1 common.inc element_set_attributes(array &$element, array $map)

Sets HTML attributes based on element properties.


$element: The renderable element to process.

$map: An associative array whose keys are element property names and whose values are the HTML attribute names to set for corresponding the property; e.g., array('#propertyname' => 'attributename'). If both names are identical except for the leading '#', then an attribute name value is sufficient and no property name needs to be specified.
