我有一个表单，可以非常简单地将图像文件上传到帖子中，它使用图像干预
"intervention/image": "dev-master"
所以我可以调整它的大小等，但目前这是一个简单的后期操作，比如：
<?php namespace Boroughcc'Http'Controllers;
use Input;
use Redirect;
use Storage;
use SirTrevorJs;
use STConverter;
use Validator;
use Image;
use Boroughcc'Post;
use Boroughcc'Http'Requests;
use Boroughcc'Http'Controllers'Controller;
use Illuminate'Http'Request;
class PostsController extends Controller {
public function store()
{
// image upload function
// $img = Image::make(Input::file('featured_image'));
// dd($img);
$input = Input::all();
$validation = Validator::make($input, Post::$rules);
$entry = array(
'title' => Input::get('title'),
'featured_image' => Input::file('featured_image')
);
if ($validation->passes())
{
$img = Image::make(Input::file('featured_image'));
$pathinfo = pathinfo($img);
$type = $pathinfo['basename'];
$filename = date('Y-m-d-H:i:s').$type;
$path = 'img/posts/' . $filename;
$img->save($path);
$post = Post::create(
$entry
);
return Redirect::route('posts.index')->with('message', 'Post created');
} else {
return Redirect::route('posts.create')
->withInput()
->withErrors($validation)
->with('message', 'There were validation errors.');
}
//Post::create( $input );
// return Redirect::route('posts.index')->with('message', 'Post created');
}
post检查验证，如果所有验证都正确，它会发送post来保存它，并有望生成文件。当它保存它时，文件会很好地进入我的/public/img/posts/文件夹。下面是后模型；
Post.php
<?php namespace Boroughcc;
use Illuminate'Database'Eloquent'Model;
class Post extends Model {
//
protected $guarded = [];
public static $rules = array(
'title' => 'required',
'featured_image' => 'required|image|mimes:jpeg,jpg,png,bmp,gif,svg'
);
}
所以你可以看到我试图在这里输出的是我在post.index页面中使用的图像url：
{!! Form::model(new Boroughcc'Post, ['route' => ['posts.store'], 'files' => true]) !!}
<div class="form-group">
{!! Form::label('title', 'Title:') !!}
{!! Form::text('title') !!}
</div>
<div class="form-group">
<strong>Only edit this if necessary, this is auto populated</strong><br>
{!! Form::label('slug', 'Slug:') !!}
{!! Form::text('slug') !!}
</div>
<div class="form-group">
{!! Form::label('featured_image', 'Featured Image:') !!}
{!! Form::file('featured_image') !!}
</div>
<div class="form-group">
{!! Form::label('body', 'Post body:') !!}
{!! Form::textarea('body', null, array('id'=>'','class'=>'sir-trevor')) !!}
</div>
<div class="form-group">
{!! Form::submit($submit_text, ['class'=>'btn primary']) !!}
</div>
{!! Form::close() !!}
当我去获取要输出的文件url时，我得到的是：
"featured_image" => "/private/var/folders/mf/srx7jt8s2rdg0mn5hr98cvz80000gn/T/phpMEtuuA"
这就是我所得到的，这有什么问题吗？为什么它只渲染这个？
在Laravel中上传文件时，通过Input::file方法访问该文件将返回Symfony'Component'HttpFoundation'File'UploadedFile的实例，因此分配'featured_image' => Input::file('featured_image')将不起作用。
因此，与其在将文件保存到磁盘之前构建$entry细节数组，不如实际生成图像路径和文件名，并将其存储在数据库中。此外，除非您想以任何方式调整图像大小或操作图像，否则无需使用干预库。这应该做得很好：
// Get the uploaded file object
$image = Input::file('featured_image');
// Generate the necessary file details
$extension = pathinfo($image->getClientOriginalName(), PATHINFO_EXTENSION);
$filename = date('Y-m-d-H:i:s') . '.' . $extension;
$path = 'img/posts/';
// Move the uploaded image to the specified path
// using the generated specified filename
$image->move($path, $filename);
// Save the post to the database
// using the path and filename use above
$post = Post::create(array(
'title' => Input::get('title'),
'featured_image' => $path . $filename
));
