Multiple Parameters for a Shortcode

Lets look at the shortcode

[SH_TEST var1="somevalue" var2="someothervalue"]THE SHORTCODE CONTENT[/SH_TEST]

the shortcode handler function accepts 3 paramters

1. $atts – an array of attributes passed by the shortcode in our case:

   • $atts['var1'] is set to 'somevalue'
   • $atts['var2'] is set to 'someothervalue'

2. $content – is a string of the value enclosed with in the shortcode tags, in our case:
   –$content is set to THE SHORTCODE CONTENT

3. $tag – is a string of the shortcode tag, in our case:
   –$tag is set to SH_TEST

When I create a shortcode i usually define the default values and merge them with the values submitted by the shortcode tag ex:

add_shortcode('SH_TEST','SH_TEST_handler');
function SH_TEST_handler($atts = array(), $content = null, $tag){
    shortcode_atts(array(
        'var1' => 'default var1',
        'var2' => false
    ), $atts);

    if ($atts['var2'])
          return 'myothervalue';
    else
          return 'myvalue'; 
}
