Is there any way I can make more than one default thumbnail in blogger? I would like to chose maybe three images to show at random when there is no post image.
Thanks!
you can use Math.random() with an array, for example
let thumbnails = ["thumb-1.png","thumb-2.png","thumb-3.png"];
// inside loop or whatever
if(/*check if post has thumbnail*/){
// use post thumbnail
// ...
} else { // else if no thumbnail use fallback
let noThumb = thumbnails[Math.floor(Math.random()*thumbnails.length)]
console.log(noThumb) // random thumbnail
}

I am trying to use QuillJS to let the user write a rich text, and then store it as JSON to display later on. There are 2 of these rich text areas in a single form, and may include images. QuillJS encodes images as base64 strings, and my POST request results in 413 by Express.
I have tried to change the limits by adding express json parameters, even trying extreme numbers.
// app.js
//----------------------------------------------------
// Middlewares
//----------------------------------------------------
app.use(express.json({limit: '2000mb'}));
app.use(express.urlencoded({extended: true, limit:'2000mb'}));
Even this did not help and I think it is not logical to let these parameters with such values.
I tried with json and urlencoded enctypes. When I tried to post with multipart/form, req.body was empty.
// My html page (pugJS)
form(enctype='application/x-www-form-urlencoded', action='/editor/page',
method='POST', onsubmit='return addContent()')
.form-control
label Content-1
div#toolbar
div#editor
input#content(name='content', type='text', hidden)
addContent() function that runs before form submit simply changes input#content's value with JSON.stringify(#editor.getContents())
I want to be able to store two quill content in a single database row, to display later.
A better approach to this would be to overwrite the image upload function and then save the image in Amazon S3 or some cloud server. Then you paste it inside the editor as <img src="http://uploaded-image-url"> This would solve your problem of maximum memory issue.
I fixed my problem few hours before #argo mentioned and I did it that way. So I wanted to post little bit of detail to the solution. I have been also guided by a github issue but can't seem to find the link again, in case I find it I will edit the post and add it.
// Quill - EN content
var quillEn = new Quill('#editor-en', {
modules: {
toolbar: toolbarOptions
},
theme: 'snow'
});
// set custom image handler
quillEn.getModule('toolbar').addHandler('image', () => {
selectLocalImage(quillEn);
});
// create fake input to upload image to quill
function selectLocalImage(editor) {
const input = document.createElement('input');
input.setAttribute('type', 'file');
input.setAttribute('accept', 'image/png, image/jpeg')
input.click();
// Listen upload local image and save to server
input.onchange = () => {
const file = input.files[0];
saveImageToServer(editor, file);
};
}
// upload image to server
function saveImageToServer(editor, file) {
const fd = new FormData();
fd.append('image', file);
const xhr = new XMLHttpRequest();
xhr.open('POST', '/api/page/upload_image', true);
xhr.onload = () => {
if (xhr.status === 200) {
// this is callback data: url
const url = JSON.parse(xhr.responseText).data;
insertToEditor(editor, url);
}
};
xhr.send(fd);
}
// manipulate quill to replace b64 image with uploaded image
function insertToEditor(editor, url) {
// push image url to rich editor.
const range = editor.getSelection();
editor.insertEmbed(range.index, 'image', url.toString());
}
In the backend where you POST image, you must return json as { data: FullUrlToImg } with 200 response, if you want to change your status to 201 or something else, don't forget to update it in saveImageToServer function.
So to summarize, you set custom image handler for your quill editor, you post the image to server as soon as user chooses to insert, then you replace the URL with your uploaded image in the editor.
Thanks.
I want to create xul based frame in one of my firefox extension. The frame should look like https://developer.mozilla.org/en-US/Add-ons/SDK/Low-Level_APIs/ui_frame
or
how to use below node js code in xul:
var { Frame } = require("sdk/ui/frame");
var frame = new Frame({
url: "./city-info.html"
});
In node.js, its working fine, but I dont know how to create the same thing with xul. Anybody can help?
thanks in advance.
You have provided very little detail as to what you desire. If all that you desire is to create an <iframe> in which you can load HTML content, then something along the lines of the following will do so:
//The URL of the HTML you desire to load.
let chromeUrl = '[Some URL here]';
//Whatever element you want the iframe placed under.
let parentEl = document.getElementById('foo');
//* Overlay and bootstrap (from almost any context/scope):
Components.utils.import('resource://gre/modules/Services.jsm');//Services
let activeWindow = Services.wm.getMostRecentWindow('navigator:browser');
//*/
let mainDocument = activeWindow.document;
//Create the <iframe> use
//mainDocument for the XUL namespace.
let iframeEl;
if(options.useBrowser){
iframeEl = mainDocument.createElement('browser');
} else {
iframeEl = mainDocument.createElement('iframe');
}
iframeEl.id = id;
iframeEl.setAttribute('src',chromeUrl);
iframeEl.setAttribute("tooltip", "aHTMLTooltip");
iframeEl.setAttribute("autocompleteenabled", true);
iframeEl.setAttribute("autocompletepopup", "PopupAutoComplete");
iframeEl.setAttribute("disablehistory",true);
iframeEl.setAttribute('type', 'content');
parentEl.appendChild(iframeEl);
The above code was taken from my answer to Firefox SDK Add-on with a sidebar on both the right and left at the same time, which creates sidebars. One option of how those sidebars are created is to have them contain an <iframe>.
Finally I got the answer:
let chromeUrl = 'YOUR HTML PAGE URL';
Components.utils.import('resource://gre/modules/Services.jsm');//Services
let activeWindow = Services.wm.getMostRecentWindow('navigator:browser');
//*/
let mainDocument = activeWindow.document;
let iframeEl;
iframeEl = mainDocument.createElement('iframe');
iframeEl.id = "d";
iframeEl.setAttribute('src',chromeUrl);
iframeEl.setAttribute("tooltip", "aHTMLTooltip");
iframeEl.setAttribute("autocompleteenabled", true);
iframeEl.setAttribute("autocompletepopup", "PopupAutoComplete");
iframeEl.setAttribute("disablehistory",true);
iframeEl.setAttribute('type', 'content');
iframeEl.setAttribute('height', '32px');
window.document.documentElement.appendChild(iframeEl);
On our site, other admins add images via the "Resources" tab of the main page. These images are displayed as Banners in a Slider on the main page. However, now they want the ability to add links to specific images.
My first thought on this (after receiving some help on making a loop for images to be added to the page) was to perhaps let them be able to add the link to either the "Title" or "Caption" spot I saw there. And later, on the slider "create" function, pull the said data from the image and make <a> wrap around the image before the slider finished building. I've already tested the slider plugin with this functionality, and that would work fine, however, I can't seem to pull anything from the "Title" or "Caption" and add it to the image in any way.
My other thought would be, is there a way to extend the back end to give them an actualy spot to paste links on images so that I may pull that and wrap the image via the typoscript, or can i pull from caption and wrap image in <a> "if" the link is available.
In other words, does typoscript have a type of "if" statement? What I ahve so far, thanks to maholtz is as follows:
#BANNER IMAGES LOOP BEGIN
page.10.marks.topimage = TEXT
page.10.marks.topimage {
# retrieve data
data = levelmedia: -1, "slide"
override.field = media
# we have some filenames in a list, let us split the list
# and create images one by one
# if there are five images selected, the CARRAY "1" will be executed
# five times where current is loaded with only one filename
split {
# the images are separated via ","
token = ,
# you can do funny stuff with options split, f.e. if you want to give first
# and last image a different class... but thats another topic;)
# we just say, render every splitted object via CARRAY "1"
cObjNum = 1
1 {
# just render the single image,
# now there should be one filename in current only
10 = IMAGE
10 {
file.import.wrap = fileadmin/user_upload/|
file.import.current = 1
border = 0
file.height = 670
file.width = 1800
altText = Banner
titleText = Banner
# attempt to add link to image if available
caption.1.typolink.parameter.field = image_link
caption.1.typolink.parameter.listNum.stdWrap.data = register:IMAGE_NUM_CURRENT
}
}
}
wrap = <div id="slides">|</div>
}
#BANNER IMAGES LOOP END
I was thinking perhaps I could do something like:
10 {
file.import.wrap = fileadmin/user_upload/|
file.import.current = 1
border = 0
file.height = 670
file.width = 1800
altText = Banner
titleText = Banner
# attempt to add link to image if available
caption.1.typolink.parameter.field = ???
caption.1.typolink.parameter.listNum.stdWrap.data = register:IMAGE_NUM_CURRENT
}
But as you can see, I'm stumped on how that might even work right. Can anyone help point me the right way.
As before mentioned, perhaps I could do ONE of two things:
Pull link from "Title" or "Caption" and add it to the IMAGE Date on output so that I can use that client side to wrap the image in appropriate a tag, |OR|
Pull link from there and use typoscript to wrap the image in a tags
When accessing the ressources via levelmedia = slide you're not directly accessing the FAL table. Therefore you have to load it again to access the fields you want. We solved exactly the problem you have with the following code. Insert it inside your 1 after 10 = IMAGE.
typolink{
parameter{
cObject = RECORDS
cObject{
source.current = 1
tables = sys_file_reference
conf.sys_file_reference = TEXT
conf.sys_file_reference.field = #title or description
}
}
}
I've been playing around with the FB SDK and some examples that exist for displaying FB photo albums, but the examples are much more complex than what I want to do. All I want to do is set the album id for a single album and pull in the contents. That's it, I can style everything after that, I just need to be able to view the contents of one album and pull in the caption for each photo.
I'm trying to create a WordPress album that does this; I can easily create the base of the widget, but I'm lost when it comes to API's.
Are there any examples out there that I've overlooked?
Does anyone know how to accomplish this?
hopefully this gives you a hint ;)
<?
if (empty($_GET['album'])) {
//get all albums of page
$graph_url = "https://graph.facebook.com/PressPlayPrague/albums? fields=id,link,name,cover_photo&limit=500";
$albums = json_decode(file_get_contents($graph_url));
$counted = sizeof ($albums->data); // get the number of albums for later use
//output all albums of given page
for($c=0; $c<$counted; $c++){
echo ("<div class='wrapper' <a href='?album=".$albums->data[$c]->id."'><div class='stack'><div style='width:180px; height:120px; display:inline-block; background-image:url(https://graph.facebook.com/".$albums->data[$c]->id."/picture?width=300&height=200); background-repeat:no-repeat;'> </div></div><div class='caption'>".$albums->data[$c]->name."</div></a></div>");
};
}else{
//get the album pictures replace the $_GET[album] with specific ID and remove the if clause to get only one album
$pic_url = "https://graph.facebook.com/".$_GET[album]."/photos?fields=picture&limit=500";
$pictures = json_decode(file_get_contents($pic_url));
$countpic= sizeof ($pictures->data); // get the number of pics for later use
for($p=0; $p<$countpic; $p++){
echo ("<img style='width:250px; max-height:167px;' src='https://graph.facebook.com/".$pictures->data[$p]->id."/picture' alt='".$pictures->data[$p]->id."'>");
};
}
?>
Is there anyway to get the full-size profile picture using any facebook api?
http://graph.facebook.com/{ID}/picture?type=large is way to small.
Thanks :)
Set either the width or height to some arbitrarily large number:
https://graph.facebook.com/username_or_id/picture?width=9999
If the width and height are the same number, the photo is cropped to a square.
I think I use the simplest method to get the full profile picture. You can get full profile picture or you can set the profile picture dimension yourself:
$facebook->api(me?fields=picture.width(800).height(800))
You can set width and height as per your need. Though Facebook doesn't return the exact size asked for, It returns the closest dimension picture available with them.
found a way:
$albums = $facebook->api('/' . $user_id . '/albums');
foreach($albums['data'] as $album){
if ($album['name'] == "Profile Pictures"){
$photos = $facebook->api('/' . $album['id'] . '/photos');
$profile_pic = $photos['data'][0]['source'];
break;
}
}
As noted above, it appears that the cover photo of the profile album is a hi-res profile picture. I would check for the album type of "profile" rather than the name though, as the name may not be consistent across different languages, but the type should be.
To reduce the number of requests / parsing, you can use this fql:
"select cover_object_id from album where type='profile' and owner = user_id"
And then you can construct the image url with:
"https://graph.facebook.com/" + cover_object_id + "/picture&type=normal&access_token=" + access_token
Looks like there is no "large" type for this image, but the "normal" one is still quite large.
As noted above, this photo may be less accessible than the public profile picture. You need the user_photos or friend_photos permission to access it.
With Javascript you can get full size profile images like this
pass your accessToken to the getface() function from your FB.init call
function getface(accessToken){
FB.api('/me/friends', function (response) {
for (id in response.data) {
var homie=response.data[id].id
FB.api(homie+'/albums?access_token='+accessToken, function (aresponse) {
for (album in aresponse.data) {
if (aresponse.data[album].name == "Profile Pictures") {
FB.api(aresponse.data[album].id + "/photos", function(aresponse) {
console.log(aresponse.data[0].images[0].source);
});
}
}
});
}
});
}
For Angular:
getUserPicture(userId) {
FB.api('/' + userId, {fields: 'picture.width(800).height(800)'}, function(response) {
console.log('getUserPicture',response);
});
}
Profile pictures are scaled down to 125x125 on the facebook sever when they're uploaded, so as far as I know you can't get pictures bigger than that. How big is the picture you're getting?
