Drupal render() - 使打印内容 ucfirst

Question

我有一个 drupal 模板，可以呈现如下内容：

<?php $field_collection_state_info = reset($content['field_state_information']['0']['entity']['field_collection_item']);  ?>  
<?php print render($field_collection_state_info['field_state_name']); ?>

但我想运行 php ucfirst()，所以所有呈现的内容都在第一个字母上大写。

我试过这个：

<?php print ucfirst(render($field_collection_state_info['field_state_name'])); ?>

但这没有用。

我应该如何做到这一点？

非常感谢任何建议。

我认为您必须在调用 render() 之前更改渲染数组的内容：

// the 'und' part is depending on the translation of the node
$field_collection_state_info['field_state_name']['und'][0]['value'] =
ucfirst($field_collection_state_info['field_state_name']['und'][0]['value']);
// render
print render($field_collection_state_info['field_state_name']);

// or you could try to modify the safe_value part of the array depending on your
// filter settings for the field
$field_collection_state_info['field_state_name']['und'][0]['safe_value'] =
ucfirst($field_collection_state_info['field_state_name']['und'][0]['safe_value']);
// render
print render($field_collection_state_info['field_state_name']); 

编辑尝试将此添加到您的template.php，它会更改使用hook_preprocess_node() 的collection_field 的值：

function YOURTHEME_preprocess_node(&$vars) {
  if($vars['type'] == 'YOUR-CONTENT-TYPE') {    
     // you might need to replace the field_content_block with the name of your field <field_state_information>
     $data = reset($vars['content']['field_content_block'][0]['entity']['field_collection_item']);
     // turn the first character to uppercase
     $data['field_text']['#object']->field_text['und'][0]['value'] = ucwords($data['field_text']['#object']->field_text['und'][0]['value']);
    // set the data in the array, like I said above your might need to change the `field_collection_block` to `field_state_information`
    $vars['content']['field_content_block'][0]['entity']['field_collection_item'] = $data;
  } 
}
