J'ai pu y parvenir après beaucoup de travail et en essayant chaque méthode publiée en utilisant une astuce intelligente que j'ai trouvée profondément sur Internet sur un autre site: http://e9p.net/altering-individual-radio-or-checkbox-items-drupal- 7 fapi , à utiliser #after_build
pour pouvoir modifier les radios individuelles de l'élément de forme une fois qu'elles sont un tableau de rendu drupal.
Je voulais que chaque radio soit emballée dans un conteneur avec une classe, alors j'ai utilisé #prefix
et #suffix
pour cela:
function _MYMODULE_options_after_build(&$element, &$form_state){
// Each renderable radio element.
foreach (element_children($element) as $key) {
$element[$key]['#prefix'] = '<div class="class1 class2">';
$element[$key]['#suffix'] = '</div>';
}
// Always return the element to render in after_build callbacks.
return $element;
}
exemple d'utilisation:
$form['style'] = array(
'#type' => 'radios',
'#title' => t('Select your style option'),
'#options' => $style_options,
'#default_value' => NULL,
'#required' => TRUE,
'#after_build' => array(
'_MYMODULE_options_after_build'
)
);
Cependant, si vous souhaitez uniquement que l' input
élément ait la classe, vous devez implémenter la solution que j'ai publiée sur drupal.org à https://api.drupal.org/comment/60197#comment-60197 pour autoriser l'utilisation des #options_attributes correctement pour les options individuelles. Code de re-publication ici:
function MYMODULE_element_info_alter(&$info) {
// You might want more advanced logic here, to replace instead of override altogether,
// in case other modules have already altered the core info.
$info['radios']['#process'] = array('safetycal_request_a_quote_process_radios');
}
function MYMODULE_process_radios($element) {
// for some reason when I take over processing the radios the structure
// is slightly different than with form_process_radios and it needs to be fixed
if(isset($element['element'])){
$element = $element['element'];
}
if (count($element ['#options']) > 0) {
$weight = 0;
foreach ($element ['#options'] as $key => $choice) {
// Maintain order of options as defined in #options, in case the element
// defines custom option sub-elements, but does not define all option
// sub-elements.
$weight += 0.001;
$element += array($key => array());
// Generate the parents as the autogenerator does, so we will have a
// unique id for each radio button.
$parents_for_id = array_merge($element ['#parents'], array($key));
$element [$key] += array(
'#type' => 'radio',
'#title' => $choice,
// The key is sanitized in drupal_attributes() during output from the
// theme function.
'#return_value' => $key,
// Use default or FALSE. A value of FALSE means that the radio button is
// not 'checked'.
'#default_value' => isset($element ['#default_value']) ? $element ['#default_value'] : FALSE,
// changed below line to use the #options_attributes array
'#attributes' => $element['#option_attributes'][$key],
'#parents' => $element ['#parents'],
'#id' => drupal_html_id('edit-' . implode('-', $parents_for_id)),
'#ajax' => isset($element ['#ajax']) ? $element ['#ajax'] : NULL,
'#weight' => $weight,
);
}
}
return $element;
}
exemple d'utilisation:
$style_options = array(
'red' => 'Red',
'green' => 'Green',
'yellow' => 'Yellow'
);
$style_option_attributes = array(
'red' => array(
'class' => array(
'red-class'
)
),
'green' => array(
'class' => array(
'green-class'
)
),
'yellow' => array(
'class' => array(
'yellow-class'
)
)
);
$form['style'] = array(
'#type' => 'radios',
'#title' => t('Select your style option'),
'#options' => $style_options,
'#option_attributes' => $style_option_attributes,
'#default_value' => NULL,
'#required' => TRUE,
'#attributes' => array(
'class' => array(
'radio-element-class'
)
)
);
