Fixing Zen Cart’s Tax Miscalculation When Using a Coupon

I was recently alerted to an error in Zen Cart by a client where the tax was being miscalculated when using a coupon. Here’s the fix. Around line 240 in /store/includes/modules/order_total/ot_coupon.php Remove these lines: //$od_amount[$tax_desc] += (($products[$j][‘final_price’] * $products[$j][‘quantity’]) * $tax_rate)/100 * $ratio; //$od_amount[$tax_desc] += round(((($products[$j][‘final_price’] * $products[$j][‘quantity’]) * $tax_rate) + .5)/100 * $ratio, 2); …

It’s always a good idea to protect yourself from all sorts of possible malicious attempts by users (or even mistakes by misinformed users). Here we look at taking a string of text (a filename) containing characters that are generally speaking unsafe. Here’s a simple way to clean-up filenames (or other text input) using PHP – …

Amberjack Media, RevealCMS

It’s official – I’m now Amberjack Media (amberjackmedia.com). The papers from the city just arrived, but the process with officially registering the DBA with the county is not yet complete. I have the domain, but it’s not yet set-up with any hosting space just yet. On another note, I’ve named the CMS i’m working on: …

Cool Exposé trick in Mac OS X

When pressing F10 (or Ctrl-F10) to show a program’s open windows, you can press Cmd-Tab to cycle through all running apps, showing the icons across the screen as the normal Cmd-Tab does. You can also scroll through running apps in Exposé by pressing Cmd-` (back tick), but without the icons. Apparently this will also switch …

Install PHP mb_string in Fedora

Q: How do you install the mb_string PHP extension in Fedora? A: % sudo yum install php-mbstring It’s really painless. Answer a few y/n questions (probably want to answer “yes” to all of them), restart apache, and you’re done! Also see my recent post on adding gd support to PHP in Fedora.

My company name?

Now that I’m officially an independent contractor/developer, I thought it would be good to have a company name – something that sounds like a good Web 2.0 outfit. Likewise my CMS will need one as well, though I already have a few ideas… If you have a good idea, let me know. If I like …

Smart template plugins with Smarty

Smarty is becoming more and more popular in the PHP community lately, especially as developers are moving away from mixing business and display logic in the same scripts and towards a cleaner MVC design pattern implementations.

I venture towards Ruby on Rails

I now own my own Ruby on Rails book, a kind gift from my good friend Doug. I can’t get started on it right away due to certain looming deadlines called a content management system, written in PHP. I am, by the way, trying to come-up with name for it, if you have any ideas! …
