这些是我所拥有的:

名为lamanInformasi的数据库表,其中包含名为isi的字段。

这就是我想要的:

用户可以上传多个文档或图像文件,这些文件将存储到数据库中。文件名将保存到 isi 字段,文件本身将保存到名为 propic 的文件夹中。用户还可以在网站上展示他们想要的文件并下载。

这就是我所做的:

我使用引导插件来输入文件。我用过这个source 。我只是使用了 js 和 css 文件夹中的文件。这是我的代码:

<html lang="en">
<head>
<meta charset="UTF-8"/>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css" rel="stylesheet">
<link href="../css/fileinput.css" media="all" rel="stylesheet" type="text/css" />
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">

<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="../js/fileinput.js" type="text/javascript"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js" type="text/javascript"></script>
</head>
<body>
<div class="container kv-main">
<div class="page-header">
<h1>Upload Files</h1>
</div>

<form enctype="multipart/form-data">
<div class="form-group">
<input id="file-5" class="file" type="file" multiple data-preview-file-type="any" data-upload-url="#">
</div>
</form>
</div>
</body>
<script>
$("#file-5").fileinput({
uploadUrl: "{{ url('lamanInformasi') }}",
uploadAsync: false,
previewFileIcon: '<i class="fa fa-file"></i>',
allowedPreviewTypes: 'image',
previewFileIconSettings: {
'doc': '<i class="fa fa-file-word-o text-primary"></i>',
'xls': '<i class="fa fa-file-excel-o text-success"></i>',
'ppt': '<i class="fa fa-file-powerpoint-o text-danger"></i>',
'jpg': '<i class="fa fa-file-photo-o text-warning"></i>',
'pdf': '<i class="fa fa-file-pdf-o text-danger"></i>',
'zip': '<i class="fa fa-file-archive-o text-muted"></i>',
'htm': '<i class="fa fa-file-code-o text-info"></i>',
'txt': '<i class="fa fa-file-text-o text-info"></i>',
'mov': '<i class="fa fa-file-movie-o text-warning"></i>',
'mp3': '<i class="fa fa-file-audio-o text-warning"></i>',
},
previewFileExtSettings: {
'doc': function(ext) {
return ext.match(/(doc|docx)$/i);
},
'xls': function(ext) {
return ext.match(/(xls|xlsx)$/i);
},
'ppt': function(ext) {
return ext.match(/(ppt|pptx)$/i);
},
'zip': function(ext) {
return ext.match(/(zip|rar|tar|gzip|gz|7z)$/i);
},
'htm': function(ext) {
return ext.match(/(php|js|css|htm|html)$/i);
},
'txt': function(ext) {
return ext.match(/(txt|ini|md)$/i);
},
'mov': function(ext) {
return ext.match(/(avi|mpg|mkv|mov|mp4|3gp|webm|wmv)$/i);
},
'mp3': function(ext) {
return ext.match(/(mp3|wav)$/i);
},
}
});
</script>

这是我的问题

如何将文件保存到数据库?如何在网站上显示文件?如何使文件可供下载?谢谢

最佳答案

您需要为文件输入字段指定一个名称,例如

<form enctype="multipart/form-data">
<div class="form-group">
<input id="file-5" name="image" class="file" type="file" multiple data-preview-file-type="any" data-upload-url="#">
</div>
</form>

然后在您的 Controller 方法中,您可以访问上传的文件并获取各种属性

**EDIT**
$destinationPath = storage_path().'/uploads/';
or
$destinationPath = public_path().'/uploads/';

//storage_path will give the fully qualified path to the storage folder
//public_path will give the fully qualified path to the public folder
//uploads - is the folder name where you want to store the user uploaded files, could be any name you prefer.
**EDIT end**

// Retrieving An Uploaded File
$file = Input::file('image');

// Determining If A File Was Uploaded
if (Input::hasFile('image'))
{
//
}

// Determining If An Uploaded File Is Valid
if (Input::file('image')->isValid())
{
//
}

// Moving An Uploaded File
Input::file('image')->move($destinationPath);
Input::file('image')->move($destinationPath, $fileName); //$filename is the name by which you want to store the file - change the name if required by by app.

// Getting Requested file path
$path = Input::file('image')->getRealPath();

// Getting Original name of the file
//**Edit** - gives the original filename as on uploading user's system. **Edit end**
$name = Input::file('image')->getClientOriginalName();

// Getting uploaded File extention
$extension = Input::file('image')->getClientOriginalExtension();

// Getting Size of the file
$size = Input::file('image')->getSize();

// Getting MIME Type of uploaded file
$mime = Input::file('image')->getMimeType();

然后,您可以通过与案例 lamanInformasi 中的数据库表相对应的 Model 将属性存储在数据库中,或者使用查询生成器直接使用原始数据存储到数据库表查询。

查看 Laravel 文档:
Database - query builder
Eloquent - model approach

您可以使用Laravel's filesystem从文件夹中检索文件并准备 ListView 供用户查看可供下载的文件。

然后使用可以杠杆Laravel's Response Download为用户提供下载功能。

希望这有帮助。
