警告：move_uploaded_file（）;未能打开流

问题描述：

我试图使用move_uploaded_file();警告：move_uploaded_file（）;未能打开流

$target_dir = "product_images/"; 
$target_file = $target_dir . basename($_FILES["product_image"]["name"]); 
if (move_uploaded_file($_FILES["product_image"]["tmp_name"], $target_file)) { // Line 92 
    echo "<script>alert('The file " . basename($_FILES["product_image"]["name"]) . " has been uploaded.')</script>"; 
} else { 
    echo "<script>alert('Sorry, there was an error uploading your file.')</script>"; 
    die(); 
}

所以要上传图片时，我尝试执行此代码我得到这个错误：

Warning: move_uploaded_file(product_images/img_forest.jpg): failed to open stream: Permission denied in /opt/lampp/htdocs/suvenirshop/admin_area/insert_product.php on line 92 

Warning: move_uploaded_file(): Unable to move '/opt/lampp/temp/phpZEJdEV' to 'product_images/img_forest.jpg' in /opt/lampp/htdocs/suvenirshop/admin_area/insert_product.php on line 92

我使用XAMPP Linux的，我也试过这个代码在Windows PC和MAC，我得到相同的错误。我不得不提，我有文件夹product_images在我存储insert_product.php执行此代码的文件夹中。

'权限denied'检查权限的'product_images'你工作，我改变了对文件夹的权限对所有要读写 –

谢谢现在它可以工作 –

答

尝试为product_images文件夹提供写入权限。在终端后藤在Linux系统中product_images文件夹中cd命令创建的文件夹，然后chmod a+w product_images命令
