Create a Windows Batch (.bat) File to Test Your Internet Connectivity

I have been having issues with my ISP‘s WiFi router, so I decided to create a batch file I could run as-needed to check internet connectivity.

@echo off
set "router="
set /p "router=Enter router IP address or press [ENTER] for default [%router%]: "
@ping %router% -n 1 | FIND "Reply"
@ping -n 1 | FIND "Reply"
@ping -n 1 | FIND "Reply"
echo Press any key to exit...
pause >nul

Save that as `ping.bat` and put in somewhere convenient. Then…

Organizing Images or Other Files with Hashed Folder Names

I finally decided to tackle a site that had over 20GB of images in a single folder. I won’t say who created this monster (whoops), but while moving the site to a new dedicated server, I decided it was time to remedy the situation.

The first issue is with anything you want to (graphically) process folders is limited greatly by the GUI and how much data needs to be processed for each request. This is why I decided a hashed folder naming convention would be the best approach. The folder names do not matter, just so long as there is reasonable grouping and/or separation.

How to Find Your Payeezy FirstData GGe4 Credentials for Payment Module Settings

My most common request for help stems from the following error…

Error 4025: Invalid credentials
The credentials supplied in the authorization request are invalid.

This error indicates you are using the wrong credentials for the transaction server selected in your payment module’s settings. It can also indicate FirstData has not enabled web transactions for your terminal. Continue reading

Additional Alert Email Does Not Work in OpenCart

Even though we are still finding bug in Open Cart, it is still a far cry better than what we’ve seen from 3.x by far.

You may have noticed the “Additional Alert Email” field simply will not save in your OpenCart “Store Settings” editor. This is a result of the OC devs renaming the input field in without changing the references everywhere else. Continue reading

SEO URLs for OpenCart Using a “web.config” File on Windows IIS Server

I always suggest Linux hosting for any OpenCart installations. The main OC developers either don’t know much about Windows IIS or neglect to include the necessary SEO URL configuration file for it to work.

This omission results in “not found” 404 (dead link) errors when you visit a page with an SEO URL assigned after enabling SEO URLs in your OpenCart store settings.

PHP Function to Sum or Concatenate Associative Array Values

Here is a quick function I created to merge multiple arrays and sum or concatenate the values thereof. If the values are numeric they will be added together (sum). Otherwise the values will be appended to each other (concatenation).

function arrayMergedSumConcat() {
	$out = array();

	$num_args = func_num_args();
	$arg_list = func_get_args();
	for ($i = 0; $i < $num_args; $i++) { $in = $arg_list[$i]; foreach ($in as $key => $value) {
			if (isset($out[$key])) {
				if (is_numeric($in[$key]) && is_numeric($out[$key])) {
					$out[$key] += $in[$key];
				} else {
					$out[$key] .= $in[$key];
			} else {
				$out[$key] = $in[$key];
	return $out;

Add Hints to Custom Fields in Open Cart 2.x

We have published a new extension that allows you to add a “hint” for your custom field at Account and Address locations.

More details:

The name of a custom field is often not enough to inform a customer what the entry is for or the required format. This extension gives you an extra field to better describe the purpose and validation requirements for all of your custom fields. The field hint is displayed in all relevant guest and customer forms. See the images included on this page for examples.

CCleaner… loved by many, avoided by me (with good reason)

I have always been of the mindset, the more you add to a system to automate mundane tasks, the more you open yourself to exploits. I have had to deal with many workstations, servers, and personal computers that were previously maintained by other (less experienced) administrators that swear by the use of CCleaner, Defraggler, and Speccy (not linking intentionally, use Google if you want links to their software). I have always immediately removed them as one of my first clean-up tasks. Continue reading

Toggle Password Display in HTML5 with jQuery

Do you have  a password field that the user wants to be able to view at the click of a button? Here is the solution I came up with to handle that need…

The field…

<div class="input-group">
  <input type="password" name="password" value="P@$$w0rD" placeholder="Password" id="input-password" class="form-control" required>
  <span id="view-password" class="input-group-addon"><i class="fa fa-eye" aria-hidden="true"></i></span>

The javascript… Continue reading
