Return a list containing references to field name/value pairs.
Each entry in the list has a {name} field and a {value} field. It may
have other fields as well, which caller should ignore. The
returned list should be treated as read only (must not be written to).

Object representing a single form definition.
- Package TWiki::Form

ClassMethod new ($session,$web,$form)
- $web - default web to recover form from, if $form doesn't specify a web
-
$form - topic name to read form definition from
May throw TWiki::OopsException
ObjectMethod renderForEdit ($web,$topic,$meta,$useDefaults) -> $html
-
$web the web of the topic being rendered
-
$topic the topic being rendered
-
$meta the meta data for the form
-
$useDefaults if true, will use default values from the form definition if no other value is given
Render the form fields for entry during an edit session, using data values
from $meta
ObjectMethod renderFieldForEdit ($fieldDef,$web,$topic,$value) -> $html
-
$fieldDef the field being rendered
-
$web the web of the topic being rendered
-
$topic the topic being rendered
-
$value the current value of the field
Render a single form field for entry during an edit session, using data values
from $meta. Plugins can provide a handler that extends the set of supported
types
SMELL: this should be a method on a field class
SMELL: JSCalendarContrib ought to provide a 'date' handler.
ObjectMethod renderHidden ($meta,$useDefaults) -> $html
-
$useDefaults if true, will use default values from the form definition if no other value is given
Render form fields found in the meta as hidden inputs, so they pass
through edits untouched.
ObjectMethod cgiName ($field) -> $string
Generate the 'name' of the CGI parameter used to represent a field.
ObjectMethod getFieldValuesFromQuery ($query,$metaObject,$handleMandatory) -> $metaObject
Extract new values for form fields from a query.
-
$query - the query
-
$metaObject - the meta object that is storing the form values
-
$handleMandatory - if set, will throw an OopsException? if any mandatory fields are absent from the query.
For each field, if there is a value in the query, use it.
Otherwise if there is already entry for the field in the meta, keep it.
Otherwise, if $handleMandatory, initialise the field to '' and set it in the meta.
ObjectMethod isTextMergeable ($name) -> $boolean
-
$name - name of a form field (value of the name attribute)
Returns true if the type of the named field allows it to be text-merged.
If the form does not define the field, it is assumed to be mergeable.
ObjectMethod getField ($name) -> \%row
-
$name - name of a form field (value of the name attribute)
Returns the field, or undef if the form does not define the field.
StaticMethod renderForDisplay ($templates,$meta)
-
$templates ref to templates singleton
-
$meta - meta object containing the form to be rendered
Static because we want to be able to do this without a form definition.
SMELL: Why? Is reading the form topic such a big burden? |
