More information about default values of form fields

[modir]

It would be great if the page https://docs.contao.org/manual/de/formulargenerator/formularfelder/ would have more information about default values of form fields, Especially about dynamic default values. E.g. How can I set the current date as the default value. Or how can I set a GET parameter as a default value.

E.g. How can I set the current date as the default value. Or how can I set a GET parameter as a default value.

The recommended way in my opinion would be to use a loadFormField hook and then pre-fill the widget's value with whatever you need, while keeping security in mind.

I recently added this functionality to https://github.com/inspiredminds/contao-extended-form-fields though. With that extension installed you can enable a setting for each form field where its default value would be extracted from a query parameter of the same name.

Thank you Fritz. In the forums many write about another solution. That I would have to write something like {{GET:variableName}} into the default field. Hence I thought it would be great to have a better documentation about it. To have a solution is one thing. To have a better documentation another. And this issue here is now because of the documentation and not about finding a solution. But thanks again.

I know ;). The ticket is not closed.

Probably something like {{file::get.php?…}}, but that's not very elegant and thus I would be reluctant to add that to the documentation as an official solution.
