Thematic WordPress Theme Toolbox: 10 extremely useful hooks

If you’re looking for a tutorial on how to create a Thematic child theme, you should read this post.

Add a favicon

A favicon is a small image displayed by modern web browsers. It is a must have for all websites, because it allows your visitors to quickly visualize your site among others when they have lots of browser tabs open at the same time.
This handy code will add your favicon to your theme. Make sure a favicon.png file is in your child theme images directory, and then paste the code in your functions.php file:

function childtheme_favicon() { ?>
	<link rel="shortcut icon" href="<?php echo bloginfo('stylesheet_directory') ?>/images/favicon.png" />
<?php }
add_action('wp_head', 'childtheme_favicon');

Add an Internet Explorer specific stylesheet

Who doesn’t hate Internet Explorer? Unfortunately, most clients will require developers to make their site IE-compliant. And the best way to do so is to use some conditional comments and a dedicated stylesheet.
Create a file named ie.css in your child theme directory, and then insert the following code in your functions.php file:

function childtheme_ie_style() { ?>
	<!--[if IE]>
		<link rel="stylesheet" type="text/css" href="http://www.webdevcat.com/wp-content/themes/webdevcat/ie.css" />
	<![endif]-->
<?php }
add_action('wp_head', 'childtheme_ie_style');

Modify Doctype

By default, Thematic outputs a XHTML 1.0 transitional doctype. If for some reason, you prefer using another kind of doctype, pasting the code below in your functions.php will do the trick.

function childtheme_create_doctype($content) {
 $content = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">';
 $content .= "\n";
 $content .= '<html xmlns="http://www.w3.org/1999/xhtml"';
 return $content;
}
add_filter('thematic_create_doctype', 'childtheme_create_doctype');

Use Feedburner RSS feeds

Feedburner is very popular among bloggers. If you want to replace default rss feeds by feedburner feeds in Thematic, this code is for you.

function childtheme_rssfeeds($content) {
	$content = "\t";
	$content .= "<link rel=\"alternate\" type=\"application/rss+xml\" href=\"";
	$content .= "http://feeds2.feedburner.com/Catswhocode";
	$content .= "\" title=\"";
	$content .= wp_specialchars(get_bloginfo('name'), 1);
	$content .= " " . __('RSS feed', 'thematic');
	$content .= "\" />";
	$content .= "\n";
	return $content;
}
add_filter('thematic_rss', 'childtheme_rssfeeds');

Add Google Analytics code to your Thematic child theme

Google Analytics is another free and very useful service. In order to allow GA to collect your visitor information and create your stats, you have to insert a small piece of Javascript on your footer.php file.
Insert this code in your functions.php file, save it, and you’re done. Of course, don’t forget to replace the Google Analytics code with your own!

function ga(){ ?>
	<script type="text/javascript">
	var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
	document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
	</script>
	<script type="text/javascript">
	try {
	var pageTracker = _gat._getTracker("UA-XXXXX-10");
	pageTracker._trackPageview();
	} catch(err) {}</script>
<?php }
add_action('wp_footer', 'ga');

Modify Thematic footer credit

If you’re building a Thematic child theme for a client, you may want to insert your credit link in the footer text. The following code will do it. Don’t forget to give credit to Ian Stewart for his awesome work on the Thematic theme framework!

function my_footer($thm_footertext) {
	$thm_footertext = 'Copyright &copy; 2010 Jean-Baptiste Jung. <a href="http://www.webdevcat.com">WebDevCat.com</a> is obviously powered by <a href="http://www.wordpress.org">WordPress</a> &amp; the <a href="http://www.themeshaper.com/thematic">Thematic Theme framework</a>.';
	return $thm_footertext;
}
add_filter('thematic_footertext', 'my_footer');

Display Thematic menu above header

Want to have your navigation menu above your site header? That’s not a problem. This code will remove the menu from below the header and then put it above it.

function remove_thematic_actions() {
    remove_action('thematic_header','thematic_access',9);
    add_action('thematic_aboveheader','search_access',9);
}
add_action('wp','remove_thematic_actions');

Change “more” link text

Thematic “Read More” link displays Read More » by default. The following code allow you to change the “Read More” text.

function childtheme_more_text($content) {
	$content = 'Click to read the rest!';
	return $content;
}
add_filter('more_text', 'childtheme_more_text');

Change gravatar size in Thematic comments

By default, Thematic displays 35px*35px gravatars. If you want to change this size, no problem: Just paste this code in, as usual, your beloved functions.php file.

function childtheme_avatarsize() {
    return '56';
}
add_action( 'avatar_size', 'childtheme_avatarsize' );

Remove Thematic menu on specific page template

If you want to make a squeeze page on your site or blog using Thematic, that’s quite easy: You only have to create a page template and remove the menu. To do so, just paste the code below in your functions.php file.
Don’t forget to set your page template name on line 2.

function remove_access() {
    if (is_page_template('affiliate.php')) {
        remove_action('thematic_header','thematic_access',9);
    }

add_action('wp_head','remove_access');
}
