Im searching to build up or get the best solution for any wordpress-wordpress plugin that will permit a person to consider html clips ie, widget embed clips like youtube and soundcloud, or other html, paste inside a textarea within the wordpress after sales and save it to show inside a designated part of the site (in which the html is displayed won't be editable through the after sales or wordpress plugin but hard coded)

essentially getting challenge with saving the web coding via php.

thanks ahead of time for just about any help
