Hi All,
I am attempting to create a form where a user is able to enter your typical form values textboxes etc, but also upload a file as part of the form submission. This is my View code it can be seen that the File upload is identified by the MCF id:
<% using (Html.BeginForm("Create", "Problem", FormMethod.Post,
new { id = "ProblemForm", enctype = "multipart/form-data" }))
{%>
<p>
<label for="StudentEmail">Student Email (*)</label>
<br />
<%= Html.TextBox("StudentEmail", Model.Problem.StudentEmail,
new { size = "30", maxlength=26 })%>
<%= Html.ValidationMessage("StudentEmail", "*") %>
</p>
<p>
<label for="Type">Communication Type (*)</label>
<br />
<%= Html.DropDownList("Type") %>
<%= Html.ValidationMessage("Type", "*") %>
</p>
<p>
<label for="ProblemDateTime">Problem Date (*)</label>
<br />
<%= Html.TextBox("ProblemDateTime", String.Format("{0:d}", Model.Problem.ProblemDateTime),
new { maxlength = 10 })%>
<%= Html.ValidationMessage("ProblemDateTime", "*") %>
</p>
<p>
<label for="ProblemCategory">Problem Category (* OR Problem Outline)</label>
<br />
<%= Html.DropDownList("ProblemCategory", null, "Please Select...")%>
<%= Html.ValidationMessage("ProblemCategory", "*")%>
</p>
<p>
<label for="ProblemOutline">Problem Outline (* OR Problem Category)</label>
<br />
<%= Html.TextArea("ProblemOutline", Model.Problem.ProblemOutline, 6, 75,
new { maxlength = 255 })%>
<%= Html.ValidationMessage("ProblemOutline", "*") %>
</p>
<p>
<label for="MCF">Mitigating Circumstance Form</label>
<br />
<input id="MCF" type="file" />
<%= Html.ValidationMessage("MCF", "*") %>
</p>
<p>
<label for="MCL">Mitigating Circumstance Level</label>
<br />
<%= Html.DropDownList("MCL") %>
<%= Html.ValidationMessage("MCL", "*") %>
</p>
<p>
<label for="AbsentFrom">Date Absent From</label>
<br />
<%= Html.TextBox("AbsentFrom", String.Format("{0:d}", Model.Problem.AbsentFrom),
new { maxlength = 10 })%>
<%= Html.ValidationMessage("AbsentFrom", "*") %>
</p>
<p>
<label for="AbsentUntil">Date Absent Until</label>
<br />
<%= Html.TextBox("AbsentUntil", String.Format("{0:d}", Model.Problem.AbsentUntil),
new { maxlength = 10 })%>
<%= Html.ValidationMessage("AbsentUntil", "*") %>
</p>
<p>
<label for="AssessmentID">Assessment Extension</label>
<br />
<%= Html.DropDownList("AssessmentID") %>
<%= Html.ValidationMessage("AssessmentID", "*") %>
<%= Html.TextBox("DateUntil", String.Format("{0:d}", Model.AssessmentExtension.DateUntil),
new { maxlength = 16 })%>
<%= Html.ValidationMessage("DateUntil", "*") %>
</p>
<p>
<label for="Details">Assessment Extension Details</label>
<br />
<%= Html.TextArea("Details", Model.AssessmentExtension.Details, 6, 75,
new { maxlength = 255 })%>
<%= Html.ValidationMessage("Details", "*") %>
</p>
<p>
<label for="RequestedFollowUp">Requested Follow Up</label>
<br />
<%= Html.TextBox("RequestedFollowUp", String.Format("{0:d}", Model.Problem.RequestedFollowUp),
new { maxlength = 16 })%>
<%= Html.ValidationMessage("RequestedFollowUp", "*") %>
</p>
<p>
<label for="StaffEmail">Staff</label>
<br />
<%= Html.ListBox("StaffEmail", Model.StaffEmail,
new { @class = "multiselect" })%>
<%= Html.ValidationMessage("StaffEmail", "*")%>
</p>
<p>
<input class="button" type="submit" value="Create Problem" />
</p>
This is my controller code:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(Problem problem, AssessmentExtension assessmentExtension, Staff staffMember, HttpPostedFileBase file, string[] StaffEmail)
{
if (ModelState.IsValid)
{
try
{
Student student = studentRepository.GetStudent(problem.StudentEmail);
Staff currentUserStaffMember = staffRepository.GetStaffWindowsLogon(User.Identity.Name);
var fileName = Path.Combine(Request.MapPath("~/App_Data"), Path.GetFileName(file.FileName));
file.SaveAs(@"C:\Temp\" + fileName);
if (problem.RequestedFollowUp.HasValue)
{
String meetingName = student.FirstName + " " + student.LastName + " " + "Mitigating Circumstance Meeting";
OutlookAppointment outlookAppointment =
new OutlookAppointment(currentUserStaffMember.Email, meetingName, (DateTime)problem.RequestedFollowUp, (DateTime)problem.RequestedFollowUp.Value.AddMinutes(30));
}
problemRepository.Add(problem);
problemRepository.Save();
if (assessmentExtension.DateUntil != null)
{
assessmentExtension.ProblemID = problem.ProblemID;
assessmentExtensionRepository.Add(assessmentExtension);
assessmentExtensionRepository.Save();
}
ProblemPrivacy problemPrivacy =
new ProblemPrivacy();
problemPrivacy.ProblemID = problem.ProblemID;
problemPrivacy.StaffEmail = currentUserStaffMember.Email;
problemPrivacyRepository.Add(problemPrivacy);
if (StaffEmail != null)
{
for (int i = 0; i < StaffEmail.Length; i++)
{
ProblemPrivacy probPrivacy =
new ProblemPrivacy();
probPrivacy.ProblemID = problem.ProblemID;
probPrivacy.StaffEmail = StaffEmail[i];
problemPrivacyRepository.Add(probPrivacy);
}
}
problemPrivacyRepository.Save();
return RedirectToAction("Details", "Student",
new { id = student.Email });
}
catch
{
ModelState.AddRuleViolations(problem.GetRuleViolations());
}
}
return View(new ProblemFormViewModel(problem, assessmentExtension, staffMember));
}
This form was working correctly before I had to switch to using a non-AJAX file upload, this was due to an issue with Flash when enabling Windows Authentication which I need to use.
It appears that when I submit the form the file is not sent and I am unsure as to why? I have also been unsuccessful in finding an example online where a file upload is used in conjunction with other input types.
Another query I have is that for Create, and Edit operations I have used a PartialView for my forms to make my application have higher code reuse. The form action is normally generated by just using:
Html.BeginForm()
And this populates the action depending on which Url is being used Edit or Create. However when populating HTML attributes you have to provide a action and controller value to pass HTML attributes.
using (Html.BeginForm("Create", "Problem", FormMethod.Post,
new { id = "ProblemForm", enctype = "multipart/form-data" }))
Is it possible to somehow populate the action and controller value depending on the URL to maintain code reuse? Thinking about it whilst typing this I could set two values in the original controller action request view data and then just populate the value using the viewdata values?
Any help on these two issues would be appreciated, I'm
new to asp.net mvc :-)
Thanks,
Jon
