wp_enqueue conflicts with shortcodes

<?php add_filter('the_posts', 'add_script_conditionally');

//search for the shortcode. if it exists, add the js
function add_script_conditionally($posts){
    if (empty($posts)) return $posts;

    $shortcode_found = false; 
    foreach ($posts as $post) {
        if (stripos($post?>post_content, '[plugin_name]')) {
            $shortcode_found = true;
            break;
        }
    }

    if ($shortcode_found) {
        //enque main script
        wp_enqueue_script('swfObject789', $home_url.'/wp-content/plugins/plugin_name/js/swfobject.js',false,null);
    }

    return $posts;
}

function add_slideshow($params=array()) {

    echo 'test';

}

//register shortcode
add_shortcode('plugin_name', 'add_slideshow');

?>

[plugin_name]

[plugin_name id="6"]

Here, you are searching specifically for [plugin_name]. When you add a parameter, your strings no longer match ([plugin_name] != [plugin_name ...] ).

if (stripos($post->post_content, '[plugin_name]')) {
    $shortcode_found = true;

if ($shortcode_found) {
    //enque main script
    wp_enqueue_script('swfObject789', $home_url.'/wp-content/plugins/plugin_name/js/swfobject.js',false,null);
}

If you always want the script included, remove the conditional.

If you only want the script included when the shortcode has been used in the post content, just remove the closing ] from your stripos string – or if you want to be more precise use a regular expression (preg_match) to match [plugin_name .*].
