upload_Images | 多图上传-自己对插件做过修改 -

i have 3 functions :

I'm learning Angular by building a small Real Estate agency as a pet project. I have modal with a form in which user can add new Estate - basic data and pictures. Firstly i want to save it to the Cloudinary and then save urls in to Firebase.

I cannot make it work in order, instead Firebase is called first with empty urls array. I found there is function finalize() in rxjs but it doesn't work either.

CloudinaryService :

I am creating a Dash app that allows the user to either enter URLS to be screenshot and then analyzed or the user can upload their own images. I am trying to get the main app.py file right so the inputs can be sent to one of three different functions (one that only takes screenshots of the websites they listed, one that uses robots to search for similar websites and then takes screenshots of those to be analyzed, or just having the user upload their own images to be analyzed). Note that once they hit the "Submit" button, that the relevant inputs (the email, company name, and URL/images) will be passed off to an rq job. I understand how to do this part, so for the example, we can just print out the relevant inputs in the web app just to confirm that we have the right inputs.

The idea for the UI is that it would first have a section to put your email (and other info), and then start with radio buttons for each screenshot option. Then depending on the user's preference of the inputs they want to provide, they would either be shown a place for them to enter the different URLs or a place to upload their images (See image here).

It seems that pattern-matching would be useful for them to add more URLs, but I can't quite figure out how to allow different types of inputs using it. Here's what I have so far:

Suppose, we want to check the width of an image before uploading it. Here is the fiddle. In the end we need to wait for the end of all the asynchronous operations. I tried to use Promises for this purpose. But, unfortunately, good_images are empty inside alert. Seems, that I'm missing something simple.

I tried Promise.all, but it also doesn't work. Fiddle.

I use array to add or remove mutli files to upload , the proplem that when i want to upload files by ajax and formdata it's not work in my php file and i can't catch the uploaded file here is my upload function.

I am stuck with the data structure of this function I designed. The role of this function should be to pick index1 file from each directory and upload it and then go to the second index for each directory. The current design accomplishes the task but it uploads all the files for the first directory and then moves to the second directory and so on.

I'm developing a program that uploads the user Logo, or image. To do so, I first create a signature on the server-side and then upload the image from the client to cloudinary, with that signature.

Problem is that I always get the following error: `Invalid Signature "b4000077c554448649396c31750e27141820693c". String to sign - 'source=uw&timestamp=1598531294&upload_preset=signed-preset'.`` (with a different signature and timestamp ofc.)

I followed the guide on their docs: https://cloudinary.com/documentation/upload_images#generating_authentication_signatures But with no help,

Here's the client-side code:

I get following error:

There is no extension able to load the configuration for "upload_images" (in "/var/www/vhosts/diabetigraph-dev/vendor/verzeilberg/upload-images/src/Resources/services.yaml"). Looked for namespace "upload_images", found "none"

This are my files:

services.yaml

I have this code on a file called images.js to search for specific images and download it. The same is a function exported for the main code:
