Wordpress get_option 到变量而不使用未定义的常量 [英] Wordpress get_option to variable without use of undefined constant

问题描述

我的插件有很多选择.我使用 get_option 并将其存储为数组，以便更易于使用.

My plugin i have many options. I use get_option and store it as an array so its easier to use.

function woomps_get_options() {
    $options = array(
        'sub01' => get_option(woomps_sub01),
        'sub02' => get_option(woomps_sub02),
        );
    return $options;
}

这会为每一行生成此通知:

This produces this notice for each line:

[TIME] PHP Notice:  Use of undefined constant woomps_sub01 - assumed 'woomps_sub01' in "DOMAIN"\settings\options.php on line 9

我不明白为什么我应该先定义 woomps_sub01 或者我应该如何定义它.但我的问题是:为什么这不是获得 WP 选项的正确方法，什么是更好的方法?

I dont understand why i should define woomps_sub01 first or how i should define it. But my question is rather: Why is this not a correct way to get a WP option and what is the better way?

推荐答案

PHP 只是告诉您正在向函数传递一个未定义的常量，但您可能将 'woomps_sub01' 作为字符串传递给函数.

PHP is simply telling that you're passing to the function a undefined constant but probably you meant 'woomps_sub01' as a string.

只要加上这样的引号get_option('woomps_sub01')，通知就会消失.

Just put quotes like this get_option('woomps_sub01') and the notice will go away.
