Question

I’ve read all the posts and the documentation on wp_enqueue script… but I’ve NEVER successfully gotten it to work.

This is what I’m doing that works:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js"</script>
<script type="text/javascript">
MY CODE
</script>

I know I know I know this isn’t the right way to to do it. So here’s what I’ve tried instead:

wp_enqueue_script('jquery');
wp_head();

No luck.

add_action('init', 'addscripts');
function addscripts() {
    wp_enqueue_script('jquery');
 }
wp_head();

No luck.

//in the theme's functions.php file
add_action('init', 'addscripts');
//add_action('wp_enqueue_scripts', 'addscripts'); //this also doens't work
function addscripts() {
    wp_enqueue_script('jquery');
 }

I’ve also tried the same approaches with the link to the external jquery library at google instead of the jquery tag. I’ve also tried de-registering and then registering the jquery script. Never works.

So I think these are the key questions:

1. Is there something wrong with my call to the wp_enqueue_script() function?

2. Where should it go? functions.php? header.php?

3. Is there a specific hook that I need to be using that’s not mentioned? 'init'? 'template_redirect'? 'wp_enqueue_scripts?'?

Please, no copy/pasted snippets from the codex! I’ve read it 50 times and tried them all. I promise.

I’m experimenting with a clean installation of WP3 and adding the above code to the default twentyeleven theme.

We have to assume that wp_enqueue works because I am not seeing pitchforks and torches on the horizon.

Such a thing would upset many developers.

So given that, let’s assume that it’s never being called.

Try adding something like this to the function that’s being called to unregister/register your new version of jQuery (not sure why you want to do this BTW).

<?php error_log( 'Something called me!' , 0 ); ?>

Then after you run your site and you expect your function to be called, go check your servers error log (/var/log/apache/yoursite-error.log or something) and see if that string shows up.

If it is showing up, we can move on to the next set of troubleshooting.
