Add a description attribute to the xml file to produce duplicate id and aria-describedby.

@Quy
As far as I know, the code produced here is a11y ok. I am not sure we need a description.
See code results for the admin Search field in articles manager.
Will look again tomorrow anyway.

The code is correct. Its the only field on the user registration page that doesn't have accessibility errors.

The strings should match the strings in the admin

@Quy
I guess I now understand what you meant,
By design, the intention is to never use both a description and rules for the password field.
We use the description in Installation and should use the tooltip in other cases.

@brianteeman
My intention was to modify the backend labels.
Integers may not be and obvious word for many except developers/math people (anyway nobody is going to use figures like 1.5...) but Digits is fine in every language.
Length is imprecise because it is a neutral term. We are speaking here of a number of Characters. So, let's call it that way.

Also, if you look at the strings errors, they do use Digits and Characters
JFIELD_PASSWORD_NOT_ENOUGH_INTEGERS_N="Password does not have enough digits. At least %s digits are required."
JFIELD_PASSWORD_TOO_SHORT_N="Password is too short. Passwords must have at least %s characters."
etc.

I have in information only the number of characters. Is it right ?

@Magnytu2 Yes, because you have not changed password rules so they contain more requirements than the length. You can do that in com_users options on tab "Password Options". Please do so and check the result. Thanks in advance.

Yes everything works, except with the @ which must not be a symbol ? But I am happy to discover this function which I did not know.

Please mark your test OK on issues.joomla.org

I have tested this item ✅ successfully on 03d1366

Test ok

Would this be better without having to add the rule attribute and tooltip and fix the duplication?

if (!empty($description))
{
	$requirements = [];

	if ($minLength)
	{
		$requirements[] = Text::sprintf('JFIELD_PASSWORD_RULES_CHARACTERS', $minLength);
	}

	if ($minIntegers)
	{
		$requirements[] = Text::sprintf('JFIELD_PASSWORD_RULES_DIGITS', $minIntegers);
	}

	if ($minSymbols)
	{
		$requirements[] = Text::sprintf('JFIELD_PASSWORD_RULES_SYMBOLS', $minSymbols);
	}

	if ($minUppercase)
	{
		$requirements[] = Text::sprintf('JFIELD_PASSWORD_RULES_UPPERCASE', $minUppercase);
	}

	if ($minLowercase)
	{
		$requirements[] = Text::sprintf('JFIELD_PASSWORD_RULES_LOWERCASE', $minLowercase);
	}
}
?>
<?php if (!empty($description)) : ?>
	<div id="<?php echo $name . '-desc'; ?>" class="small text-muted">
		<?php echo Text::sprintf($description, implode(', ', $requirements)); ?>
	</div>
<?php endif; ?>

Add to registration.xml:
description="JFIELD_PASSWORD_RULES_MINIMUM_REQUIREMENTS"

Change:
JFIELD_PASSWORD_RULES_CHARACTERS="Characters: %d"

Add:
JFIELD_PASSWORD_RULES_MINIMUM_REQUIREMENTS="<strong>Minimum Requirements</strong> %s"

@infograf768 Great that you want to change both sets of strings to match

I would prefer the much simpler "numbers" to either "digits" or "integers"

@zero-24
I had figured you would have preferred such a display.
I already had done here a variation, keeping the rules attribute.
Will try your proposal. Evidently, it would imply modifying the J installation password tip as done in #30402 as I am not sure it will get the minimum characters

Will come back after tests.

I'm not sure whether that was for me but to answer your question when you can not get a value from the Database just fallback to the default values ;-)

My proposal would be to show all of that next the message that the PW does not meet the requirements. As all that info should be in JS anyway but that is beyond my knowledge of JS at that point :-D

But by Default it is only the 12 chars so the installer should be fine as it is and should only get the 'do not show the requiremets' xml switch so we do not dublicate that info.

I would prefer the much simpler "numbers" to either "digits" or "integers"

Not sure, digit is a single number. Number may be composed of one or multiple digits.

@zero-24

But by Default it is only the 12 chars so the installer should be fine as it is

I guess so but I also have to modify its description string, i.e. use the value of
description="JFIELD_PASSWORD_RULES_MINIMUM_REQUIREMENTS"
instead of the one of
description="INSTL_ADMIN_PASSWORD_LENGTH"

As I said, will first make a test and close this PR and create a new one.

In English it is perfectly normal and expected to refer to numbers and letters in this use case

Oxford Dictionnary
https://www.lexico.com/definition/digit

Any of the numerals from 0 to 9, especially when forming part of a number.

I will stick to it.

A dictionary and real world usage are very different.

But as you always think you know better about a language that is not your native language just see what everyone else does.

Feel free to write what you want in the french translation but in this use case the correct english is "numbers"

In your list there are almost as many numbers of examples using number than digit
It's not a good way to improve bad habits.
You will be free to change all if you desire in your own PR.

So you found three bad examples to prove your incorrect point.

If google, facebook and twitter all use numbers thats good enough proof for me

Closed in favor of #30473 to implement description tip instead of tooltip.
