Horde_Form

Filling a form with values

The following code could be used to fill a form through Horde_Form, for example to edit a record. The example is a bit abstracted from reality, in that you would also need to build some validation around this code, checking for a form submission, etc. to eventually have a useable form.


/* Require and set up Horde_Form. */

require_once HORDE_LIBS . 'Horde/Form.php';

require_once HORDE_LIBS . 'Horde/Form/Renderer.php';

/* Get the data to be inserted, obviously with keys corresponding

   to the available fields in the form. */

$somedata = array(.....);

/* Set up this data as a new Horde_Form_Vars object. */

$vars = &new Horde_Form_Vars($somedata);

/* Get formname var to check if submitted later on. */

$formname = $vars->getVar('formname');

/* Get the form object, setting the vars and the title. */

$myform = &Horde_Form::singleton('SomeForm', $vars, _("An Example Form"));

/* Set up the form fields. */

$myform->addHidden('', 'example_hidden', 'int', false);

$myform->addVariable(_("Foo field"), 'example_foo', 'text', true);

$myform->addVariable(_("Bar field"), 'example_bar', 'longtext', true, false, _("You have to fill in some long text here"), array(4, 40));

/* Check if form submitted and validate. */

if ($formname) {

    $myform->validate($vars);

    if ($myform->isValid()) {

        $myform->getInfo($vars, $info);

        /* Do something with this form data. */

        $result = $someclass->saveMyFormData($info);

        if (is_a($result, 'PEAR_Error')) {

            $notification->push(sprintf(_("Could not create save data."), $result->message), 'horde.error');

        } else {

            $notification->push(_("Data saved."), 'horde.success');

            $url = Horde::applicationUrl('somescript.php', true);

            header('Location: ' . $url);

            exit;

        }

    }

}

/* Render out the form and it should have the fields filled in

   according to the $somedata array values. */

$renderer = &new Horde_Form_Renderer();

$myform->renderActive($renderer, $vars, 'edit.php', 'post');

$form->setButtons('Submit this form', true);

$form->addVariable('Insert some text', 'some_text', 'text', false, false, 'Insert in this box some text');

$choices = array('big' => 'BIG',

                 'small' => 'small',

                 'mixed' => 'mIxED');

$form->addVariable('Select something', 'choices', 'enum', true, false, 'Use the selection box to make your choice', array($choices,

true));
