Our custom installation has a feature that allows files to be replaced at a later date, without editing the pages that refer to them, or even updating the links associated with them.
The philosophy behind this method is that you may have a link to a file that is always available on your website, but the file itself changes periodically. For instance, a dress code, newsletter, calendar, etc.
Best practice would be to initially setup the file with a “common name” so that it is not tied to a date or other time identification. In other words, you will want to upload a document called “newsletter.pdf” instead of “October-2012.pdf”. This serves several purposes. For one, if someone wants to add a link to the newsletter in their Favorites/Bookmarks, they can do so, and always have the updated version of the file. The second reason is that maintenance for you will be easier, since you will only have to replace the file itself and not the underlying links, which could be present in multiple areas of the website.
To accomplish this:
Upload a document to “Media” and create a link to it from your sidebar or web page (the method for uploading and linking is in the previous tutorial).
To replace the file, go into “Media” and search for the file you wish to replace. Click edit to open the file for editing. With the file open for editing, click the “Upload a new file” button.
You will then be presented with two options:
Most times, you’ll just browse for the file, and leave the default on “Just replace the file” and click “Upload”.
However if you had named the file poorly before, and wish to update to a more generic name, you can do so by browsing for the file, then select “Replace the file, use new file name and update all links” and click “Upload”. This will replace the existing links with the new file name and relink all the references to your old file automatically!!
