# Important: Page title placeholders take only text and numbers {#important-ace-915-academic-persons}

## Description {#description}

A placeholder of the page title format of the profile detail view, the field
**PageTitle display format**, is replaced with the result of the
profile getter it names: `%%FIRST_NAME%%` with `getFirstName()`. A
getter that returns no string ended every detail page using the format with a
PHP type error, for example `%%UID%%`, which returns an integer,
`%%IMAGE%%`, which returns `null` for a profile without an image and a
file reference otherwise, or `%%CONTRACTS%%`, which returns a list of
records. The listeners of
`\FGTCLB\AcademicPersons\Event\ModifyProfileTitlePlaceholderReplacementEvent`
were never reached.

The page title now takes the result of a getter when it is a string, as
before, or a number, which is written as it is: `%%UID%%` gives the uid of
the profile, on a translated page the uid of the profile in the default
language. Every other result, `null`, a boolean, an object or an
array, leaves the placeholder in the title as it is written, the same as a
placeholder that names no getter. A boolean is not written as `1` or as an
empty text, neither reads as a title. A getter that is not public or that
requires an argument is not called and leaves the placeholder as well.

## Impact {#impact}

A detail page whose format names such a getter now renders. The placeholder
stays in the page title, with its `%%`, unless a listener of
`ModifyProfileTitlePlaceholderReplacementEvent` replaces it. The listener
receives it unreplaced, `getReplacement()` returns the same text as
`getPlaceholder()`, and an empty replacement removes it from the title.

## Affected Installations {#affected-installations}

Installations whose page title format names a getter that returns no string.
Nothing has to be done on update. A site that wants a text for such a
placeholder, the number of contracts for example, sets it in a listener of the
event, see [Feature: Introduce PSR-14 ModifyProfileTitlePlaceholderReplacementEvent in ProfileTitleProvider](https://docs.typo3.org/permalink/fgtclb/academic-persons:feature-1746706500@main).
