问题描述
我有以下一段代码:
<?php echo get_custom_field('Services'); ?>
有三种可能的字符串输出:food"、drink"、food &drink".
There are three possible string outputs for this: "food", "drink", "food & drink".
我想用小图标(例如喝"的玻璃杯)替换这些字符串.
I would like to replace these strings with small icons (e.g. a glass for "drink").
有没有一种简单的方法可以用 PHP 做到这一点?
Is there a simple way of doing this with PHP?
谢谢
推荐答案
您可以通过数组映射值:
You could map the values via an array:
$items = array(
"Food" => "plate.png",
"Drink" => "glass.png",
"Food & Drink" => "tray.png"
);
然后在回显图像时执行查找:
Then perform your look-up when echoing the image:
<img src="<?php echo $items[ get_custom_field('Services') ]; ?>" />
