I'm beginning with Drupal. I've got to set up a multistep form which allows users to add content. I want them to be able to edit their own submissions too.
I began to code a custom module in drupal/php but I'm not sure it's the easiest way. I've heard a lot about Drupal native forms or content types that could do it as well as a custom module.
My question is : what kind of modules do I need to build a multistep form with own submissions edition ?
