unable to wp_enqueue_script('suggest');

Question

i'm not able to enqueue the built in autosuggest script in my wordpress theme.

wp_enqueue_script('suggest');

my current workaround for that problem is to deregister, register manually an then enqueue it – like so:

wp_deregister_script('suggest');
wp_register_script('suggest', '/wp-includes/js/jquery/suggest.js');
wp_enqueue_script('suggest');

i can't figure out how to solve this problem, because i get no error at all (WP_DEBUG defined TRUE)

thanks for your thoughts, hans

//update

sorry for being a bit cloudy with the description of my problem:

i am working on a wiki-like thing based on wordpress. there is one page where users can upload new images and tag them (this is where i need the suggest.js).

the templatefile for this page looks like:

<?php
//enqueue scripts + styles
wp_enqueue_script('uploadify', get_bloginfo('template_directory') . '/js/uploadify/jquery.uploadify.v2.1.0.js', array('jquery'), null, null);
wp_enqueue_script('swfobject', get_bloginfo('template_directory') . '/js/uploadify/swfobject.js', array('jquery'), null, null);
wp_enqueue_script('jcrop');
wp_enqueue_style('jcrop');
wp_deregister_script('suggest'); //workaround
wp_register_script('suggest', '/wp-includes/js/jquery/suggest.js'); //workaround
wp_enqueue_script('suggest'); //workaround

...

get_header();

page content that uses scripts & styles

get_footer();
?>

at the very beginning of the file i'm enqueueing the additional styles/scripts i need for that single page. (other "basic" scripts + styles get enqueued in my functions.php)

enqueueing jcrop for example works without any problems…

As stated on WP Devel, you should always use the appropriate hooks. Else no child theme could deregister the script later.

// In your functions.php file
function add_suggest_script()
{
    wp_enqueue_script( 'suggest', get_bloginfo('wpurl').'/wp-includes/js/jquery/suggest.js', array(), '', true );
}
add_action( 'wp_enqueue_scripts', 'add_suggest_script' );

This will load the script from the includes folder and stick in your footer (where a script ideally should be).

You could also use includes_url() in the function above. This will also check for SSL connections.

Note: You'll have to have wp_head(); present. Inside there the mentioned hook gets fired.
