I have this controller and what I am trying to do is to send an image to the controller as a [byte], this is my controller:
[HttpPost]
public ActionResult AddEquipment(Product product, HttpPostedFileBase image)
{
if (image != null)
{
product.ImageMimeType = image.ContentType;
product.ImageData = new byte[image.ContentLength];
image.InputStream.Read(product.ImageData, 0, image.ContentLength);
}
_db.Products.Add(product);
_db.SaveChanges();
return View();
}
and on my view:
@using (Html.BeginForm("AddEquipment", "Equipment", FormMethod.Post)) {
<fieldset>
<legend>Product</legend>
<div class="editor-label">
@Html.LabelFor(model => model.Name)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Name)
@Html.ValidationMessageFor(model => model.Name)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Description)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Description)
@Html.ValidationMessageFor(model => model.Description)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Price)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Price)
@Html.ValidationMessageFor(model => model.Price)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Category)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Category)
@Html.ValidationMessageFor(model => model.Category)
</div>
<div>
<div>IMAGE</div>
<input type="file" name="image" />
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}
but the problem is that on my controller the value for image is alway null, I cant seem to get any information on the HttpPostedFileBase
You need to add the encType
with multipart/form-data.
@using (Html.BeginForm("AddEquipment", "Equipment", FormMethod.Post, new {enctype = "multipart/form-data" })) {
You can always add it to your model too as follows, providing it is a ViewModel:
public class Product
{
public Product()
{
Files = new List<HttpPostedFileBase>();
}
public List<HttpPostedFileBase> Files { get; set; }
// Rest of model details
}
You can the retrieve the files by removing the un-needed parameter ie
[HttpPost]
public ActionResult AddEquipment(Product product)
{
var file = model.Files[0];
...
}
Try to do this at the top of the Action method:
[HttpPost]
public ActionResult AddEquipment(Product product, HttpPostedFileBase image)
{
image = image ?? Request.Files["image"];
// the rest of your code
}
And the form should have enctype of "multipart/form-data" to upload files:
@using (Html.BeginForm("AddEquipment", "Equipment", FormMethod.Post, new {enctype = "multipart/form-data" })) {
