While working on a new site design, I found an interesting bug in WordPress 2.7. I created two new pages to use as “Front page displays”, one called Blog and one called Home. To create the pages, I clicked on Pages > Add New, entered a Title and clicked Publish.

I then went to my Reading Settings (Settings > Reading) and set the static Front and Posts page to the pages I just created. Going back to my site, I tested out the new static pages only to find they didn’t work.

During the time that I’ve been using jQuery (about a year now), I’ve run into three fairly significant browser issues. Between IE, Firefox, Safari, and Opera, Firefox is the only browser that I have yet to experience any issues with (related to jQuery, of course).

In jQuery 1.2.1, when using the $.ajax function with cache: false, jQuery appends a parameter with the current timestamp to the URL. This parameter makes the URL unique and therefore prevents subsequent request from being retrieved from the browser cache.

However, the code that adds this ‘no-cache’ parameter does not check to see if it already exists and so under certain circumstances you can end up with URL’s that look like:

http://mysite.com/file.html?_=1196716041523&_=1196716462963&_=1196716464245

It certainly makes the URL unique

I opened a ticket and submitted a patch, which was quickly optimized by a jQuery developer, davidserduke.

It’s nice to see a project with responsive, helpful developers.

In Struts 2.0.11, the s:submit tag with type=button does not render properly.

While working on a project using Struts 2, I was attempting to create a HTML button that looked something like:

<button type="button" class="button positive save">
    <img src="/images/tick.png" alt="Save"> Save
</button>

I followed the Struts 2 Tag Reference for the submit tag and tried the following:

<s:submit type="button" cssClass="button positive save">
    <img src="/images/tick.png" alt="Save"> Save
</s:submit>

Instead of rendering like my example above, it looks like:

<img src="/images/tick.png" alt="Save"> Save
<button type="submit" id="test_0" value="Submit" class="button positive save">Submit</button>

Not exactly what I had in mind…

I stumbled upon a PHP framework called Kohana, which is based on CodeIgniter. I’ve used CI a bit in the past and thought I’d give Kohana a whirl. I downloaded the latest code and tried to run it on a Windows XP machine.

Well, when I brought up the site, I got an error:

Fatal error: Unable to locate the requested file, log.php in <system_path>/system/core/Kohana.php on line 408

After a lot of digging, I found that there was a glob() call that was not behaving correctly. I narrowed it down to what I believe to be a bug in PHP with the glob() function, using the GLOB_BRACE flag, and using a pattern that includes a colon (as in {c:/firstFolderToCheck,c:/secondFolderToCheck}).

Assuming it turns out to be valid, I’m surprised that it hasn’t been found/reported before…
