Drupal预处理商务功能 [英] Drupal preprocess a commerce function

问题描述

我需要从商业定价属性模块中预处理功能。

I need to preprocess a function from the module "commerce pricing attributes".

这里是函数：

function commerce_pricing_attributes_field_widget_form(&$form, &$form_state, $field, $instance, $langcode, $items, $delta, $element) {...}

我不知道如何进行预处理（如果可能的话）。

I don't know how to preprocess this (if it's possible).

此函数在后台创建一些元素，然后我要做的就是根据元素的选项类型为这些元素赋予颜色。如果是保险选项，则有一种颜色，如果是房间选项，则有另一种颜色。

This function create some element in the back-office and the thing I want to do is to give a color to these elements in function of the type of the option the element is. If it's an insurance option there is a color, if it's a room option another color.

我尝试使用这样的修改来做到这一点：$ b​​ $ b function my_module_field_widget_commerce_pricing_attributes_custom_widget_form_alter（& $ element，& $ form_state，$ context）{...}

I try to do this with an alter like this : function my_module_field_widget_commerce_pricing_attributes_custom_widget_form_alter(&$element, &$form_state, $context) {...}

但是我可以没有我需要的所有信息（选项的类型）。

But I can't have all the information I need (the type of the option).

是否可以对函数进行预处理，以便可以在其使用中使用它们所使用的所有值模块？

Is there any way to preprocess the function so I can use all the values they use in their module ?

推荐答案

我认为您需要使用此钩子： hook_field_widget_form_alter

I think you need to use this hook : hook_field_widget_form_alter

它允许您覆盖（或添加）应用于字段的窗口小部件

It allow you to override (or add) widget applied to a field

function my_module_field_widget_form_alter(&$element, &$form_state, $context) {

  if ($context['field']['type'] == 'mytype') { // you can use another condition on field name or whatever 

    // Loop through the element children (there will always be at least one).
    foreach (element_children($element) as $key => $child) {
      // Add the new process function to the element
      $element[$key]['#process'][] = 'my_custom_callback_field_widget_process';
    }
  }
}

function my_custom_callback_field_widget_process($element, &$form_state, $form){
// do your stuff
  return $element;
 }

NB：如果您不知道structre，则转储变量以精确定位您想要的目标

NB : dump variables to target exactly you want if you don't know structre of them
