E&T Filter: Import Missing Tags in the Excerpt

Sometimes, during import, when using the Excerpts word limit setting, some tags might be removed.

In these cases, please use the below filter if you’d like to be able to keep the missing tags in the excerpts. This example uses the <img> tag as an example:

add_filter('wprss_et_allowed_tags_in_excerpts', function($tags) {
    $tags = array_merge($tags, array('img'));
    $tags = array_flip($tags);
    $tags = array_keys($tags);

    return $tags;
});

The creation of the excerpts works by removing all tags, trimming what’s left, and then adding the tags back. This ensures that content doesn’t get trimmed in the middle of a tag, thus breaking the HTML, and that only actual text gets counted towards the “words” that get trimmed. When adding the tags back into the content, however, only some are processed.

By default, the tags that get added back are the following:  <a> <span> <i> <b> <strong> <u>.

This is deliberate and is done to improve security. This list may be changed via the  wprss_et_allowed_tags_in_excerpts filter for  Excerpts & Thumbnails as shown above.
