function theme_form_element_label

Returns HTML for a form element label and required marker.

Form element labels include the #title and a #required marker. The label is associated with the element itself by the element #id. Labels may appear before or after elements, depending on theme_form_element() and #title_display.

This function will not be called for elements with no labels, depending on #title_display. For elements that have an empty #title and are not required, this function will output no label (''). For required elements that have an empty #title, this will output the required marker alone within the label. The label will use the #id to associate the marker with the field that is required. That is especially important for screenreader users to know which field is required.


$variables: An associative array containing:

  • element: An associative array containing the properties of the element. Properties used: #required, #title, #id, #value, #description.
