XML files describing the forms,
- server-side API to manage a form and it's data,
- template-plugins to display an instance of a form.
jForms generates an object (deriving from jFormsBase) from the XML description, allowing to initialize the form's contents, and to save it etc …
The object contains all the input in it's properties.
The jForms object is also used by template-plugins to display the appropriate HTML elements.
