NAME
HTML::FormHandler::Manual::Reference - concise reference
DESCRIPTION
This is a concise reference of HTML::FormHandler.
HTML::FormHandler has a lot of options and many ways to customize your forms. More complete documentation can be found at HTML::FormHandler, HTML::FormHandler::Field, HTML::FormHandler::Model::DBIC, HTML::FormHandler::Render::Simple, and in the individual field classes.
Fields
Attributes for fields defined in your form:
name Field name. Must be the same as database column name or rel
type Field type. From a Field class: 'Text', 'Select', etc
required Field is required
required_message If this field is required, the message to display on failure
id Useful for javascript that requires unique id. Set in Field.
label Text label. Not used by FormHandler, but useful in templates
order Set the order for fields. Used by sorted_fields, templates.
widget Used by templates to decide widget usage. Set by field classes.
style Style to use for css formatting. Not used by FormHandler; for templates.
title For HTML titles. Not used by FormHandler.
value_sprintf Sprintf format to use when converting input to value
password Remove from params and do not display in forms.
disabled HTML hint to not do updates (for templates) Init: 0
readonly HTML hint to make the field readonly (for templates) Init: 0
clear Don't validate and remove from database
noupdate Don't update this field in the database
writeonly Do not call field class's "fif_value" routine.
errors Errors associated with this field
(also num_errors, clear_errors, has_errors, add_error)
label_column Select lists: column to use for labels (default: name)
active_column Select lists: which values to list
sort_column Select lists: column to use for sorting (default: label_column)
sub_form The field is made up of a sub-form (only dates at this point)
size Text & select fields. Validated for text.
minlength Text fields. Used in validation
range_start Range start for number fields
range_end Range end for number fields
unique Field should be unique in the database
unique_message If field is not unique, error message.Field attributes not set in a user form
These attributes are usually accessed in a subroutine or in a template.
init_value Initial value from the database (or see init_value_$fieldname)
value The value of your field. Initially, init_value, then from input.
input Input value from parameter or initial value from database
fif For filling in the value in a form (from input or value)
options Select lists. Sorted array of hashes, keys: "value", "label"Field subroutines to subclass in a Field class
validate Main part of Field subclasses. Generic validation that
applies to all fields of this type.
validate_field If you want to override the validation in a H::F::Field
trim_value If you don't want the default trimming
input_to_value To process the field before storing, after validation
Add your own field attributes in your custom Field classes.Miscellaneous field subroutines
set_order Sets the field's order to the value of the form's field_counter
has_input Checks 'input' attribute
fif_value Convert the field's value to a format suitable for param hash
value_changed Has the field's value changed from the init_value?
required_text Returns 'required' or 'optional' according to required flag
dump For debuggingForms
Attributes to pass to new or set in form
item_class Class of db item
item_id Primary key of db item
schema Schema of item
item DB row object
init_object For default values instead of $item
dependency Array of arrays of field names. If one name has a value, all
fields in the list are set to 'required'Form field_list attributes
fields Array (or hashref) of field definitions
required Hashref of 'required' fields
optional Hashref of non-required fields
auto_required Array of required field names (types from 'guess_field_type')
auto_optional Array of optional field namesOther Form attributes
name Form name
validated Flag that form has validated
ran_validation Flag that validation has already been run
field_name_space Where to look for your fields
num_errors Number of errors
updated_or_created 'updated' or 'created' in database
user_data Place to store user data
language handle For MakeText
field_counter For setting field order
params HTTP parameters
fields Field array
required Array of required fields
parent_field For subforms
active_column The 'active' column for all select lists in the form
html_prefix Flag to prefix html field names with the form name
submit
http_method
action
user_data
ctx
Form methods
has_field Moose-y sugar for declaring fields
clear Useful in tests
fields
sorted_fields
field( $name )
field_exists( $name )
has_error Ran_validation & !validated
error_fields
errors
error_field_names
uuid
process
update
validate( $params )
Subroutines for your form
options_$fieldname Provides a list of key value pairs for select lists
validate_$fieldname Validation routine for field
init_value_$fieldname Overrides initial value for the field
cross_validate For validation after individual fields are validated
Plus any subroutine you care to write...Methods to subclass from HTML::FormHandler::Model::DBIC
validate_model Add additional database type validation
update_model To add additional actions on update
guess_field_type To create better field type assignment for auto forms
Useful in a template
$form->has_errors [% IF form.has_errors %]
$field->has_errors [% IF field.has_errors %]
$form->error_fields [% FOREACH field IN form.error_fields %]
$form->error_field_names [% FOREACH name IN form.error_field_names %]
$form->errors Array of error messages for all fields
[% FOR field IN form.error_fields %]
[% FOR error IN field.errors %]
<p><span class='error' id=error>[% error %] </span></p>
[% END %]
[% END %]
sorted_fields [% FOREACH field IN form.sorted_fields %]
uuid subroutine that returns a uuid
$form->fif value="[% form.fif.title %]"
$field->fif value="[% field.fif %]
