干预\Image\Exception\imagenotwriteableexception使用Laravel 4

我用的是Laravel4。我不知道为什么我会在一切似乎都是正确的情况下出现这个错误。此外，产品未更新到数据库

错误：干预\Image\Exception\ImageNotWritableException 无法将图像数据写入路径[/img/products/1396668877.jpg]

创建产品对象的ProductsController片段：

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();
}

传递到视图的产品对象

---

确保

public/img/products

文件夹存在且可写，如有必要，也尝试使用绝对路径，如下所示：

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

替换：

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

与：

您必须为

save

方法指定

public

文件夹。

工作正常！谢谢为什么绝对路径比相对路径有效。是因为它在本地服务器上吗？

    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();
            });
        }

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

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

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