I´m developing an application using Zend Framework 2 and I´m using two select multiple boxes. The first is populated with data from the data base, the second is empty.
I intend to set the disabled attribute as "disabled" in the first option of both selects. This way the first options will be unusable and un-clickable. Therefor a user will not be able to pass those first options from one select to the other while using the add/remove buttons.
Select 1
<select id="AttributesId" multiple="multiple" size="7" title="Select an Attribute" name="idAttributes[]">
<option value="0">Please Select an Attribute</option>
<option value="1"> Attribute 1</option>
<option value="2"> Attribute 2</option>
</select>
Select 2
<select id="SelectedAttributesId" multiple="multiple" size="7" title="Selected Attributes" name="selectedAttributes[]">
<option value="0">Current Selection</option>
</select>
The php code that generates both selects on ZF2 is:
(...)
public function __construct ($em = null)
{
parent::__construct("typeset");
$this->setAttribute("method", "post")
->setAttribute("class", "contact-form");
if(null !== $em)
{
$this->setEntityManager($em);
}
$em = $this->getEntityManager();
$query = $em->createQuery("SELECT a.idAttribute, a.internalName FROM ProductCatalog\Entity\Attribute\Attribute a ORDER BY a.internalName ASC");
$attributes = $query->getResult();
$select = new Element\Select('idAttributes');
$select->setAttribute('title', 'Select an Attribute')
->setAttribute('size', 7)
->setAttribute('multiple', 'multiple')
->setAttribute('id', 'AttributesId');
$selected = new Element\Select('selectedAttributes');
$selected->setAttribute('title', 'Selected Attributes')
->setAttribute('size', 7)
->setAttribute('multiple', 'multiple')
->setAttribute('id', 'SelectedAttributesId');
$labelIdAttributes = 'Attributes List: ';
$labelSelectedAttributes = 'Selected Attributes List: ';
$options[0] = 'Please Select an Attribute';
// this followin line doesn´t work but you can get an idea of what I need with it //$options[0]->setAttribute('deselect', 'deselect');
foreach ($attributes as $key => $value)
{
$options[$value['idAttribute']] = $value['internalName'];
}
$selectedOptions[0] = 'Current Selection';
$select->setLabel($labelIdAttributes)
->setValueOptions($options);
$selected->setLabel($labelSelectedAttributes)
->setValueOptions($selectedOptions);
$this->add($select);
$this->add($selected);
(...)
