用数组制作数组

Question

我想在我的 Drupal 文件夹中创建很多数组。但我不知道该怎么做。基本上，它总是相同的结构。

$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'; 

...

有没有更简单的方法来做到这一点？

Answer 1

“正确”的方法是这样的（参见 Drupal 编码标准）：

$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...
);

就是这样Drupal 核心模块可以做到这一点（以及我见过的所有贡献模块）。

编辑

如果您担心重复代码，您能做的最好的事情就是设置一些默认值...应该节省几百行:)

$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'
);

希望这是有道理的

尝试采用 DRY（不要重复自己）规则。你可以这样做，例如。通过创建将返回正确元素以输入到更大数组中的函数，如下所示：

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),
    );
};

然后您可以像这样使用它：

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

请参阅 此键盘作为证明。

附言。当然，您应该为辅助函数发明一些更有意义且冲突更少的名称，但该方法是最短的方法之一。
