NAME

       Embperl::Form - Embperl Form class

SYNOPSIS

DESCRIPTION

METHODS

   new ($controls, $options)
       •   $controls

           Array ref with controls which should be displayed inside the form. Each control needs
           either to be a hashref with all parameters for the control or a control object.

           If hash refs are given it's necessary to specify the "type" parameter, to let
           Embperl::Form know which control to create.

           See Embperl::Form::Control and Embperl::Form::Control::* for a list of available
           parameters.

       •   $options

           Hash ref which can take the following parameters:

           •   formname

               Will be used as name and id attribute of the form. If you have more then one form
               on a page it's necessary to have different form names to make form validation work
               correctly.

           •   masks

               Contains a hash ref which can specify a set of masks for the controls. A mask is a
               set of parameter which overwrite the setting of a control. You can specify a mask
               for a control name (key is name), for a control type (key is *type) or for all
               controls (key is *).

               Example:

                   {
                   'info'      => { readonly => 1},
                   '*textarea' => { cols => 80 },
                   '*'         => { labelclass => 'myclass', labelnowrap => 1}
                   }

               This will force the control with the name "info" to be readonly, it will force all
               "textarea" controls to have 80 columns and it will force the label of all controls
               to have a class of myclass and not to wrap the text.

           •   defaults

               Contains a hash ref which can specify a set of defaults for the controls. You can
               specify a default for a control name (key is name), for a control type (key is
               *type) or for all controls (key is *).

               Example:

                   {
                   'info'      => { readonly => 1},
                   '*textarea' => { cols => 80 },
                   '*'         => { labelclass => 'myclass', labelnowrap => 1}
                   }

               This will make the control with the name "info" to default to be readonly, it will
               default all "textarea" controls to have 80 columns and it will set the default
               class for the labels of all controls to myclass and not to wrap the text.

           •   language

               Language setting is used for Embperl::Form::Validate, e.g. 'en' or 'de'

           •   charset

               Charset setting is used for Embperl::Form::Validate, e.g. 'utf-8'

           •   valign

               valign for control cells. Defaults to 'top' .

           •   jsnamespace

               Give the JavaScript Namespace. This allows one to load js files in a top frame or
               different frame, which will speed up page loading, because the browser does not
               need to reload the js code on every load.

               Example:

                   jsnamespace => 'top'

           •   classdiv

               Gives the CSS class of the DIV arround the form. Default cTableDiv.

           •   checkitems

               If set to true, allow to call the function diff_checkitems after the data is
               posted and see which form fields are changed.

           •   control_packages

               Arrayref with package names to search for form controls. Alternativly you can
               overwrite the method get_control_packages.

           •   datasrc_packages

               Arrayref with package names to search for form data source modules. Alternativly
               you can overwrite the method get_datasrc_packages.
