密碼字段更新爲空時，設置保存php和ajax

所以我有設置頁面，用戶可以更新他的信息。除密碼外，所有字段均可正常工作。當用戶點擊提交時，它將密碼更新爲mysql中的任何內容。我需要的是，如果密碼字段爲空，則密碼列中不會發生任何事情。密碼字段更新爲空時，設置保存php和ajax

的settings.php

$("#save").click(function(){ 
    var id=$("#hidid").val(); 
    var fname=$("#fname").val(); 
    var flastname=$("#flastname").val(); 
    var fusername=$("#fusername").val(); 
    var femail=$("#femail").val(); 
    var floc=$("#floc").val(); 
    var fdescr=$("#fdescr").val(); 
    var fslogan=$("#ffslogan").val(); 
    var day=$("#day").val(); 
    var month=$("#month").val(); 
    var year=$("#year").val(); 

    var noldpass=$("#noldpass").val(); 
    var roldpass=$("#roldpass").val(); 

    $.ajax({ 
     url:"s/fsave.php", 
     type:"POST", 
     data:"id=" + id + "&fname=" + fname + "&flastname=" + flastname + "&fusername=" + fusername + 
     "&femail=" + femail + "&floc=" + floc + "&fdescr=" + fdescr + "&fslogan=" + fslogan + 
     "&day=" + day + "&month=" + month + "&year=" + year + "&noldpass=" + noldpass + "&roldpass=" + roldpass, 
     success:function(data){ 
      alert(data); 
      $("#sc").show(); 
     } 
    }); 
});

嘗試改變條件

elseif ($noldpass == $roldpass)

到

elseif ($noldpass == $roldpass && trim($roldpass) != '')
