从 WordPress 选项表中获取自定义选项

Question

I have custom options being stored in the database like this:

option_name: shop_details

option_value: {"shop_name":"My shop","shop_slug":"my-shop","shop_description":"This is my cool shop.","shop_start_date":"2019-10-03","shop_end_date":"2019-10-11","shop_owner":"1","taxonomy":"shop"}

I am trying to display some of this information on the front-end, like this:

$shop_options = get_option('shop_details');
echo $shop_options['shop_description'];

But I am getting this error:

Warning: Illegal string offset 'shop_description' in D:\www\my-shop\wp-content\themes\shop-city\taxonomy-shop.php on line 32 {

What am I doing wrong?

Answer 1

The value you are getting in $shop_options is a JSON format, so you have to decode it first then you can get the array. Use:

$shop_options = get_option('shop_details');
$shop_options = json_decode($shop_option);

If you call json_decode($somestring) you will get an object and you need to access like $object->key , but if you call json_decode($somestring, true) you will get a dictionary and can access like $array['key']
