Question

我有一个位于div元素中的文件上传。表单元素位于主文件中。 HasFile属性在第一次回发时始终返回false。

Asp.net代码

<div class="form-horizontal center-block" role="form" id="uploadFilesForm">
        <div class="form-group">
            <asp:Label runat="server" AssociatedControlID="fileUpload" CssClass="col-md-4 control-label">Select Files</asp:Label>
            <div class="col-md-8">
               <asp:FileUpload runat="server" ID="fileUpload" AllowMultiple="True" />                 
            </div>
        </div>  
        <div class="form-group">
            <asp:Label runat="server" CssClass="col-md-4 control-label"></asp:Label>
            <div class="col-md-8">
               <asp:Button runat="server" id="uploadButton" text="Upload"  CssClass="btn btn-primary" OnClick="uploadButton_Click"/>
            </div>
        </div>          
    </div>

C＃代码：

protected void Page_Load(object sender, EventArgs e)
{
   Page.Form.Enctype = "multipart/form-data";   
}
protected void uploadButton_Click(object sender, EventArgs e)
{
    if (fileUpload.HasFile) // this returns false on first postback
    {
    //more code
    }
}

在您的OnInit（）方法中添加以下代码：

public function organizations()
{
    return $this->belongsToMany('App\Models\Organization');
}

public function broadcasts()
{
    return $this->belongsToMany('App\Models\Broadcast');
}

Fileupload hasfile在第一次回发时返回false
