我想在我的dropzone文件上传器中添加一个按钮上传。目前,在选择或拖动文件到dropzone区域后,它会直接上传文件。我想做的是: 1.选择或暂停要上载的文件。 2.验证 3.点击或按下上传按钮上传文件。
N.B:按下按钮上传后才会上传文件。
这是我的表格
<form id='frmTarget' name='dropzone' action='upload_files.php' class='dropzone'>
<div class='fallback'>
<input name='file' type='file' multiple />
</div>
<input id='refCampaignID' name='refCampaignID' type='hidden' value=\ "$rowCampaign->CampaignID\" />
</form>
这是我的JS
Dropzone.options.frmTarget =
{
url: 'upload_files.php',
paramName: 'file',
clickable: true,
maxFilesize: 5,
uploadMultiple: true,
maxFiles: 2,
addRemoveLinks: true,
acceptedFiles: '.png,.jpg,.pdf',
dictDefaultMessage: 'Upload your files here',
success: function(file, response)
{
setTimeout(function() {
$('#insert_pic_div').hide();
$('#startEditingDiv').show();
}, 2000);
}
};
这是我的php帖子请求
foreach ($_FILES["file"] as $key => $arrDetail)
{
foreach ($arrDetail as $index => $detail) {
//print_rr($_FILES["file"][$key][$index]);
$targetDir = "project_images/";
$fileName = $_FILES["file"]['name'][$index];
$targetFile = $targetDir.$fileName;
if(move_uploaded_file($_FILES["file"]['tmp_name'][$index],$targetFile))
{
$db = new ZoriDatabase("tblTarget", $_REQUEST["TargetID"], null, 0);
$db->Fields["refCampaignID"] = $_REQUEST["refCampaignID"];
$db->Fields["strPicture"] = $fileName;
$db->Fields["blnActive"] = 1;
$db->Fields["strLastUser"] = $_SESSION[USER]->USERNAME;
$result = $db->Save();
if($result->Error == 1){
return "Details not saved.";
}else{
return "Details saved.";
}
}else{
return "File not uploaded.";
}
}
}

你需要:
添加按钮:
return nil
告知Dropzone 不在删除文件时自动上传文件,默认情况下会这样。这是通过the autoProcessQueue
config option完成的:
<button type="submit" id="button" class="btn btn-primary">Submit</button>
由于Dropzone现在不会自动上传文件,因此您需要在单击按钮时手动告诉它执行此操作。所以你需要一个事件处理程序来点击该按钮,告诉Dropzone进行上传:
autoProcessQueue: false
这只是POST上传的文件,没有任何其他输入字段。您可能希望发布所有字段,例如您的$("#button").click(function (e) {
e.preventDefault();
myDropzone.processQueue();
});
,如果您有一个CSRF令牌,等等。为此,您需要在发送之前将它们复制到POST中。 Dropzone有一个sending
event,它在每个文件发送之前调用,您可以在其中添加回调:
refCampaignID
全部放在一起:
this.on('sending', function(file, xhr, formData) {
// Append all form inputs to the formData Dropzone will POST
var data = $('form').serializeArray();
$.each(data, function(key, el) {
formData.append(el.name, el.value);
});
});

还应该添加一个纯香草JS解决方案,而不使用jQuery。
/* 'dropform' is a camelized version of your dropzone form's ID */
Dropzone.options.dropform = {
/* Add all your configuration here */
autoProcessQueue: false,
init: function()
{
let myDropzone = this;
/* 'submit-dropzone-btn' is the ID of the form submit button */
document.getElementById('submit-dropzone-btn').addEventListener("click", function (e) {
e.preventDefault();
myDropzone.processQueue();
});
this.on('sending', function(file, xhr, formData)
{
/* OPTION 1 (not recommended): Construct key/value pairs from inputs in the form to be sent off via new FormData
'dropform' is the ID of your dropzone form
This method still works, but it's submitting a new form instance. */
formData = new FormData(document.getElementById('dropform'));
/* OPTION 2: Append inputs to FormData */
formData.append("input-name", document.getElementById('input-id').value);
});
}
};
注意::设置事件监听器(例如我们在此处执行的sending
监听器)应放在init
函数内。如果要将它们放置在其他位置,例如:
init: function()
{
//...
},
sending: function(file, xhr, formData)
{
//... logic before each file send
}
这将覆盖为sending
事件侦听器提供的默认逻辑dropzone,并且可能导致意外的副作用。只有知道自己在做什么,才应该这样做。

对于 Vue Js
如果没有安装,请安装 vue2-dropzone
关于你想要的组件:
<div class="form-group">
<label for="">Product Name</label>
<input type="text" v-model="product_name" placeholder="Product Name" class="form-control">
</div>
<div class="form-group">
<label for="">Product SKU</label>
<input type="text" v-model="product_sku" placeholder="sku" class="form-control">
</div>
<div class="card shadow mb-4">
<div class="card-header py-3 d-flex flex-row align-items-center justify-content-between">
<h6 class="m-0 font-weight-bold text-primary">Media</h6>
</div>
<div class="card-body border">
<vue-dropzone ref="myVueDropzone" id="dropzone" :options="dropzoneOptions" v-on:vdropzone-sending="sendingEvent"></vue-dropzone>
</div>
</div>
保存按钮:
<button @click="saveProduct" type="submit" class="btn btn-lg btn-primary">Save</button>
在脚本标签内
import vue2Dropzone from 'vue2-dropzone'
导入'vue2-dropzone/dist/vue2Dropzone.min.css'
data() {
return {
product_name: '',
product_sku: '',
dropzoneOptions: {
url: "/product/images",
thumbnailWidth: 150,
maxFilesize: 0.5,
addRemoveLinks: true,
autoProcessQueue:false,
uploadMultiple:true,
headers: {"X-CSRF-TOKEN": document.querySelector('meta[name="csrf-token"]').getAttribute('content')}
}
}
},
methods: {
saveProduct() {
this.$refs.myVueDropzone.processQueue();
},
sendingEvent (file, xhr, formData) {
formData.append("title", this.product_name);
formData.append("sku", this.product_sku);
console.log(formData);
}
}
