Drupal:*.api.php 中的 hook_ 函数是否被调用过?
在 Drupal 7 中,每个核心模块都有一个 *.api.php
文件,其中 * 是模块的名称。例如,
modules/node/node.api.php
modules/path/path.api.php
这些文件有什么用?它们包含以 hook_
开头的函数,以及(我认为)模块调用的钩子的名称。例如,
modules/system/system.api
有
function hook_entity_view($entity, $type, $view_mode, $langcode) {
$entity->content['my_additional_field'] = array(
'#markup' => $additional_field,
'#weight' => 10,
'#theme' => 'mymodule_my_additional_field',
);
}
一个由系统调用的 entity_view
钩子,您可以在自己的模块中实现该钩子,但是(它不会出现)曾经调用过 hook_entity_view
。
这些功能是做什么用的。他们被系统调用过吗?如果是的话,什么时候?如果没有,他们为什么在那里?
In Drupal 7, every core module has a *.api.php
file, where * is the name of the module. For example
modules/node/node.api.php
modules/path/path.api.php
What are these files for? They contain functions that start with hook_
, and the name of a hook that (I think) the module invokes. For example
modules/system/system.api
has
function hook_entity_view($entity, $type, $view_mode, $langcode) {
$entity->content['my_additional_field'] = array(
'#markup' => $additional_field,
'#weight' => 10,
'#theme' => 'mymodule_my_additional_field',
);
}
There's an entity_view
hook that's invoked by the system which you may implement in your own modules, but (it doesn't appear) that hook_entity_view
is ever called.
What are these function for. Are they ever called by the system? If so, when? If not, why are they there?

不,这只是描述模块挂钩的文档文件。
关于hook_entity_view:您可以将其添加到自定义模块中:YOURMODULENAME_entity_view(...)。
Nope, it's just documentation files that describe hooks by modules.
About hook_entity_view: you can add it in custom module: YOURMODULENAME_entity_view(...).
