Custom Content Within Post

    I’m trying to automatically add a relevant hyperlinked logo to a post based on how the post is categorized. For example if the post is about Coca-Cola, the Coke logo should be displayed and linked to the Coke website.

    I thought I would create a new content type for all logos/links. Is there a way that I can associate these new pieces of content with posts based on categories and pull them into the posts in my template? Thanks!

    When you say a new content type, do you mean you’ll have a taxonomy or category that stores this information somewhere?

    From what I see, the easiest way to do this would be to build an array like this:

    <pre>
<?php
// Paste this code in functions.php
// coke pepse sprite are shown like slugs here, you can also just use IDs (that would be easier)

$category_extra_info = array(
	'coke' => array(
			'link' => 'http://domain.com',
			'image' => 'http://domain.com/logo.png'
			),
	'pepsi' => array(
			'link' => 'http://domain2.com',
			'image' => 'http://domain2.com/logo.png'
			),
	'sprite' => array(
			'link' => 'http://domain3.com',
			'image' => 'http://domain3.com/logo.png'
			),
);

// And then use it like this anywhere in template
echo '<a href="' . $category_extra_info['coke']['link'] . '" rel="nofollow"><img src="' . $category_extra_info['coke']['image'] . '" alt="logo" /></a>';
?>
</pre>

    If you want to autoreplace words and make things even more dynamic, you can do it this way:

    <?php
// Paste this code in functions.php
// coke pepse sprite are shown like slugs here, you can also just use IDs (that would be easier)

$category_extra_info = array(
        'coke' => array(
                        'link' => 'http://domain.com',
                        'image' => 'http://domain.com/logo.png'
                        ),
        'pepsi' => array(
                        'link' => 'http://domain2.com',
                        'image' => 'http://domain2.com/logo.png'
                        ),
        'sprite' => array(
                        'link' => 'http://domain3.com',
                        'image' => 'http://domain3.com/logo.png'
                        ),
);

function category_extra_info_parsing( $text ){
        // make it accessible
        global $category_extra_info;

        // loop and build the $replace array
        foreach ( $category_extra_info as $cat => $info ) {
                $replace[ $cat ] = '<a href="' . $category_extra_info['coke']['link'] . '">' . $cat . '</a>';
        }

        // replace words now
        $text = str_replace(array_keys($replace), $replace, $text);

        //return modified content
        return $text;
}

add_filter('the_content', 'category_extra_info_parsing');

// add_filter('the_excerpt', 'category_extra_info_parsing'); // Uncomment this line for parsing the category words

// And then use it like this in your template
// echo '<a href="' . $category_extra_info['coke']['link'] . '"><img src="' . $category_extra_info['coke']['image'] . '" alt="logo" /></a>';
