Hi Dorthe!

+1 for details on different event times (when to use what)
+1 for making sure we're showing at least one outside "thing" being made accessible to the event listener, whether this is some outside data or a service
-1 for the re-ordering - I believe this is the responsibility right now (for better or worse) of the template

We should review the document and make these changes, but only after #1842 has been merged in.

Thanks!

Ryan, that's perfectly fine that ordering is done in the template, but it should be noted somewhere. My English is sometimes ... interesting... but if I can support you somehow in preparing something, let me know :-)

This issue is ready to be worked on - there are additional changes needed in #2464.

I do believe the YAML configuration sample at the end of this page has some typos.

@cheesemacfly what do you mean?

@xabbuh Shouldn't the @doctrine argument for acme.form.meetup_registration_listener be @doctrine.orm.entity_manager instead?

@cheesemacfly you're completely correct. There is already a fix for that in #2743

@wouterj you are right. Thanks for the information!

I've just merged in that fix! I'm going to close this issue - my intention was to use #2464 going forward to follow the issues with this entry.

Thanks!

Hi guys,

would you be kind, and share the link where I can find these additional documentation?
I'm getting issues build up that example based on just those information from the cookbook (http://symfony.com/doc/current/cookbook/form/dynamic_form_modification.html).

Thank you in advance.

Hi @barnibx, which additional documentation are you talking about?

Hi @xabbuh,
I was referring to @weaverryan 's comment, on:
+1 for details on different event times (when to use what)
+1 for making sure we're showing at least one outside "thing" being made accessible to the event listener, whether this is some outside data or a service
-1 for the re-ordering - I believe this is the responsibility right now (for better or worse) of the template.

I realized after my comments, that I can check the modifications on each issue (#xxc), but I was wondering if these additions can be found in one place with some examples.

Thanks for your question.

Hey @barnibx - these have all been put into different parts in this article: http://symfony.com/doc/current/cookbook/form/dynamic_form_modification.html. We more or less addressed these issues, but we don't talk directly about, for example, when to use the different form events (that article uses FormEvents::PRE_SET_DATA several times). If there's something missing that you'd like to see, please definitely open an issue :).

Cheers!

HI @weaverryan,

Thanks for your response.
Maybe I missed something, but I think it would be really useful if you could add an example/explanation how can be built a dynamic form with changing more fields depending on another field.
For example if I have a list of checkboxes for a country regions, and each region has his own fields which needs to be completed. So what would be a nice solution(based on form events) to show different twig templates on each region selection.
I understand that this will affect different sections (entities, controllers, twig templates, AJAX calls) but I think this tutorial it would make some developer's life much easier :)

Thanks in advance.
