function mee_filter_process in Scald: Media Management made easy 7

Process callback for the 'mee_scald_widgets' filter.

This expends the embed marker into the themed "atom embed" markup. The atom itself is not rendered yet, since that is not cacheable. Instead, a placeholder SAS code is left, that will be replaced in mee_field_attach_view_alter().

Parameters

string $text: The text to process.

Return value

string The processed text.
