[英]Drupal preprocess a commerce function
I need to preprocess a function from the module "commerce pricing attributes". 我需要从“商业定价属性”模块中预处理一个函数。
Here is the function : 这是函数:
function commerce_pricing_attributes_field_widget_form(&$form, &$form_state, $field, $instance, $langcode, $items, $delta, $element) {...}
I don't know how to preprocess this (if it's possible). 我不知道该如何预处理(如果可能的话)。
This function create some element in the back-office and the thing I want to do is to give a color to these elements in function of the type of the option the element is. 该函数在后台创建一些元素,而我想做的就是根据这些元素的选项类型为这些元素赋予颜色。 If it's an insurance option there is a color, if it's a room option another color.
如果是保险选项,则有一种颜色;如果是房间选项,则有另一种颜色。
I try to do this with an alter like this : function my_module_field_widget_commerce_pricing_attributes_custom_widget_form_alter(&$element, &$form_state, $context) {...}
我尝试使用类似的方法做到这一点:
function my_module_field_widget_commerce_pricing_attributes_custom_widget_form_alter(&$element, &$form_state, $context) {...}
But I can't have all the information I need (the type of the option). 但是我无法获得所需的全部信息(选项的类型)。
Is there any way to preprocess the function so I can use all the values they use in their module ? 有什么方法可以预处理函数,以便我可以使用它们在模块中使用的所有值吗?
I think you need to use this hook : hook_field_widget_form_alter 我认为您需要使用此钩子: hook_field_widget_form_alter
It allow you to override (or add) widget applied to a field 它允许您覆盖(或添加)应用于字段的小部件
function my_module_field_widget_form_alter(&$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 : dump variables to target exactly you want if you don't know structre of them 注意:如果您不知道变量的结构,则将其转储以精确地定位您想要的变量
