select() public ¶

select( string $fieldName , array $options = array() , array $attributes = array() )

Returns a formatted SELECT element.

Attributes:

showParents - If included in the array and set to true, an additional option element will be added for the parent of each option group. You can set an option with the same name and it's key will be used for the value of the option.
multiple - show a multiple select box. If set to 'checkbox' multiple checkboxes will be created instead.

disabled - Control the disabled attribute. When creating a select box, set to true to disable the select box. When creating checkboxes, true will disable all checkboxes. You can also set disabled to a list of values you want to disable when creating checkboxes.

Using options

A simple array will create normal options:

$options = array(1 => 'one', 2 => 'two);
$this->Form->select('Model.field', $options));

While a nested options array will create optgroups with options inside them.

$options = array(
 1 => 'bill',
 'fred' => array(
    2 => 'fred',
    3 => 'fred jr.'
 )
);
$this->Form->select('Model.field', $options);

In the above 2 => 'fred' will not generate an option element. You should enable the showParents attribute to show the fred option.

If you have multiple options that need to have the same value attribute, you can use an array of arrays to express this:

$options = array(
 array('name' => 'United states', 'value' => 'USA'),
 array('name' => 'USA', 'value' => 'USA'),
);

Parameters

string $fieldName: Name attribute of the SELECT
array $options optional array(): Array of the OPTION elements (as 'value'=>'Text' pairs) to be used in the SELECT element
