Too Much jQuery Loading WordPress

Dan Davies answers:

With regards to the jQuery issue, try putting the following code before

<?php wp_head(); ?>

in your header.php file:

<?php wp_enqueue_script("jquery"); ?>

That should prevent multiple instances of jQuery being loaded.

For the videos - if screenflow doesn't allow you to export video as .swf, you'll have to look at getting a piece of software to convert .mov files to .swf files. You can find plenty of pieces of software that do that by doing a [[LINK href="http://www.google.com/search?q=.mov+to+.swf"]]Google search[[/LINK]].

Alternatively, you could look into using [[LINK href="http://www.vimeo.com/plus"]]Vimeo Plus[[/LINK]], which allows you to privatise your videos and lock them to a particular domain.

I hope that helps!

@Darfuria is on the right track with the addition of the following code.

wp_enqueue_script('jquery');

One change I'd make is to put the following in your functions.php file:


function pj_add_jquery_scripts () {
wp_enqueue_script('jquery');
}
add_filter ('wp_head', 'pj_add_jquery_scripts', 1);


This basically does the same thing, but doesn't muddy up the template files. The problem is, this won't necessarily solve your multiple loads of jQuery. This will limit the amount of loads you get for developers who use this function to call jQuery in their plugin, but a lot of times developers write script tags out to include it. You'd have to go through each of the plugins you have installed and find where they're including the jQuery library and make sure they're using wp_enqueue_script() too. If they're not, you could change it (or just delete the call all together), but you'd have to go through this process whenever the plugin developer releases an upgrade (or never upgrade the plugins you modify.

As for the videos, I would seriously look into using VideoPress. It's a paid service offered at http://www.wordpress.com (preview features at http://videopress.com/). It can handle very high quality video and it works straight from within your self-hosted WordPress install.

Hi Spencer,

The issue of multiple instances of jQuery being loaded, is being caused by the plugin [[LINK href="http://wordpress.org/extend/plugins/community-links-feed/"]]Community Links Feed[[/LINK]]
You can resolve that, by editing the line 106 of cj_community_links.php in the wp-content/plugins/community-links-feed/
from
echo '<script type="text/javascript" src="'.$clpath.'jquery-1.3.2.min.js"></script>'."\n";
to
// echo '<script type="text/javascript" src="'.$clpath.'jquery-1.3.2.min.js"></script>'."\n";

This will basically prevent the plugin from loading its own jQuery file on each page load. The theme already includes one instance of jQuery, so the plugin would function properly. This is a bug in the program, as it should have used the WordPress functions to include jQuery in the page.

As for the video, I would highly suggest having a look at [[LINK href="http://www.vimeo.com/plus"]]Vimeo Plus[[/LINK]]. If you convert .mov to .flv, the quality would definitely be lowered, and I wouldn't suggest it. Plus, it would also help reducing the bandwidth consumed in hosting, if you plan to host the video yourself.
