Question

automatic_uploads

Enable or disable automatic upload of images represented by data URLs or blob URIs. Such images get generated, for example, as a result of image manipulation through Image Tools plugin, or after image is drag-n-dropped onto the editor from the desktop.

Warning: Note that, this option will do nothing if images_upload_url is not specified.

Type: Boolean

Default Value: true

Possible Values: true, false

Example

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  images_upload_url: 'postAcceptor.php',
  automatic_uploads: false
});

file_picker_callback

This hook can be used to add custom file picker to those dialogs that have it. Internally we support this in Image, Media and Link dialogs. This replaces the file_browser_callback (removed in version 5.0) option. The new file_picker_callback provides a way to update values of other fields in the dialog.

Once you define file_picker_callback, small browse button will appear along the fields of supported file types (see file_picker_types). When user clicks the button, TinyMCE will automatically call the callback with three arguments:

• callback - a callback to call, once you have hold of the file; it expects new value for the field as the first argument and optionally meta information for other fields in the dialog as the second one
• value - current value of the affected field
• meta - object containing values of other fields in the specified dialog (notice that meta.filetype contains the type of the field)

It should be noted, that we only provide a hook. It is up to you to implement specific functionality.

Type: JavaScript Function

The following example demonstrates how you can use file_picker_callback API, but doesn’t pick any real files. Check Basic Local File Picker demo for a more functional example.

Example

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  file_picker_callback: function(callback, value, meta) {
    // Provide file and text for the link dialog
    if (meta.filetype == 'file') {
      callback('mypage.html', {text: 'My text'});
    }

    // Provide image and alt text for the image dialog
    if (meta.filetype == 'image') {
      callback('myimage.jpg', {alt: 'My alt text'});
    }

    // Provide alternative source and posted for the media dialog
    if (meta.filetype == 'media') {
      callback('movie.mp4', {source2: 'alt.ogg', poster: 'image.jpg'});
    }
  }
});

file_picker_types

This option enables you to specify what types of file pickers you need by a space or comma separated list of type names. There are currently three valid types: file, image and media.

Type: String

Possible Values: file, image, media

Example

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  file_picker_types: 'file image media'
});

images_dataimg_filter

The images_dataimg_filter option lets you specify a filter predicate function for disabling the logic that converts base64 images into blobs while within the editor. This feature is generally used for very advanced integrations where you handle all base64/blob images with custom logic.

Type: JavaScript Function

Example

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  images_dataimg_filter: function(img) {
    return img.hasAttribute('internal-blob');
  }
});

images_reuse_filename

By default TinyMCE will generate unique filename for each uploaded file (for details refer to Upload Images). Sometimes this might have undesirable side-effects. For example, ,when automatic_uploads is enabled, every manipulation on the image done with Image Tools plugin, results in file upload and each time under a different filename, despite the fact that the image stays the same.

Setting images_reuse_filename to true tells TinyMCE to use the actual filename of the image, instead of generating a new one each time. Take into account that src attribute of the corresponding <img> tag gets replaced with whatever filename you send back from the server (see images_upload_url). It can be the same filename or something else, but the next time that filename is used for the upload.

Type: Boolean

Default Value: false

Possible Values: true, false

Example

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  automatic_uploads: true,
  images_upload_url: 'postAcceptor.php',
  images_reuse_filename: true
});

images_upload_base_path

This option lets you specify a basepath to prepend to URLs returned from the configured images_upload_url page.

Type: String

Example

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  images_upload_base_path: '/some/basepath'
});

images_upload_credentials

The images_upload_credentials option lets you specify if calls to the configured images_upload_url should pass along credentials like cookies etc. cross domain.

Type: Boolean

Default Value: false

Possible Values: true, false

Example

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  images_upload_credentials: true
});

images_upload_handler

The images_upload_handler option allows you to specify a function that is used to replace TinyMCE’s default JavaScript upload handler function with custom logic.

The upload handler function takes three arguments: blobInfo, a success callback, and a failure callback. When this option is not set, TinyMCE utilizes an XMLHttpRequest to upload images one at a time to the server and calls the success callback with the location of the remote image.

Note: Please note that when using this option, no other image uploader options are necessary. Additionally, if you would like TinyMCE to replace the <image> tag’s src attribute with the remote location, please use the success callback defined in the images_upload_handler function with the returned JSON object’s location property.

Type: JavaScript Function

Example

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  images_upload_handler: function (blobInfo, success, failure) {
    var xhr, formData;

    xhr = new XMLHttpRequest();
    xhr.withCredentials = false;
    xhr.open('POST', 'postAcceptor.php');

    xhr.onload = function() {
      var json;

      if (xhr.status != 200) {
        failure('HTTP Error: ' + xhr.status);
        return;
      }

      json = JSON.parse(xhr.responseText);

      if (!json || typeof json.location != 'string') {
        failure('Invalid JSON: ' + xhr.responseText);
        return;
      }

      success(json.location);
    };

    formData = new FormData();
    formData.append('file', blobInfo.blob(), blobInfo.filename());

    xhr.send(formData);
  }
});

images_upload_url

This option lets you specify a URL for the server-side upload handler. Upload will get triggered whenever you call editor.uploadImages() or - automatically, if automatic_uploads option is enabled. Upload handler should return a new location for the uploaded file in the following format:

{ "location": "folder/sub-folder/new-location.png" }

Be sure to checkout a demo implementation of the server-side upload handler here (written in PHP).

Type: String

Example

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  images_upload_url: 'postAcceptor.php'
});
