Any field in profile will not display a 0 value

In fact this a little worse than that, it doesn't accept 0 at all.

The problem is in code like this:

  if ($line = trim($line)) {

When line equal 0, we have if (0) which is FALSE so this value is omitted. Should we write:

I'm not sure on how to correct this (with clean code I mean).

  $line = trim($line);
  if (!empty($line) || $line == '0') {

  //or something like that:
  if (strlen($line = trim($line)) != 0) {

Any news about this?

I have just run into this issue on 6.8 using the profiles module. I need to have the number zero be an option for a select list. When I go to the user profile, the zero is not an option and the options in the select list starts with the number 1.

This looks like a confirmed bug. Any solution will need to go in 7.x first, before being backported to any other affected versions.

what about a wrapper called

<?php
function drupal_trim($string, $charlist = " \t\n\r\x0B") {
  return trim($string, $charlist);
}
?>

or just call trim with the changed charlist, but i guess there a quite some places, where "0" should be displayed too

That faulty status made each and everyone skip this issue.

I ran into this bug too and I think it should be a critical one because it really takes you the ability to insert values into a certain profile field. The problem occurs even if the type of field is textfield.

For me at least, the attached patch did the job.

I will have to correct this comment. It does insert the value "0" in the data base but it doesn't show it in any views because in the IF statement it's value is just passed like:

if($variable)
  print $variable;

instead of

if(isset($variable))
  print $variable;

This should do the work hopefully.

Sorry for the repeated status changes and patch attach but I think now it is better.

As per #5, any fix needs to go in the latest version of Drupal affected and then back-ported from there.

@thedavidmeister - any reason you didn't set this to 8.x?

@thedavidmeister I attached a rough patch for D7. If it passes the tests it should work fine.

@mgifford
Profile was deprecated in 7.x and only included as an upgrade path from 6.x. It was removed in 8.x See https://www.drupal.org/node/874026.

I didn't notice that the last patch wasn't tested. Setting status.

Good to know, thanks!

@dcam is correct. There is no profile module in d8.

I tried but I can't reproduce this on 7.x-dev as I understand it. Could someone update the issue summary with the steps to reproduce this on Drupal 7? According to the current issue summary there is a workaround, so is this is major priority according to the guide. To be critical it would "Render the system unusable and have no workaround", which is not the case.
