Preview Textarea

Generates a live preview lightbox of the formatted version of a textarea while editing an entry.

I've tested this extension with Symphony's default textarea field as well as Rowan's text box field. If you encounter issues with other textarea fields, please let me know.

Installation & Use

You can always install the latest version through git: git clone git://

  • Make sure that the extension is in a folder named preview_textarea. Upload this to your Symphony extensions folder.
  • Enable the extension from the Extensions page in the Symphony backend.
  • On the publishing page for a section, textareas will now have a Preview link next to their labels. This link will generate a formatted version of the textarea's content and display it as a preview lightbox.

If you want to change the styling on the preview, edit assets/preview_textarea.user.css and add your own styles.
