我想将laravel控制器中的数据更新到数据库， 我能够更新模型中的数据，但我无法将数据更新到数据库
这是我的视图或HTML编码
function editdata(data)
{
//alert(data);
$(function(){
$.ajax({
method : "GET",
url: "welcome",
data: {id: data},
success : function(response)
{
//debugger;
/*if(response==true)
alert("success");
else
alert("Failure");*/
var a=response;
//$('#fname').value(a.fname);
$('#firstName').val(a.fname);
$('#lastName').val(a.lname);
$('#qualification').val(a.qualification);
$('#emailAddress').val(a.email);
$('#contactmessage').val(a.desc);
var elem = document.getElementById("add");
elem.value="Update";
}
});
});
}
function disableData(data)
{
//alert(data);
//if (confirm('Are You Sure You Want To Delete Data ?')) {
$(function(){
$.ajax({
method : "GET",
url: "welcome/disable",
data: {id: data},
success : function(response)
{
//alert(response);
window.location.reload();
//debugger;
/*if(response==true)
alert("success");
else
alert("Failure");*/
//alert('Data is deleted Successfully!!!');
}
});
});
//} else {
//alert('Data is not deleted');
//}
}
function addUpdateData(data)
{
var btnvalue = document.getElementById("add").value;
//alert($('#firstName').val)
//alert(btnvalue);
if(btnvalue=="Add")
{
$(function(){
$.ajax({
method : "GET",
url: "welcome",
contentType: "application/json; charset=utf-8",
dataType: "json",
data: dataToSend,
success : function(response)
{
alert("data sent successfully");
//debugger;
/*if(response==true)

}
});
});
}
else

$.ajax({

Here is code for controller

use DB;
use App\Basicusers;
use Request;
use App\Http\Requests;
class FormController extends Controller
{
//$flag = "Add";
public function show()
{
//return 'FormController';
$forms = Basicusers::all()->where('flag',1);
//$name = ['Nix','Shiv'];
//return view('welcome',compact('name'));
return view('welcome',compact('forms'));
}
/*public function addNew(Request $req)
{
$bs = new Basicusers;

}*/
public function editdata()
{
//return "Editdata called";

//$flag = "Update";
//return view('edit',compact('data')));
$id = $_GET['id'];
//$id = Request::get();

return $data;
//return $id;

我可以使用以下命令获取数据
$id = $_GET['id'];//id of data to be disabled
$alldata = Basicusers::find($id);//row for which data will be disabled
$alldata->flag = 0;//setting values
$alldata->save();//saving data
return $alldata->flag;//returning new value
但是从上面的代码中，数据不会在数据库中更新 如何更新数据库中的数据请指导
点击删除按钮后，我只想禁用数据（不想获取该行） 我有一个名为flag的列，其中存储了二进制值0或1。
我只获取flag的值为1的记录
所以在删除时我想将该记录的标志值设为0
答案 0 :(得分：0)
也许您可以尝试替代laravel更新方法$alldata->update(['flag' => 0]);，看看你是否有更好的运气......
