Description Katrin Fischer 2013-05-17 08:04:49 UTC
The cardnumber field is limited to 16 in Koha. When you enter a longer cardnumber the number is cut off. When you try to change it adding the missing part, there is no error message shown and your change is just not saved.

Koha should give a useful error message.
Comment 1 Magnus Enger 2013-05-19 21:52:40 UTC
16 sounds quite restrictive - could it be made longer too?
Comment 2 Owen Leonard 2013-05-21 13:02:07 UTC
Here are some steps we could take, individually or in combination:

1. Add a "maxlenth" attribute to the input field.
2. Add some JavaScript validation to warn the user when the limit is reached.
3. Increase the length which can be stored.

If we increase the possible length of a card number what should it be? 50? 100?
Comment 3 Katrin Fischer 2013-05-22 07:56:10 UTC
I think I'd like to see a combination of JavaScript warning and maxlength.

16 seems like a reasonable size for a cardnumber, but not sure if there are use cases where a longer number would be needed.
Comment 4 Aleisha Amohia 2016-01-25 22:58:17 UTC
I don't think this is valid anymore - I am unable to type anything once the card number has reached 16 characters in the input box. Please confirm if this is still valid?
Comment 5 Owen Leonard 2016-01-27 14:37:50 UTC
I can confirm this bug by doing this:

1. Bring up the new patron form.
2. Along with any other required fields, enter '23467890758428435' as the barcode (17 digits).
3. Save the patron record. The barcode will be saved as '2346789075842843' (16 digits, the last digit missing).

I don't get your problem, when I paste that number it removes the 5 straight away from the text box.

Okay, my mistake. When I tested it I could have sworn the field let me put in a longer number. 

Either way, if the user isn't carefully watching the number go in they will not be aware that something is wrong. Imagine scanning a barcode -- will the user visually confirm that the number matches what they scanned?

This isn't something which is necessarily badly broken, it's just something we can do better with.

Bug 10267: Show error message if user tries to enter too many characters for cardnumber

This patch displays a message if the user tries to enter more than the
max number of characters for a cardnumber.

To test:
1) Apply patch and go to Patrons -> New patron
2) Scroll down to Card number
3) Put in any characters. Notice that when you have entered the max
number of characters, you are unable to type any more.
4) If you try to type again, the error message will show up.
5) if you backspace some characters, the message should disappear

Comment 11 Jonathan Druart 2017-04-24 15:33:53 UTC
Aleisha, the last case is wrong, maxlength_cardnumber is evaluated false and the message will be "Card number must not be more than  characters". That should not be possible (because C4::Members::get_cardnumber_length returns max=16), but the code does not make sense as it is.

Moreover you should not use the keypress event but change, that way a paste or delete in the input will update the message as well.

Comment 14 Marcel de Rooy 2017-05-12 06:35:57 UTC
Hmm I do not really understand why we need this message.

You cannot type more than 16 chars or paste them.
There is a hint that it should be between 1 and 16.
Currently, the message shows up at 16 chars. This makes me think that I entered too much chars, but I did not.

I think that if we want to do something on this matter, we need to search for another angle. But I am not convinced that we should; the hint is clear to me. We could allow more than 16 chars and then mark it red or something ?

Owen explains the benefit of a patch like this in Comment 7. It may not be broken and seems very obvious to us, but the point is to make things as clear as possible for the user.

Bug 13178 - cardnumber field length is too short
It expands the card number length to 32.

Tested on BibLibre's sandbox #2

The patch applies as described in Comment #13.
However, now there is a new patch for bug 13178 and it is not taken in count in the current bug, I don't know if I'm supposed to sign it :/

It is impossible to enter more than maxlength_cardnumber characters because the maxlength attribute of the input line makes it impossible. I believe bug 13178, providing flexibility of the max size based on the schema which should be regenerated as needed to match the table's field size, makes this bug obsolete.
Comment 19 Katrin Fischer 2017-08-08 16:04:37 UTC
It's impossible to enter them, but scanning from an ID or c&p from another system you might not know that it has been automatically cut off. This was just thought to provide some help for this case. 

I am signing off.

Comment 21 Jonathan Druart 2017-08-09 17:49:25 UTC
If we increase the size of borrowers.cardnumber to 32 (bug 13178), do we still need this?
Comment 22 Katrin Fischer 2017-08-09 18:44:07 UTC
I haven't tested the other bug, but this is not dependent on the size I think. They still might conflict.

Comment 25 Katrin Fischer 2017-09-01 18:10:12 UTC
The problem is not input - try and copy a longer string in. You won't notice that it has been cut off - with the patch you get a note.
Comment 26 Jonathan Druart 2017-10-24 17:32:38 UTC
With CardnumberLength=16, if I enter a 16 chars length string, I get the warning.
It should display only if > 16, right?

Not quite - you can't actually input more than 16 characters so no warning would show if we made that change, which is the problem already. Having a warning at 16 characters (rather than > 16 characters) just lets the user know that there is a limit in place and that they've reached the max. Does that make sense?

Bug 10267: Display the message only if the user enters too many characters

It seems better to display the warning if the user tries to enter too
many characters in the input.

Test plan:
With max=16
1. Copy/paste a string with 15, 16 and 17 characters
2. Enter a cardnumber of 15, 16, 17 characters
The warning should be displayed only the input overflows
