Package TWiki::Form

Object representing a single form definition.

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

ObjectMethod getFieldValuesFromQuery ($query,$metaObject,$handleMandatory) -> $metaObject

• $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)

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)

StaticMethod renderForDisplay ($templates,$meta)

• $templates ref to templates singleton
• $meta - meta object containing the form to be rendered

SMELL: Why? Is reading the form topic such a big burden?
