夏日笔记图片上传

Question

我对编辑器Summernote有问题。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？如果我单击图像上传并转到编辑器，则图像不在文本区域中。

如果我删除发送文件函数和图像上传：图像保存在base64上。

Answer 1

我测试了这段代码并工作

爪哇语

<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));
    $ext = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION);
    $filename = $name.
    '.'.$ext;
    $destination = '/assets/images/'.$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'];
  }
}

更新：

在 0.7.0 之后，onImageUpload应该在callbacks选项内，如@tugberk所述

$('#summernote').summernote({
    height: 200,
    callbacks: {
        onImageUpload: function(files, editor, welEditable) {
            sendFile(files[0], editor, welEditable);
        }
    }
});

Summernote v0.8.1 的图片上传

对于大图像

$('#summernote').summernote({
    height: ($(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

使用进度条上传图片

以为我会扩展user3451783的答案，并提供一个HTML5进度条。我发现上传照片而不知道是否发生了什么事非常烦人。

.HTML

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

.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

此代码适用于新版本 （v0.8.12） （2019-05-21）

$('#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 （上传.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

默认情况下，

Summernote 会将您上传的图像转换为 base64 编码字符串，您可以处理此字符串，或者正如其他研究员提到的，您可以使用onImageUpload回调上传图像。你可以看看这个要点，我在这里修改了一点以适应拉拉维尔csrf token。但这对我不起作用，我没有时间找出原因！相反，我通过基于这篇博文的服务器端解决方案解决了它。它获取夏季笔记的输出，然后上传图像并更新最终的降价 HTML。

use IlluminateHttpRequest;
use IlluminateSupportFacadesStorage;
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]);
});

Answer 6

我在这里尝试了几乎所有的答案，但没有一个在 v0.8.18 中对我有用。

我找到了一个简单的解决方案，有人可能需要它。

在这里：

打开您的 js summernote/summernote-lite.js并找到onImageUpload: null,。

替换为 ：

onImageUpload: function(files) {
var $editor = $(this);
var data = new FormData();
 data.append('file', files[0]);
 $.ajax({
     url: 'editor-upload.php',
     method: 'POST',
     data: data,
     processData: false,
     contentType: false,
     success: function(response) {
       $editor.summernote('insertImage', response);
     }
 });
},

简单的php示例： editor-upload.php

if(empty($_FILES['file']))
{
    echo "Insert image";
}
$errorImgFile = "img/img_upload_error.jpg";
$destinationFilePath = 'img-uploads/'.$_FILES['file']['name'];
if(!move_uploaded_file($_FILES['file']['tmp_name'], $destinationFilePath)){
    echo $errorImgFile;
}
else{
    echo $destinationFilePath;
}

清除浏览数据并刷新页面，就是这样，它就像一个魅力。
