Removing wp_head() elements (rel=’start’, etc.)

Richard — Tue, 08 Sep 2009 16:37:36 +0000

In customising Wordpress you may find a need to occasionally remove or add to the Link elements that Wordpress automatically outputs in the function call wp_head(). I’ve recently had a need to remove the rel=’prev’ and rel=’next’ link elements and in trying to avoid customising the core Wordpress functions the following solutions works.

Ensure you have a functions.php file in your theme directory that you are using. If not create the file and edit the file. The following lines will help remove select lines from your wp_head() function:
remove_action( 'wp_head', 'feed_links_extra', 3 ); // Removes the links to the extra feeds such as category feeds remove_action( 'wp_head', 'feed_links', 2 ); // Removes links to the general feeds: Post and Comment Feed remove_action( 'wp_head', 'rsd_link'); // Removes the link to the Really Simple Discovery service endpoint, EditURI link remove_action( 'wp_head', 'wlwmanifest_link'); // Removes the link to the Windows Live Writer manifest file. remove_action( 'wp_head', 'index_rel_link'); // Removes the index link remove_action( 'wp_head', 'parent_post_rel_link'); // Removes the prev link remove_action( 'wp_head', 'start_post_rel_link'); // Removes the start link remove_action( 'wp_head', 'adjacent_posts_rel_link'); // Removes the relational links for the posts adjacent to the current post. remove_action( 'wp_head', 'wp_generator'); // Removes the Wordpress version i.e. - WordPress 2.8.4
Don’t remove these items unless you have a need to. The Wordpress generator removal could be useful if you are not religiously upgrading your Wordpress install as it helps hide the WP version from potential hackers to a certain degree.

RGB to HEX Converter

Working with CSS I am constantly trying to convert RGB values from Photoshop to their hex equivalent. There is probably a setting in PhotoShop that I have missed, but the following small form will quickly convert RGB values to the HEX equivalent. You can then use these values in CSS with # at the beginning.

Determine URL of an ImagePlaceholder

Richard — Thu, 27 Nov 2008 06:01:32 +0000

I came across a problem recently whereby I wanted to determine the MCMS URL of an image stored in the MCMS Resource gallery. The script had several image placeholders, some of which may of had images bound to them.

My requirements involved determining the URL of any given image and then to use this in some CSS styling. Faced with this scenario the following code should help:

//Setup placeholder object and string for URL Placeholder pl; string imgSrcUrl = "";


//setup default CSS string

string FeatureCSS = ””;

pl = ImageX.BoundPlaceholder;//get the bound placeholder for this control if (pl!=null){//test the placholder is not null imgSrcUrl = ((ImagePlaceholder)pl).Src ;//get the source url from the placholder if (imgSrcUrl!=null && imgSrcUrl!=”"){ FeatureCSS = “”; } else doSomethingElse(); } else doSomethingElse();
