Fri, 12 Aug 2011 19:38:19 UTC

WordPress allows you to embed videos so easily using oEmbed. You can easily add videos to your post just pasting their URL to your post. WordPress handles all the object and embed HTML for you. But this code is missing wmode parameter which is necessary for CSS z-index to work. Here I will show you how to filter the HTML for the embedded video and add this parameter so easily. For this we will use the oembed_dataparse filter which is run when a user adds a video to the post. Place the following code in your theme's functions.php file:

(PHP) Custom Fields - SEO Your Title Tag - paulgrenwood

Wed, 23 Sep 2009 16:05:36 UTC

Search Engine Optimisation, or SEO is something that a lot of bloggers get obsessed about, whilst others think itâ€™s a load of rubbish. Iâ€™m halfway between the two â€“ whilst I believe that you can change certain things to better SEO your content, such as adding H1, H2 etc tags in the appropriate places, I personally donâ€™t think you should get too carried away with it. One of the things you can do though is change your title tag, and this custom field trick will let you set a custom field and itâ€™ll appear as your title tag. Add the code below to your header.php file:

(PHP) Custom Fields - Display a thumbnail (and auto resize it) - paulgrenwood

Wed, 23 Sep 2009 16:04:25 UTC

Whilst there are a number of ways of displaying thumbnails, this is still my favourite (even if it does require the most work!).

This is the image that will be displayed if no custom field is displayed. Then, for every thumbnail, youâ€™ll need to create it in Photoshop and upload it to your blog. Next, create a custom field â€˜Imageâ€™ with the path of the image as the value of the custom field. Now for the code:

All youâ€™ve got to do for this trick to work is create a custom field â€˜Seriesâ€™ with a link to each other post in the series. Each post must be a seperate custom field. Then, use the code below to display all the other posts in the same series!
