How to: show/hide a widget in WordPress with jQuery

In a previous post I talked about how to show/hide a single div html code with a search inside. Today I’d like to show you how I implemented jQuery into my new theme.

Published

on

As seen in the current theme, I am using jQuery to animate the show/hide or as known as the css style display: none;.

Since I am using a custom child theme on my site, and have Hybrid theme as my parent, the widgets or sidebar section is different than may be in your theme. But just apply the the style’s as follows to your theme.

First make sure that your WordPress site is calling jQuery, by plugging in this code into your header.php file above the <?php wp_head(); ?> text:

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

Then anywhere above the </head >, plug this code in:

<script type="text/javascript">
function toggleWidgets() {
	$('#primary h3.widget-title').addClass('plus');

	$('#primary h3.widget-title').click(function() {
		$(this).toggleClass('plus').toggleClass('minus').next().toggle(180);
	});

}
$(document).ready(function() {
	toggleWidgets();
}
</script>

That’s it. Pretty simple huh.

So lets go over what the code does.

$('#primary h3.widget-title').addClass('plus');

This line finds all <h3> tags with the class widget-title inside the ID parameter of #primary and adds a class of plus.

Then

$('#primary h3.widget-title').click(function() {
		$(this).toggleClass('plus').toggleClass('minus').next().toggle(180);
	});

Will apply a click function. When the H3 tag is clicked it will remove the class plus and add the class minus.

Then the code that says .next will then toggle the “next” element after the <h3> title.

Jon Asked: How to add thumbnails above post on the THiCK theme

Published

on

I was asked by a reader:

I’m using the THiCK theme for my new design blog. I noticed you were able to add thumbnail images above your blog posts on the home page. What would I need to do to enable this on my blog?

Well Jon, this can be done very simple, since the theme is already using the Tim Thumb script.

What you will need to do is find in your index.php file, the second loop. Which you can find on line 40.

<?php query_posts('offset=1&showposts=' . get_option('woo_other_entries') . '&cat=-' . $GLOBALS['ex_asides'] ); ?>

<?php while (have_posts()) : the_post(); ?>	

	<div class="post">
		<h2><a title="Permanent Link to <?php the_title(); ?>" href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></h2>
		<div class="post-meta"><?php the_time('j/m/y'); ?> <span>|</span> <?php comments_popup_link('0 Comments', '1 Comment', '% Comments'); ?></div>
		<?php the_excerpt(); ?>
	</div>

<?php endwhile; ?>

Now we are going to add in the code. At line 43 we are going to add:

<?php if (get_option('woo_resize')) { // Check if we should use the image resizer ?>
                    <a title="Continue reading this entry..." href="<?php the_permalink() ?>" rel="bookmark"><img src="<?php echo bloginfo('template_url'); ?>/thumb.php?src=<?php echo get_post_meta($post->ID, "image", $single = true); ?>&amp;h=80&amp;w=280&amp;zc=1&amp;q=90" alt="<?php the_title(); ?>" /></a>
                <?php } else { ?>
                    <a title="Continue reading this entry..." href="<?php the_permalink() ?>" rel="bookmark"><img src="<?php echo get_post_meta($post->ID, "image", $single = true); ?>" alt="<?php the_title(); ?>" /></a>
                <?php } ?>

That’s it, just make sure that in the THiCK options panel you choose the “resize” option, or the image might break the layout. Or you may change the this code: $post->ID, "image", to: $post->ID, "image_thumb", and use a separate image for the lower blog.
