PHP Class – Calendar Matrix
by jandrews on Mar.08, 2010, under PHP Development
The other night I found myself needing a PHP class file that would give me calendar data. Specifically I needed something that I could build a calendar display with. The problem was I didn’t want it to write the HTML, I just wanted it to give me a multidimesional array of weeks and days. That way I could have whatever content I wanted in it. Not finding anything that didn’t write out HTML I created the CalendarMatrix class.

The class is designed to mostly work like an array. With one exception, you can not modify an indexed value. It does how ever allow you to use for, and foreach statements to iterate through the array.
// Instantiate the matrix using the year and month in the constructor.
$matrix = new CalendarMatrix(2010, 03);
The matrix will now initialize itself with the constructor and you can use it like so.
<table>
<?php foreach($matrix as $week): ?>
<tr>
<?php foreach($week as $day): ?>
<td<>?php echo $day; ?></td>
<?php endforeach; ?>
</tr>
<?php endforeach; ?>
</table>
The code will now have created an calendar with the first row being Monday the last row being Sunday. There is also a function go build the day header at the top.
<table>
<tr>
<?php foreach($matrix->calendarDayHeaderArray() as $dayName): ?>
<th><?php echo $dayName; ?></th>
<?php endforeach; ?>
</tr>
<?php foreach($matrix as $week): ?>
<tr>
<?php foreach($week as $day): ?>
<td<>?php echo $day; ?></td>
<?php endforeach; ?>
</tr>
<?php endforeach; ?>
</table>
It is also flexible enough to be used to build a calendar out of divs simpley use both foreach calls next to each other and then put a div in the middle instead of a <td> tag.

I am sure people have written something similar 1000 times, but with time they fade from the internet. Today I will share with you my Random String generating php class. Are you ready?

}
}
This class is useful anytime you need a random string of any length. All the functions are called staticly, so no need to create an object just call the class.
Example 1:
Create a random string of 12 lowercase-alphabet characters
print RandomString::generateRandomAlphaString(12);
Example 2:
Create a random string of 12 uppercase-alphabet characters
print RandomString::generateRandomAlphaString(12, 'upper');
Example 3:
Create a random string of 12 mixed-case-alphabet characters
print RandomString::generateRandomAlphaString(12, 'mixed');
Example 4:
Create a random string of 12 number characters
print RandomString::generateRandomNumericString(12);
Example 5:
Create a random string of 12 number characters or lower-case alphabet characters
print RandomString::generateRandomAlphaNumericString(12);
Example 6:
Create a random string of 12 number characters or upper-case alphabet characters
print RandomString::generateRandomAlphaNumericString(12, 'upper');
Example 7:
Create a random string of 12 number characters or mixed-case alphabet characters
print RandomString::generateRandomAlphaNumericString(12, 'mixed');
Example 8:
Create a random string of 12 number characters, mixed-case alphabet characters, or special characters
print RandomString::generateRandomStringWithAll(12);
This class will pretty much fill all your random string needs. Feel free to use it if you like, or make suggestions to changes, to make it better.
Full Circle v0.5.1 Release
by jandrews on Mar.31, 2009, under PHP Development
I am happy to announce the release of Full Circle v0.5.1 This is a new feature release. I asked for feature requests, and Gary mentioned he would like to be able to enable disable posting to facebook and only enable it on certain posts. It was a relatively easy feature to add, so I did.
At the bottom of the advanced edit page. You will find 2 new checkbox fields at the bottom of the page. One for twitter one for Facebook. You can disable one or both. In your Full Circle settings page, you can enable Facebook and twitter, but set their default to be disabled posting. If this is the case then the 2 new checkbox fields on the advanced edit page will be unchecked. Checking them pushes the post to which ever ones you have activated.
Full Circle V0.42
by jandrews on Mar.30, 2009, under PHP Development
OK new version of Full Circle. This one includes the ability to include links at the bottom of your blog posts. Just another step in making Full Circle the only plugin you need to advertise your blog posts on your social networks. I’d be interested in what other networks people think they need to have included. Friend of mine mentioned linked in, so I am going to go look at linkedin’s api and see what I come up with. Who knows that may be v0.5
The new version is available here. http://wordpress.org/extend/plugins/full-circle/
Full Circle v0.3
by jandrews on Mar.30, 2009, under PHP Development
New Version of Full Circle is now available at the WordPress plugin archive. Plugin now offers the ability to connect to your Facebook feed and your Twitter feed. All done in one handy dandy little plugin instead of 2.
