WordPress media library with metadata limit

I want to create a media library window. attachment should filter with mime types and metadata.
the mime-type filter is done. How can I build a metadata filter just for this?
function upload_image_tinymce(e) {
e.preventDefault();
var $input_field = $('.mce-my_input_image');
var custom_uploader = wp.media.frames.file_frame = wp.media({
title: 'Add Video',
button: {
text: 'Add Video'
},
library: {
type: [
'video/MP4',
'video/quicktime',
'video/x-m4v',
],
},
multiple: false
});
custom_uploader.on('select', function() {
var attachment = custom_uploader.state().get('selection').first().toJSON();
$input_field.val(attachment.id);
});
custom_uploader.open();
}

I cant help you with the whole filter code (not enoth knowlage ...)
But you can use the hook wp_get_attachment_metadata('attachment id') to get an array with the whole metadata of the attachment.
$meta = wp_get_attachment_metadata(126);
Will produce an array with the metadata from the attachment 126.
$cam = $meta[camera]
$cam will then hold the camera string from the metadata ...
Not much but maybe it will lead you a little bit in the right direction.

Node Webkit -Save As dialog with multiple option on "Save as Type" field

Using Node Webkit, is it possible to create save as with multiple option of the file format?
Desired result is something like this :
With native NW at most I can only display two options. The first option is the pattern written in the 'accept' attribute, and an auto generated "All files (.)" Option.
What I need is more than two options in the Save As Type field.
Is there a way to achieve this?

What you will have to do is to give different 'description' and 'accept' of each option you want to show.
This way the saveAs dialog will show you the options and you can save your file with that source.
You can use showSaveFilePicker.
async function saveFile () {
const result = await window.showSaveFilePicker({
types: [
{
description: 'Web Page, complete(*.htm;*.html)',
accept: {
'file/*':['.html']
}
},
{
description: 'Web Page, complete(*.htm;*.html)',
accept: {
'file/*': ['.html'],
}
},
{
description: 'Web Page, HTML only(*.htm,*.html)',
accept: {
'file/*': ['.html'],
}
},
{
description: 'Text File (*.text,*.text) HTML only(*.htm,*.html)',
accept: {
'file/*': ['.txt'],
}
}
]
});
return result;
}

Second File Upload fails in ExtJS 6, works in ExtJS 4

Very low-level file upload:
dockedItems: [{
xtype: 'toolbar',
dock: 'top',
items: [{
xtype: 'form',
items: [{
xtype: 'filefield',
fieldLabel: 'Select file',
listeners: {
change: {
fn: me.onFilefieldChange,
scope: me
}
}
}]
},{
...
onFilefieldChange: function(filefield, value, eOpts) {
var form = filefield.up('form').getForm();
form.submit({
url: APIURI+'FileUpload',
headers: {'Accept':'application/json','Content-Type':'application/json'},
waitMsg: 'Uploading',
success: function(fp, o) {
var filedata = Ext.decode(o.response.responseText).data;
var rec = Ext.create("MyApp.model.FileModel",filedata);
Ext.getStore("FileStore").add(rec);
},
failure: function(fp, o) {
Ext.alert("ERROR", "File save failed"));
}
});
The first file upload works like a charm; the file is packed into the multipart/mime and submitted correctly.
The second file upload from the very same file upload field fails, because the file is not packed into the mime.
If I close the window and open it again, the file field is working again - for a single upload, that is.
The difference in DOM of the file input field tells us why the browser behaves like this. The following three attributes are magically missing from the <input type="file" field after the first file upload:
data-ref=​"fileInputEl"
name=​"filefield-1333-button"
data-componentid=​"filefield-1333-button"
Now, this does not happen if I use the file upload field in the sencha docs. It doesn't happen with my code in ExtJS 4.2.2. But it does happen with ExtJS 6.0.1.
You wouldn't know why, would you?

It is a bug in Sencha ExtJS 6 Framework. Everything works as expected if you provide a name property to the file upload field.
xtype: 'filefield',
fieldLabel: 'Select file',
name: 'RequiredSenchaBugWorkaround',
...

Adding a name doesn't always work. It still has issues in Ext 6.2. In addition to that you should do
FileInputField1.reset();
This makes sure that the field is reset and lets you upload the same file again.

CKEditor + CKFinder image uploads

I'm using CKEditor 4.5.2 with CKFinder 3.0.0 on PHP 5.6. Generally the integration works fine - when I click the CKEditor image button, I can click the "Browse server" button and CKFinder opens, I can select images, and also do uploads.
What doesn't work is the 'Upload' tab in the image2 dialogue. I always get an error saying "The requested resource type is not valid." when I click the "Send to server" button.
In my CKFinder config I have two resource types defined called Images and Library; these are essentialy the same except that Library is read-only - I only want to allow uploads to the Images type.
There are multiple ways of configuring the integration between CKEditor and CKFinder. I am using a custom JS config file for CKEditor and connecting ckFinder to it using the setupCKEditor method, as per the docs:
CKFinder.setupCKEditor(ckeditor_1, {
'height': '100%',
'jquery': '/js/jquery-1.11.3.min.js',
'skin': 'jquery-mobile',
'swatch': 'a',
'themeCSS': '/themes/mytheme.min.css',
'filebrowserBrowseUrl': '/ckfinder/ckfinder.html',
'filebrowserImageBrowseUrl': '/ckfinder/ckfinder.html?Type=Images',
'filebrowserImageUploadUrl': '/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Images'
}, "Images");
I've tried passing the same values to CKEditor in my CKEDITOR.replace call, and also set them on the config property in my external config file, yet nothing changes - I still get the same error.
How should I do this? Alternatively, since the CKFinder uploader works fine, how can I disable the upload tab in the image2 dialogue?
Update: here's my current code for creating CKEditor and CKFinder instances:
var ckeditor_1 = CKEDITOR.replace('html', {
"baseHref":"http://mysite.mac.local/",
"toolbarStartupExpanded":true,
"extraPlugins":"symbol",
"customConfig":"/js/ckconfig.js"
});
CKFinder.setupCKEditor( ckeditor_1, {
'height': '100%',
'jquery': '/js/jquery-1.11.3.min.js',
'skin': 'jquery-mobile',
'swatch': 'a',
'themeCSS': '/themes/mytheme.min.css'
}, { type: "Images" } );
And my CKEditor config file:
CKEDITOR.editorConfig = function (config) {
// Define changes to default configuration here. For example:
// config.language = 'fr';
// config.uiColor = '#AADC6E';
config.docType = '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">';
config.toolbarGroups = [
{name: 'document', groups: ['mode', 'document', 'doctools']},
{name: 'clipboard', groups: ['clipboard', 'undo']},
{name: 'editing', groups: ['find', 'selection', 'spellchecker']},
{name: 'links'},
{name: 'insert'},
{name: 'tools'},
{name: 'others'},
'/',
{name: 'basicstyles', groups: ['basicstyles', 'cleanup']},
{name: 'paragraph', groups: ['list', 'indent', 'blocks', 'align']},
{name: 'styles'},
{name: 'colors'},
{name: 'about'},
{name: 'symbol'}
];
config.removePlugins = 'templates,save,specialchar,image,flash,scayt,forms,wsc,print,iframe,pagebreak';
CKEDITOR.plugins.addExternal('symbol', '/ckeditorplugins/symbol/', 'plugin.js');
config.extraPlugins = 'symbol';
config.templates_replaceContent = false;
config.templates_files = [
'/ckeditorplugins/templates/templates.js'
];
config.allowedContent = true;
config.toolbarCanCollapse = true;
config.fullPage = true;
config.skin = 'bootstrapck';
config.height = 400;
config.uiColor = '#f9dda0';
config.autoParagraph = false;
config.enterMode = CKEDITOR.ENTER_BR;
CKEDITOR.on('instanceReady', function (ev) {
ev.editor.dataProcessor.writer.selfClosingEnd = '>';
});
};

It looks like you mixed options for CKEditor and CKFinder. The second argument of CKFinder.setupCKEditor() is CKFinder configuration, while all filebrowser* options that you used belong to CKEditor configuration. Please have a look at CKFinder.setupCKEditor() docs. The third argument allows you to define upload URL parameters, so here you can point uploads to Images.
Please try following snippet:
CKFinder.setupCKEditor(ckeditor_1, {
'height': '100%',
'jquery': '/js/jquery-1.11.3.min.js',
'skin': 'jquery-mobile',
'swatch': 'a',
'themeCSS': '/themes/mytheme.min.css'
}, {type: "Images"});
When using CKFinder.setupCKEditor() the upload path for CKEditor will be set automatically, so there should be no need to configure it explicitly.
If the above doesn't work for you, please provide also code that creates ckeditor_1.

ExtJS 4 - How to download a file using Ajax?

I have a form with various textfields and two buttons - Export to Excel and Export to CSV.
The user can provide the values to different fields in the form and click one of the buttons.
Expected behaviour is that an Ajax request should be fired carrying the values of fields as parameters and the chosen file (Excel/CSV as per the button click) should get downloaded (I am not submitting the form as there needs to be done some processing at the values before submit).
I have been using the following code in success function of Ajax request for the download:
result = Ext.decode(response.responseText);
try {
Ext.destroy(Ext.get('testIframe'));
}
catch(e) {}
Ext.core.DomHelper.append(document.body, {
tag: 'iframe',
id:'testIframe',
css: 'display:none;visibility:hidden;height:0px;',
src: result.filename,
frameBorder: 0,
width: 0,
height: 0
});
The above code has been working fine in the case when the file is created physically at the server. But in my current project, the file is not created at the server, rather the contents are just streamed to the browser with proper headers.
Thus, is there a way to download a file using Ajax when the file is not present at the server physically? Just to add that I have a long list of parameters which I need to send to the server and hence can not add them all to the src of iframe.
Could anyone guide at this?
Thanks for any help in advance.

You may use component like this:
Ext.define('CMS.view.FileDownload', {
extend: 'Ext.Component',
alias: 'widget.FileDownloader',
autoEl: {
tag: 'iframe',
cls: 'x-hidden',
src: Ext.SSL_SECURE_URL
},
stateful: false,
load: function(config){
var e = this.getEl();
e.dom.src = config.url +
(config.params ? '?' + Ext.urlEncode(config.params) : '');
e.dom.onload = function() {
if(e.dom.contentDocument.body.childNodes[0].wholeText == '404') {
Ext.Msg.show({
title: 'Attachment missing',
msg: 'The document you are after can not be found on the server.',
buttons: Ext.Msg.OK,
icon: Ext.MessageBox.ERROR
})
}
}
}
});
Put it somewhere in viewport, for example:
{
region: 'south',
html: 'South',
items: [
{
xtype: 'FileDownloader',
id: 'FileDownloader'
}
]
}
Do not forget to require it in your viewport class:
requires: [
'CMS.view.FileDownload'
]
Action handler may look like this:
var downloader = Ext.getCmp('FileDownloader')
downloader.load({
url: '/attachments/' + record.get('id') + '/' + record.get('file')
});
It's very important to have Content-Disposition header in response, otherwise nothing is downloaded.

This thing works for me.
