Summernote image upload

问题

I have a problem with editor Summernote. I want to upload images into a catalog on the server. I have some script:

<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>

Of course, I have all js and CSS files. What I do wrong? If I click on image upload and go to the editor, the image is not in textarea.

If I delete sendFile function and onImageUpload: the image save on base64.

I tested this code and Works

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'];
            }
        }

Update:

After 0.7.0 onImageUpload should be inside callbacks option as mentioned by @tugberk

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

Image Upload for Summernote v0.8.1

for large images

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

function uploadImage(image) {
    var data = new FormData();

            $('#summernote').summernote("insertNode", image[0]);
        },
        error: function(data) {
            console.log(data);
        }
    });
}

UPLOAD IMAGES WITH PROGRESS BAR

Thought I'd extend upon user3451783's answer and provide one with an HTML5 progress bar. I found that it was very annoying uploading photos without knowing if anything was happening at all.

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');
        }
    }
}

This code worked well with new version (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 Code (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'];
 }
}

Summernote converts your uploaded images to some nonsense string by default, you can process this string or as other fellows mentioned you can upload images using onImageUpload callback. You can take a look at this gist which I modified a bit to adapt laravel csrf token here. But that did not work for me and I had no time to find out why! Instead, I solved it via a server-side solution based on this blog post. It gets the output of the summernote and then it will upload the images and updates the final 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]);

});
