Question

我有这种简化的情况：

<form action='process.php' method='post'>

<div class="dropzone no-margin">
    <div class="fallback">
        <input name="file" type="file" multiple/>
    </div>
</div>

</form>

$(".dropzone").dropzone({ 
url: "/test2.php",
maxFilesize: 2,
maxFiles: 5
});

test2.php工作得很好，它会立即上传丢弃在dropzone上的文件。但是，问题是，我需要将上传文件的文件名作为隐藏文本输入传递给表单。

这里的test2.php看起来像是：

<?php
$target_dir = "user/product/";
$target_file = $target_dir . basename($_FILES["file"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["file"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["file"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["file"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
?>

我是javascript或jquery世界的初学者。所以，我真的需要你的帮助，让我知道如何将文件名作为隐藏文本输入传递给表单，以便以后可以将其写入数据库。

非常感谢你，我真的很感谢你的帮助。

试试这个：

在Dropzone中有一种方法，即发送，用于在发送文件之前发送数据。如果上传了多个文件，则使用 sendingmultiple 方法。

$(".dropzone").dropzone({ 
   url: "/test2.php",
   maxFilesize: 2,
   maxFiles: 5,
   sending:function (data, xhr, formdata) {
      console.log("data :",data);
      //here you can get file name from data variable.you can add that to your form by following line.
      formdata.append('hidden field name', 'file name');
      //you can add as much parameter you want to pass to your post data by formdata.append() function. That will add data to your form data.you can refer that value by using $_POST['hidden_field_name'] at PHP side.
    }
});
