If anyone that has server configuration knowledge and has tried to configure a server with Plesk installed, they probably had to go through a learning curve to get everything strait. Here is what I learned:

Just a quick note to say AJAX can be tricky and difficult to debug on occasion.

So, one day I found a need to have free shipping “per product” for CRE Loaded/OSCommerce.  First I search for it and found a couple candidates that seemed like they would do the job.

So, what a day today has been!  Usually when you think of installing SSL certificates (if you have installed them before) you think it will take you no more than an hour to set the whole thing up, right?  Well, not when it involves CPanel/WHM and wildcard certificates!

I really needed to get a list of files, recursively, from a rather large directory intensive web site sorted by the last modified date and I did not want to go through each directory searching for them by hand.  The idea was to get the last modified file in hope that I would find a file that contained a critical update for another web site with the same program.  After a couple hours of searching for and understanding the syntax involved, here is the Linux command that did the job.

find ./ -name “*.php” -type f -printf “%TY-%Tm-%Td %TT %h/%f \n” | sort -rb | head -5

So what we are doing is trying to find a file with a .php extension searching from the current directory we are in, recursively.  We are telling the command that it is a file type and sorting it in reverse order to show 5 in the list of files returned.  We would like to get the results in a formatted way, so we are displaying the date first then the file name.  Example output:

2009-08-31 15:14:38 ./admin/functions/email.php
2009-06-07 13:08:20 ./admin/config.php
2009-03-07 09:28:03 ./admin/inc.php

That’s it. Hope someone finds this useful!

As you may have guessed, I am writing this because there is an issue with using SimpleXML and Session variables in conjunction with each other.  Sessions apparently do not know how to handle object resource values that the SimpleXML engine generates.  If you attempt to assign a Session variable to a SimpleXML object value you will get an error similar to this:

Warning: session_start() [function.session-start]: Node no longer exists

Here is an example of assigning the Session variable the “wrong way” (from Authorize.net CIM API):

$_SESSION['profileid'] = $this->results->customerProfileId;

And here is the correct way to assign the Session variable:

$_SESSION['profileid'] = (int)$this->results->customerProfileId;

If the expected data type of the object value is to be a string use (string)

That’s about it for now . . .

I have been using pages to hold content in Wordpress templates for some time now.  The problem I have with it is that every time I need to perform such an action I cannot remember how to do it nor where I have done it before.

Yep, I finally got around to adding a LinkedIn company profile.  Check it out.

When setting a field in a MySQL database to be NULL by default you may run into NULL values in your dataset when querying the database.  You cannot simply check if a variable is set using the isset() function in PHP because it returns false for NULL values.  To remedy this issue you can use the array_key_exists(‘key’, $dataset) to check if the key exists in the array.

Good to know!
