<p>This plugin will display a given number of random blogroll categories to show.<br />
It will show all the links in those categories.</p>
<h3>Usage</h3>
<p>Unless you’ve changed some defaults, your blogroll is most likely displayed by<br />
the following line of code in wp-content/themes/[your theme]/sidebar.php:
    </p>
<p>The simplest way to display a random category is just by replacing that line<br />
with a call to blogroll_random_category:
    </p>
<p>If you want to include a link to the whole blogroll, you can create a page in<br />
wordpress using the links template. Note the permalink. If you’ve already got a<br />
list of your pages in the sidebar, you’re in business. Otherwise you can add one<br />
with the following line of code:<br />
    <a href="[your permalink]" rel="nofollow ugc">See complete blogroll</a></p>
<p>If your blogroll is not set to be categorized, or if there is only one category,<br />
it will return the whole thing untouched.</p>
<h3>Advanced</h3>
<h3>Showing multiple categories</h3>
<p>If you want multiple categories returned, you can send the function that number.<br />
For example:</p>
<p>will return 5 randomized categories. If you only have 4 categories, it will<br />
return all of them in a random order.</p>
<h3>Retaining arguments sent to wp_list_bookmarks</h3>
<p>If you’re sending arguments to wp_list_bookmarks, you can send those to<br />
blogroll_random_category and it will pass them along to wp_list bookmarks. In<br />
this example, we’re showing all categories except #23:
    </p>
<p>The change below will show five random categories, none of which will be #23. If<br />
you only have four categories, this will return the three that are not #23:
    </p>
<h3>To show one category all the time and the rest randomize the rest</h3>
<p>In the sidebar you can explicitly call that category. When only one category is<br />
selected, this plugin knows to return it as it is. Any subsequent calls to<br />
blogroll_random_category ought to be instructed to exclude it in order to avoid<br />
the possibility that it happens to be randomly selected:</p>
<pre><code><?php wp_list_bookmarks('category=23'); ?>
<?php blogroll_random_category(5, 'exclude_category=23'); ?><h3>1.0</h3>* The first version.<h3>1.5</h3>* Whereas this plugin previously altered the behavior of wp_list_bookmarks in a
</code></pre>
<p>way that made it impossible to see the whole blogroll. Now it uses a separate<br />
  function call so that in some instances you can see random categories, but in<br />
  others you can see the whole blogroll.<br />
* Now possible to return multiple random categories without separate function<br />
  calls, thus eliminiating the possibility that two of the random categories<br />
  will be the same.</p>
<h3>1.5.1</h3>
<ul>
<li>The leading closing li tag was not actually getting trimmed off due to<br />
bad copying and pasting. That has been resolved.</li>
</ul>
<h3>A personal request</h3>
<p>If you use/enjoy this plugin, I’d love to hear from you. You’re under no<br />
obligation, but I’d enjoy knowing that somebody out there is enjoying my work.<br />
Promptly returning e-mail is not my strong suit, so you may never get the<br />
courtesy of a reply, but you can rest assured that I appreciated your effort.</p>

<p>This plugin allows users to display their WordPress links by category through custom fields.</p>
<p>The following gives a step-by-step setup overview:</p>
<ol>
<li>Enable the plugin (check the installation tab)</li>
<li>Go to the page/post where you’d like to place your links/blogroll</li>
<li>Make sure that Custom Fields are visible (on the edit page or post page click on the “Screen Options” in the top right and make sure “Custom Fields” is checked off)</li>
<li>Under CUstom fields click on the enter new link</li>
<li>Enter an ID in the “Name” field – the plugin uses the ID “display_links” as a default</li>
<li>Enter the category name of the links you’d like to display in the “Value” field</li>
<li>Click on the “Add Custom Field” button</li>
<li>Enter the following shortcode into the post content area or the widget area you prefer: <code>[links_by_cat field_id="(ID previously entered in Name field goes here)"]</code>
<ul>
<li>Note that if you used “display_links” in the Name field, you do not need to enter the “field_id” parameter in the shortcode and can simply do: <code>[links_by_cat]</code></li>
</ul>
</li>
</ol>
<p>The shortcode also supports many other parameters for ordering and structuring your links. All parameters on the list (except “category”) found on the following page are available: https://codex.wordpress.org/Template_Tags/wp_list_bookmarks#Parameters</p>
<p>Other parameter example:</p>
<pre><code>[links_by_cat orderby="rating"] -- This is an example using the orderby parameter from the list. The links will now be ordered by their rating.
</code></pre>
<h4>Added in 1.0.1:</h4>
<p>The ability to display all categories has been added to the shortcode. Simply add:<br />
    [links_by_cat display_all]</p>
<p>Many bug fixes have also been introduced in version 1.0.1 as well, so please upgrade.</p>
<p>Currently, only one category is supported per Custom Field entry; however, I am looking to update the plugin soon so that it supports multiple categories.</p>
