Embperl::Form - Embperl Form class

* $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 deafult 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.

* valign

valign for control cells. Defaults to 'top' .

* jsnamespace

Give the JavaScript Namespace. This allows 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.
