How To Use
Rules about the links to be protected
The links that refer to files and will be protected by Download Link Protection must follow the following rules:
- The path to the file should be relative starting from the Joomla's installation folder. e.g. "images/pdf/brochure.pdf"
- The path to the file should NOT be a URL or an absolute path (starting from the root folder).
- The path to the file should be consisted by latin characters (a-z), numbers (0-9), middle dash (-), underscore (_). Spaces or special characters are not allowed and may cause problems.
Protect a link that is accesible throught the editor
In order to protect the URL of a link, the only thing you need to do is to enable the plugin and add the word 'downloadlinkprotection' as class of the link. While editing the text that contains the link, use your editor in order to add 'downloadlinkprotection' as class of the link (without the quotes).
Protect a link or many links massively that are specified by a CSS selector
If you want to protect more links that are not editable through the editor, then you can add more CSS selectors in the field "CSS Selectors" of the extension. Example: .downloadlinkprotection, .pdf a, #client .download-link
- In the Joomla control panel select: "Extensions" > "Plugins" > "System - Download Link Protection".
- In the field 'CSS Selectors' add the selector from your links. See below the example for more details.
- Save the plugin.
Example: Let's suppose that there is an area in your website containing links to be protected. If this area has the class 'safe-links', the links in this area will be selected by the selector '.safe-links a'. You have to add this selector in the field 'CSS Selectors' of the plugin. So it will be like this: '.downloadlinkprotection, .safe-links a'.
- CSS Selectors: The CSS selectors for the links to be protected. You can change the default class or add more selectors in order to select massively the links to be protected. Example: .downloadlinkprotection, .pdf a, #client .download-link
- Download Extensions: This field defines which file types will be downloaded and not opened through the browser. You can add more file types or remove some.
- Link Parameter Name: This field defines the URL parameter of the protected URL that holds the identification number for the real URL. Example: http://www.domain.com?[link_parameter_name]=1234567890
- No File: Message to appear when the file doesn't exist. HTML is allowed.
- Lock Icon: This parameter shows the lock symbol at the left of the text of the link in order to be easier for the user and admin to distinguish which link is protected. In order this to work, the template must load the Font Awesome toolkit.
