I had created an Album, which is a container for mutiple Galleries. Simple enough. But then, once you had selected a Gallery, I wanted to display the Gallery description on the Gallery page above the thumbnails.

In the Manage gallery section you can type a description, but it didn’t seem there was any way to display that on the actual website.

So if you need to, open the file gallery.php which is inside the plugins directory, nextgen-gallery/view/gallery.php

Next, above the line
<div class="ngg-galleryoverview" id="ngg-gallery-<?php echo $gallery->ID ?>">
add this:
<h2><?php echo $gallery->title; ?></h2>
<p class="gallery-desc"><?php echo nl2br($gallery->description); ?></p>

This will give you an H2 with the Gallery Title, and then the description below it.

1. At first I kept getting a “permission denied” error – you’ll need to search the httpd.conf file for the <Directory /> container and get rid of Deny from all. (Or at least comment it out, anyway.)
2. The mod-rewrite wouldn’t work. Two steps to fix this:
   1. Search httpd.conf for mod_rewrite and uncomment the LoadModule line.
   2. Search for AllowOverride. There should be two instances where you need to change None to All. (Source)

Now I can get back to work!

We have come so far with browsers, but unfortunately most email clients are, well, a long way behind. If you have ever tested an HTML email in a few different clients you’ll know the frustration.
Yesterday’s launch of the Email Standards Project hopes to remedy this situation. Some people love it, some hate it, but HTML email is here to stay. And if we could have the proper standards support in email clients then it’s probably fair to say that a lot of those opposed would change their mind.

We have a long way to go, but at least now we have a vehicle!

I’m not a big fan. They’re often hard to read even for someone with reasonably normal vision.

“Is that a zero or the letter O?”

“Upper case C or lower case c?”

Others have suggested some sort of simple logic question, like asking “What’s 1+1″ and having the user enter a ‘2′ in a text box.

That might be better, but it also requires some thought.

So I noticed that on Slideshare they prefix a captcha device with the question, “Are you human?”

And it got me thinking, can bots deal with radio buttons? Can we ask a question like this?

<form>
Are you human?<br />
<input type="radio" name="Human"
	value="No" checked="checked" />
	No, I'm a spam robot<br />
<input type="radio" name="Human"
	value="Yes" />
	Yes, I am human <br />
</form>
</body>
</html>

Download this code: human_form.htm

I must admit I haven’t done any research, but I’m thinking:

1. If a bot doesn’t understand radio buttons it will skip the question and fail
2. If it does understand radio buttons, it will probably choose the first option and fail
3. It’s an extremely simple question for a human to answer and should be completely accessible.

Point 2 is probably the most contentious. I’m making a big assumption there.

Has anyone else tried this? Can anyone spot any obvious disadvantages?

EasyPHP. Worked straight away for me without having to do anything!

Any if you do need to customise it, a little interface makes that pretty simple, too.

If you have to create HTML email, you’ll be pleased to know that Outlook 2007 won’t use IE as it’s rendering engine any more. It uses… wait for it… Word! And we all know how good Word is at rendering and creating HTML! (Not!!!)

So instead of getting improved standards support in the next version of Outlook, we take about 20 steps backward instead.

Sheesh… what are they thinking?

1. PING
   If you need to check your connection to something, this is the basic check. You can either ping a name or an IP address.
   ping www.sitename.com
   or
   ping 127.0.0.1
   are both valid. If you ping a name, you can also see what IP address that name resolves to.
2. TRACERT
   This will trace the route to another computer. Again, you can use a name or an IP address.
   tracert www.sitename.com
3. SHUTDOWN
   This one will shut the computer down. (Pretty obvious, hey!) Really handy to put at the end of a batch file that does a backup or something similar. Heaps of switches, so type shutdown /? to display all the options available.
4. IPCONFIG 
   Displays the IP address of your computer, plus the address of your gateway (eg your ADSL modem or the computer that’s actually connected to the internet).
5. XCOPY
   Great for quick and easy batch backups. Check xcopy /? for all options available.

That’s 5 that I use a fair bit – got any others?

If you’re really bored, here’s Microsoft’s A-Z Reference.

So – if you move a page and want it to be followed by a search engine (and keep it’s pagerank etc), open up your htaccess file and enter (all on one line):

redirect 301 /olddir/oldpage.html http://www.newsite.com.au/newdir/newpage.html

Or if you’re shifting a whole directory (again, all on one line):

redirect 301 /olddir/ http://www.newsite.com.au/newdir/

The 301 code says “moved permanently”, so don’t use it for temporary redirections. Obviously this htaccess stuff is for linux servers, if you’re on Windows then there’s a different way… But you’ll have to find that somewhere else!

This snippet uses jQuery – an excellent little piece of Javascript that makes this sort of trickery relatively simple.

Firstly, have a look at the basic syntax here: jquery.com/docs/ajax

A couple of things that I stumbled on:

1. Content loaded via the .load call doesn’t have any event handlers attached, so in the Callback function you need to use .find() to look for any elements you want to assign events to.
2. Getting the ID of the element clicked ended up being pretty simple: this.id
3. Getting the value of a form field involves a simple walk around the DOM – as the form isn’t actually “Submitted” – use document.GetElementById(”fieldID”).value

Then you should end up with something more-or-less like this:

<script type="text/javascript">
$(document).ready(function(){ // Gets everything set up on page load
	$("#searchbutton").click(function(){
	  // Search button has been clicked - let's do some AJAX, baby!
	  $("#animal_table").load("/includes/catalogue/getlots.php",{
		start: "0", // pass static values
		year: "<?php echo $thispage['year']; ?>", // pass PHP variables
		sire_id: document.getElementById("sire_id").value
		// or pass element values from a form field or similar
		},function(){
	      // search for new "a" elements after .load 
		  // is called so loaded stuff can be clicked,
		  // as stuff loaded this way has no event handlers attached
		  $("#animal_table").find("a").click(function(){
			$("#animal_detail").load("/includes/catalogue/showdetail.php",{
			  lot_id: this.id // pass the ID of whatever link is clicked
			});
			return false; // so the link doesn't actually load a new page
		  });
		});
	});
});
</script>
