Default How to: Custom Widget Type

I've been working on a site that is hosting a fairly large number of flash videos. I've been using static html widgets and pasting in the html to display the flash player/video for each. Each flash video consists of its own directory containing four files (a .swf, an .mp4, a .png and a .js).

It works, but there are two problems:
  1. The html has to be edited for each widget to set the correct path and file name which is time-consuming and error-prone
  2. If the format (e.g. the size, etc..) of the videos were to change, all the widgets would have to be edited.

To get around this, I created a custom widget type that has two configuration variables: a path and a swf filename. The widget code generates html from these two parameters and displays it. I would like to package this as a mod, but I don't know how to do that yet. Maybe someone could give me some pointers...?

This article: http://www.vbulletin.com/forum/entry...page3#comments is a bit out of date, but gave me a starting place.

Here are essentially the steps I used.

Database
PHP Code:
Insert Into product(titledescriptionversionactiveurlversioncheckurl)
values ('amutil''Agedman Utilities''Agedman Custom Widget Types''1.0'1'''');
Insert into package(productid, class)
values ('amutil''AmUtil');
Insert into cms_widgettype(class, packageid)
values ('AmFlash'last_insert_id()); 
AdminCp
Add a new phrase with
type: 'CMS Widget Types'
product: 'Agedman Utilities'
varname: 'widgettype_amutil_amflash'
text: 'Standard Flash Video'

Create two templates (modified versions of the ones used by the static html widget type):
1. Display template for displaying the widget in a section (this is actually an exact copy of the one for the static html widget type).
title: amutil_widget_amflash_page
template:

HTML Code:
<div class="cms_widget">
	<div class="block">
		<div class="cms_widget_header">
		<h3>{vb:raw widget_title}</h3>
		</div>
		<div class="cms_widget_content">
		{vb:raw static_html}
		</div>
	</div>
</div>
2. Configuration template for editing the widget (modified -- removed 'statichtml' field, added 'path' and 'filename' fields.
title: amutil_widget_amflash_config
template:
HTML Code:
<div id="overlay1" style="height:190px;width:400px">
	<div class="cms_widget_config">
		<div class="fullwidth">
			<label for="path" class="label">Path w/o Final Separator:</label>
			<textarea name="path" id="path" cols="50" rows="2">{vb:raw path}</textarea>
			<label for="filename" class="label">SWF Filename w/ suffix:</label>
			<textarea name="filename" id="filename" cols="50" rows="2">{vb:raw filename}</textarea>
		</div>
		<div class="fullwidth">
			<label for="template_name" class="label">{vb:rawphrase template_name}</label>
			<input class="button" name="template_name" id="template_name" size="40" value="{vb:raw template_name}" tabindex="1" />
		</div>
		<input type="hidden" name="do" value="config" />
		<input type="hidden" name="item_type" value="{vb:raw item_type}" />
		<input type="hidden" name="item_class" value="{vb:raw item_class}" />
		<input type="hidden" name="item_id" value="{vb:raw item_id}" />
		<input type="hidden" name="s" value="{vb:raw session.sessionhash}" />
		<input type="hidden" name="securitytoken" value="{vb:raw bbuserinfo.securitytoken}" />
	</div>
</div>
File System
Make directories: /packages/amutil/widget/ and /packages/amutil/item/widget/

Copy class definition file (use the static html widget code as a starting place)
cp /packages/vbcms/item/widget/static.php /packages/amutil/item/widget/amflash.php

Copy main class file (use the static html widget code as a starting place)
cp /packages/vbcms/widget/static.php /packages/amutil/widget/amflash.php

Edited Item Class File (most original comments removed)
PHP Code:
// Modified this line to add the package and class names
class AmUtil_Item_Widget_AmFlash extends vBCms_Item_Widget
{
    
// Modified this line with my class name
    
protected $class 'AmFlash';

        
// added 'path' and 'filename' fields.  Note: we need to keep the 'statichtml' field, here or nothing will display on the page...

Note: you may need to clear the CMS Cache before you will see the new Widget Type show up in the drop-down list -- I did.
