Tips & Tricks
Creating a custom widget
Today let’s learn a simple quick trick on how to create a custom widget. For my example I will show you how I created my Showcase widget located in the middle, to the right of the posts.
First under your functions.php
file type in the following:
<?php // Custom Widget function MyCustomWidget() { ?> <li class="widget"> <h2 class="heading">Latest Showcase</h2> <ul> <?php include(TEMPLATEPATH . '/includes/showcase.php'); ?> </ul> </li> <?php } register_sidebar_widget('The Custom Widget for Showcase', 'MyCustomWidget'); ?>
- Always make sure your code is between the
<?php
and?>
for it to work. - Once we call the function, the rest is assuming html code that you may or may not need.
- For instance, you may just put in a picture and call it a day. But my code starts with
<li<
because my sidebar’s start and end with<ul<
. - Any way, once your done, just set the final “
register_sidebar_widget('the widget title', 'the name of the function');
“
That’s it! Now you have a custom widget with what ever you want!
Tips & Tricks
Limit the characters that display on the_title
Ever wanted to display the title of a post somewhere but limit the amount of characters that are shown? For instance, this post has a very long title, and if I were to use <?php echo the_title() ?>
it would show as follows: Limit the characters that display on the_title.
That may not fit well on one line in lets say a widget or small width div
. So here is a neat trick you can use:
<?php $title = the_title('','',FALSE); echo substr($title, 0, 11); ?>
Pretty simple huh, just note the bold numbers, in this case 11 character would output like this: Limit the c.
Thanks to Tattershall Way for this snippet.
Tips & Tricks
Can′t add pagination on WooThemes Thick Theme
Everything I have tried has led to nothing. And I have tried six way’s from Sunday to get my main posts to paginate.
example one:
<?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; query_posts('offset=1&showposts=' . get_option('woo_other_entries') . '&cat=-' . $GLOBALS['ex_asides'] . '&paged=$paged' ); ?>
example two:
<?php global $myOffset; global $wp_query; $myOffset = 1; $paged = intval(get_query_var('paged')) ? get_query_var('paged') : 1; $temp = $wp_query; $wp_query= null; $wp_query = new WP_Query(); $wp_query->query(array( 'offset' => $myOffset, 'category__not_in' => array($GLOBALS['ex_asides'],7,84), 'paged' => $paged, 'showposts' => get_option('woo_other_entries'), )); ?>
example three:
<?php global $myOffset; $myOffset = 1; $wp_query = new WP_Query(); $wp_query->query(array( 'offset' => $myOffset, 'category__not_in' => array($GLOBALS['ex_asides'],7,84), 'paged' => $paged, 'showposts' => get_option('woo_other_entries'), )); ?>
And after those tries, I just can’t get more pages beyond the option’s that I choose, and can only pull an archive via the browse more link.
Any suggestions or anything?
Tips & Tricks
Pulling custom fields from outside the loop
In the last post “Creating a custom widget” I showed you how to create a custom widget. Well in this post I will show you how I used my custom widget to display all post with a certain custom field from outside the WordPress loop.
In the last post I used this tag:
<?php include(TEMPLATEPATH . '/includes/showcase.php'); ?>
Now I will show you what the file showcase.php
has:
<ul> <?php global $wpdb; $sql = "SELECT wposts.* FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta WHERE wposts.ID = wpostmeta.post_id AND wpostmeta.meta_key = 'gallery-url' AND wposts.post_status = 'publish' AND wposts.post_type = 'post' ORDER BY wposts.post_date DESC LIMIT 8"; $pageposts = $wpdb->get_results($sql, OBJECT); $output = $pre_HTML; foreach ($pageposts as $post) : setup_postdata($post); ?> <li><a href="<?php echo get_post_meta($post->ID, "gallery-url", $single = true); ?>" title="Link to <?php the_title(); ?>"> <img src="<?php echo get_post_meta($post->ID, "image", $single = true); ?>" alt="<?php the_title(); ?>" /></a></li> <?php endforeach; ?> </ul>
That’s it! The most important item you may want to change for your own custom field is the line : AND wpostmeta.meta_key = 'gallery-url'
. Where you would change the text in bold to match your own custom field value.
Update:
Check out Austin from PressedWords comment below.
With his great advise I was able to figure out why all my attempts to use the query_post weren’t working. it came down to this line of code: <?php echo get_post_meta($post->ID, "gallery-url", $single = true); ?>
, that was what I had in my code, and the $post->ID
is the reason my code would not echo or print the custom field’s value. Solution? replace $post->ID
with get_the_ID()
. HA, so simple.

Thank You! A Lot!
This really helped me!
BTW How did you make the archives widget to show the dates separately into two columns?
Thank you.

Austin,
I just found this post while checking out my ad. You might want to try this little widget with Widgetifyr.com and see what added features it gives you. In the instant version you’d get all the theme complaint pre and post calls. You can all the nice control panel stuff like a title and description.
I was thinking about just doing it for you and pasting it here, but I wasn’t sure how code would be translated in a comment.
Thanks
Glenn
