javascript - jQuery not serialize correctly -

i want ajax submit 2 form (for user , client). 2 forms identical user serialized expected, other 1 isn't. 2 forms return js function onsubmit="return edituser();" , onsubmit="return editclient();" respectively. try alert out serialize data , show user:

id=7&username=somethingelse&password=123&is_admin=0&client=1 

and client:

id=2&name=&logo=&phone=&email=&active=1&street=&city=&state=43&zip_code=  

with fields filled (the 3 values prefilled php code).

here js code ajax:

function edituser() {   console.log($('#edituserform').serialize());   $.ajax({     type: 'post',     url: 'edituser.php',     data: $('#edituserform').serialize(),     cache: false,     datatype:'json',     contenttype: "application/x-www-form-urlencoded; charset=utf-8",   }).always(function(){     renderusers();     $('body').removeclass('modal-open');     $('.modal-backdrop').remove();   });   return false; }  function editclient() {   console.log($('#editclientform').serialize());   $.ajax({     type: 'post',     url: 'editclient.php',     data: $('#editclientform').serialize(),     cache: false,     datatype:'json',     contenttype: "application/x-www-form-urlencoded; charset=utf-8"   }).always(function(){     renderusers();     $('body').removeclass('modal-open');     $('.modal-backdrop').remove();   });;   return false; } 

comment question, know i'm bad explaining stuffs. helping.

so sum question: why user , client function identical (different in id , fields in form) user works , client doesn't?

for more info please use this see result. login info : admin pass. after logged in, click on users tab in left sidebar , try update client, see not working still can edit user
