如何使Dropzone.js只在单击Submit按钮时才上传文件？
如何使Dropzone.js只在单击Submit按钮时才上传文件？
提问于 2018-03-01 01:41:53
在过去的几天里，我一直在尝试将Dropzone实现到我的表单中，但是到目前为止，我还不知道如何让Dropzone上传和处理图像，只在单击Submit按钮时。所以，我决定来找你们帮忙。
我已经做了一个示例代码结构，我想要的是如何处理表单中的文件的提示/解决方案。将它们保存到文件夹中，并向数据库添加一个条目。
htdocs/application/Controller/test.php
<?php
class Test extends CI_Controller {
public function __construct() {
parent::__construct();
}
public function index() {
$this->load->view('test_view');
}
public function collect_input() {
}
}htdocs/application/controllers/test_view.php
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<meta charset="utf=8">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js" type="text/javascript"></script>
<!-- Load DropZone -->
<link href="<?php echo base_url(); ?>/css/basic.css" type="text/css" rel="stylesheet" />
<link href="<?php echo base_url(); ?>/css/dropzone.css" type="text/css" rel="stylesheet" />
<script src="<?php echo base_url(); ?>js/dropzone.min.js"></script>
<script type="text/javascript">
jQuery(document).ready(function()
{
var myDropzone = new Dropzone("div#myId", { url: "file-upload"});
});
</script>
<script type="text/javascript">
Dropzone.options.myId = {
// Prevents Dropzone from uploading dropped files immediately
autoProcessQueue: false,
init: function() {
var submitButton = document.querySelector("#add")
myDropzone = this; // closure
submitButton.addEventListener("click", function() {
myDropzone.processQueue(); // Tell Dropzone to process all queued files.
});
// You might want to show the submit button only when
// files are dropped here:
this.on("addedfile", function() {
// Show submit button here and/or inform user to click it.
});
}
};
</script>
</head>
<body>
<?php echo form_open('test/collect_input'); ?>
<!-- One of the many inputs of my form -->
<select id="list_type">
<option value="-1">Chooose a type</option>
<option value="1">>>Type A</option>
<option value="2">>>Type B</option>
</select>
<!-- Dropzone -->
<div id="myId" class="dropzone"></div>
<!-- Submit button-->
<input type="submit" id="add" name="add" value="Add!!">
</form>
</body>

Dropzone.autoDiscover = false;
jQuery(document).ready(function() {
var myDropzone = new Dropzone("#myId", {
url: 'someurl',
autoProcessQueue:false
});
$('#add').on('click',function(e){
e.preventDefault();
myDropzone.processQueue();
});

<script>
$(document).ready(function () {
Dropzone.options.dropzoneForm = {
autoProcessQueue: false
};
});
function processEvent() { // call this to trigger the upload
$('#dropzoneForm').get(0).dropzone.processQueue();
}
</script>
