# Feature: #106072 - Introduce regex-based replacements for slugs {#feature-106072-1738662608}

See [forge#106072](https://forge.typo3.org/issues/106072)

## Description {#description}

A second replacement configuration array has been added to support
regular expression (regex)-based definitions. This allows defining
case-insensitive or wildcard replacements for slug generation.

> [!NOTE]
> Regular expression replacements are applied **before** any sanitation
> of the field values takes place. This means:
>
> -   Values are still in their original form - not lowercased or otherwise processed.
> -   The replacements apply only to the fields defined in
>     `['generatorOptions']['fields']`.
> -   No automatic escaping or character detection is performed, so
>     patterns must be written carefully.
>
> Keep these points in mind when defining regex patterns.

## Impact {#impact}

Slug fields now support a new `regexReplacements` configuration array
inside `generatorOptions`.

**Example TCA configuration**

```php
$GLOBALS['TCA'][$table]['columns']['slug']['config']['generatorOptions']['regexReplacements'] => [
    // Case-insensitive replacement of Foo, foo, FOO, etc. with "bar"
    '/foo/i' => 'bar',
    // Remove string wrapped in parentheses
    '/\(.*\)/' => '',
    // Same, using a custom regex delimiter
    '@\(.*\)@' => '',
];
```
