$ _FILES [“image”] [“tmp_name”]是empy没有数据

Question

我写了下面的代码。但是我没有价值的空$_FILES[“image”][“tmp_name”]。

PHP的：

if ($_FILES) { 
$imageFileType = strtolower(pathinfo("img/" . basename($_FILES["Image"]["name"]), PATHINFO_EXTENSION)); 

$target_file = "img/" . uniqid(rand()) . ".$imageFileType"; 
if (move_uploaded_file($_FILES["Image"]["tmp_name"], $target_file)) { 
    $pic = $target_file;  
} else { 

    echo "Invalid File"; 
    } 
} 

HTML：

<form action="product-add.php" method="post" enctype="multipart/form-data"> 
     <div class="products-form"> 
      <p> Image:</p> <input type="file" name="Image" > 
      <input type="submit" value="ADD PRODUCT" class="btn"> 
     </div> 
</form> 

Answer 1

那么在我看来，这是不对的：

$target_file = "img/" . uniqid(rand()) . ".$imageFileType"; 

应该

$target_file = "img/" . uniqid(rand()) . "." .$imageFileType;
