Cookie Services

Iframe Manager

The iframe manager is responsible for blocking third-party content.

In the field, iframe_notice text is stored that the user sees when the content is blocked.

• iframe_load_btn Loads the Content of current Div
• iframe_load_all_btn Loads all Content from same Service on same site

Since version 1.7.0, the Iframe Manager includes a thumbnail feature that displays a placeholder image for blocked iframe content until the user consents to the service. By default, the thumbnail is autogenerated, but it can be customized by providing a valid URL or by using a JavaScript function in the Backend "Cookie-Service" configuration.

If no custom thumbnail is provided, the Iframe Manager will fallback to a default image, which is stored at /typo3temp/assets/cfthumbnails/*, they are generated automatically and cached for 7 days. Using the Thumbnail-API can be disabled in the Extension Settings.

Advanced Iframe Configuration

iframe_thumbnail_url set valid url for automatic thumbnails or use a Javascript function

iframe_embed_url is called on Successful Accept can also use a Javascript function

Example Iframe Thumbnail function

function(id, callback){
  let parts = id.split("/");
  let videoId = parts[parts.length - 1];
  let videoIdParts = videoId.split("?");
  let videoIds = videoIdParts[0];
  var url = "https://vimeo.com/api/v2/video/"+videoIds +".json";
  var xhttp = new XMLHttpRequest();
  xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      var src = JSON.parse(this.response)[0].thumbnail_large;
      callback(src);
    }
  };
  xhttp.open("GET", url, true);
  xhttp.send();
}

Advanced Iframe Styling (Boostrap Package or Text-Media)

If you want to adjust the iframe styling or have responsive issues in combination with the Bootstrap package or other CSS-Ratio hacks, such as the height of the iframe being rendered incorrectly, you can adjust the iframe styling.

We have some default parameters that we set, such as min-height or min-width, which you can easily override with this code at the service level.

.your-container-wrapper div[data-service="(service-identifier-from-db)"] { min-width: auto; }

.my-widget div[data-service="youtube"] { min-width: auto; }

If you are using the Text-Media element with a CSS padding hack such as padding-top: 56.25%, or (.embed-responsive-16by9:before..) you can adjust the iframe styling as follows.

Set the .embed-responsive to position: relative; and the iframe-pseudo-div to position: absolute;.

 .embed-responsive{
   position: relative;
 }

.embed-responsive [data-autoscale] {
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    width: 100%;
    height: 100%;
    border: 0;
}

Script Configuration

OptInCode opt_in_code is executed when the user accepts the service. By default, some services do not have an OptInCode as cookie management happens automatically based on the assigned cookies. This code is only needed to execute additional JavaScript when the user accepts the service.

OptOutCode opt_out_code is executed when the user block the service. By default, some services do not have an OptOutCode as cookie management happens automatically based on the assigned cookies. This code is only needed to execute additional JavaScript when the user block the service.

Fallback Code [fallback_code] is not in use, TODO.

External Script Configuration
