Call content() method in Model (Kirby 4)

Kirby 4 Solved ✔️

Hi,

I just updated a kirby 3 project to Kirby 4 and I get an error in a Model page where I overwrite the Page content method.

In Kirby 3, I used this syntax:

public function content( $languageCode ) { ... }

Now in Kirby 4, this line return an Exception

Content must be compatible with Kirby\Cms\ModelWithContent::content(?string $languageCode = null): Kirby\Content\Content

So I suppose there is another syntax in Kirby 4 to call the content() method in our Model ?

I tried this without success:

public function content( $languageCode ): Content { ... }

That’s the new method signature, so you would have to add the type hint for the language code, set the default and add the return type.

public function content(string|null $languageCode = null): Content

Thanks Sonja, I made the correction but get this Exception now:

“Could not check compatibility between ProposalPage::content(?string $languageCode = null): Content and Kirby\Cms\ModelWithContent::content(?string $languageCode = null): Kirby\Content\Content, because class Content is not available”

You need to either import the class or use the FQN Kirby\Content\Content

Yep, works now! Thank you very much :slight_smile:
