This can be achieved using hook_node_view
<?php
function ji_custom_node_view($node, $view_mode, $langcode) {
if($view_mode != 'full'){
return;
}
switch ($node->type) {
case 'blood_donor_form':
foreach ($node->content as $field_name => $field_options) {
if(isset($field_options['#title']) && isset($field_options[0]['markup'])) {
$node->content["$field_name"]['#title'] = $field_options['#title']
."<div class = 'ji-field-description-suffix'>".$field_options[0]['markup']['#suffix']."</div>";
unset($node->content["$field_name"][0]['markup']['#suffix']);
}
}
break;
}
}
?>The code alters each field attaching the description just after the label of the field, if present. Also prefixes with a div class for custom css option for the description fields.
