使數組與陣列

Question

我想在我的Drupal文件夾中創建大量數組。但我不知道如何做到這一點。基本上，它總是一樣的結構。

$form['actions']['saveasdraft']['#type'] = 'submit'; 
$form['actions']['saveasdraft']['#access'] = true; 
$form['actions']['saveasdraft']['#value'] = 'Save as Draft'; 
$form['actions']['saveasdraft']['#weight'] = 11; 
$form['actions']['saveasdraft']['#submit'][0] = 'node_fiche_form_submit'; 

$form['actions']['saveascurrent']['#type'] = 'submit'; 
$form['actions']['saveascurrent']['#access'] = true; 
$form['actions']['saveascurrent']['#value'] = 'Save as New version'; 
$form['actions']['saveascurrent']['#weight'] = 12; 
$form['actions']['saveascurrent']['#submit'][0] = 'node_fiche_form_submit'; 

... 

有沒有更簡單的方法來做到這一點？

Answer 1

「正確」的方式做到這一點是這樣的（見Drupal coding standards）：

$form['action']['saveasdraft'] = array(
    '#type' => 'submit', 
    '#access' => TRUE, 
    '#value' => 'Save as Draft', 
    // etc... 
); 

$form['action']['saveascurrent'] = array(
    '#type' => 'submit', 
    '#access' => TRUE, 
    '#value' => 'Save as New version', 
    // etc... 
); 

就是這樣Drupal的核心模塊做到這一點（這是我見過的所有貢獻的模塊）。

編輯

如果你擔心重複代碼，你將能夠做的最好的是設置一些默認值...應該省下幾百行:)

$defaults = array('#type' => 'submit', '#access' => TRUE, /* etc... */); 

$form['action']['saveasdraft'] = $defaults + array(
    '#value' => 'Save as Draft' 
); 

$form['action']['saveascurrent'] = $defaults + array(
    '#value' => 'Save as New version' 
); 

希望有道理

Answer 2

嘗試使用DRY規則（不要重複自己）。你可以做到這一點，例如。通過創建函數將返回正確的元素被輸入到更大的陣列那樣：

function form_element($value, $weight, $type = 'submit', $access = true, 
    $submit = 'node_fiche_form_submit') { 
    return array(
     '#type' => $type, 
     '#access' => $access, 
     '#value' => $value, 
     '#weight' => $weight, 
     '#submit' => array($submit), 
    ); 
}; 

，然後你可以使用它像：

$form['actions']['saveasdraft'] = form_element('Save as Draft', 11); 
$form['actions']['saveascurrent'] = form_element('Save as New version', 12); 
// ...and so on 

的證明見this codepad。

PS。當然，你應該爲輔助函數創造一些更有意義且不太矛盾的名稱，但這種方法是最短的一種。
