Remember the code?

OK , I was working this my random sidebar image rotator. It uses ajax component to get html codes to show random images and it automatically rotates the image in every defined seconds.

In order to show horizontal and vertical images in a same spaced area, I have assigned pre defined squre div element and make the ajax component to get html codes and set innetHTML property of this <div> element. The <img> element should be aligned in the center using calculated top and left CSS property.

So this is what I wanted to display (Normal) viewd with Firefox.

But when I tried with IE 7, I got below. It seems as if the <style> tag didn’t exist. The image was not aligned properly in the center.

This is wordpress’s own plugin repository http://wordpress.org/extend/plugins/ .

Once create your id, you can upload your plugin and share with the world. By the way, the plugin must be GPL compliant.

Anyway, I had a hard time uploading my plugin Hana Flv Player because the necessary instructions are there but not in details missing something here and missing something there.

So here is my explanation. I hope that this will help someone too.

First little bit about readme.txt file. You need to create a readme.txt file.
Make sure you define the Stable tag to indicate the current version.

In order to use <code></code>, use backtick (`). Therefore `THIS IS CODE` will become <code>THIS IS CODE</code>

If you want to add screeshots, you need to define below section in your readme.txt and place the corresponding image in base trunk folder (refer svn section below for trunk folder . This is basically your plugin local folder to work with svn) The image file name should be in format of screenshot-num.jpg. where num is actual sequentially increasing number. (screenshot-1.jpg, screenshot-2.jpg, screenshot-3.jpg…) Each descriptions go into the readme file with the corresponding number. So the screenshot-1.jpg will be shown with the description “Plugin Settings Page” as it was used with number 1.

== Screenshots ==
 
1. Plugin Settings Page.
2. Adding the hana-flv-player tag in an article.
3. Example video working.

Perl is a powerful script language which is much faster than simple shell script and there are lots of libraries that support virtually every tasks out there. But it is little difficult to learn at first.

One of the weak area of perl is that it doesn’t support multi dimensional array naturally. In order to implement multi dimensional array, you will need to use pointer references. (There may be other ways)

You can referece variable and array by adding "\" backslash in front of the variable.

For example

#create array
@a = (1,2,3,4,5,6);
 
#create reference to array a
$aref=\@a;

In order to access the variable,you just add the proper symbol in front of the var name.
You will need to use the referenced variable name with the ‘$’ sign intact.

• if you are accessing it as a array , @$ref would refer to the whole array
• if you are accessing the element of the array , $$ref[0] would refer the first element.

#To access the first element of the referenced array
print "first element: " . $$arref[1] . "\n";  # this will print '2'
