javascript 普通形式的 Dropzone

Dropzone with normal form

提问by Tim Hartmann

My problem is that I must combine a normal form with dropzone.js for a drag&drop upload. After the user clicks the submit-button, then a ajax-request send the data to a php-script if there are values in the inputs.

我的问题是我必须将普通表单与 dropzone.js 结合起来进行拖放上传。在用户单击提交按钮后，如果输入中有值，ajax 请求会将数据发送到 php 脚本。

But how I can combine the files by dropzone and the ajax-request? I would send both, when the user clicks the button. If I drag a file in the zone than the file will be send.

但是我如何通过 dropzone 和 ajax 请求组合文件？当用户单击按钮时，我会同时发送两者。如果我在区域中拖动文件，则会发送该文件。

autoProcessQueue: false

This make it, that the file doesn't will be send if the user drag a file in the zone.

这样一来，如果用户在区域中拖动文件，则不会发送该文件。

Solution needed: User fills the form, drag a file in the zone and if the user click on the button, then the values and files will be send with a ajax-request.

需要的解决方案：用户填写表单，在区域中拖动一个文件，如果用户单击按钮，则值和文件将与 ajax 请求一起发送。

They have given what you want BUT there are some things to be added in what they have given like not making the whole form clickable and other things . The code below works fine for me

他们提供了您想要的东西，但是在他们提供的东西中还需要添加一些东西，例如不能使整个表单可点击和其他东西。下面的代码对我来说很好用

form.html

表单.html

<form method="post" action="upload.php" class="dropzone" id="mydropzone" enctype='multipart/form-data'> //remember we gave an id mydropzone to the form         
    <label>Username:<input type="text" name="uname"/> </label>
    <label>Password:<input type="text" name="pass"/> </label>
    //this will the dropzone drag and drop section.
    //notice we have given it an id dropzonePreview.
    <div id="dropzonePreview"></div>
    <input type="button" id="sbmtbtn" value="submit"/>
    //we have given id sbmtbtn to the button   
</form>
<script>
    Dropzone.options.mydropzone = {
    //url does not has to be written 
    //if we have wrote action in the form 
    //tag but i have mentioned here just for convenience sake 
        url: 'upload.php', 
        addRemoveLinks: true,
        autoProcessQueue: false, // this is important as you dont want form to be submitted unless you have clicked the submit button
        autoDiscover: false,
        paramName: 'pic', // this is optional Like this one will get accessed in php by writing $_FILE['pic'] // if you dont specify it then bydefault it taked 'file' as paramName eg: $_FILE['file'] 
        previewsContainer: '#dropzonePreview', // we specify on which div id we must show the files
        clickable: false, // this tells that the dropzone will not be clickable . we have to do it because v dont want the whole form to be clickable 
        accept: function(file, done) {
            console.log("uploaded");
            done();
        },
        error: function(file, msg){
            alert(msg);
        },
        init: function() {
            var myDropzone = this;
            //now we will submit the form when the button is clicked
            $("#sbmtbtn").on('click',function(e) {
               e.preventDefault();
               myDropzone.processQueue(); // this will submit your form to the specified action path
              // after this, your whole form will get submitted with all the inputs + your files and the php code will remain as usual 
        //REMEMBER you DON'T have to call ajax or anything by yourself, dropzone will take care of that
            });      
        } // init end
    };
</script>

NOTE: YOU DONT have to do any fancy stuff in the php file . Just write what you would normally write in PHP to upload files and input .

注意：您不必在 php 文件中做任何花哨的事情。只需编写您通常在 PHP 中编写的内容来上传文件和输入 .

See if this works for you.
