Laravel 4 upload image form
提问by Ruben
I'm trying to make a form that allows uploading a file and store it in the public/upload folder of the application.
我正在尝试制作一个允许上传文件并将其存储在应用程序的 public/upload 文件夹中的表单。
my form is:
我的表格是：
<form action="/image/save" method="post">
<input name="image" type="file" />
<input type="submit" value="Save"/>
</form>
and the controller:
和控制器：
public function save(){
$file = Input::file('image');
$destinationPath = 'upload/';
$filename = $file->getClientOriginalName();
Input::file('image')->move($destinationPath, $filename);
But when I run it I get the following error:
Call to a member function getClientOriginalName()on a non-object
但是当我运行它时，我收到以下错误：调用getClientOriginalName()非对象上的成员函数

You need to have a file inputenabled on a form. (Doc)
In Laravel, you can use:
在 Laravel 中，您可以使用：
Form::open('image/save', array('files'=> true))
or
或者
<form action="/images/save" method="post" enctype="multipart/form-data">
Otherwise all you are receiving from the file input is the file name as a string.
否则，您从文件输入接收到的只是作为字符串的文件名。

If you not use Blade for generate your form like this
如果您不使用 Blade 生成这样的表单
{{ Form::open(array('url' => 'foo/bar', 'files' => true)) }}
Just add this parameter to your form tag
只需将此参数添加到您的表单标签中
enctype="multipart/form-data"

I also faced the same problem with one of my forms, the problem was the form wasn't defined with the option, 'files' => true, which tells the Laravel4 form helper to define a form with enctype="multipart/form-data"
我的一个表单也遇到了同样的问题，问题是表单没有用选项定义，'files' => true，它告诉 Laravel4 表单助手定义一个表单enctype="multipart/form-data"
Here is what i did:
这是我所做的：
Define the following array in your controller and pass it to your view ,
在您的控制器中定义以下数组并将其传递给您的视图，
$form_options = array (
'url' => 'path/to/defined/route',
'class' => 'form-horizontal',
'name' => 'newUser',
'files' => true
);
In your view, define your form as follows:
在您看来，请按如下方式定义您的表单：
{{ Form::open( $form_options ) }}
That will define your form with enctype="multipart/form-data"
这将定义您的表单 enctype="multipart/form-data"

You have to get the filename as follows:
您必须按如下方式获取文件名：
//Blade form
{{ Form::open_for_files('/image/save') }}
{{ Form::file('image') }}
{{ Form::close() }}
//get imagename
$filename = Input::file('image.name');
Good luck! :)
祝你好运！:)

You can just add the field 'files'=> truein your array()if you use Laravel form style something like
如果您使用 Laravel 表单样式，则可以'files'=> true在您的字段中添加该字段array()
{{ Form::open(array('url'=>'/images/save','role'=>'form','files'=> true)) }}
otherwise you can use the html form tag something like
否则你可以使用html表单标签之类的
<form action="/images/save" method="post" enctype="multipart/form-data">
Hope this will help you.
希望这会帮助你。
