Option list examples.
Option list examplesMultiple, single and text input elements have option lists. Here are some more detailed examples.
<?php
/*
* Load the library...
*/
require_once '../../HtmlForm.php';
/*
* Create the example form 'listsExampleForm'
*/
/*
* Multiple input element with checkbox skin, set required
*
* Contrary to HTML5 specs, a required multiple-checkbox only needs one item
* checked to be valid.
*/
$form->addMultiple('multipleCheckbox', array(
'required' => true,
'label' => 'Multiple-checkbox',
'list' => array(
'option one' => 'label one',
'option two' => 'label two',
'option three' => 'label three',
),
));
/*
* Non-associative lists arrays
*
* The list parameter can also be a normal array (it doesn't have to be
* associative). In that case it returns the array key ("0", "1", "2"). This
* works for every element with an option list ie. text, single and multiple.
*/
$form->addMultiple('multipleSelect', array(
'label' => 'Multiple-select',
'skin' => 'select',
'list' => array(
'label one',
'label two',
'label three',
),
));
/*
* Single input element with radio-skin, set required
*
* Single is basically the same as multiple. Instead of checkboxes
* you'll get radiobuttons, so you can only select on item.
*/
$form->addSingle('singleCheckbox', array(
'required' => true,
'label' => 'Single-radiobutton',
'list' => array(
'option one' => 'label one',
'option two' => 'label two',
'option three' => 'label three',
),
));
/*
* Single with select skin
*
* The single-element rendered as a select-list instead of radion-buttons
*/
$form->addSingle('singleSelect', array(
'label' => 'Single-select',
'skin' => 'select',
'list' => array(
'label one',
'label two',
'label three',
),
));
/*
* Optgroups
*
* 'select'-skin elements support optgroups. To use them simply add another
* array dimension. This works for single and multiple elements with the
* 'select' skin.
*/
$form->addSingle('optgroupSingle', array(
'label' => 'Optgroup-single',
'skin' => 'select',
'list' => array(
'group one' => array(
'option one' => 'label one',
'option two' => 'label two',
'option three' => 'label three',
),
'group two' => array(
'option four' => 'label four',
'option five' => 'label five',
),
),
));
/*
* Datalists
*
* Modern browsers support datalists for text fields as input examples. Usage
* is similar to single or multiple element lists.
* Associative arrays (option => label) also work.
*/
$form->addText('datalistText', array(
'label' => 'Text with datalist',
'list' => array(
'option one',
'option two',
'option three',
),
));
$form->process();
if ($form->validate()) {
/*
* Success, do something useful with the data and clear the session.
*/
echo('<a href="">back</a>');
echo('<pre>');
var_dump($form->getValues());
echo('</pre>');
$form->clearSession();
