Embedding external content

Embedding external content

Extension module for embedding external content

This is how the privacy-compliant integration of content from social networks on the websites of the TU Chemnitz works.
When you click on the button, a pop-up first opens to confirm data transmission to the external service, and only then is the actual content displayed.

Function and features of the module

  • data protection-compliant integration of plugins from social networks and map services (2-click solution, first confirmation for data transmission via pop-up)
  • the following services are currently supported: Facebook (post, comment, video), Google Maps (map), Instagram (photo), OpenStreetMap (map, API), X former Twitter (post, timeline), YouTube (video)

Integration of the module

In the TUCAL editor, this information is entered in the „Seiteneinstellungen (PHP)“ (page settings) text field:

require_once('php/ext.inc');
page settings in the editor

Basic structure

echo ext_embed(string $code [, array($options)])

Possible parameters

  • $code | PHP string
    • source code to be embedded from the service for embedding/embedding the plugins (e. g. YouTube link)
  • $options | PHP array [optional]
    • Array of values that affect the style
    • Possible entries:
      'button' (changes the text or replaces the button with HTML objects e. g. images),
      'css_class' (sets a self-defined CSS class around the plugin)

There is one more functionality (ext_hs_url()) which calls a pop-up with the external content. Details and examples can be found in the documentation.

Examples

echo ext_embed('<iframe src="https://www.youtube.com/embed/I2l1CtdiVzI" [...] ></iframe>');
