【问题描述】：

我正在使用 Laravel 4。当一切似乎都正确时，我不确定为什么会出现此错误。此外，该产品未更新到数据库。

错误：Intervention\Image\Exception\ImageNotWritableException 无法将图片数据写入路径[/img/products/1396668877.jpg]

ProductsController 的片段，其中产品对象被创建：

public function postCreate() 
    $validator = Validator::make(Input::all(), Product::$rules);

    if ($validator->passes()) 
        $product = new Product;
        $product->category_id = Input::get('category_id');
        $product->title = Input::get('title');
        $product->description = Input::get('description');
        $product->price = Input::get('price');

        $image = Input::file('image');
        $filename  = time() . '.' . $image->getClientOriginalExtension();
        Image::make($image->getRealPath())->resize(468, 249)->save('/img/products/'.$filename);
        $product->image = 'img/products/'.$filename;
        $product->save();

        return Redirect::to('admin/products/index')
            ->with('message', 'Product Created');
    

    return Redirect::to('admin/products/index')
        ->with('message', 'Something went wrong')
        ->withErrors($validator)
        ->withInput();

传递给视图

的产品对象

@foreach($products as $product)
                <li>
                     html::image($product->image, $product->title, array('width'=>'50'))  
                     $product->title  - 
                     Form::open(array('url'=>'admin/products/destroy', 'class'=>'form-inline')) 
                     Form::hidden('id', $product->id) 
                     Form::submit('delete') 
                     Form::close()  - 

                 Form::open(array('url'=>'admin/products/toggle-availability', 'class'=>'form-inline'))
                 Form::hidden('id', $product->id) 
                 Form::select('availability', array('1'=>'In Stock', '0'=>'Out of Stock'), $product->availability) 
                 Form::submit('Update') 
                 Form::close() 
            </li>
        @endforeach

产品型号

<?php

class Product extends Eloquent 

    protected $fillable = array('category_id', 'title', 'description', 'price', 'availability', 'image');

    public static $rules = array(
        'category_id'=>'required|integer',
        'title'=>'required|min:2',
        'description'=>'required|min:20',
        'price'=>'required|numeric',
        'availability'=>'integer',
        'image'=>'required|image|mimes:jpeg,jpg,bmp,png,gif'
    );

    public function category() 
        return $this->belongsTo('Category');
    

数据库

中的

products表

    public function up()
        
            Schema::create('products', function($table)
                $table->increments('id');
                $table->integer('category_id')->unsigned();
                $table->foreign('category_id')->references('id')->on('categories');
                $table->string('title');
                $table->text('description');
                $table->decimal('price', 6, 2);
                $table->boolean('availability')->default(1);
                $table->string('image');
                $table->timestamps();
            );
        

【参考方案1】：

确保public/img/products 文件夹存在且可写，如有必要，请尝试使用绝对路径，如下所示：

$filename  = time() . '.' . $image->getClientOriginalExtension();
$path = public_path('img/products/' . $filename);
Image::make($image->getRealPath())->resize(468, 249)->save($path);

【讨论】：

完美运行！谢谢。为什么绝对路径优于相对路径。是因为它在本地服务器上吗？

【参考方案2】：

替换：

Image::make($image->getRealPath())->resize(468, 249)->save('/img/products/'.$filename);

与：

Image::make($image->getRealPath())->resize(468, 249)->save('public/img/products/'.$filename);

您必须为save 方法指定public 文件夹。
