Custom Word Cloud

Creates custom word cloud images based on page content or POST variable named content.

The custom word cloud plugin will generate word cloud images based on page content or the contents of a form POST input named "content". The cloud is specified using shortcode tags on the page where the content or form exist.

Example 1

As an example the following entered into a WordPress page will result in a page with a word cloud image displayed above the paragraph that is a link map with google searches for each word in the cloud:

[cwcloud]  
[cwcimage]  
[cwcmap]

We the People  of the United States, in Order to form a more perfect Union,
establish Justice, insure domestic Tranquility, provide for the common
defence, promote the general Welfare, and secure the Blessings of Liberty to
ourselves and our Posterity, do ordain and establish this Constitution for the
United States of America.

[/cwcloud]

Example 2

Another example where a user may enter their own paragraph of text and generate a custom word cloud:

[cwcloud post="true" id="mycloud"]  
[cwcmap]  
[cwcimage]  
<form method="post">  
<textarea cols="40" rows="10" name="content">[cwcpostcontent]</textarea>  
[cwcform]  
<input type="submit" value="Build Cloud" />
</form>
[/cwcloud]

Example 3

An example of a form with attributes set to some custom default settings and the id attribute is not set so a fresh id will be generated for each user created word cloud:

[cwcloud post="true" palette="#046, #fe0, #2f2, #82f" width="500" height="250"
word_limit="30"]
[cwcimage]
[cwcdownloadlink]
<form method="post"><textarea cols="40" rows="10"
name="content">[cwcpostcontent]</textarea>
<input type="submit" value="Build Cloud" /> [cwcform]
</form>
[/cwcloud]
