Method Detail

mixed	`$attributes`	—	Attributes (either a string or an array)
array	`$data`	—	Data used to populate the element's options, passed to loadOptions() method. Format: `$data = array('options' => array('option1', 'option2'));`

HTML_QuickForm2_Element_Select_Optgroup addOptgroup(
string
$label, [mixed

void addOption(
string
$text, string

)

Access: protected

[ Top ]

getType [line 341]

void getType(
)

Access: public

Overrides HTML_QuickForm2_Node::getType() (Returns the element's type)

[ Top ]

getValue [line 413]

mixed getValue(
)

Returns the value of the <select> element

Please note that the returned value may not necessarily be equal to that passed to setValue(). It passes "intrinsic validation" confirming that such value could possibly be submitted by this <select> element. Specifically, this method will return null if the elements "disabled" attribute is set, it will not return values if there are no options having such a "value" attribute or if such options' "disabled" attribute is set. It will also only return a scalar value for single selects, mimicking the common browsers' behaviour.

Return: "value" attribute of selected option in case of single select, array of selected options' "value" attributes in case of multiple selects, null if no options selected
Access: public

Overrides HTML_QuickForm2_Node::getValue() (Returns the element's value)

[ Top ]

loadOptions [line 485]

HTML_QuickForm2_Element_Select loadOptions(
array
$options)

Loads <option>s (and <optgroup>s) for select element

The method expects a array of options and optgroups:

 array(
     'option value 1' => 'option text 1',
     ...
     'option value N' => 'option text N',
     'optgroup label 1' => array(
         'option value' => 'option text',
         ...
     ),
     ...
 )

If value is a scalar, then array key is treated as "value" attribute of <option> and value as this <option>'s text. If value is an array, then key is treated as a "label" attribute of <optgroup> and value as an array of <option>s for this <optgroup>.

If you need to specify additional attributes for <option> and <optgroup> tags, then you need to use addOption() and addOptgroup() methods instead of this one.

Throws: HTML_QuickForm2_InvalidArgumentException if junk is given in $options
Access: public

Parameters:

array $options —
