php - 上载图片错误

Question

大家好，我正在尝试将图像上传到指定目录，并且所有输出结果都是“上传文件时出错，请重试!”

$upload_dir = "blog/wp-content/uploads/products";    
if (file_exists($upload_dir) && is_writable($upload_dir)) {
    echo "Directory exists and is fine....";
}
else {
    echo "Upload directory is not writable, or does not exist.";
}

$target_path = "blog/wp-content/uploads/products/";

$target_path = $target_path . basename( $_FILES['image_file']['name']); 

if(move_uploaded_file($_FILES['image_file']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['image_file']['name']). 
    " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again!";

}

有任何想法吗？

Answer 1

如果未收到警告，则这是唯一的原因:If filename is not a valid upload file, then no action will occur, and move_uploaded_file() will return FALSE.文档中的引号。

使用.is_uploaded_file检查上传。
