Count Down Closing Timer and dealing with DST in JavaScript

You can add these date prototypes to properly display the date and time in another location regardless of whether you are in DST or you or the destination observe DST

			Date.prototype.stdTimezoneOffset = function () {
				var jan = new Date(this.getFullYear(), 0, 1);
				var jul = new Date(this.getFullYear(), 6, 1);
				return Math.max(jan.getTimezoneOffset(), jul.getTimezoneOffset());
			}

			Date.prototype.isDSTNow = function () {
				return this.getTimezoneOffset() < this.stdTimezoneOffset();
			}

			Date.prototype.isDSTObserved = function () {
				var jan = new Date(this.getFullYear(), 0, 1);
				var jul = new Date(this.getFullYear(), 6, 1);
				return jan.getTimezoneOffset() != jul.getTimezoneOffset();
			}

			Date.prototype.couldBeDST = function () {
				var d = new Date();
				var month = d.getMonth();
				var day = d.getDate();
				var dow = d.getDay();
				var previousSunday = day - dow;
				// January, February, and December are out.
				if (month < 3 || month > 11) { return false; }
				// April throuh October is in.
				if (month > 3 && month < 11) { return true; } // In March, we are DST if our previous sunday was on or after the 8th. if (month == 3) { return previousSunday >= 8; }
				// In November we must be before the first Sunday to be DST.
				// That means the previous Sunday must be in the previous month
				// aka less than/before the 1st.
				return previousSunday < 1;
			}

Full Code
This example takes an hours array with unique IDs and TZ info about a location and uses the current information to update the appropriate on screen timer every 1 second.

 
jQuery( document ).ready(function($) {
	var now = new Date();

					splitHours = hourSet.split(',');
					var isoDate = new Date(currentTime.getTime() - (currentTime.getTimezoneOffset() * 60000)).toISOString();
					var open = new Date(isoDate.substring(0, 10) + ' ' + splitHours[0]);
					var close = new Date(isoDate.substring(0, 10) + ' ' + splitHours[1]);
					var offsetSec = ( offsetHours * 60 * 60 ) + ( currentTime.getTimezoneOffset() * 60 );

How to create a WordPress compatible slug in MySQL

Sometimes it is convenient to import terms or posts into a WordPress database. When you do, you may need to create a ‘slug’ column. To do this, I’ve modified a user defined function I found on StackOverflow or some similar site (possibly here: http://stackoverflow.com/questions/5409831/mysql-stored-function-to-create-a-slug/5410316 ). That version had some bugs. So I fixed them.

Here is my final script to create the UDF slugify.

Usage: select slugify(name), name from externaldata;

CREATE DEFINER=`thecode`@`localhost` FUNCTION `slugify`(`dirty_string` VARCHAR(200)) RETURNS varchar(200) CHARSET latin1
DETERMINISTIC
BEGIN
DECLARE x, y , z Int;
Declare temp_string, allowed_chars, new_string VarChar(200);
Declare is_allowed Bool;
Declare c, check_char VarChar(1);

set allowed_chars = “abcdefghijklmnopqrstuvwxyz0123456789-“;
set temp_string = lower(dirty_string);

Select temp_string Regexp(‘&’) Into x;
If x = 1 Then
Set temp_string = replace(temp_string, ‘&’, ‘ and ‘);
End If;

Select temp_string Regexp(‘[^a-z0-9]+’) into x;
If x = 1 then
set z = 1;
While z <= Char_length(temp_string) Do
Set c = Substring(temp_string, z, 1);
Set is_allowed = False;
Set y = 1;
Inner_Check: While y <= Char_length(allowed_chars) Do
If (strCmp(ascii(Substring(allowed_chars,y,1)), Ascii(c)) = 0) Then
Set is_allowed = True;
Leave Inner_Check;
End If;
Set y = y + 1;
End While;
If is_allowed = False Then
Set temp_string = Replace(temp_string, c, ‘-‘);
End If;

set z = z + 1;
End While;
End If;

Select temp_string Regexp(“^-|-$|'”) into x;
If x = 1 Then
Set temp_string = Replace(temp_string, “‘”, ”);
Set z = Char_length(temp_string);
Set y = Char_length(temp_string);
Dash_check: While z > 1 Do
If Strcmp(SubString(temp_string, -1, 1), ‘-‘) = 0 Then
Set temp_string = Substring(temp_string,1, y-1);
Set y = y – 1;
Else
Leave Dash_check;
End If;
Set z = z – 1;
End While;
End If;

Repeat
Select temp_string Regexp(“–“) into x;
If x = 1 Then
Set temp_string = Replace(temp_string, “–“, “-“);
End If;
Until x <> 1 End Repeat;

Return temp_string;
END

Help Me with Discussing Banner Sizes for Responsive Sites

I posted sent this to a client asking about what the right banner image size is for a #WordPress site. Where am I off and could have improved it?

[..]
So when creating custom headers for sites that are responsive and will be seen on different sizes, there are really three basic approaches:

1. Resizing/Scaling – The whole image is always shown, but it resizes smaller on smaller screens. The end result of this is that the detail of the the image is lots and titles that are now 1/4 the original size and are unreadable.

2. Centered – Allows for a single image to be used that can be as wide enough for a large screen, but only the middle is shown. This means that the most important info, like the title, has to be in the middle 320 pixels. It will also result in Google yelling at you because you are serving a very wide image on phones with a very limited width screen. A variance of this is left justified with the same results.

3. Multiple images – Based upon the size of the screen, the best image is displayed to the reader. This can be combined with #2 to cover multiple dimensions with less of a penalty from really wide images.

As with everything else, the answer that involves the most work, is the best answer. So #3 is best way to go.

With your last image, I created a three images (attached) that had the spirit of the first image. The first was just resized to fit the 1280 width screen.

The common sizes are: (http://bit.ly/1IAL98z)
320 for iphone 3&4,
768 for ipads,
1080 new tablets,
1280 for desktops & newer

You could go NUTS creating images for all the different dimensions. Take a look at the second article in the links below and you can see how many “common” breakpoints there are. If you create a site with three banners 320, 768, 1280, I think that covers most of the basis, especially if the readable content is mostly centered and can fall off the edges without any loss of message.

Some good articles:

How do you split a text field/textarea by line breaks?

Sometimes you want to provide a simple way for users to enter multiple values. Perhaps the simplest way for the user is to understand is allow them to enter new values on each line. Historically that’s how Internet Explorer allowed you to configure multiple home pages: 1 per line. It’s a tested method that works.

However, how do you then process the information? There are lots of possiblitities, however I prefer an answer I found was posted back in 2011: Use preg_split().

preg_split( '/\r\n|[\r\n]/', $_POST[ 'yourtextarea' ], PREG_SPLIT_NO_EMPTY )

By using regex, this function will handle entries from various platforms. You don’t need to worry about whether is just a carriage return or just a linefeed or even both at the end of a line. The split is handled nicely and you get an array returned. It will even, by adding an optional third parameter, ignore any blank lines. Once you have your value returned, you can write the array out to an option record, or process it however you like.

Once you have the array loaded from your DB, how do you split it into multiple lines again? That’s simple: Use implode().

implode( "\n",  $myarray );

Hope that helps someone!

WordPress and NotePad++

I use NetDrive and NotePad++ to do my WordPress Development, but I’ve customized NPP slightly along the way.
I’ve added the following functions:
Alt-F3 – Search the WordPress codex for the word at the cursor in the editor (usually for filters and actions etc)
Alt-F5 – Look up the word at the cursor as a function on the WordPress Developer wiki (will show the source)
Alt-F6 – Look up the word at the cursor as a function in the WordPress codex (will include examples)

To do this I edited shortcuts.xml

You can edit this file by closing notepad++ and then hitting WindowsKey+R and pasting in: notepad %AppData%\Notepad++\shortcuts.xml
And pressing enter.

How to find Joomla WordPress or Drupal version from Linux CLI

I was about to rewrite some of these queries again, and decided to google instead. I found this page with them already written: http://kb.iweb.com/entries/29801848-Verifying-CMS-versions-on-multiple-websites

So this too gets stored away in my cave. Enjoy:

WordPress version:

Linux/cPanel:

find /home/*/public_html/ -type f -iwholename “*/wp-includes/version.php” -exec grep -H “\$wp_version =” {} \;

Linux/Plesk:

find /var/www/vhosts/*/httpdocs/ -type f -iwholename “*/wp-includes/version.php” -exec grep -H “\$wp_version =” {} \;

Windows/IIS (default path) with Powershell:

Get-ChildItem -Path “C:\inetpub\wwwroot\” -Filter “version.php” -Recurse | Select-String -pattern “\`$wp_version =”

Joomla! 1/2/3 version and release:

Linux/cPanel:

find /home/*/public_html/ -type f $ -iwholename ‘*/libraries/joomla/version.php’ -o -iwholename ‘*/libraries/cms/version.php’ -o -iwholename ‘*/libraries/cms/version/version.php’ $ -print -exec perl -e ‘while (<>) { $release = $1 if m/ \$RELEASE\s+= .([\d.]+).;/; $dev = $1 if m/ \$DEV_LEVEL\s+= .(\d+).;/; } print qq($release.$dev\n);’ {} \; && echo “-“

Linux/Plesk:

find /var/www/vhosts/*/httpdocs/ -type f $ -iwholename ‘*/libraries/joomla/version.php’ -o -iwholename ‘*/libraries/cms/version.php’ -o -iwholename ‘*/libraries/cms/version/version.php’ $ -print -exec perl -e ‘while (<>) { $release = $1 if m/ \$RELEASE\s+= .([\d.]+).;/; $dev = $1 if m/ \$DEV_LEVEL\s+= .(\d+).;/; } print qq($release.$dev\n);’ {} \; && echo “-“

Drupal version:

Linux/cPanel:

find /home/*/public_html/ -type f -iwholename “*/modules/system/system.info” -exec grep -H “version = \”” {} \;

Linux/Plesk:

find /var/www/vhosts/*/httpdocs/ -type f -iwholename “*/modules/system/system.info” -exec grep -H “version = \”” {} \;

Latest version information:

What does “Is this ok [y/d/N]:” mean?

When installing new software using yum, you will occasionally get the the option of “Is this ok [y/d/N]:” Everyone knows recognizes Yes and No, but the option d may have thrown you for a loop.

“d” simply stands for download only. If you were to do this from the commandline you’d use this:

yum –download-only

Occasionally this is useful if you are prepping a resource, like a thumb drive, with all of the RPMs that you standardly install. You might also want to have the RPMs available for switching between versions of software. I’m sure there are many more reasons too.

Hopefully this has answered your question.

Advanced Google Search Operators

Sometimes a simple Google search won’t do. Today I needed to find some malformed URLs in a site. I couldn’t remember how to search for specific text in a URL.

I had a hard time finding the Google documentation of search commands this morning. It I needed the allinurl: function.

I don’t want to have to search that hard again so here is the documentation in my Code Cave:

Search Service	Search Operators
Web Search	`allinanchor:`, `allintext:`, `allintitle:`, `allinurl:`, `cache:`, `define:`, `filetype:`, `id:`, `inanchor:`, `info:`, `intext:`, `intitle:`, `inurl:`, `link:`, `related:`, `site:`
Image Search	`allintitle:`, `allinurl:`, `filetype:`, `inurl:`, `intitle:`, `site:`
Groups	`allintext:`, `allintitle:`, `author:`, `group:`, `insubject:`, `intext:`, `intitle:`
Directory	`allintext:`, `allintitle:`, `allinurl:`, `ext:`, `filetype:`, `intext:`, `intitle:`, `inurl:`
News	`allintext:`, `allintitle:`, `allinurl:`, `intext:`, `intitle:`, `inurl:`, `location:`, `source:`
Product Search	`allintext:`, `allintitle:`
