I have a plain text field that encourages content editors to write a more detailed description of a piece of content.

However, on the front-end the template will use the post title by default if this is not supplied.

I would like the placeholder text for this optional plain text field to represent the reality of this in the Dashboard - i.e. to display the title field as the placeholder if the field has not otherwise been used.

When editing the field, I have tried setting the 'Placeholder Text' as {title}, but this does not work - it displays "{title}"!

Is this possible? I don't want to create a new custom type of field as it seems a little heavy handed for this use case.

Yeah, those placeholder text fields aren't dynamically parsed as Twig templates like others (Entry URL Format, etc.).

I don't want to create a new custom type of field as it seems a little heavy handed for this use case.

Unfortunately that's all that is coming to mind for me for this use-case.

  • Thanks Brad. Is it possible to create such a field that still stores the data exactly as it would if it was a regular text field? i.e. so if I switched it from my custom field back into a 'regular' text field, I wouldn't loose all my values in the DB? – ianp Mar 7 '17 at 13:34

    Assuming the custom field uses the same type and size datatype in the database, the conversion should happen automatically. – Brad Bell Mar 7 '17 at 19:50
