Login Opening Page

heper

mobile devices generally have a captive-portal detection & automatically open the portal page.
this automatic browser is generally crap. it doesn't always play nice with javascript & css.

try manually opening the page on the mobile device with the chrome or firefox app ... it will probably be fine

best bet is to remove all unnecessary stuff from the portal page, try to use plain html5

@heper

we don't want html to be plain plain plain
spelling limitations, letters, numbers etc.
Therefore css and js codes are required

@ahmetakkaya

then you should write a letter to the retards at google & apple to fix their crap

What kind of problem can happen when .*css, *.js files come to login phase?

css files : dono.
But the stripped down, OS controlled mini browser, used to login into captive portholes doesn't do "cookies" "cache" and all kind of script things like javascript. Your js files will be ignored.

How to make a welcome page without css and js
need number letter restrictions on page
You should also check the number account registration

Use the build in page as an example.

@ahmetakkaya said in Login Opening Page:

That's self imposed.
Just have the user press the Ok button.
Write some PHP or whatever 'web server' side code to do the checking work for you. If that fails, the login error page will show up.

" number account registration"

so when the login goes wrong, the login error page is displayed, which is / could be the same page as the login page, with extra an $error message shown (see build in login error page as an examole). Use that one to show example how the user could login.
You could even link a clickable URL that points to a PDF with full instructions on the login page.

Respect the golden rule : keep it simple.
Because, as said before, the "browsers" that hit bthe captive portal login page are not always the fully equipped FF/Chrome/Edge browsers.
When you write your own captive portal login page, you should have some high and Chinees phones (the expensive and the low bud ones), some American phones (those are only expensive), and some off the shelves classic Apple and Windows PC at hand to test using all ( !! ) available browsers. If some device using some browser fails, you remove that 'gadget' that brook on your login page. You wind up having a simple page.
Nice advantage : easy to maintain.
Remember : that page is to login, your not advertising there, or selling something on that page (are you ??).

Won't it be a visual theme

keeping it simple is a bad restriction

@ahmetakkaya You can also perform this debugging on mobile devices.

If you are having issues on some mobile phone, then you need to debug your CSS / JS directly on the mobile phone

Please see https://medium.com/samsung-internet-dev/secret-devtools-recipe-for-mobile-web-developers-3b8a75bfee4b for how to so that

I'm using style sheets for my captive prtal login page, as shown above. CSS files are just special html files.
What (might) pose problems are the script files like the .js files.

@gertjan

I imported css and js files into html
no result welcome screen
no solution

I left 1 css and 1 js out
result file does not come first welcome sentence

What do you mean ?

The build in default login page works ?

Your captive portal login page looks like this :

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> 
<html lang="en-EN">

	</head>
	<body> 
		<div style="text-align:center; margin:0 auto;"> 
			<form method="post" action="$PORTAL_ACTION$">

<?php

	if(isset($config['voucher'][$cpzone]['enable'])) {
?>
	<p><input name="auth_voucher" type="text" /></p>
<?php
	}
?>
			</form> 
		</div> 
	</body>
</html>

edit : if the css contains error, then yeah, the browser might complain or bail out.
It's debugging time, as explained above.
