Symfony form widget custom rendering

Question

I am looking for a way to automate a form output to json format instead of html. I am using JQuery dform http://plugins.jquery.com/project/dform to create dynamic forms.

Sample output:

{ "type" : "p", "html" : "You must login" }, { "name" : "username", "id" : "txt-username", "caption" : "Username", "type" : "text", "placeholder" : "E.g. [email protected]" }, { "name" : "password", "caption" : "Password", "type" : "password" }, { "type" : "submit", "value" : "Login" }

Please help

Create a renderJSON method and attach it to BaseForm. The method would iterate through the the sfFormFields and build an array that you could then pass to json_encode.

An ideal solution would be to inject your own class into the sfWidgetForm inheritance chain with a renderJSON method so that individual widgets can control their JSON format. Unfortunately, Symfony makes this very difficult to do.

Sorry what do you mean by attach it to BaseForm, you mean rewrite the symfony file?

No, the Symfony sfForm inheritance chain contains a BaseForm class that is yours to add methods to.

He means BaseForm in lib/form/BaseForm.class.php.

but every widget has its own render, how do you add JsonRender without touching the Widget classes?
