"Not working" is not very informative.
Try to find out where the problems are located (creating the mail or sending it).
Note that using PHP: mail - Manual[^] requires proper setup in php.ini and sendmail.ini.
Some SMTP servers have specific requirements which must be met. You are using HotMail. So a research about "php mail hotmail" might help.
Finally you might also think about replacing the build-in mail support by an additional module like GitHub - PHPMailer/PHPMailer: The classic email sending library for PHP[^]. These provide you with detailed error messages (SMTP error codes) while the build-in function only returns a boolean value.

I posted this in the Lounge yesterday. I'm feeling pretty good about getting my app working.
Then Sander asked this question, so I thought I'd start this thread to get more info.
Thanks for pointing out my folly Sander. 
Here is the JavaScript code that I have now. It listens to a SignalR service, which notifies it when a record is changed. Right now I have an ajax call that refreshes the whole grid. Ya, bad idea.. but I just wanted to get it working.
<script src="/Scripts/jquery-3.1.1.min.js"></script>
<script src="/Scripts/jquery.signalR-2.1.2.js"></script>
<script src="~/signalr/hubs"></script>
<script type="text/javascript">
$(function () {
<pre>
var conn = $.hubConnection("http://blah:8094/signalr");
var proxy = conn.createHubProxy('dashboardHub')
proxy.on('notifyAllClientsOfChanges', function () {
var searchUrl = "Index/GetData";
$.ajax({
url: searchUrl,
type: "POST",
success: function (data) {
$("#divData").html(data);
}
});
});
conn.start().done(function ()
{
console.log("Connected!!!");
}).fail(function (e)
{
console.log('Unable to connect:' + e);
});
});
So, what I'd really like is to pass the updated record through the notifyAllClientsOfChanges method into the code above and have it add the record to the WebGrid, or update it of it already exists.
I'm very new to this, so can anyone point me in the right direction? Any examples of doing this?
Thanks

You'll need to change your back-end as well.
I've once created some example with some stock and put it on GitHub (GitHub - SanderRossel/starting-signalr: Examples on how to use SignalR.[^]).
You can checkout the StockHub.cs[^] file and the Index.js[^] files.
The important parts are these:
StockHub.cs
Clients.All.updateAmount(id, newAmount); Index.js
stockHub.client.updateAmount = function (id, amount) {
var product = stock().filter(function (p) { return p.id === id })[0];
if (product) {
product.amount(amount);
}
};As you can see I'm passing some data from C# to JavaScript so I can just process it in JavaScript.
I'm not sure how that works out for your example, but you could put whatever data Index/GetData returns into your SignalR function to pass to your front-end.
Hope that helps, good luck

I'm back on this project now. In your JS code above you have:
var product = stock().filter(function (p) { return p.id === id })[0];
I'm guessing it trying to find the data row, but I don't understand the syntax. Can you please explain it to me?

From the top of my head, stock() returns an array, which has a filter() function.
The filter() function takes a predicate as parameter, which is simply a function that returns true or false for each element p in the array.
In this case the predicate (function (p) { ... }) returns true when element p.id === id (where the id variable declaration is not visible in this code sample).
The filter function returns a new array containing all elements for which the predicate returned true.
From that array I'm selecting the 0th element (since an id is unique we expect 0 or 1 elements to be returned).

OK, I see, except for stock(). What is stock()? Looks like a method call..?

I've got a javaScript function that handles a SignalR callback:
proxy.on('notifyAllClientsOfChanges', function () {
var searchUrl = "Home/GetData";
$.ajax({
url: searchUrl,
type: "GET",
success: function (data) {
$("#divData").html(data);
}
});
});
When it's called I get the 404. My controller code is
public class HomeController : Controller
{
private IDataAccess _dal;
public HomeController()
{
_dal = new DataAccess();
}
public ActionResult Index()
{
var data = GetData();
return View(data);
}
public IEnumerable<AssayDashboardInfoEntity> GetData()
{
IEnumerable<AssayDashboardInfoEntity> data = _dal.GetDashboardInfos(new DashboardInfoQueryArgs());
return data;
}
}
On startup the code works fine and I see the data, yet when the JS function is called it fails.
If it's not broken, fix it until it is.

If it's 404 then it can't find "Home/GetData". We don't have access to your system so we have no way of knowing what that is. If I had to guess I'd say it's because "Home/GetData" is a relative path so it is relative to the current page, so if you are on
/Home/MyAction
then it is trying to call
/Home/MyAction/Home/GetData
you can fix that by changing the action to "/Home/GetData", however you should really be using @Url.Action to get the urls to your actions as it works all these issues out for you.

Hi, I'm going to be applying for a school very soon, and I need some ideas for a front page for my website to show the school. The problem is, I'm not very creative, and can't think of any real projects to display on the front page. Can anybody give me any ideas on what I can put on my front page to make it look good? (The code for the website isn't a problem).
Thanks

I have this WebGrid. When I run this from inside Visual Studio it works fine. When I host on IIS I get "A data source must be bound before this operation can be performed".
@using (@Html.BeginForm("Index", "Home"))
{
<div id="divData">
@{
var grid = new WebGrid(Model);
<pre>
@grid.GetHtml(
tableStyle: "webgrid-table",
headerStyle: "webgrid-header",
footerStyle: "webgrid-footer",
alternatingRowStyle: "webgrid-alternating-row",
selectedRowStyle: "webgrid-selected-row",
rowStyle: "webgrid-row-style",
mode: WebGridPagerModes.All,
columns:
grid.Columns
(
grid.Column(columnName: "SiteId", header: "Site Id", format: @<text>@item.SiteId</text>),
grid.Column(columnName: "Instrument", header: "Instrument", format: @<text>@item.InstrumentId</text> ),
grid.Column(columnName: "TowerLocation", header: "Tower", format: @<text>@item.TowerLocation</text>),
grid.Column(columnName: "BayLocation", header: "Bay Location", format: @<text>@item.BayLocation</text>),
grid.Column(columnName: "BaySerialNo", header: "Bay Serial #", format: @<text>@item.BaySerialNo</text>),
grid.Column(columnName: "BayStatus", header: "Bay Status", format: @<text>@item.BayStatus</text>),
grid.Column(columnName: "AccessionId", header: "Accession ID", format: @<text>@item.AccessionId</text>),
grid.Column(columnName: "Result", header: "Result", format: @<text>@item.Result</text>),

grid.Column(columnName: "TestCompleted", header: "Completed", format: @<text>@item.Completed</text>),
grid.Column(columnName: "TestSummary", header: "Test Summary", format: @<text>@item.TestSummary</text> )
))
}
}
I see this error
Line 127: var grid = new WebGrid(Model);
Line 128:
Line 129: @grid.GetHtml(
Line 130: tableStyle: "webgrid-table",
Line 131: headerStyle: "webgrid-header",
The line highlited in the browser is where it's failing.
The Controller code
public class HomeController : Controller
{
private IDataAccess _dal;
public HomeController()
{
_dal = new DataAccess();
}
public ActionResult Index()
{
var data = GetData();
return View(data);
}
public IEnumerable<AssayDashboardInfoEntity> GetData()
{
var data = _dal.GetDashboardInfos(new DashboardInfoQueryArgs());
return data;
}
}
What am I doing wrong here?
[UPDATE]
In the controller if I change
IEnumerable<AssayDashboardInfoEntity> data = _dal.GetDashboardInfos(new DashboardInfoQueryArgs());
to
IEnumerable<AssayDashboardInfoEntity> data = new List<AssayDashboardInfoEntity>();
The I see the grid OK. This makes me think it's not reaching the server for the data. How can I test this?

It sounds like your GetDashboardInfos method is returning an unevaluated LINQ query, and then closing the context / connection before the grid is rendered.
Try adding .ToList() to force the query to be evaluated:
IEnumerable<AssayDashboardInfoEntity> data = _dal.GetDashboardInfos(new DashboardInfoQueryArgs()).ToList();

Well, figured it out...
After some debugging I found that the DAL was returning NULL.. Kept digging and found that the Connection String was wrong.
