To include a known shortcode in a custom page/post template file as part of the content, you need to use do_shortcode()
:
echo do_shortcode( "[a-registered-shortcode-name]" );
The function do_shortcode()
parses shortcodes with their registered hooks in the content and return the content with the parsed shortcodes output. Below example use do_shortcode()
to parse multiple shortcodes in a piece of content.
echo do_shortcode( "<p>Shortcode example 1: ['shortcode-name1']</p><p>Shortcode example 2:['shortcode-name2']</p>" );
If you write the shortcode string in the article content just like you what you do in WordPress edit page, it will not be parsed.
<!-- The shortcode below is just a plain text in the page/post template -->
<p>
["a-registered-shortcode-name"]
</p>
When editing a page/post in WordPress, the shortcode string works because it will be processed by the the_content()
in a template file when it is displayed. the_content()
will call do_shortcode()
to process the shortcodes inside the content.
