Re: [fw-mvc] Couple of Zend_Form questions

Hi

i have used your way, and it works. i get back json with this structure:

{
username: {
isEmpty: 'blah blah',
stringLengthTooShort: 'blah blah'
},
password: {
isEmpty: 'blah blah',
stringLengthTooShort: 'blah blah'
}
}

but i cannot append them to their corresponding input field. (i guess its
because i suck with javascript and jquery). how can i take the results for
the username field and append it to it, and the same for the password field?

best regards
