在函数中。PHP→

Code for class.settings-api.php

但我认为子菜单没有注册，这就是后端没有填充任何内容的原因。看这里→enter image description here

解决方法是什么？

我对WeDevs的事情一无所知，但我对设置API本身有点了解。

尽管如此，我还是有一个不确定的答案。在您的wedevs_plugin_page() 函数，执行$settings_api 对象需要显示哪个设置部分的参数？喜欢$settings_api->show_navigation(\'wedevs_basic\');?

或者，对象实例化本身可能需要一个参数？喜欢$settings_api = new WeDevs_Settings_API(\'wedevs_basic\');?

同样，我不知道WeDevs框架，但在admin\\u init函数期间创建的WeDevs\\u Settings\\u API对象稍后可以与在options page函数中创建的另一个WeDevs\\u Settings\\u API对象通信，这似乎很奇怪。除非$settings_api->admin_init(); 做一些很酷的事情来促进交流，只是这里似乎缺少了一些东西。

EDIT:

好的，我认为你不应该使用设置API插件（比如不要激活它），而是应该在你自己的主题中使用它作为你自己代码的示例。我想这就是作者所说的“这个插件是为开发人员而不是一般用户设计的”

无论如何，去上课吧。设置api。php文件，并将其包含在您的主题中（我认为您已经在这样做了）。不要更改此文件中的任何内容。

然后在o函数中。php文件，只需去掉所有程序性的东西并使用oop示例即可。改为php文件。比如从该文件中复制代码并将其粘贴到o函数中。php文件。

现在编辑o形函数。php文件，以满足您的需要。您应该做的第一件事是将类的名称从“WeDevs\\u Settings\\u API\\u Test”更改为对主题更具描述性的名称。不要忘记更改条件中的类名-if ( !class_exists(\'WeDevs_Settings_API_Test\' ) ):

然后更改的参数add_options_page( \'Settings API\', \'Settings API\', \'delete_posts\', \'settings_api_test\', array($this, \'plugin_page\') );

您需要更改第一个、第二个和第四个参数，这些参数分别是页面标题、菜单标题和菜单段塞。特别是slug必须是独一无二的。

然后可以根据需要更改节和字段。

所以，只要您从oop示例中复制代码，就可以快速回顾一下。php，您需要更改类的名称，更改add_options_page(), 更改中的节名称function get_settings_sections(), 并更改中的字段数据function get_settings_fields(). 请勿触摸此代码中的任何其他内容。

现在，在您使用的位置之后，使用新类实例化一个对象locate_template(), 像这样：

locate_template( \'class.settings-api.php\', true );
locate_template( \'o-functions.php\', true );
new My_Settings_API();
请注意，当我在o函数中重命名该类时。php，我称之为“My\\u Settings\\u API”。所以你需要使用你给它起的任何名字。
