WordPress RSS Feed来自一个特定的短代码

Question

I want to make function that will display RSS Feed content from one specific shortcode. Example, I have:

[text1]Text One[/text1]
[text2]Text Two[/text2]

Now, content of text2 shortcode should display in RSS Feed.

Function I have so far:

function custom_rss($content) {
if(is_feed()){
$content = "Custom Text";
}
return $content;
}
add_filter('the_excerpt_rss', 'custom_rss');
add_filter('the_content', 'custom_rss');

Ok, this works, I get "Custom Text" in the RSS Feed.

What function will call content from specific shortcode, in example, from [text2]Text Two[/text2] .

Answer 1

Wordpress Codex:
shortcode atts and add_shortcode

function bartag_func( $atts ) {
     extract( shortcode_atts( array(
          'foo' => 'no foo',
          'baz' => 'default baz'
     ), $atts ) );
     return "foo = {$foo}";
}
add_shortcode( 'bartag', 'bartag_func' );

Answer 2

Try this code:

function text( $atts, $content = null ) {
    if (is_feed()) {
        return $content;
    } else {
        return '<div class="text" style="display: block; margin-left: 160px;">'.$content.'<br><br></div>';
    }
}
add_shortcode( 'text', 'text' );
