# Deprecation: #80510 - ContentObjectRenderer->URLqMark {#deprecation-80510}

See [forge#80510](https://forge.typo3.org/issues/80510)

## Description {#description}

The PHP method `ContentObjectRenderer->URLqMark()` has been marked as deprecated. It was
used to add a `?` between two strings if the first one does contain a `?` already.

Its main purpose is to add query string parameters to a given URL.

## Impact {#impact}

Calling the method above will trigger a deprecation warning.

## Affected Installations {#affected-installations}

Any installation using custom extensions calling this method.

## Migration {#migration}

Implement this functionality with PHP's native `(strpos($haystack, '?') !== false ? '?' : '')`
one-liner directly.
