The problem was that The page I was developing had an <img> in it with the “src” attribute set blank.  When the document was fully loaded, javascript was in place to dynamically assign the “src”.  This worked perfectly fine in the pre-server-side-logic stage of development so it was an easy decision to begin debugging server-side logic.

The double execute happens when Firefox sees <img src=”" />.  Not knowing what source to assign, it sends a request (the second request) to the current path (again) for the image.  Therein lies the problem.  It’s interesting to note that Firefox is not to blame, as it’s following HTML specification.

Unfortunately, none of the three CSV formats that Excel outputs could be properly parsed as CSV. For example, accepted CSV standards state that values should be:

"value1","value2","escaped "" double quote", "value 3", "", "", "7th column"

But in Excel’s version of CSV, that would look like:

value1,value2,"escaped "" double quote",value 3,,,7th column

It’s terribly inconsistent in its use of double quotes, confusing the hell out of many CSV parsers.

The Solution:

CSV to XML Converter by Creativyst(R). It takes in CSV garbage and returns immaculate and clean XML. Then use your language-of-choice’s XML functions to work with the data.

For “move-item-forwards” functionality, the logic may look like:

move_item_up( index ){
  Store the element at index 3 to a temporary variable.
  Set the value of index 3 to the value of index 4.
  Set the value of index 4 to the temporary variable's value.
}

The “technique” comes into play now, when you have to do the “move-item-backwards” functionality.

Instead of:

move_item_back( 4 );

Simply use:

move_item_up( 3 );

Moving an item backwards in a list is the same as moving the previous item forwards. This technique is rather simple and perhaps painfully obvious to some, though it may be useful to others.

$arguments["PostFiles"] = array(
	"userfile" => array(
		"Data" => "This is just a plain text attachment file.",
		"Name" => "attachment.txt",
		"Content-Type" => "automatic/name",
	),
	"anotherfile" => array(
		"FileName" => "test_http_post.php",
		"Content-Type" => "automatic/name",
	)
);

So it’s actually pretty easy to send files. This class provides two methods, as we’ve seen in the example.

• userfile: The first example sends raw data and provides a filename
• anotherfile: The second example sends the file specified in FileName

The script was found at PHP Classes, a resource I regularly tap into.  You’ll discover that PHP Classes requires registration, but it’s free and you can disable any email notifications.  Also, don’t be turned off by the website’s aesthetics, they were apparently going for “functional”.  Hey, it worked for Craigslist.
