Summernote v0.8.1的图像上传

Question

编辑器Summernote存在问题。我想将图像上传到服务器上的目录中。我有一些脚本：

<script type="text/javascript">
  $(function () {
    $(\'.summernote\').summernote({
      height: 200
    });
    $(\'.summernote\').summernote({
     height:300,
     onImageUpload: function(files, editor, welEditable) {
      sendFile(files[0],editor,welEditable);
    }
  });

  });
</script>
<script type="text/javascript">
  function sendFile(file, editor, welEditable) {
    data = new FormData();
    data.append("file", file);
    url = "http://localhost/spichlerz/uploads";
    $.ajax({
      data: data,
      type: "POST",
      url: url,
      cache: false,
      contentType: false,
      processData: false,
      success: function (url) {
        editor.insertImage(welEditable, url);
      }
    });
  }
</script>



<td><textarea class="summernote" rows="10" cols="100" name="tekst"></textarea></td>

当然，我有所有的js和CSS文件。我做错了什么？如果我点击图片上传并转到编辑器，则图片不在textarea中。

如果删除sendFile函数和onImageUpload：图像保存在base64上。

Answer 1

我测试了这段代码和Works

的Javascript

<script>
    $(document).ready(function() {
        $('#summernote').summernote({
            height: 200,
            onImageUpload: function(files, editor, welEditable) {
                sendFile(files[0], editor, welEditable);
            }
        });
        function sendFile(file, editor, welEditable) {
            data = new FormData();
            data.append("file", file);
            $.ajax({
                data: data,
                type: "POST",
                url: "Your URL POST (php)",
                cache: false,
                contentType: false,
                processData: false,
                success: function(url) {
                    editor.insertImage(welEditable, url);
                }
            });
        }
    });


</script>

PHP

if ($_FILES['file']['name']) {
            if (!$_FILES['file']['error']) {
                $name = md5(rand(100, 200));
                $ext = explode('.', $_FILES['file']['name']);
                $filename = $name . '.' . $ext[1];
                $destination = '/assets/images/' . $filename; //change this directory
                $location = $_FILES["file"]["tmp_name"];
                move_uploaded_file($location, $destination);
                echo 'http://test.yourdomain.al/images/' . $filename;//change this URL
            }
            else
            {
              echo  $message = 'Ooops!  Your upload triggered the following error:  '.$_FILES['file']['error'];
            }
        }

Summernote v0.8.1的图像上传

用于大图像

$('#summernote').summernote({
    height: ($(window).height() - 300),
    callbacks: {
        onImageUpload: function(image) {
            uploadImage(image[0]);
        }
    }
});

function uploadImage(image) {
    var data = new FormData();
    data.append("image", image);
    $.ajax({
        url: 'Your url to deal with your image',
        cache: false,
        contentType: false,
        processData: false,
        data: data,
        type: "post",
        success: function(url) {
            var image = $('<img>').attr('src', 'http://' + url);
            $('#summernote').summernote("insertNode", image[0]);
        },
        error: function(data) {
            console.log(data);
        }
    });
}

Answer 3

带有进度条的上传图片

我想我会扩展user3451783的答案并提供一个HTML5进度条。我发现在不知道是否发生任何事情的情况下上传照片非常烦人。

<强> HTML

<progress></progress>

<div id="summernote"></div>

<强> JS

// initialise editor

$('#summernote').summernote({
        onImageUpload: function(files, editor, welEditable) {
            sendFile(files[0], editor, welEditable);
        }
});

// send the file

function sendFile(file, editor, welEditable) {
        data = new FormData();
        data.append("file", file);
        $.ajax({
            data: data,
            type: 'POST',
            xhr: function() {
                var myXhr = $.ajaxSettings.xhr();
                if (myXhr.upload) myXhr.upload.addEventListener('progress',progressHandlingFunction, false);
                return myXhr;
            },
            url: root + '/assets/scripts/php/app/uploadEditorImages.php',
            cache: false,
            contentType: false,
            processData: false,
            success: function(url) {
                editor.insertImage(welEditable, url);
            }
        });
}

// update progress bar

function progressHandlingFunction(e){
    if(e.lengthComputable){
        $('progress').attr({value:e.loaded, max:e.total});
        // reset progress on complete
        if (e.loaded == e.total) {
            $('progress').attr('value','0.0');
        }
    }
}

Answer 4

此代码与新版本（v0.8.12）（2019-05-21）一起很好地工作

$('#summernote').summernote({
        callbacks: {
            onImageUpload: function(files) {
                for(let i=0; i < files.length; i++) {
                    $.upload(files[i]);
                }
            }
        },
        height: 500,
    });

    $.upload = function (file) {
        let out = new FormData();
        out.append('file', file, file.name);

        $.ajax({
            method: 'POST',
            url: 'upload.php',
            contentType: false,
            cache: false,
            processData: false,
            data: out,
            success: function (img) {
                $('#summernote').summernote('insertImage', img);
            },
            error: function (jqXHR, textStatus, errorThrown) {
                console.error(textStatus + " " + errorThrown);
            }
        });
    };

PHP代码（upload.php）

if ($_FILES['file']['name']) {
 if (!$_FILES['file']['error']) {
    $name = md5(rand(100, 200));
    $ext = explode('.', $_FILES['file']['name']);
    $filename = $name . '.' . $ext[1];
    $destination = 'images/' . $filename; //change this directory
    $location = $_FILES["file"]["tmp_name"];
    move_uploaded_file($location, $destination);
    echo 'images/' . $filename;//change this URL
 }
 else
 {
  echo  $message = 'Ooops!  Your upload triggered the following error:  '.$_FILES['file']['error'];
 }
}

Answer 5

Summernote默认将您上传的图像转换为一些无意义的字符串，您可以处理该字符串，或者正如其他人提到的那样，您可以使用onImageUpload回调来上传图像。您可以看一下这个gist，我对其进行了一些修改以适应laravel csrf token here。但这对我没有用，我没有时间找出原因！相反，我通过基于server-side solution的this blog post解决了它。它获取summernote的输出，然后将上传图像并更新最终的markdown HTML。

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;

Route::get('/your-route-to-editor', function () {
    return view('your-view');
});

Route::post('/your-route-to-processor', function (Request $request) {

       $this->validate($request, [
           'editordata' => 'required',
       ]);

       $data = $request->input('editordata');

       //loading the html data from the summernote editor and select the img tags from it
       $dom = new \DomDocument();
       $dom->loadHtml($data, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);    
       $images = $dom->getElementsByTagName('img');

       foreach($images as $k => $img){
           //for now src attribute contains image encrypted data in a nonsence string
           $data = $img->getAttribute('src');
           //getting the original file name that is in data-filename attribute of img
           $file_name = $img->getAttribute('data-filename');
           //extracting the original file name and extension
           $arr = explode('.', $file_name);
           $upload_base_directory = 'public/';

           $original_file_name='time()'.$k;
           $original_file_extension='png';

           if (sizeof($arr) ==  2) {
                $original_file_name = $arr[0];
                $original_file_extension = $arr[1];
           }
           else
           {
                //the file name contains extra . in itself
                $original_file_name = implode("_",array_slice($arr,0,sizeof($arr)-1));
                $original_file_extension = $arr[sizeof($arr)-1];
           }

           list($type, $data) = explode(';', $data);
           list(, $data)      = explode(',', $data);

           $data = base64_decode($data);

           $path = $upload_base_directory.$original_file_name.'.'.$original_file_extension;

           //uploading the image to an actual file on the server and get the url to it to update the src attribute of images
           Storage::put($path, $data);

           $img->removeAttribute('src');       
           //you can remove the data-filename attribute here too if you want.
           $img->setAttribute('src', Storage::url($path));
           // data base stuff here :
           //saving the attachments path in an array
       }

       //updating the summernote WYSIWYG markdown output.
       $data = $dom->saveHTML();

       // data base stuff here :
       // save the post along with it attachments array
       return view('your-preview-page')->with(['data'=>$data]);

});
