Okay just trying to keep with the same thread. Has anyone used this
helper? Is this something included now in the Cake core?

Subject: Select tag with optgroup
To: Cake PHP
Hi i would like to share with you a helper function to print a select
tag with optgroups.
Actually it's just a small mod the the existing selecttag function.
To have optgroups, make the $optionElements parameter a two dimensional
array. With the key for the sub array the name of the subgroup.. for
example
array(
'Fruits' => array(
'banana' => 'Bananas',
'apl' => 'Apples'
),
'Animals' => array(
'horse' => 'Horse',
'donley' => 'Donkey'
),
'car'=>'Car'
)
Note that car in the example will be outputed as a regular option
element..
Here's the helper.
class MorehtmlHelper extends Helper {
var $helpers = array('Html');
/**
* Returns a SELECT element,
*
* @param string $fieldName Name attribute of the SELECT
* @param array $optionElements Array of the OPTION elements (as
'value'=>'Text' pairs) to be used in the SELECT element. Can be a
2dimensional array.
* @param boolean $show_empty Show/hide the empty select option
* @param array $selectAttr Array of HTML options for the opening
SELECT element
* @param array $optionAttr Array of HTML options for the enclosed
OPTION elements
* @return string Formatted SELECT element
*/
function selectOptTag($fieldName, $optionElements, $selected=null,
$selectAttr=null, $optionAttr=null, $showEmpty=true)
{
$this->Html->setFormTag($fieldName);
if ($this->Html->tagIsInvalid($this->Html->model,
$this->Html->field))
{
if (isset($selectAttr['class']) &&
trim($selectAttr['class']) != "")
{
$selectAttr['class'] .= ' form_error';
}
else
{
$selectAttr['class'] = 'form_error';
}
}
// do not display the select tag if no option elements are
avaible
if (!is_array($optionElements) || count($optionElements) == 0)
{
return null;
}
if(!isset($selected))
{
$selected = $this->Html->tagValue($fieldName);
}
if( isset($selectAttr) && array_key_exists( "multiple",
$selectAttr) )
{
$select[] =
sprintf($this->Html->tags['selectmultiplestart'], $this->Html->model,
$this->Html->field, $this->Html->parseHtmlOptions($selectAttr));
}
else
{
$select[] = sprintf($this->Html->tags['selectstart'],
$this->Html->model, $this->Html->field,
$this->Html->parseHtmlOptions($selectAttr));
}
if($showEmpty == true)
{
$select[] = sprintf($this->Html->tags['selectempty'],
$this->Html->parseHtmlOptions($optionAttr));
}
foreach ($optionElements as $name => $title)
{
if (is_array($title)) {
$select[] = '<optgrouplabel="'.$name.'">';
foreach ($title as $subname => $subtitle)
{
$optionsHere = $optionAttr;
if (($selected !== null) && ($selected ==
$subname))
{
$optionsHere['selected'] = 'selected';
} else if ( is_array($selected) &&
array_key_exists($subname, $selected) )
{
$optionsHere['selected'] = 'selected';
}
$select[] =
sprintf($this->Html->tags['selectoption'],
$subname, $this->Html->parseHtmlOptions($optionsHere), $subtitle);
}
$select[] = '</optgroup>';
}
else {
$optionsHere = $optionAttr;
if (($selected !== null) && ($selected == $name))
{
$optionsHere['selected'] = 'selected';
} else if ( is_array($selected) &&
array_key_exists($name,
$selected) )
{
$optionsHere['selected'] = 'selected';
}
$select[] =
sprintf($this->Html->tags['selectoption'],
$name, $this->Html->parseHtmlOptions($optionsHere), $title);
}
}
$select[] = sprintf($this->Html->tags['selectend']);
return implode("\n", $select);
}
}
