Vanilla PDF Embed

Basic use

To embed a PDF you’ve uploaded to your WordPress site’s media
library, simply put the URL for the attachment page in your
post on its own line. The PDF will be embedded with the
default settings at that location, as if it were using oEmbed.

Examples:

Post short URL:

http://localhost/?p=9

Attachment default URL:

http://localhost/?attachment_id=9

Attachment pretty URL:

http://localhost/test/report1/

Media direct URL:

Click to access report1.pdf

This doesn’t work for PDFs hosted on other websites, or if you
need to change the parameters.

Using the [pdf] shorttag

If the PDF isn’t in your WordPress site’s media library, or if
you want to customize any parameters for the embed, then use
the [pdf]...[/pdf] shorttag. Between the tags, you’ll provide
the URL for the PDF to embed. If the PDF is in your WordPress
site’s media library, you can either give the attachment page
URL, or the URL to the PDF file directly.

The [pdf] shorttag accepts several optional parameters:

• width – sets the width of the frame the PDF is embedded in.
  By default, this is set to 100%.
• height – sets the height of the frame the PDF is embedded
  in. By default, this is unset.
• title – sets the title of the PDF, for use in the fallback
  link text.
• open_params – sets the PDF open params
  which control how the PDF file is displayed in the embed frame.
  These are poorly supported in browsers.

Examples:

Post short URL: [pdf width="200px"]http://localhost/?p=9[/pdf]
Attachment default URL: [pdf height="500em"]http://localhost/?attachment_id=9[/pdf]
Attachment pretty URL: [pdf title="Report 1"]http://localhost/test/report1/[/pdf]
Media direct URL: [pdf]http://localhost/wp-content/uploads/2013/11/report1.pdf[/pdf]
Change PDF open params: [pdf open_params="page=10&view=Fit"]http://localhost/?p=9[/pdf]

Compatibility

The PDF should be embedded in the page, with the document scaled so it fills the
embed frame horizontally. Unfortunately, embedding PDFs is not well-supported.

Auto-loading embedded PDFs

Unlike with images, web browsers may not automatically download and display
embedded PDFs when the page is loaded. For security reasons, some users prefer
not to allow the PDF plugin to run unless they trust the website the PDF comes
from. This generally leaves a grey rectangle that the user may click on to allow
the PDF to be downloaded and displayed.
