Example: Embedding the "Showcase" Post-Template

• one anonymous parameter which is being set to "@showcase" which is shorthand for "globals/showcase".The global variables are specified in the settings page of the plugin. On that page "showcase" contains the number of the post-template to embed - "55".
• The class of the devices to show. We are overriding "class" which is defined as a custom variable for post 55.
• The brand of the devices to show. We are overriding "brand" which is defined as a custom variable for post 55.

What's Inside the "Showcase" Post-Template?

The "DealPost" Post-Template (Individual Deal Boxes)

The best way to work with template designs in Wordpress' would be a combination of visual and html modes. You can also use an external html editor to design your deal box and then copy the html into your post in html mode.

• "image" - A link to the image to display.
• "lines" - The lines to display in the deal box.
• "link" - A link to the deal.
• "title" - The title of the deal.
• "monthly" - The monthly amount to pay.
• "months" - The number of months to pay.
• "specs" - The device's specifications.

How do I install the Wordpress Post-Template plugin?

1. Unzip the zip file into your Wordpress ".../wp-content/plugins" folder.
2. "Activate" the plugin on the dashboard "Plugins" page.

This is an example of using the WP XML Template plug in to produce indented and syntax highlighted XML that can be embedded in your posts or pages. The template can be defined using the following recursive markup:

{rewrite}<span style="display: block; color: purple; background: [background];">&lt;[name(xml)]<span style="color: red;">{rewrite:attr xml/@*} [name(attr)]="<span style="color: blue;">[htmlencode(xmlencode(attr))]</span>"{/rewrite:attr}</span>&gt;<span style="color: black;">[htmlencode(xmlencode(xml))]</span>{rewrite:tag xml/*}<span style="display: block; margin-left: 20px;">[call(@id,xml[tag],background[background])]</span>{/rewrite:tag}&lt;/[name(xml)]&gt;</span>{/rewrite}

which in visual mode will look like this:

{rewrite}<[name(xml)]{rewrite:attr xml/@*} [name(attr)]="[htmlencode(xmlencode(attr))]"{/rewrite:attr}>[htmlencode(xmlencode(xml))]{rewrite:tag xml/*}[call(@id,xml[tag],background[background])]{/rewrite:tag}</[name(xml)]>{/rewrite}

and this is how you embed it:

{rewrite}[call(@prettyxml, background{lightgray}, xml[loadxml({../uploads/file.xml})])]{/rewrite}

and this is what it produces:

<devices><device class="Mobile Phone" brand="Apple" model="iPhone 4 16GB Refreshed"><specs>5.0 megapixel camera with LED flash. HD video recording &amp; editing.

In this case "prettyxml" is defined as a global variable on the plugin's settings page and it contains the post number of the template. "background" is defined as a custom variable on the template post itself.
