Image Shortcode in Post

Hi,

The following code should add an [tppubimage] shortcode. You can add the code to the functions.php of your theme or create a new plugin with it:

/** 
 * Shortcode for displaying the image of a single publication
 * 
 * possible values of $atts:
 *      id (INT)        id of a publication
 *      key (STRING)    bibtex key of a publication 
 * 
 * If neither is given, the publication of the most recent [tpsingle] will be reused
 * 
 * @param array $atts
 * @return string
*/ 
function tp_pubimage_shortcode ($atts) {
    global $tp_single_publication;
    $param = shortcode_atts(array(
       'id' => 0,
       'key' => '',
    ), $atts);

    $publication = tp_shortcodes::set_publication($param, $tp_single_publication);

    if ( isset($publication['abstract']) ) {
        return '<img src="' . tp_html::prepare_text($publication['image_url']) . '" alt=""/>';
    }
    return;
}

add_shortcode('tppubimage', 'tp_pubimage_shortcode');
