This plugin provides a simple [meta] shortcode that allows you to fetch meta information for the current $post.
There are options to return a single value, multiple values joined by a user defined string, or a JSON string.
Examples:
[meta name="your_meta_field"]
This will return the value of “your_meta_field”. If the value is an array, it will return a comma separated list, unless you specify an alternative join string.
[meta name="your_meta_field" single="false"]
By default, [meta] will return a single value. If you have multiple meta fields with the same name, you can get them all by setting single=”false”.
[meta name="your_meta_field" single="false" json="true"]
This will return the JSON encoded value of “your_meta_field”.
[meta name="your_meta_field" single="false" join="|"]
This will return a pipe separated values of “your_meta_field”.
[meta name="your_meta_field" shortcode="false"]
By default, the value will be passed to do_shortcode, unless you turn if off.
[meta name="your_meta_field" filters="true"]
There are a couple filters available if you want to filter the value. They are called after do_shortcode and before any JSON/array handling.
They are on be default, but can be turned of with filters=”false”. The filters are “meta_fetcher_value” and “meta_fetcher_{$name}”.
