One has a multitude of possibilities in this case:
One can get the form element (the button) from the form and try to -
>setAttrib('disabled', 'false'), which should try and set the
parameter to the button html object to false, therefore allow for the
button to be used. Check the source to see if this is working; in the
button tag, you should see a "disabled:false" directive. More details
about the attributes of the button html tag can be found online.
One can write a javascript in the view script that would, depending on
the get argument, set the disabled attribute to false. This may
require you to pass the request variable to javascript, however.
One can, instead, by default enable all buttons on the form, but in
the controller action, disable the buttons which will not be used
depending upon the request variable (a reversal of what you're doing,
but it may work depending on how you're doing it).
Hopefully this helps some.

Hi all,
I am developing a application which need buttons to be enabled on
request
type.
On my first page there are links to different pages like 'update',
'register', 'send mail' etc.
On click of any of these links a search page opens where user can
search for
people by name and a list of people is displayed. This search page has
button for update, register, send mail etc respective button will
take you
to respecive page.
Now all these buttons are disabled in form.xml and depending on
request
type (ie update, register etc ) I have to enable that respective
button
only.
I am enable to retrieve button with $form->getElement($name);
But I am not able to enable it.
Can anybody suggest proper method for enabling this button.
Thanks in advance,
Aniket
