Summernote图片上传

Question

我对编辑Summernote有一个问题。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进入编辑器，图片不在文本区。

如果我删除了sendFile函数和onImageUpload:图像保存在base64上。

Answer 1

我测试了这段代码，并运行正常

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));
    $ext = pathinfo($_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版本之后，onImageUpload应该在@tugberk提到的callbacks选项中

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

Summernote v0.8.1的图像上传

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);
        }
    });
}

带有进度条的上传图像

我想扩展一下用户3451783的回答，并提供一个HTML5进度条。我发现，在不知道发生了什么事情的情况下上传照片是非常恼人的。

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');
        }
    }
}
