WordPress custom theme options

01 Sep 2010
by Dejan Jacimovic

As I was surfing the net I have stumbled upon Jeffrey Way’s theme options page. Basic and simple option page that let’s you download the code in order to start making your own options page on your custom theme. If you are into WordPress – one day you will need it – so better don’t forget this link.

This snippet shows copy of Jeffrey Way’s admin menu for WordPress theme options taken from GitHub. It will work if you simply copy it in your theme functions.php file.

#theme-options-wrap {
	width: 700px;
	padding: 3em;
	background: white;
	background: -webkit-gradient(linear, left top, left bottom, from(#f4f2f2), color-stop(.2, white), color-stop(.8, #f4f2f2), to(white));
	border-top: 1px solid white;
}
 
#theme-options-wrap #icon-tools {
	position: relative;
	top: -10px;
}
#theme-options-wrap input, #theme-options-wrap textarea {
	padding: .7em;
}

After you apply both script and style – your custom theme options will look like options on the picture below. Have a lots of fun customizing it!
