Ping Google/Bing/Ask with Your Sitemap – PHP

By admin | Published May 9, 2012 at 9:53 pm

Google, Bing, Ask.com, and Yahoo (they stopped their ping service) all have services where you can send the url of your sitemap in a http request and get it added to the crawl queue. You can automate this process by using this PHP function, which will ping all 3 given your sitemaps’ urls. Here’s the function (it’s kind of long so I’m putting it after the jump):

Custom Nav Menu Walker Function to Add Classes

By admin | Published May 9, 2012 at 4:31 pm

If you’re trying to make a fancy navigation menu with CSS, you might have found the default ids/classes applied by WordPress to the ul and li elements to be quite lacking. However, you can fix that by adding a custom walker function to add your own classes.

The custom nav walker function I made below will add the following CSS classes:

  • .main-menu to top menu
  • .sub-menu to menus inside the main-menu
  • .menu-item to all li’s
  • .main-menu-item to all li’s in the main menu
  • .sub-menu-item to all li’s in a sub-menu
  • .sub-sub-menu to all menus inside a sub-menu
  • .menu-even/.menu-odd for ul’s (alternating)
  • .menu-depth-# to tell you how deep each menu is
  • .menu-item-even/ .menu-item-odd
  • .menu-item-depth-# to tell you which level menu the li is in
  • .menu-link to links

 

This should make styling your Nav Menus MUCH simpler.

You call the function by suppling the name in the args when you call wp_nav_menu. So for example, to enable our walker, we would call the menu with this: Continue reading »

Patent Bar Exam Stuff

By admin | Published May 6, 2012 at 8:38 am

I’m taking the patent bar and I figured I’d write up my study stuff here instead of some text editor where it will be lost forever. So forgive the flood of dry, legal, patent posts for the next few weeks, (on second thought, I think I’ll keep it all in one multipage, megapost for now. On third thought, this would go a lot smoother (formatting and interlinking wise) on the wiki.)

And if you’re a prospective USPTO exam taker, I hope you find some of this helpful! Feedback on my misunderstandings would be more appreciated than ever!

MediaWiki is Live

By admin | Published April 28, 2012 at 10:25 am

I’ve got the MediaWiki up and running. I’ll be using it most for man pages for my plugins/themes since WordPress isn’t actually very well suited for that kind of stuff.

Forcing W3C Compliance on WordPress… Elegantly

By admin | Published April 28, 2012 at 4:26 am

WordPress is generally pretty compliant, but there’s a couple sticking points that can prevent your blog from being fully validated. I guess there’s a bit of controversy behind this. One reason is that attributes like role help blind people use the internet via screen-readers. So does this mean all W3C compliant websites hate the blind? No, it just means they prefer the warm, fuzzy feeling of knowing their code is up to spec.

I developed a filter function (as part of the process of building my first WordPress theme) that strips out any attributes that do not conform to the W3C XHTML 1.0 Transitional specification. It shouldn’t affect the normal functionality of the blog, but it might make it harder for disabled people to enjoy your posts.

Summary of Changes

Here is a summary of the changes it makes:

  • Removes role="search" from the default search widget
  • Removes aria-require="true" into comments textarea

How to Execute PHP Code from a Variable or Textbox

By admin | Published April 27, 2012 at 3:54 am

I’ve been working on adding options to a WordPress theme and I never had to execute user inputted PHP code before. Turns out it’s actually pretty easy. You just have to use the eval() function. Here’s an example:

$code = 'phpinfo();' // code in string form
eval( $code );

That’s it! Thanks to Roshan Bhattarai for answering my Google inquiry.

Note: Official WordPress themes do not allow you to run code through eval(), if you’re planning on getting it into the repo. The second best solution is just write to a PHP file then include it as needed.
