这是放置在函数中的短代码的基础。php或自定义插件。您需要对其进行编辑以满足您的需要：

//Shortcode function can be called whatever you want
function merchantname_shortcode( $atts ) {
    $atts = shortcode_atts( array(
        //Creates a arg "merchantname" with no default value. 
        //To use this arg in your shortcode use: $atts[\'merchantname\']
        \'merchantname\' => \'\'
    ), $atts, \'merchant-name\' );

    //Anything else you want goes in here. You can\'t echo anything in a shortcode. 
    //Assign it to a var like: 
    $String = "foo"; 
    $String .= "bar"; 

    return $String; 

    //Anything that is echoed will be displayed at the top of $content regardless 
    //to where the shortcode is.
}

//First arg is the text you would put in your page to display the shortcode. 
//Creates a shortcode [merchant-name]. 
//Second arg is the function used to create the shortcode.
add_shortcode( \'merchant-name\', \'merchantname_shortcode\' );
