I currently have a timer set up on an “admin” page with JavaScript and I want to display that same live clock on the homepage of my website. How can I do this? It’s basically two input fields that display number values. One displays minutes and one displays seconds. The values are updated using buttons which are found on the admin page. What I’m trying to do is display the current time that the clock is showing on the admin page on a separate page. Is there a simple way to do this?
You could store the value of the timer server side and just query it each second to see at what time it currently is. You could also use socket.IO to have real time access to the server timer.
It's impossible. website is connectionless.
You can't push any event to other client page
without client behavior(like button click..)

How to let user upload image in one page, and then display it in another page? User can change the image and it'll be changed also in the other page. Also, I'm talking about using php / js / jquery / mysqli anything that's most efficient. (I'm just a beginner in this field so it'll be appreciated if you use some simple language :))
Edit: Yes I said that I'm a beginner, but that doesn't mean I don't know a thing about coding. Also, I saw a few solutions from youtube & other stackoverflows questions, but all of them is about either uploading and displaying in the same page or not being able to change the image.
Format the image into Base64 string
store it in local-storage
In another page get it from local-storage and assign to the id or class.
Suggesting the link that already have answered for
How to save an image to localStorage and display it on the next page?

Since a year and a half I am trying to figure out how some websites update their content in real time without AJAX method.
Please see this example website: https://pro.btcturk.com/en/basic/exchange/BTC_TRY
That website is changing many texts within content in different timing.
It means that when the server is updated with new values in the database then the website is listening to database changes and then reflecting/delivering inside content without ajax calls.
Can someone give an example how to achieve such functionality possibly using Javascript or PHP normal hand-code appreciated?
Thank you
You can see the process here:

So, as I was making my website, I started to have many pages. So, I wanna ask today, if ya'll know anyway way how I can make a change to a page of my website, and those changes be apply to my other pages automatically. For example, if I make a change to my nav bar of my website, I don't wanna have to go to every single page and and do it manually, I wanna know if there is a way how I can make a change to the nav bar in one of the web page, and get the other pages get the updates automatically. I would very much appreciates any advice, thank you.
You can just write your navbar code into a separate file and include it wherever you need navbar. This way if you change the main navbar.php file it will reflect in every other page that includes navbar.php

You can try to work with long polling or comet or web socket features for auto-updating your chat system, while you want to check the user, starts typing or no.

I'm using bootstrap in my web API page, and i'm planning to put 9 tabs in a page. Each tabs will have to load database values based on drop-down choice and the choice will be displayed in a table, then from the table they will make another choice and then that choice will be added with several other textbox inputs to be stored in the database.
So there will be a to-and-fro data retrieve and send process for each. Is it wise to do this? Does it affect performance? Or should i put those tabs in separate pages?
This is more of a UX/IA issue than a coding concern. I would envision using AJAX to load/refresh each tab's content, which could affect performance based on how much data is returned, how the data is displayed, etc.
I'm typically a proponent of the "less is more" mindset so 9 tabs may be a lot, but again this is up to your app's purpose and UX.
