$this->form_validation->set_rules('discountGlobal', 'Global Discount', 'trim|integer|max_length[1]|xss_clean|prep_for_form|only_one_global_discount[]');

My custom callback is only_one_global_discount. I am not explicitly passing anything through to it. However, in the function I have in my MY_Form_validation.php file, I can access the $discountGlobal value:

public function only_one_global_discount($discountGlobal) {
$CI =& get_instance();
echo $discountGlobal;

You can also pass a second value, though. You would change your callback call to:

$this->form_validation->set_rules('discountGlobal', 'Global Discount', 'trim|integer|max_length[1]|xss_clean|prep_for_form|only_one_global_discount['.$test.']');

Where $test is the second value you want available to you in your function. The function call would then change to:

public function only_one_global_discount($discountGlobal, $test) {

And the value of $test would be available to you in the function. But what can you do if you need a third, fourth or even more values? My solution is to package up the variables you need in an array. Just passing through an array just gives me “Array” when using a print_r on it in my callback function. So, I used json_encode on the array before passing it through and then json_decode in my callback function. Viola! I have access to as many variables as I need.

JavaScript Errors Notifier

I would think accomplishing something like this would be fairly easy in a Safari extension but, after looking at the documentation, I don’t think there is a way to access messages in the Error Console. I see where one can log their own messages to go in there, but I didn’t see where one can actually read messages that Safari puts into there. I was looking at the documentation here:

I am going to have to look for a resource where I can ask someone if this is possible. Another potential extension I was thinking about was an image overlay where a web developer could load in a comp above their webpage for comparison and adjust the opacity and position of the comp. This seems doable and I don’t see an existing one for Safari. There are ones for Chrome and Firefox but none of them seem to work all that great (at least on my Mac with the most up-to-date version of Chrome). The best I have found so far is:

I think my first project, though, needs to be a redo of a site I built and abandoned, Dog Walk Spot. I am trying to figure out now if I should build it totally custom in CodeIgniter or make it a customized WordPress site. Since I want to have advanced searches and sorting on a custom data type (a walking location) I was leaning toward CodeIgniter. I know that I can use Custom Post Types in WordPress to add the fields I would want but I am unsure how flexible it would be in allowing sorting and advanced searching on criteria for those fields.

How would President Romney handle the issue of people not being able to get insured because of pre-existing conditions? When he was on the Tonight Show, Romney said:

Well, if they are 45 years old and they show up and say I want insurance because I have heart disease, it’s like, ‘Hey guys. We can’t play the game like that. You’ve got to get insurance when you are well and then if you get ill, you are going to be covered. [...]

So what is he saying here? He doesn’t want the government to have a mandate to compel people to purchase insurance. But he’s saying the only way to be guaranteed insurance is if you’ve kept it current since before you were 45 years old (why 45 years old?) So, you’re free to not get insurance but what happens to this irresponsible 45 year old with heart disease? What is the logical next step? We saddle the person with a health care debt that they have no hope of ever paying? Or, as some enthusiastic Republican debate attendees would want, do we “let him die?” What is the alternative?

As far as I can tell, there is absolutely no Republican plan for dealing with banks that are too big to fail and to address possibly risky financial tools like Credit Default Swaps that partially caused the financial sector meltdown in 2008. Their solution seems to be to roll back any and all regulations. And, I guess if big losses happen in the future (see what just happened at JP Morgan) and a large bank gets into trouble we… what? Let it fail and drag down the economy? Have another bailout?

From everything I can see, the Republicans seem to be running on a continuation of George W. Bush’s policies – more tax cuts geared toward the wealthy, rolling back any regulations, cutting social programs and attacking organized labor.

It isn’t the most playable but it is really neat. I had some fun using Firebug in Firefox to explore the elements in the game and to tweak the CSS on individual elements. For example, I found that the Game Over graphic is a hidden div that I could click off the display: none rule, set a higher z-index and display over the game screen during the game. I was also peeking at the Javascript files for the game like:

Very neat stuff!

This allows you to see the results in a tool like Firefox’s Firebug while testing on a local development server. It is much nicer than running tests and coming back hours later only to find that there was an error in your code. I am not sure when this tool was made available, but I wish I knew about it earlier.
