Purpose

The code snippet you provided is a PHP script that displays a PDF page from a specific resource, along with navigation controls for paging through the pages.

Functionality

• The script receives three POST parameters:

  • FOLDER: The folder name of the resource.
  • PREFIX: The prefix of the PDF file name.
  • PAGE: The page number to display.

• The script determines the resource title and navigation parameters based on the FOLDER value.

• It displays a table of navigation controls, including links to previous and next pages, as well as a dropdown menu to jump to a specific page.

• The script embeds an iframe to display the PDF page.

Features

• Navigation controls The navigation controls allow users to navigate through the PDF pages easily.
• Page jump The dropdown menu allows users to quickly jump to a specific page.
• PDF viewer The iframe provides a built-in PDF viewer for displaying the PDF page.

Usage

To use the script, you would need to:

1. Copy the code into a PHP file.
2. Specify the FOLDER, PREFIX, and PAGE values in the POST request.
3. Run the script.

Example

<form action="pdf_viewer.php" method="post">
    <input type="hidden" name="FOLDER" value="Penrice">
    <input type="hidden" name="PREFIX" value="penrice">
    <input type="hidden" name="PAGE" value="10">
    <input type="submit" value="View PDF Page">
</form>

Note

• The script assumes that the PDF files are located in the FOLDER directory.
• The PREFIX value is the prefix of the PDF file name.
• The PAGE value is the page number to display.
