See Doc/Dev/FormTypes.
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.
<?php /* Require and set up Horde_Form. */ require_once 'Horde/Form.php'; require_once 'Horde/Form/Renderer.php'; require_once 'Horde/Variables.php'; /* Set up this data as a new Horde_Form_Vars object. */ $vars = Variables::getDefaultVariables(); if (!$vars->exists('example_foo')) { $vars->set('example_foo', 'Foo Sample Data'); } /* Get formname var to check if submitted later on. */ $formname = $vars->getVar('formname'); /* Get the form object, setting the vars and the title. */ $myform = new Horde_Form($vars, _("An Example Form"), 'some_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) { if ($myform->validate($vars)) { $myform->getInfo($vars, $info); /* Do something with this form data. */ echo 'saving data<br />'; } } /* Render out the form. */ $myform->renderActive(new Horde_Form_Renderer(), $vars, 'edit.php', 'post');
Here's an example that uses the conditional_enable action to enable a text description if the user picks "Other".
<?php /** * Example for the conditional_enable action. */ @define('HORDE_BASE', dirname(__FILE__)); require_once HORDE_BASE . '/lib/core.php'; require_once 'Horde/Form.php'; require_once 'Horde/Form/Action.php'; require_once 'Horde/Form/Renderer.php'; require_once 'Horde/Variables.php'; $registry = &Registry::singleton(); $vars = Variables::getDefaultVariables(); $form = new Horde_Form($vars, 'Using conditional enable'); $choices = array('big' => 'BIG', 'small' => 'small', 'other' => 'Other'); $form->addVariable('Select something', 'choices', 'enum', true, false, '', array($choices, true)); $o = &$form->addVariable('If other, please describe', 'other_text', 'text', false, false); $params = array('target' => 'choices', 'enabled' => true, 'values' => array('other')); $o->setAction(Horde_Form_Action::factory('conditional_enable', $params)); /* Render the form. */ $form->renderActive(new Horde_Form_Renderer(), $vars, 'form.php', 'post');
<?php require_once 'Horde/Form.php'; require_once 'Horde/Variables.php'; require_once 'Horde/Form/Renderer.php'; $vars = Variables::getDefaultVariables(); /* Set up the form object. */ $form = new Horde_Form($vars, 'A simple form'); $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)); if ($form->validate($vars)) { $form->getInfo($vars, $info); echo 'You have submitted:<br /><pre>'; var_dump($info); echo '</pre>'; } /* Render the form. */ $form->renderActive(new Horde_Form_Renderer(), $vars, 'simple_form.php', 'post');
<?php require_once 'Horde/Form.php'; require_once 'Horde/Form/Renderer.php'; require_once 'Horde/Variables.php'; class TestForm1 extends Horde_Form { var $_useFormToken = false; function TestForm1(&$vars) { parent::Horde_Form($vars, _("Step 1")); $enum = array('' => _("Select:"), 1 => _("Yes"), 0 => _("No")); /* addVariable( Visible Text, name, type, required, readonly, * description, params) */ $this->addVariable(_("Enum"), 'opciones', 'enum', true, false, _("Simple description"), array($enum)); $this->addVariable(_("Boolean"), 'bool', 'boolean', false, false ); $this->addVariable(_("Integer"), 'number', 'int', true, false ); $this->addVariable(_("A Date"), 'mybday', 'date', false, false ); } } class TestForm2 extends Horde_Form { var $_useFormToken = false; function TestForm2(&$vars) { parent::Horde_Form($vars, _("Step 2")); $this->addVariable(_("Email"), 'email_address', 'email', true, false ); } } $r = new Horde_Form_Renderer(); $vars = Variables::getDefaultVariables(); $form1 = new TestForm1($vars); $form2 = new TestForm2($vars); $form1Valid = $form1->validate($vars, true); $form2Valid = $form2->validate($vars); /* Check if one form is not valid. */ if (!$form1Valid || !$form2Valid) { if ($form1Valid) { $form2->open($r, $vars, 'form.php', 'post'); // preserve form1 variables $form1->preserve($vars); $r->beginInactive($form1->getTitle()); $r->renderFormInactive($form1, $vars); $r->end(); // now render the active form $r->beginActive($form2->getTitle); $r->renderFormActive($form2, $vars); $r->submit(); $r->end(); $form2->close($r); } else { $form1->open($r, $vars, 'form.php', 'post'); $r->beginActive($form1->getTitle()); $r->renderFormActive($form1, $vars); $r->submit(); $r->end(); $form1->close($r); } } else { $form1->getInfo($vars, $info); $form2->getInfo($vars, $info); echo '<pre>'; print_r($info); echo '</pre>'; }
